AT91SAM7X256C-AUR MICROCHIP Microcontroller
The AT91SAM7X256C-AUR is a 32-bit ARM7TDMI-based Flash MCU from Microchip, operating at up to 55 MHz and housed in a 100‑pin LQFP package. For selection, verify a core voltage (Vcc/Vdd) of 1.65 V to 1.95 V and an industrial operating temperature of –40 °C to +85 °C (TA). The integrated voltage regulator enables a single 3.3‑V supply with 5‑V tolerant I/Os. Confirm 256‑KB Flash and 64‑KB SRAM meet firmware and data needs. Key connectivity includes CAN 2.0A/B, Ethernet MAC 10/100, USB 2.0 FS, two USARTs, UART, two SPI, SSC, TWI (I²C), and an 8‑channel 10‑bit ADC. Ideal for industrial automation, real‑time motor drives, smart sensor networks, building control, automotive body electronics, medical instruments, and networked embedded systems.
