Z8937120PSG

Overview

The Z8937120PSG is a fixed-point digital signal processor (DSP) from the Zilog Z893x1 series. It features an 8 kB OTP program memory and 1 kB data RAM, operating at a maximum clock frequency of 20 MHz with a 16-bit data bus width. The device requires a 5 V supply voltage and supports through-hole installation in a PDIP-40 package. It functions within an ambient temperature range of 0°C to +70°C.

Feature Summary

• Integrated 8 kB OTP program memory and 1 kB data RAM
• 20 MHz maximum clock frequency with 16-bit data bus
• PDIP-40 through-hole package for standard PCB mounting

Applications

• Embedded digital signal processing tasks
• Fixed-point arithmetic control systems
• Industrial automation controllers

Procurement Notes

Verify component authenticity against Zilog specifications. Confirm RoHS compliance status via official documentation. Check manufacturing date codes for age-related reliability. Ensure storage conditions respect humidity sensitivity levels prior to assembly.

Selection Notes

Select this model when a 16-bit DSP architecture with OTP programming is required. The PDIP-40 package suits prototyping or low-volume through-hole designs. Verify that the 20 MHz speed and 5 V logic levels match system constraints.

Part Context

This part belongs to the Z8937120 family, which includes variants like the ASG and VSG differing primarily in packaging. The PSG suffix specifically denotes the PDIP-40 through-hole configuration, distinguishing it from surface-mount options like PLCC or QFP.

Replacement Considerations

Direct pin-compatible replacements include other Z8937120 variants such as Z8937120ASG or Z8937120VSG if package adaptation is feasible. Cross-vendor substitutes require architectural verification.
