P89V51RD2 - 40MHz Microcontroller 8-bit [Original]

P89V51RD2 - High-Performance 40MHz 8-bit 80C51 Microcontroller

The P89V51RD2 is a high-performance 80C51 microcontroller, offering robust capabilities for a wide range of embedded applications. It integrates 64 KB of on-chip flash memory and 1024 bytes of data RAM, providing ample resources for complex projects. A standout feature is its innovative X2 mode, allowing designers to double throughput at the same clock frequency or significantly reduce EMI by halving the clock. This flexibility optimizes performance and power efficiency. The flash memory supports both high-speed parallel programming and In-System Programming (ISP), enabling convenient field updates. With its versatile features and reliable architecture, the P89V51RD2 is an excellent choice for modern electronic designs.
