AT91SAM9G20 Summary

1. Description

The AT91SAM9G20 is based on the integration of an ARM926EJ-S processor with fast ROM

and RAM memories and a wide range of peripherals.

The AT91SAM9G20 embeds an Ethernet MAC, one USB Device Port, and a USB Host control-

ler. It also integrates several standard peripherals, such as the USART, SPI, TWI, Timer

Counters, Synchronous Serial Controller, ADC and MultiMedia Card Interface.

The AT91SAM9G20 is architectured on a 6-layer matrix, allowing a maximum internal bandwidth

of six 32-bit buses. It also features an External Bus Interface capable of interfacing with a wide

range of memory devices.

The AT91SAM9G20 is an enhancement of the AT91SAM9260 with the same peripheral fea-

tures. It is pin-to-pin compatible with the exception of power supply pins. Speed is increased to

reach 400 MHz on the ARM core and 133 MHz on the system bus and EBI.
