Product Details
Microchip Technology Microcontroller
The Microchip technology AT91 family type, LQFP package, surface mount, 100-pin ARM7TDMI 32-bit microcontroller has a maximum voltage rating of 3.6 V. It operates at a maximum speed of 55MHz and features 512kb flash and 128kb of SRAM. The 512kb of flash is split into two banks of 256kb. The peripheral set includes USB 2.0 full-speed device port, Ethernet MAC 10/100 port, two USART, UART, two SPI, SSC, TWI (I2C), three 16-bit timers, RTT and 8x10-bit ADC. It has 62 programmable I/O lines multiplexed with up to two peripheral I/Os.
