PSD813F2VA-20JI

Overview

The PSD813F2VA-20JI 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 designs. The device operates at a maximum frequency of 20 MHz and supports a supply voltage range of 3.0 V to 3.6 V, with a nominal rating of 3.3 V. It is housed in a 52-pin PLCC package with J-leads, suitable for surface mount applications.

Feature Summary

• Integrates 1 Mbit primary Flash memory and 256 Kbit secondary Flash OPT memory with concurrent read/write/erase capabilities.
• Includes 16 Kbit battery-backed SRAM and over 3000 gates of PLD logic with 16 output macrocells.
• Features 27 individually configurable I/O ports supporting MCU, PLD, and address latch functions.
• Supports In-System Programming (ISP) via a built-in JTAG compliant serial port.

Applications

• Peripheral integration for 8-bit microcontroller systems
• Replacing discrete address latches, decoders, and EPROMs
• In-system programming and configuration of FPGA devices

Procurement Notes

Verify the specific ordering suffix 'VA' against official STMicroelectronics documentation to confirm pinout compatibility and functional equivalence with standard PSD813F2 variants. Ensure the 52-PLCC package matches the target PCB footprint. Confirm industrial temperature range requirements align with the -40°C to +85°C specification found in related PSD813F2 datasheets.

Selection Notes

Select this component when designing 8-bit MCU systems requiring integrated non-volatile memory and programmable logic. It is suitable for applications needing up to 1 Mbit of Flash and 256 Kbit of secondary memory. The 52-pin PLCC package is appropriate for designs utilizing J-lead surface mount technology. Consider the 20 MHz speed grade if higher performance than the 15 MHz variant is required.

Part Context

This part belongs to the PSD813 family of Programmable System Devices, which consolidate multiple peripheral functions into a single IC. The PSD813F2 variant specifically offers 1 Mbit of primary Flash memory. The '20' designation indicates a 20 MHz operating speed, while 'J' typically refers to the plastic leaded chip carrier package type.

Replacement Considerations

Direct replacements include other PSD813F2 variants such as PSD813F2-20U1T or PSD813F4A-20J, provided the package type (PLCC vs QFP) and voltage levels are compatible. Verify that the replacement device supports the same 3.3 V operation and ISP functionality.
