General Description
The Z80S188 ZiLOG Enhanced Intelligent Peripheral
Controller is a highly integrated 8-bit CMOS micropro-
cessor that includes SIO, CTC, CGC, WDT, and PIO func-
tions, plus 4 KB of ROM with ROM protect, and 1 KB of
RAM with RAM protect in a single 160-pin QFP package.
Security options can protect sensitive code and data in
internal RAM and ROM. This intelligent peripheral
controller is well-suited for a broad range of applications
ranging from error-correcting modems to enhance-
ment/cost reductions of existing hardware using Z80-based
discrete peripherals.
