PSD813F1VA-15J

Overview

The PSD813F1VA-15J is a Flash in-system programmable (ISP) peripheral IC manufactured by STMicroelectronics, designed for 8-bit microcontrollers. It integrates dual-bank Flash memory, SRAM, and a Programmable Logic Device (PLD). The device features up to 2 Mbit of primary Flash memory and 256 Kbit of secondary Flash, along with 256 Kbit of SRAM. It includes 27 reconfigurable I/O ports and supports concurrent read/erase/write operations. Packaged in a 52-LCC (J-Lead) surface-mount case, it operates at speeds up to 15 MHz.

Feature Summary

• Dual-bank Flash architecture with up to 2 Mbit primary and 256 Kbit secondary memory
• Integrated 256 Kbit SRAM for data storage
• Over 3000 gates of PLD logic with 16 output and 24 input macrocells
• Built-in JTAG-compliant serial port for full-chip in-system programmability

Applications

• Expanding address space for 8-bit MCUs via page register
• Embedded system design requiring flexible I/O configuration
• Applications needing concurrent memory operation and code execution

Procurement Notes

Verify the specific speed grade suffix (e.g., -15J) against the manufacturer's datasheet to confirm the maximum operating frequency. Ensure the 52-LCC package dimensions match the target PCB footprint. Confirm RoHS compliance status if required by the final assembly specifications.

Selection Notes

Select this component when an 8-bit MCU requires additional non-volatile memory and logic resources without increasing pin count. The dual-bank Flash allows for background updates while executing code from the other bank. Verify that the 256 Kbit SRAM capacity meets the runtime data requirements of the application.

Part Context

This part belongs to the PSD813F family of Flash ISP peripherals. Variants within the series differ primarily in speed grades (indicated by suffixes like -90, -15) and package types (such as TQFP or PLCC). The base functionality remains consistent across the family, providing integrated memory and PLD resources for embedded control systems.

Replacement Considerations

Direct replacements must maintain the 52-pin LCC package and compatible voltage levels. Check alternative parts for identical Flash/SRAM capacities and PLD gate counts. Ensure the replacement supports JTAG ISP programming if in-system updates are required.
