Z8523008VEG

Specialized Overview

The Z8523008VEG is an Enhanced Serial Communications Controller (ESCC) manufactured by Zilog. It operates on a 4.5V to 5.5V supply voltage and supports a maximum clock frequency of 8 MHz. The device features two independent serial channels with integrated FIFO buffers, including a 4-byte transmit buffer and an 8-byte receive buffer. It utilizes a 44-pin PLCC package for surface mount installation. The component supports multiple communication protocols such as SDLC, HDLC, and asynchronous modes.

Specialized Feature Summary

• Supports ESCC data communications capabilities with enhanced FIFO structures
• Provides vectored interrupt handling with software acknowledge capability
• Integrates Digital Phase-Locked Loop (DPLL) for clock synchronization
• Includes CRC generation and checking functions for SDLC mode

Specialized Applications

• Network controller implementations requiring serial interface control
• Modem control systems utilizing modem I/O lines
• General-purpose I/O expansion in embedded microprocessor systems

Specialized Procurement Notes

Verify the specific suffix VEG against official Zilog documentation to confirm temperature range and packaging details. Confirm RoHS compliance status as indicated in distributor listings. Check for end-of-life status and availability of replacement components from authorized distributors before procurement.

Specialized Selection Notes

Select this component when a dual-channel serial interface with hardware FIFO support is required. Ensure the system bus timing matches the Z85230/L interface specifications. Verify that the 44-PLCC package fits the target PCB layout constraints. Consider the 8 MHz operational limit when designing the master clock circuitry.

Specialized Part Context

This part belongs to the Z85230 family of Enhanced Serial Communications Controllers. It serves as a peripheral for microprocessors, offering advanced serial data handling compared to earlier SCC models. The VEG suffix typically denotes specific environmental or packaging variations within the standard 5V Z85230 product line.

Specialized Replacement Considerations

Z8523016VEC is a compatible variant within the same family offering similar functionality.
