CRD89L51RD 8-Bit Microcontroller with 64KB ISP Flash, 1KB of SRAM

PublishTime：2025-03-16

The CRD89L51RD is an 8-bit microcontroller from Cyrod Technologies Inc. It is based on the standard 8051 microcontroller family architecture and is a pin-compatible drop-in replacement for most 8051 MCUs. It features 64KB of on-chip Flash memory, 1KB of SRAM, an I²C-compatible interface, 2 PWM output channels, a UART, three 16-bit timers, and the ability to exit the power-down mode upon assertion of an external interrupt. It is designed for applications requiring non-volatile data storage and code/field-based firmware upgrade capability. The CRD89L51RD is available in PLCC-44, QFP-44, and PDIP-40 packages and operates over a commercial temperature range.
