ATSAM4S8BA-MU Description

Short technical summary and product information.

The ATSAM4S8BA-MU is a 32-bit microcontroller based on the ARM Cortex-M4 core with FPU, operating at 120 MHz. It belongs to the SAM4S family and integrates 512 KB of Flash memory with a read accelerator and 128 KB of SRAM. The device includes a multi-layer bus matrix and 21-channel DMA controller for efficient data movement.

 

Connectivity options include USB device, SDIO/SD/MMC, three SPI, two I2C, I2S, two USART, and two UART interfaces. Analog peripherals consist of a 12-bit ADC with 11 channels, a 12-bit DAC with 2 channels, a temperature sensor, and an analog comparator. Additional peripherals include brown-out detect/reset, POR, PWM, and watchdog timer.

 

The microcontroller is supplied in a 64-VFQFN exposed pad package (64-QFN 9x9 mm) for surface mount assembly. It operates from 1.62 V to 3.6 V and over a temperature range of -40°C to 85°C. The SAM4S series offers pin-to-pin compatibility with other SAM families for easy migration.
