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.
Detailed descriptions of functions are provided in the following user's manuals. Be sure to read these
documents 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 : 2048 bytes ^Note
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.
