Z8930112PSC

Overview

The Z8930112PSC is a digital signal processor and controller (DSC) from the Zilog Z893 series, designed for TV and VCR composite video applications. It features an 8-bit data bus width and integrates 24kB of One-Time Programmable (OTP) program memory alongside 640 x 16 words of RAM. The device operates within a supply voltage range of 4.5V to 5.5V and supports up to 26 I/O lines. Packaged in a 52-pin Dual In-line Package (SDIP), it functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Optimized for TV/VCR composite video output processing
• Supports 26 configurable I/O pins with 4.5V to 5.5V supply operation

Applications

• TV controllers
• VCR composite video processing

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is restricted, and standard distribution channels may not stock new units. Verification of authenticity and physical condition is critical when sourcing from secondary markets due to the end-of-life status.

Selection Notes

Select this part only if legacy compatibility with Z893 architecture is required for specific video control logic. Note that the OTP memory type prevents reprogramming after initial fabrication. Ensure the design accommodates the 52-DIP footprint and 5.5V maximum voltage limits.

Part Context

The Z8930112PSC belongs to the Z893xx family of embedded processors specialized for consumer electronics video control. It combines DSP capabilities with microcontroller features to handle real-time video signal processing tasks within television and video cassette recorder systems.

Replacement Considerations

No public confirmed substitute part numbers are available. Due to the obsolete status and specific video application focus, direct pin-to-pin replacements are not documented in public sources.
