Description

General part information

AT91SAM7SE512 Series

Microchip's ARM®-based SAM7SE512 is a member of the SAM7SE series of flash microcontrollers based on the 32-bit ARM7TDMI RISC processor.

It operates at a maximum speed of 55MHz and features 512KB of dual-bank flash memory and 32KB of SRAM.

The peripheral set includes an external bus interface (EBI) supporting static memory, ECC-enabled NAND, CompactFlash and SDRAM, UART, two USARTs, TWI (I2C), SPI, SSC, four 16-bit PWM controllers, three 16-bit timers, an RTT and one 8x10-bit ADC.
