AT91SAM7S128C-AU Description

Short technical summary and product information.

The AT91SAM7S128C-AU is a 16/32-bit ARM7 microcontroller from Atmel, designed for embedded applications requiring a balance of performance and low power. It features a 55 MHz ARM7 core, 128KB of Flash program memory, and 32KB of RAM. The device includes 32 general-purpose I/O pins and a rich set of peripherals: Brown-out Detect/Reset, DMA, POR, PWM, and WDT. Connectivity options include I2C, SPI, SSC, UART/USART, and USB, making it suitable for communication-intensive designs. An 8-channel 10-bit ADC is integrated for analog signal acquisition. The microcontroller operates from a 1.65V to 1.95V supply and over a temperature range of -40°C to 85°C. It is offered in a 64-LQFP (10x10) surface mount package, suitable for compact PCB layouts. The internal oscillator eliminates the need for external clock components. This part is RoHS3 compliant (unverified).
