1. Description
The AT91SAM9R64/RL64 device is based on the integration of an ARM926EJ-S processor with
a large fast SRAM and a wide range of peripherals.
The AT91SAM9R64/RL64 embeds one USB Device High Speed Controller, one LCD Controller
(for AT91SAM9RL64 only), one AC97 controller, a 2-channel DMA Controller, four USARTs, two
SSCs, one SPI, two TWIs, three Timer Counter channels, a 4-channel PWM generator, one Mul-
timedia Card interface and a 6-channel Analog-to-digital converter that also provides touch
screen management.
The AT91SAM9R64/RL64 is architectured on a 6-layer bus matrix. It also features an External
Bus Interface capable of interfacing with a wide range of memory and peripheral devices.
Some features are not available for AT91SAM9R64 in the 144-ball BGA package.
Separate block diagrams and PIO multiplexing are provided in this document. Table 1-1 lists the
features and signals of AT91SAM9RL64 that are not available or partially available for
AT91SAM9R64. When the signal is multiplexed on a PIO, the PIO line is specified.
