Z8937120ASG

Overview

The Z8937120ASG is a digital signal processor from the Zilog Z8937120 series. It features a 16-bit data bus and operates at a maximum clock frequency of 20 MHz. The device includes 8 kB of program memory (OTP) and 1 kB of data RAM. It functions on a 5 V supply voltage within an operating temperature range of 0°C to +70°C. The component is classified as a fixed-point DSP.

Feature Summary

• Maximum clock frequency of 20 MHz
• 8 kB OTP program memory size
• 1 kB data RAM size
• 16-bit data bus width

Applications

• Digital signal processing tasks requiring fixed-point arithmetic
• Embedded controller applications within the Z893x1 family scope
• Industrial control systems operating in commercial temperature ranges

Procurement Notes

Verify RoHS compliance status through official manufacturer documentation, as distributor listings indicate detailed requirements. Confirm moisture sensitivity level (MSL 3) handling procedures during assembly. Check for current production status and obsolescence notices directly with Zilog or authorized distributors before procurement planning.

Selection Notes

Select this model when a 20 MHz fixed-point DSP with 8 kB OTP and 1 kB RAM is required. Ensure the design supports 5 V logic levels and 16-bit data buses. Compare against other Z8937120 variants if different package types such as PLCC-44 or QFP are needed instead of the specific configuration offered by this part number.

Part Context

This component belongs to the Z8937120 series of embedded processors and controllers. It shares core specifications like memory size and clock speed with siblings such as the Z8937120VSG and Z8937120PSG, differing primarily in package type and pinout configuration. The series targets general-purpose digital signal processing applications.

Replacement Considerations

Direct substitutes include Z8937120VSG (PLCC-44) and Z8937120PSG (PDIP-40). Verify pin compatibility and package dimensions before substitution. Other Z8937120 family members may serve as alternatives if interface differences are accommodated.
