General Description
ZiLOG’s Z84C90 Serial/Parallel/Counter/Timer KIO is a multi-channel, multipurpose I/O
device designed to provide the end-user with a cost-effective and powerful solution to
meet peripheral needs. The Z84C90 combines the features of one Z84C30 CTC, one
Z84C20 PIO, a Z84C4x SIO, a 8-bit, bit-programmable I/O port, and a crystal-oscillator
into a single package (84-pin PLCC or 100-pin LQFP). Using fifteen internal registers for
data and programming information, the KIO can easily be configured to any given system
environment. Although the optimum performance is obtained with a Z84C00 CPU, the
KIO can just as easily be used with any other CPU.
