Chandler, Ariz., U.S.: Microchip will continue to manufacture legacy 8051/80C51 MCUs that provide pin-for-pin compatible replacements for most of those MCUs recently placed under “End-of-Life” (EOL) notification by NXP.
Included are drop-in replacements for NXP’s P89LV51RB2/C2/D2 and P89V51RB2/C2/D2 EOL series of 80C51 8-bit microcontrollers. NXP’s P89LV versions are 3-V MCUs that are 100% compatible with Microchip’s SST89V MCUs. Likewise, NXP’s P89V versions are 5-V MCUs that are pin-for-pin compatible with Microchip’s SST89E microcontrollers.
Microchip’s 2010 acquisition of Silicon Storage Technology (SST) included a legacy 80C51 MCU business, which Microchip has continued to support.
