AT91SAM7A3-AU Description

Short technical summary and product information.

The AT91SAM7A3-AU is a high-performance microcontroller from Microchip Technology based on the ARM7TDMI processor core. It operates at speeds up to 60MHz and provides 256KB of internal Flash memory organized in 1024 pages of 256 bytes, with single-cycle access at up to 30MHz. The device also includes 32KB of internal single-cycle SRAM.

 

The microcontroller integrates a comprehensive set of peripherals including two CAN 2.0B controllers, a USB 2.0 Full Speed device port, multiple serial interfaces (CAN, I2C, SPI, SSC, UART/USART), an 8-channel 10-bit ADC, and an 8-channel 20-bit PWM controller. It also features 19 Peripheral DMA Controller channels for efficient data transfers.

 

Packaged in a 100-LQFP (14x14 mm) surface-mount package, the AT91SAM7A3-AU operates over a supply voltage range of 1.65V to 1.95V and a temperature range of -40°C to +85°C. The device includes power management features such as idle, standby, and backup modes, making it suitable for battery-powered and industrial applications.
