Microchip Technology Inc. announced last week that it would continue to manufacture the legacy 8051/80C51 MCUs.

Microchip Technology’s acquisition of Silicon Storage Technology, Inc. (SST) included a legacy 80C51 MCU; Microchip continues to support this project.

“Microchip has a history of supporting customers with long lifetimes on all of our product lines,” said Randy Drwinga, vice president at Microchip Technology Inc. “We also have a strong presence in the industrial, automotive and medical markets, and understand that long-lifecycle product support is important to these customers. We welcome anyone currently using NXP’s 80C51 MCUs who doesn’t wish to redesign their end products to use our 100% compatible 80C51 product portfolio, and we offer them the option to migrate to our broad portfolio of 8-bit, 16-bit and 32-bit PIC® microcontrollers, at their convenience.”

The 8051/80C51 MCU’s provide pin-for-pin compatible replacements for most MCUs placed under the “End-of-Life” notifcation by NXP, which include NXP’s P89LV51RB2/C2/D2 and P89V51RB2/C2/D2 EOL series of 80C51 8-bit microcontrollers.

NXP’s 989LV 3V MCUs are 100% compatible with Microchip Technology’s SST89V MCUs, whereas NXP’s P89V 5V MCUs are pin-for-pin compatible with Microchip Technology’s SST89E microcontrollers.

Microchip Technology’s 80C51 MCUs can be used with many popular third-party development tools, such as Xeltek, Hi-Lo Systems, Advantech Eqipment Corp., EETools and Phyton.

These MCUs are available for $1.22 each, in 10,000-unit quantities.

Microchip Technology is a provider of MCU, analogy and Flash-IP solutions. The company provides low-risk product development and is headquartered in Chandler.
