1. Description
6384DS–ATARM–13-Jan-10
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.
