MOS INTEGRATED CIRCUIT
µPD78CP18(A)
8-BIT SINGLE-CHIP MICROCOMPUTER
DESCRIPTION
The µPD78CP18(A) is a version of the µPD78C18(A) in which the internal mask ROM is replaced by one-time PROM.
The one-time PROM version can be programmed once only by users, and is ideally suited for small-scall of many
differnt products, and rapid development and time-to-market of a new product.
The detailed functions are descrived in the following user's manual. Read this manual before starting design
work.
