AT91SAM7SE32-AU

The AT91SAM7SE32-AU is a high-performance 16/32-bit microcontroller based on the ARM7TDMI processor core. It operates at up to 55 MHz and includes 32KB of internal Flash memory (organized as 256 pages of 128 bytes, single plane) and 8KB of SRAM. The Flash memory offers 10,000 erase cycles and 10-year data retention, with page programming time of 6 ms.

This microcontroller integrates a rich set of peripherals including brown-out detect/reset, power-on reset, PWM, and watchdog timer. Connectivity options include EBI/EMI for external memory, I²C, SPI, SSC, UART/USART, and USB. It also features an 8-channel 10-bit ADC and an internal oscillator. The device is supplied in a 128-LQFP package (20x14 mm) with surface mount mounting and 88 I/O pins.

Additional features from the datasheet include a memory controller with Flash controller and memory protection unit, a reset controller, clock generator with low-power RC oscillator and PLL, power management controller with slow clock and idle mode, and an advanced interrupt controller with eight-level priority. The operating voltage range is 1.65V to 1.95V, and the operating temperature range is -40°C to 85°C.
