CRD89x51RC 8-Bit Microcontroller with 32KB Flash, 1KB of SRAM

PublishTime：2025-03-16

The CRD89x51RC is an 8-bit microcontroller designed for a wide range of applications requiring medium amounts of program/data memory. It is based on the standard 80C51 MCU family architecture and is pin compatible with most 8051 MCUs. The microcontroller features 32KB of Flash memory, 1KB of SRAM, 5 PWM output channels, a UART, three 16-bit timers, a watchdog timer, and power-down features. It also includes a fifth, 4-bit I/O port mapped into the "no connect" pins of the standard 8051/52 package, providing a total of 36 I/Os while maintaining compatibility with standard 80C51/52 pinouts.
