Z8937120VSC

Overview

The Z8937120VSC is a fixed-point digital signal processor (DSP) from the Zilog Z893x1 series. It features a 16-bit data bus and operates at a maximum clock frequency of 20 MHz. The device integrates 8 kB of OTP program memory and 1 kB of data RAM. It requires a 5 V operating supply voltage and supports surface-mount installation in a PLCC-44 package. The component functions within an ambient temperature range of 0°C to +70°C.

Feature Summary

• 16-bit fixed-point DSP architecture with 20 MHz maximum clock speed
• Integrated 8 kB OTP program memory and 1 kB data RAM
• PLCC-44 surface-mount package for SMD/SMT applications

Applications

• Digital signal processing tasks requiring fixed-point arithmetic
• Embedded controller systems utilizing the Z893x1 family
• Industrial or commercial equipment operating within standard temperature ranges

Procurement Notes

Verify RoHS compliance status, as some sources indicate non-compliance. Confirm moisture sensitivity level (MSL 3) requirements for handling. Check current availability as stock levels may be limited. Ensure the specific suffix 'VSC' corresponds to the intended package and temperature grade before ordering.

Selection Notes

Select this model for designs requiring a 16-bit DSP core with on-chip OTP storage. Compare against variants like Z8937120ASG or Z8937120FSC if different packaging (Tray, QFP) is preferred. Ensure the 5 V logic level matches system interfaces. Verify that the 20 MHz performance meets real-time processing constraints.

Part Context

This component belongs to the Zilog Z893x1 series of embedded processors. It shares core specifications with other suffixes such as Z8937120VSG and Z8937120PSG, differing primarily in package type (PLCC-44 vs. PDIP-40) and shipping configuration. The part is categorized under Digital Signal Processors & Controllers.

Replacement Considerations

Direct substitutes include Z8937120VSG (same PLCC-44 package). Other functional equivalents in the series are Z8937120ASG (Tray) and Z8937120FSC (QFP), though package changes require PCB layout adjustments.
