The AT89C51RB2-SLSUM is a high-performance 8-bit microcontroller based on the 80C51 architecture, manufactured by Microchip Technology. It offers 16KB of on-chip Flash program and data memory, supporting byte and page erase/write operations with up to 100,000 write cycles. This microcontroller operates at speeds up to 60MHz in standard mode and 30MHz in X2 mode, with a wide operating voltage range of 2.7V to 5.5V.
Key features include 1.25KB of expanded RAM (XRAM), four 8-bit I/O ports, three 16-bit timer/counters, and a 9-source, 4-level interrupt controller. It also incorporates a Programmable Counter Array, a Hardware Watchdog Timer, SPI interface, and an enhanced UART (EUART) for multiprocessor communication. The device is designed for both commercial (0 to +70 °C) and industrial (-40°C to +85°C) temperature ranges.
The AT89C51RB2-SLSUM is available in a 44-PLCC surface-mount package. Its static design allows for clock frequency reduction to DC without data loss, supporting power control modes like Idle and Power-down. This makes it suitable for a variety of embedded control applications requiring a robust and versatile 8-bit MCU.
