Z8673312VSC

Microcontrollers Overview

The Z8673312VSC is an 8-bit microcontroller from the Zilog Z8 family, featuring a Z8 core and 8 kB of One-Time Programmable (OTP) ROM. It provides 24 I/O lines and supports clock speeds up to 12 MHz. The device operates within a voltage range of 3.5 V to 5.5 V and includes two programmable 8-bit counter/timers with 6-bit prescalers. It offers six vectored interrupts, software-programmable low EMI mode, and two comparators.

Microcontrollers Feature Summary

• Features a Z8 core with fast instruction pointer execution and multiple address spaces for system expansion.
• Includes programmable Watchdog Timer, Auto Power-On Reset, and two standby modes (STOP and HALT).
• Supports versatile clocking via on-chip oscillator accepting crystal, ceramic resonator, or external clock drive.
• Provides configurable push-pull/open-drain outputs on Ports 0, 1, and 2 with digital CMOS Schmitt-triggered inputs.

Microcontrollers Applications

• General-purpose embedded control systems requiring OTP memory.
• Industrial applications utilizing programmable timers and interrupt handling.
• Low-power consumer electronics employing STOP and HALT standby modes.
• Systems requiring software-programmable low EMI operation.

Microcontrollers Procurement Notes

Verify the specific suffix 'VSC' against official Zilog documentation to confirm package type and temperature grade. Confirm availability status as this component may be subject to discontinuation notices. Ensure compatibility with existing EPROM programming hardware if reprogramming is required.

Microcontrollers Selection Notes

Select this part for designs needing 8 kB OTP storage and 24 I/O lines in a compact form factor. Consider the Z86E33 variant for lower memory requirements or the Z86E43 series for increased I/O capacity. Verify that the 3.5 V to 5.5 V operating range aligns with the target power supply constraints.

Microcontrollers Part Context

This microcontroller belongs to the Z86E33/733/E34 series within the Zilog Z8 MCU family. It shares architectural similarities with the Z86E43/743/E44 variants but differs in pin count and I/O configuration. The device is designed for cost-effective single-chip solutions using standard CMOS processes.

Microcontrollers Replacement Considerations

Direct substitutes are not explicitly listed in the provided datasheet. Evaluate other members of the Z86E33/733 family based on memory size and I/O requirements. Cross-reference with Z8 Encore! series for modern alternatives if OTP constraints allow.
