AVR Typen

84.73.217.139: /* ATmega */ Typo in der ersten Aufzählungsliste (Kibibyte -> Kilobyte)

== AT90S ==
Die "Basic Line" der Atmel [[AVR]]-Reihe. Sie beinhaltet die ersten [[AVR|AVRs]] die produziert wurden und deren Bezeichnung mit "AT90S" beginnt. Alle Typen wurden mit der Zeit von den beiden Nachfolgereihen ersetzt: ATmega bzw. ATtiny.

Einige neue AVR-Controller tragen eine mit AT90-''ohne S'' beginnende Bezeichnung, haben aber einen "moderneren" Kern. Z.B. sind die Typen AT90PWM2/3 und AT90CAN128 vom Funktionsumfang (interner RC, USART etc.) den ATmegas zuzuordnen.

== ATmega ==
Die ATmega-[[Mikrocontroller]] sind ein Teil der AVR-Controllerfamilie. Zusammen mit den ATtiny lösen die ATmega die AT90S-Serie schrittweise ab, wobei es in den meisten Fällen weitgehend pin- und funktionskompatiblen Ersatz für abgekündigte Controller gibt (ATmega8 bzw. ATmega8A statt AT90S4433, ATmega8515 statt AT90S8515 usw.).

Atmel ATmega AVRs werden mit aktiviertem internem Taktgeber ausgeliefert. Schließt man eine andere externe Taktquelle an (Quarz, Quarzoszillator o.ä), wird diese nicht automatisch genutzt. Zum Aktivieren müssen die Fuse-Bits des Controllers entsprechend eingestellt werden (siehe Datenblatt).

ATmegas mit integriertem [[JTAG]]-Interface (z.Zt. solche ab 16kB Flash-Speicher und mehr als 28 Pins) werden ab Werk mit aktiviertem JTAG-Interface ausgeliefert. Dieses Interface belegt vier Port-Pins (z. B. am PORTC bei ATmega16/32), die nicht für eigene Anwendungen genutzt werden können, solange das JTAG-Interface aktiviert ist. Das Interface lässt sich über ein Fuse-Bit (JTAGEN) dauerhaft und über ein Bit (JTD) in dem (oder einem der) MC-Kontroll-Register (Datenblatt nach JTD durchsuchen) per Software zur Laufzeit an- und abschalten. Weiteres im Datenblatt des jeweiligen Controllers in den Abschnitten Memory-Programming (Fuse) und JTAG/ICE (JTD).

Beim ATmega128 ist ab Werk die Mega103-Kompatibilitäts-fuse gesetzt. Um alle Erweiterungen des Mega128 gegenüber dem Mega103 zu nutzen muss diese deaktivert werden. Diese Fuse sorgt außerdem dafür, dass das SRAM in einem anderen Adressbereich liegt. Dadurch funktionieren C-Programme nur bis zum ersten Funktionsaufruf. Siehe auch [[AVR_Checkliste#Besonderheiten_bei_ATmega128_und_seinen_Derivaten_im_64-Pin-Gehäuse | AVR Checkliste: Besonderheiten bei ATmega64 / ATmega128]]

== ATtiny ==

Die ATtiny stellen das untere Ende der neuen AVR Linie von Atmel dar und waren zunächst durch das Fehlen von internem [[RAM#SRAM|SRAM]] gekennzeichnet. Mittlerweile gibt es aber so bemerkenswerte Controller wie den ATtiny4313, deren Möglichkeiten und Funktionen den ATmegas in nichts nachstehen.

Ein weiterer Unterschied zu den ATmegas ist der fehlende Hardwaremultiplizierer. Jede Multiplikation muss also in Software ausgeführt werden. Eine Übersicht über die Verfügbarkeit verschiedener Befehle bietet die [[AVR_Assembler_-_Vergleichstabelle|AVR-Assembler Befehlsvergleichstabelle]].

