The Microchip Technology AT91SAM7S64B-AU is a 32-bit RISC microcontroller featuring an ARM7TDMI core operating at speeds up to 55MHz. This device integrates 64KB of Flash program memory and 16KB of on-chip SRAM. Connectivity options include SPI, SSC, TWI, and two USARTs. For system control and monitoring, it incorporates peripherals such as Brown-Out Detection (BOD), Power-On Reset (POR), and a Watchdog Timer (WDT). The AT91SAM7S64B-AU also provides 11 DMA channels for efficient data transfer and 8 channels of 10-bit Analog-to-Digital Converters (ADCs). This CMOS component is housed in a 64-lead, low-profile, fine-pitch Quad Flat Pack (LFQFP) with a 0.50mm terminal pitch. It supports low-power modes and operates within an industrial temperature range of -40°C to +85°C, with a supply voltage range of 1.80V to 1.95V. Applications span industrial automation, consumer electronics, and communication systems.
