AT89C51RC2-3CSUM Description

Short technical summary and product information.

The AT89C51RC2-3CSUM is a high-performance 8-bit microcontroller from Microchip Technology, based on the 80C51 architecture. It offers 32KB of on-chip Flash program and data memory, along with 1.25KB of expanded RAM (XRAM). This device supports a maximum clock speed of 60MHz in standard mode with internal code execution and a 4.5V to 5.5V supply.

 

Key features include 32 general-purpose I/O pins, an SPI interface, and a full-duplex enhanced UART (EUART) with a dedicated baud rate generator. It also incorporates peripherals such as a Power-On Reset (POR) circuit, Pulse Width Modulator (PWM), and a Hardware Watchdog Timer (WDT). The microcontroller operates over a wide temperature range of -40°C to 85°C.

 

Designed for through-hole mounting, the AT89C51RC2-3CSUM comes in a 40-pin PDIL package. Its flexible power supply requirement ranges from 2.7V to 5.5V, making it suitable for various embedded applications. The device supports in-system programming (ISP) capabilities using the standard VCC power supply.

 

This microcontroller is compatible with the 80C52 standard, offering features like four 8-bit I/O ports, three 16-bit timer/counters, and a dual data pointer. Its high-speed architecture and advanced peripherals make it a versatile choice for complex embedded systems.
