AT91SAM7S512B-AU

The AT91SAM7S512B-AU is a 16/32-bit microcontroller from Microchip Technology based on the ARM7TDMI processor core. It operates at a maximum clock frequency of 55 MHz and features 512 KB of on-chip Flash memory organized as two contiguous banks of 1024 pages of 256 bytes (dual plane) and 64 KB of SRAM. The device includes a rich set of peripherals: brown-out detect/reset, DMA, POR, PWM, and watchdog timer. Connectivity options include I²C, SPI, SSC, UART/USART, and USB. It provides 32 general-purpose I/O pins.

The microcontroller is supplied with a voltage range of 1.65V to 1.95V and includes an internal oscillator. It incorporates an 8-channel 10-bit ADC for analog data conversion. The operating temperature range is -40°C to 85°C, making it suitable for industrial environments. The device is housed in a 64-LQFP package with a 10x10 mm body, designed for surface-mount assembly.

The Flash memory features dual-plane organization for efficient programming, and the SRAM provides single-cycle access at maximum speed. The microcontroller supports various power management modes including slow clock and idle modes for optimization. It is suitable for applications requiring a balance of performance, memory, and connectivity in a compact package.
