... The processor's internal architecture and the ARM and Thumb instruction sets are described in the ARM7TDMI Datasheet. AMC: Advanced The AT91SAM7A2 embeds 16 Kbytes of internal SRAM. The internal memory is directly con- Memory Controller nected to the 32-bit data bus and is single-cycle accessible. This provides maximum performance of 27 MIPS @ 30 MHz by using the ARM® ...

... As for the USART, a two-channel PDC is used to move data directly between memory and the SPI without CPU intervention for maximum real-time processing throughput. CAN: Controller The AT91SAM7A2 provides four CANs (2.0A and 2.0B). These are based upon serial commu- Area Network nications protocol which efficiently supports distributed real-time control with a very high level of security (one with 32 mailboxes and the others with 16 mailboxes) ...

... This allows a 32-bit register to have sufficient range to cater for hour period. WD: Watch Dog The AT91SAM7A2 has an internal watchdog which can be used to prevent system lock-up if the software becomes trapped in a deadlock. SFM: Special The AT91SAM7A2 provides registers which implement the following special functions. ...

... The ADC can be configured to automatically enter Sleep Mode after a conversion sequence, and can be triggered by the software. The ADC allows a data transfer with the PDC. PMC: Power The AT91SAM7A2 Power Management Controller allows optimization of power consumption. The PMC enables/disables the clock inputs of the PDC and ARM core. Moreover, the main Management ...
