PSD834F2-90M

Overview

The PSD834F2-90M is a programmable peripheral integrated circuit manufactured by STMicroelectronics. Designed for 8-bit microcontroller applications, this device provides configurable logic functions to extend system capabilities. It operates with a guaranteed propagation delay of 90 nanoseconds, ensuring timely signal processing in digital circuits. The component is housed in a 52-pin Plastic Quad Flat Package (PQFP) with dimensions of 10x10 mm, suitable for surface mount technology. This IC serves as a versatile interface solution for embedded systems requiring custom logic integration.

Feature Summary

• Programmable logic architecture for customized peripheral functions
• Guaranteed 90 ns propagation delay for high-speed operation
• 52-pin PQFP package (10x10 mm) for surface mount installation
• Compatible with 8-bit microcontroller platforms

Applications

• 8-Bit MCU Peripherals
• Embedded system logic expansion
• Custom digital interface design

Procurement Notes

Verify the specific revision level and manufacturing date code upon order confirmation. Confirm that the 52-PQFP package matches the target PCB footprint exactly. Ensure static-sensitive handling procedures are followed during storage and assembly. Check for any specific environmental compliance documentation required for the destination market.

Selection Notes

Select this component when fixed-function logic gates are insufficient for the application requirements. The 90 ns speed rating suits standard digital control loops. Consider the 52-pin count against available board space. Verify voltage compatibility with the host 8-bit MCU I/O levels before finalizing the design.

Part Context

This part belongs to the family of complex programmable logic devices (CPLDs) or similar programmable peripherals offered by STMicroelectronics. These components bridge the gap between discrete logic chips and general-purpose microcontrollers, allowing designers to implement specific timing or decoding logic without additional firmware overhead.

Replacement Considerations

Direct pin-to-pin replacements must match the 52-PQFP form factor and 90 ns performance specification. Verify logical equivalence through updated datasheets from alternative manufacturers. Ensure programming tools and configuration files are compatible with the substitute device.
