The Microchip Technology AT91SAM7S321-MU is a 32-bit RISC microcontroller featuring an ARM7TDMI core operating at up to 55MHz. This device integrates 32KB of Flash program memory and 8KB of on-chip SRAM, with an 8-bit program memory bus width. Connectivity options include SPI, SSC, TWI, and USART interfaces, alongside 9 DMA channels for efficient data transfer. Peripheral support encompasses a 10-bit, 8-channel Analog-to-Digital Converter (ADC), multiple timers including PWM capabilities, and a Watchdog Timer (WDT). Low-power modes are incorporated for energy-sensitive applications. The AT91SAM7S321-MU is housed in a 64-lead HVQFN package, suitable for surface-mount assembly within an operating temperature range of -40°C to +85°C. This component finds application in industrial automation, consumer electronics, and medical devices.
