8-bit Atmel Microcontroller with 64/128Kbytes of ISP Flash and USB Controller

Atmel Corporation 

Features

• High performance, low power AVR® 8-bit Microcontroller

• Advanced RISC architecture

– 135 powerful instructions – most single clock cycle execution

– 32 × 8 general purpose working registers

– Fully static operation

– Up to 16MIPS throughput at 16MHz

– On-chip 2-cycle multiplier

• Non-volatile program and data memories

– 64/128Kbytes of in-system self-programmable flash

• Endurance: 100,000 write/erase cycles

– Optional Boot Code section with independent lock bits

• USB boot loader programmed by default in the factory

• In-system programming by on-chip boot program hardware activated after

reset

• True read-while-write operation

• All supplied parts are pre-programed with a default USB bootloader

– 2K/4K (64K/128K flash version) bytes EEPROM

• Endurance: 100,000 write/erase cycles

– 4K/8K (64K/128K flash version) bytes internal SRAM

– Up to 64Kbytes optional external memory space

– Programming lock for software security

• JTAG (IEEE std. 1149.1 compliant) interface

– Boundary-scan capabilities according to the JTAG standard

– Extensive on-chip debug support

– Programming of flash, EEPROM, fuses, and lock bits through the JTAG interface

• USB 2.0 full-speed/low-speed device and on-the-go module

– Complies fully with:

– Universal serial bus specification REV 2.0

– On-the-go supplement to the USB 2.0 specification rev 1.0

– Supports data transfer rates up to 12Mbit/s and 1.5Mbit/s

• USB full-speed/low speed device module with interrupt on transfer completion

– Endpoint 0 for control transfers: up to 64-bytes

– Six programmable endpoints with in or out directions and with bulk, interrupt or

isochronous transfers

– Configurable endpoints size up to 256bytes in double bank mode

– Fully independent 832bytes USB DPRAM for endpoint memory allocation

– Suspend/resume interrupts

– Power-on reset and USB bus reset

– 48MHz PLL for full-speed bus operation

– USB bus disconnection on microcontroller request

• USB OTG reduced host:

– Supports host negotiation protocol (HNP) and session request protocol (SRP) for

OTG dual-role devices

– Provide status and control signals for software implementation of HNP and SRP

– Provides programmable times required for HNP and SRP

• Peripheral features

– Two 8-bit timer/counters with separate prescaler and compare mode

– Two16-bit timer/counter with separate prescaler, compare- and capture mode
