PSD813F2VA-20MI

Overview

The PSD813F2VA-20MI is a Programmable System Device (PSD) from STMicroelectronics, designed as an in-system programmable peripheral for 8-bit microcontrollers. It integrates Flash memory, SRAM, and PLD logic into a single chip to simplify embedded system design. The device operates at a maximum frequency of 20 MHz and supports a supply voltage range typical for 3.3V or 5V logic families, though specific voltage ratings are not detailed in the provided local source. It is housed in a 52-pin Plastic Quad Flat Package (PQFP) with a 10x10 mm footprint, suitable for surface-mount assembly.

Feature Summary

• Integrates Flash ISP peripherals for 8-bit MCUs
• Includes reconfigurable I/O ports and PLD macrocells
• Supports In-System Programming via JTAG interface

Applications

• 8-Bit MCU Peripherals
• Embedded control systems requiring integrated memory and logic

Procurement Notes

Verify the exact operating voltage and temperature range against the official datasheet, as the local source does not specify these critical electrical parameters. Confirm that the 52-PQFP package dimensions match your PCB footprint requirements. Ensure compatibility with your target 8-bit MCU architecture before procurement.

Selection Notes

Select this component when designing 8-bit MCU systems that require integrated Flash memory, SRAM, and programmable logic to reduce board space and component count. The 52-PQFP package is suitable for applications where surface-mount technology is preferred but leaded pin accessibility for prototyping or specific thermal management is needed. Compare with other PSD family members if higher memory density or different I/O counts are required.

Part Context

The PSD813F2 series belongs to STMicroelectronics' Programmable System Devices family, which combines microcontroller peripherals with non-volatile memory and programmable logic. This integration aims to replace multiple discrete components such as EPROM, SRAM, and PLDs, thereby simplifying the schematic and improving system reliability in embedded applications.

Replacement Considerations

Check for direct pin-compatible replacements within the PSD813F2 family or newer generations from STMicroelectronics. Verify that any substitute maintains the same 52-PQFP package and supports the required 8-bit MCU interface protocols.
