AT91SAM7SE32B-AU Description

Short technical summary and product information.

The AT91SAM7SE32B-AU is a high-performance 16/32-bit microcontroller built around the ARM7TDMI ARM Thumb processor core. It operates at up to 55 MHz and features 32 KB of internal Flash memory organized as a single bank of 256 pages of 128 bytes, with a page programming time of 6 ms including auto-erase. The device includes 8 KB of internal high-speed SRAM with single-cycle access at maximum speed.

 

This MCU integrates a rich set of peripherals including brown-out detect/reset, power-on reset (POR), PWM, and watchdog timer (WDT). Connectivity options include EBI/EMI, I2C, SPI, SSC, UART/USART, and USB. It also features an 8-channel 10-bit analog-to-digital converter and an internal oscillator.

 

The device is housed in a 128-lead LQFP package with gull-wing terminals, suitable for surface-mount assembly. It operates over an industrial temperature range of -40°C to 85°C and requires a supply voltage between 1.65V and 1.95V. The Flash memory supports 10,000 erase cycles and 10-year data retention.
