The Z84C2006PEG is a Parallel Input/Output direct interface between Z80 MCU and peripherals. It has 16 I/O and 40 pin count. The Z80 PIO Parallel I/O circuit is a programmable, dual-port device that provides a TIL-compatible interface between peripheral devices. The CPU configures the Z80 PIO to interface with a wide range of peripheral devices that are compatible with the Z80 PIO include most keyboards, paper tape readers and punches, printers and PROM programmers. One characteristic of the Z80 peripheral controllers that separates them from other interface controllers is that all data transfer between the peripheral device and the CPU is accomplished under the interrupt control.
● For Z80 CPU systems
● PIO communications controller
● Provides a direct interface between Z80 microcomputer systems and peripheral devices
● Two ports with interrupt-driven handshake for fast response
● Four programmable operating modes, output, input, bidirectional (Port A only) and bit control
● Programmable interrupts on peripheral status conditions (1.5mV at 1.5V)
● NMOS version for cost sensitive performance solutions
● CMOS version for the designs requiring high speed and low power consumption
