RL78 CPU core CISC architecture with 3-stage pipeline Minimum instruction execution time: Can be changed
from high speed (0.
04167 s: @ 24 MHz operation with high-speed on-chip oscillator) to ultra-low speed (1 s: @ 1 MHz operation) Address space: 1 MB General-purpose registers: (8-bit register x 8) x 4 banks On-chip RAM: 256 B to 2 KB
Code flash memory Code flash memory: 2 to 16 KB Block size: 1 KB Prohibition of block erase and rewriting (security
function) On-chip debug function
Self-programming (with flash shield window function)
Data flash memory Note Data flash memory: 2 KB Back ground operation (BGO): Instructions are
executed from the program memory while rewriting the data flash memory.