== ATxmega ==
Neueste Generation von AVR-Controllern mit neuem internen Aufbau, hoher Taktrate (32 MHz), niedriger Spannung (1,6 - 3,6V), vielen Schnittstellen, in 44 - 100 poligen SMD-Gehäusen. Besonderheiten: ADC mit 2 Megasample/12 Bit, vierpoliges Programm- und Debug- Interface PDI (VTref, CLK, DATA, GND) erfordert z.B. einen AVR_JTAGICE-mkII Programmer. PDI (Flash und Debug) funktioniert mit C-Code z.B. mit AVR Studio 4.19.

Leider ist die Xmega-Reihe zu den AVR-Prozessoren der Mega- oder Tiny-Serien nicht kompatibel (viel komplizierter, anderer Aufbau der IO-Baugruppen, der Interrupts, der C-Funktionen etc.). Prozessor-Manuals zeigen weder Assembler noch C-Beispiele für Ansteuerung der IO-Baugruppen. C-Programmbeispiele (geeignet für AVR-Studio) findet man erst in Xmega Application Notes. Einen Überblick gibt es von [http://www.stromflo.de/dokuwiki/doku.php?id=xmega-c-tutorial Florian Grotz] oder in dem [http://www.jtronics.de/avr-projekte/xmega-tutorial.html jtronics Xmega Tutorial] .

== Sonstiges ==

Die AT89-Familie gehört nicht zu den AVR-Typen mit dem AVR-RISC-Befehlssatz, sondern ist eine [[8051|Intel-8051]]-kompatible 8-Bit µC-Serie.

=== Tiny vs Mega ===
Die modernen Typen sind die Tiny (=winzig) und die Mega (=riesig). Die ATTiny haben kleinere Gehäuse als die ATMega, mit weniger Pins. Dies führt bei ähnlicher Funktionalität wie die Megas zu extremen Mehrfachbelegungen der Pins und auch eher zu Überschneidungen der Pinfunktionalität. Die Tiny sind daher eher für sehr hohe Stückzahlen geeignet, wo die Einsparung über die Stückzahl kommt. Anfänger und Bastler sind mit den ATMega besser bedient, da die weniger Limitationen besitzen.

Tinys haben keinen Hardware-Multiplizierer.

==Nomenklatur==
===ATmega===
Auch wenn die Namensgebung auf den ersten Blick bedingt durch die vielen verfügbaren Modelle kompliziert aussieht, so folgt sie doch immer (von wenigen Ausnahmen abgesehen) einem einfachen Schema.

Nehmen wir einen aktuellen Baustein als Beispiel: *ATmega48PA-AU*. Der Name besteht aus 5 Teilen:
# Der Baureihe (hier: "ATmega")
# Einer Nummer, immer eine Zweierpotenz (hier: 4). Diese Zahl gibt die Größe des Flashspeichers in Kilobyte an.
# Bis zu zwei weiteren Ziffern (hier: 8). Sie definieren die Zusatzfunktionen sowie Zahl der I/O-Ports.
# Bis zu zwei Buchstaben (hier: PA), die für die Revision sowie spezielle stromsparende Architekturen stehen.
# Einem Bindestrich und zwei weiteren Buchstaben, die die Bauform angeben (hier: AU).

====Baureihe====

Hier gibt es nur zwei Reihen: Den kleinen ATtiny mit reduziertem Funktionsumfang und den großen ATmega.

====Speichergröße====

Während die Größe des Flashspeichers (Programmspeicher) direkt im Namen angegeben ist, ergibt sich die Größe von RAM und EEPROM nur indirekt aus dieser Nummer, wobei natürlich die Bausteine mit großem Flash auch mehr RAM und EEPROM haben als kleinere. Grob gilt diese Zuordnung:

{| class="wikitable"
|-
! Flash (kB) !! EEPROM (B) !! RAM (B)
|-
| 2 || tiny: 128 || tiny: 128
|-
| 4 || tiny: var., mega: 256 || tiny: 256, mega: 512
|-
| 8 || tiny: var., mega: 512 || tiny: 512, mega: 1024
|-
| 16 || 512 || 1024
|-
| 32 || 1024 || 2048
|-
| 64 || 2048*) || 4096*)
|-
| 128 - 256 || 4096 || 4K - 16K
|}
*)Atmega640 verfügt über den doppelten Speicher

