The AT89C51AC3-SLSUM is an 8-bit microcontroller from Microchip Technology (formerly Atmel) based on the 80C51 core architecture. It features 64KB of on-chip Flash memory for program storage, 2KB of EEPROM for non-volatile data, and 2304 bytes of RAM (including 256 bytes of standard RAM and 2048 bytes of ERAM). The device operates at clock speeds up to 40 MHz in standard mode (3V to 5.5V) and up to 60 MHz when running internal code at 4.5V to 5.5V.
This microcontroller includes a rich set of peripherals: a 10-bit ADC with 8 multiplexed inputs, three 16-bit timers/counters, a 5-channel 16-bit PCA with PWM capability, a full-duplex UART, a 21-bit watchdog timer, and 36 general-purpose I/O lines. It also features an integrated power monitor (POR/PFD), in-system programming via UART bootloader, and power-saving modes (Idle and Power-down).
Housed in a 44-lead PLCC package (J-Lead), the AT89C51AC3-SLSUM is designed for surface-mount assembly. It operates over the industrial temperature range of -40°C to 85°C, making it suitable for harsh environments. The device is RoHS compliant and lead-free. With its combination of memory, analog, and digital peripherals, it is well-suited for industrial control, automotive, and embedded applications.
