Z8023010PSG

Specialized Overview

The Z8023010PSG is an Enhanced Serial Communications Controller (ESCC) manufactured by Zilog, designed for high-performance serial data communications. It features a 40-pin Dual In-line Package (PDIP) with a width of 0.620 inches (15.75 mm). The device operates on a single 5V supply voltage within the range of 4.5V to 5.5V. It implements a Z80-compatible multiplexed address/data bus interface and includes two independent serial channels. Key internal specifications include a 4-byte transmit FIFO buffer and an 8-byte receive FIFO buffer to optimize data throughput.

Specialized Feature Summary

• Supports ESCC protocol enhancements including SDLC CRC reception and improved interrupt handling mechanisms
• Integrates dual-channel architecture with dedicated FIFO buffers for efficient data management
• Provides flexible clocking options via Digital Phase-Locked Loop (DPLL) and baud rate generator

Specialized Applications

• Data communications systems requiring multi-protocol serial support
• Microprocessor peripheral interfaces utilizing Z80 bus architectures
• Embedded control applications needing DMA and vectored interrupt capabilities

Specialized Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment against the 40-PDIP specification. Check for RoHS compliance documentation as required by project standards. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly.

Specialized Selection Notes

Select this component when a Z80-bus compatible serial controller with enhanced FIFO capabilities is required. Compare against the Z85230 variant if a non-multiplexed bus interface is preferred. Evaluate system timing constraints against the specified AC characteristics. Consider the PDIP package availability relative to surface-mount alternatives in the same family.

Specialized Part Context

This part belongs to the Z80230/Z85230/L Enhanced Serial Communications Controller family. It serves as a specialized interface IC bridging microprocessors and serial communication lines. The Z80230 variant specifically targets systems utilizing the Z80 CPU bus structure, distinguishing it from the Z85230 which supports standard synchronous buses.
