Product Summary

The Z84C2006VEC is a programmable, dual-port device that provides a TTL-compatible interface between peripheral devices and the Z84C2006VEC CPU (Figures 1 and 2). Note the QFP package is only available in CMOS version. Another feature of the PIO is the ability to interrupt the CPU upon occurrence of specified status conditions in the peripheral device. For example, the PIO can be programmed to interrupt if any specified peripheral alarm conditions should occur. This interrupt capability reduces the time the processor must spend in polling peripheral status. The Z84C2006VEC interfaces to peripherals via two independent general-purpose I/O ports, designated Port A and Port B. Each port has eight data bits and two handshake signals, Ready and Strobe, which control data transfer The Ready output indicates to the peripheral that the port is ready for a data transfer. Strobe is an input from the peripheral that indicates when a data transfer has occurred.

Parametrics

Z84C2006VEC absolute maximum ratings: (1)Voltages on Vqc with respect to Vss: - 0.3V to + 7.0V; (2)Voltages on all inputs with respect to Vgs: - 0.3V to V to + 0.3V; (3)Storage Temperature: -65°C to +150°C.

Features

Z84C2006VEC features: (1)Provides a direct interface between Z80 microcomputer systems and peripheral devices; (2)Two ports with interrupt-driven handshake for fast response; (3)Four programmable operating modes: Output, Input, Bidirectional (Port A only), and Bit Control; (4)Programmable interrupts on peripheral status conditions. (1.5 mV @ 1.5V); (5)NMOS verson for cost sensitive performance solutions; (6)CMOS version for the designs requiring high speed and low power consumption.
