P89V51RD2FN Description

Short technical summary and product information.

The NXP P89V51RD2FN is an 8-bit microcontroller featuring an 80C51 CPU core. It provides 16/32/64 kB of on-chip flash user code memory and 1024 B of data RAM. This microcontroller supports dual clock modes: the conventional 12 clocks per machine cycle or an X2 mode with six clocks per machine cycle for increased throughput or reduced EMI.

 

Key features include SPI and enhanced UART interfaces, a PCA module with PWM and capture/compare functions, and three 16-bit timers/counters. It has four 8-bit I/O ports, with three high-current port 1 pins capable of 16 mA each. The device also includes a programmable watchdog timer, eight interrupt sources with four priority levels, and a second DPTR register.

 

Designed for 5V operation, the P89V51RD2FN can run from 0 MHz to 40 MHz. It supports In-System Programming (ISP) and In-Application Programming (IAP) for flexible firmware updates. Low power modes, including power-down and idle modes, are available. The microcontroller is available in a DIP40 package, suitable for through-hole mounting.
