ROMless μCs ensure hassle-free upgrades without hardware changes

摘要

In high-end embedded systems applications, you don't want to be caught short of memory while using an 8-bit μC. Also, increased use of higher-level programming languages, combined with RTOSs, has been driving memory requirements to megabyte sizes. Invariably user-friendly feature upgrades require extra sub-menus, which in turn demand more memory. Enter Microchip's PIC18C602 and P'lCl8C801 ROMless μCs. The two μCs offer you the flexibility to add external flash or EPROM program memory to expand and fit the program/data memory to the application in high-end systems.
