MCUs Switch To ROM In A Flash

Enabling seamless switching between ROM and flash versions, the PIC16CR73, PIC16CR74, PIC16CR76, and PIC16CR77 (PIC16CR7X) general-purpose ROM microcontrollers are interchangeable options for the PIC16F73, PIC16F74, PIC16F76, and PIC16F77 (PIC16F7X) flash devices. Users now have the option of switching between flash and ROM types throughout development and production, resulting in shorter time-to-market, reduced scrap, and lower costs. With the flash socket-compatibility of the PIC16CR7X ROM MCUs, users can run flash during development and production ramp-up, run high volume with ROM, and then ramp-down in flash. Also, the same development tools serving existing PIC flash microcontrollers support the ROM PIC chips. These include MPLAB IDE and MPLAB ICD 2. The PIC16CR7X ROM MCUs are available now in 28-pin DIP, SOIC, SSOP, or QFN packages, 40-pin PDIP and PLCCs, and a 44-pin QFP. MICROCHIP TECHNOLOGY INC., Chandler, AZ. (888) 628-6247.
