Microchip Technology's AT91SAM7S161-AU is a 32-bit RISC microcontroller featuring an ARM7TDMI core operating at up to 55MHz. This device is equipped with 16KB of FLASH program memory and 4KB of on-chip SRAM. Peripheral set includes nine DMA channels, three timers, a Watchdog Timer (WDT), and Power-On Reset (POR) circuitry. Connectivity options are extensive, incorporating SPI, SSC, TWI, and USART interfaces. The AT91SAM7S161-AU also provides 8 channels of 10-bit Analog-to-Digital Converters (ADCs) and multiple PWM channels. Designed for embedded applications, it supports low-power modes and operates over an industrial temperature range of -40°C to +85°C. The component is housed in a 64-lead LFQFP package with a 0.5mm terminal pitch. This microcontroller is suitable for various industrial automation, consumer electronics, and communication systems.
