Microchip's ARM?-based SAM7SE32 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 32KB of flash memory and 8KB 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. The multi-layer bus matrix, multiple SRAM banks, PDC, and DMA support parallel tasks and maximize data throughput.The SAM7SE32 operates from 1.65V to 3.6V and is available in 144-pin LFBGA and LQFP 128-pin packages.\n类似型号AT91SAM7SE32B-CUR, AT91SAM7SE32B-AU, AT91SAM7SE32B-AUR, AT91SAM7SE32B-CU
