PD78P4916
16-BIT SINGLE-CHIP MICROCONTROLLER
The
µ
PD78P4916 is one of the
µ
PD784915 subseries in the 78K/IV Series microcontrollers which incorporate
a high-speed and high-performance 16-bit CPU.
The
µ
PD78P4916 replaces mask ROM with one-time PROM and increases on-chip ROM and RAM capacity
compared to the
µ
PD784915.
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.
µ
PD784915 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.
