P89V51RD2FN

The NXP Semiconductors P89V51RD2FN is an 8-bit microcontroller featuring an 80C51 CPU core. It is equipped with 64kB of on-chip flash user code memory and 1kB of data RAM. This microcontroller supports operating voltages from 0 MHz to 40 MHz and offers a flexible clock mode selection between the conventional 12-clock and the high-throughput 6-clock per machine cycle.

Key features include integrated SPI and enhanced UART interfaces, a PCA module with PWM and capture/compare functions, and four 8-bit I/O ports. It also includes three 16-bit timers/counters, a programmable watchdog timer, and eight interrupt sources with four priority levels. The device supports In-System Programming (ISP) and In-Application Programming (IAP) for flexible firmware updates.

Designed for various applications, the P89V51RD2FN includes low power modes such as power-down and idle modes. It also features brownout detection and a low EMI mode. The microcontroller is available in DIP40, PLCC44, and TQFP44 packages, supporting through-hole mounting.

This device is suitable for embedded systems requiring a robust 80C51 architecture with ample flash memory and versatile communication peripherals. Its ability to operate at high frequencies while offering low power consumption makes it a practical choice for a wide range of electronic designs.
