AT91SAM7XC512B-AU Description

Short technical summary and product information.

The AT91SAM7XC512B-AU is a high-performance 16/32-bit microcontroller from Microchip Technology, built around the ARM7TDMI core. It runs at speeds up to 55MHz and is supplied in a 100-LQFP package, designed for surface-mount assembly. The device provides 512KB of dual-bank flash memory and 128KB of static RAM, both with single-cycle access where applicable. It operates from a low supply voltage of 1.65V to 1.95V, supporting low-power embedded designs.

 

Peripheral features include brown-out detection and reset, DMA, PWM, watchdog timer, and power-on reset. The MCU integrates an 8-channel 10-bit A/D converter for analog sensing. For connectivity, it offers CANbus, Ethernet, I²C, SPI, SSC, UART/USART, and USB interfaces, making it suitable for networked control applications. An internal oscillator simplifies the clock design.

 

With 62 I/O lines and a temperature range of -40°C to 85°C, the AT91SAM7XC512B-AU can be deployed in industrial, automotive, and communication environments. The 100-LQFP package provides adequate I/O density while remaining manageable for standard PCB assembly processes.
