Z8937120FSC

Overview

The Z8937120FSC is a fixed-point digital signal processor (DSP) from the Z893x1 series, manufactured by Zilog. It features a maximum clock rate of 20 MHz and integrates 8 kB of one-time programmable (OTP) non-volatile memory for program storage alongside 1 kB of on-chip RAM. The device operates at a core and I/O voltage of 5.00 V and supports surface-mount installation in a 44-LQFP package. It functions within an ambient temperature range of 0°C to +70°C.

Feature Summary

• Fixed-point DSP architecture with 20 MHz maximum clock frequency
• Integrated 8 kB OTP program memory and 1 kB data RAM
• 5.00 V operating voltage for both core and I/O interfaces
• Surface-mount 44-LQFP package suitable for automated assembly

Applications

• Embedded digital signal processing tasks requiring fixed-point arithmetic
• Industrial control systems operating within commercial temperature ranges
• Audio or vibration analysis applications utilizing onboard memory constraints

Procurement Notes

Verify component status as the Z8937120FSC is listed as obsolete or discontinued by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers. Ensure compliance with RoHS requirements and check moisture sensitivity level (MSL 3) handling procedures during storage and reflow soldering processes.

Selection Notes

Select this component when a 5V fixed-point DSP with integrated OTP memory is required. Compare against other Z893x1 variants if different packaging options like PLCC-44 or PDIP-40 are needed. Verify that the 20 MHz speed and 16-bit data bus width meet the specific throughput requirements of the target application.

Part Context

This part belongs to the Z89371 family of embedded processors and controllers. It shares architectural similarities with variants such as the Z8937120ASG, Z8937120VSG, and Z8937120PSG, differing primarily in package type and manufacturing suffix. The FSC suffix specifically denotes the 44-LQFP surface-mount configuration.

Replacement Considerations

Direct pin-compatible replacements may include other Z89371xx variants with different packages. For functional equivalents, evaluate other 20 MHz fixed-point DSPs with similar memory configurations. Check for updated lifecycle notices from Zilog or Microchip Technology regarding end-of-life support.
