DATA SHEET
MOS INTEGRATED CIRCUIT
µPD78P4916
16-BIT SINGLE-CHIP MICROCONTROLLER
The µPD78P4916 is one of the µPD784915 subseries in the 78K/IV Series microcontrollers which incorporate a high-speed and high-performance 16-bit CPU. The µPD78P4916 replaces mask ROM with one-time PROM and increases on-chip ROM and RAM capacity compared to the µPD784915. It is suitable for evaluation at system development and for small quantity production. D e t a i l e d descriptions of functions are provided in the following user's manuals. Be sure to read these d o c u m e n t s when designing.
µPD784915 Subseries User's Manual Hardware : U10444E
78K/IV Series User's Manual Instruction : U10905E
FEATURES
High-speed instruction execution using 16-bit CPU core · Minimum instruction execution time: 250 ns (at 8-MHz internal clock) On-chip high capacity memory · PROM : 62 Kbytes Note · RAM Note : 2048 bytes Note
It is possible to change the capacity of the internal PROM and the internal RAM by specifying the internal memory capacity select (IMS) register.
