Zilog Z8

The Zilog Z8 is a microcontroller architecture, originally introduced in 1979, which today also includes the eZ8 Encore!, eZ8 Encore! XP, and eZ8 Encore! MC families.

Signifying features of the architecture are up to 4,096 fast on-chip registers which may be used as accumulators, pointers, or as ordinary RAM. A 16-bit address space for between 1 KB and 64 KB of either OTP ROM or flash memory are used to store code and constants, and there is also a second 16-bit address space which may be used for large applications.