====Zusatzfunktionen / Größe====
Die Ziffer(n) nach der Flashgröße geben die Ausstattungsmerkmale des Bausteins an. Die folgende Tabelle gilt für die Atmega-Reihe:
{| class="wikitable"
|-
! Ziffer !! Beschreibung
|-
| - || Keine Ziffer markiert die Bausteine der ersten Generation. Sie verfügen in der Regel über eine niedrigere maximale Taktrate (8/16 MHz anstatt 10/20 MHz), eine höhere Minimal-Spannung (2,7 anstatt 1,8 Volt), weniger Interrupt-Quellen und PWM-Kanäle
|-
| 0 || Reihe von 32 - 256 kB in einem größeren Gehäuse mit höherer Anzahl an I/O-Pins. Etwas älter als die aktuellen Reihen 4 und 8.
|-
| 1 || Kennzeichnet eine verbesserte Version des Atmega128 / 256, aber älter als aktuelle 4er Reihe
|-
| 4 || Reihe von 16 bis 128 kB Flash, alle pinkompatibel in 40-44 poligem Gehäuse. Neueste Baureihe, alle in pico-power-Technologie mit vielen verbesserten Funktionen wie externen Interrupts, Timern, USART...
|-
| 5 || Reihe von 16 bis 64 kB
|-
| 8 || Reihe von 4 bis 32 kB, alle pinkompatibel in 28-32 poligem Gehäuse. Neueste Baureihe, alle in pico-power-Technologie mit vielen verbesserten Funktionen wie externen Interrupts, Timern, USART.... (auch in der Attiny-Reihe vorhanden)
|-
| 9 || Reihe von 16 bis 64 kB mit integriertem Controller für LC-Displays, folglich in großen Gehäusen (64-/100-polig)
|}
Aus dieser Liste stechen einige Bausteine als Außenseiter hervor:
* Atmega8515 / Atmega8535
* Atmega640: Im Prinzip ein Atmega64 mit deutlich mehr Hardware-Ressourcen (4 UARTs, 16 ADC-Kanäle...) und doppelt soviel EEPROM / SRAM.

====Revision / Architektur====
Die (optionalen) Buchstaben vor dem Bindestrich geben Auskunft über den Stromverbrauch und Spannungsbereich
{| class="wikitable"
|-
! Buchstabe !! Beschreibung
|-
| A || Zweite Revision - meist nur eine Umstellung der internen Strukturen ohne Auswirkung für den Benutzer
|-
| L / V || "Low-Voltage": Speziell für niedrigere Taktraten (8 bzw. 10 MHz) sowie niedrigere Eingangsspannungen (1,8 bzw. 2,7V) selektierte Bausteine
|-
| P/PA || "Pico-Power": Reduzierter Stromaufnahme, besonders in tiefen Sleep-Modes (< 1uA); Manche Bausteine (z.B. Mega48) gibt es als P und PA
|}

==== Bauform====
Die beiden Buchstaben nach dem Bindestrich geben Auskunft über die Bauform. Die Zahl der Pins des jeweiligen Gehäusetyps hängt vom Baustein ab.
{| class="wikitable"
|-
! Buchstaben !! Beschreibung
|-
| A || TQFP-Gehäuse
|-
| C || BGA-Gehäuse
|-
| I || Bleihaltig - nicht mehr erhältlich
|-
| J || PLCC-Gehäuse
|-
| M || (V)QFN- / MLF- Gehäuse
|-
| P || DIP-Gehäuse (bastlerfreundlich!)
|-
| S || SOIC-Gehäuse
|-
| U || Bleifrei, RoHS-kompatibel
|-
| X || TSSOP-Gehäuse
|}

===ATtiny===
Bei den ATtiny-Bausteinen ist die Nummerierung deutlich unübersichtlicher als in der ATmega-Reihe. Die erste Ziffer gibt wie auch bei ATmega die Größe des Flash-Speichers an. Die obenstehenden Tabellen für Baureihe, Bauform, Revision und Speichergröße gelten ebenfalls (Ausnahmen: ATtiny5 mit 0,5 Kilobytes Flash sowie ATtiny4 und ATtiny9 mit 0,5 bzw. 1 kB Flash). Die Zusatzfunktionen und Baugröße sind aber nicht deutlich
