Product Details

Microchip's ARM®-based SAM7SE256 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 256KB of 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. It achieves single-cycle instruction access from embedded flash at 27 MIPS.
