PSD813F2VA-15M

Overview

The PSD813F2VA-15M is a Flash In-System Programmable (ISP) peripheral for 8-bit microcontrollers, manufactured by STMicroelectronics. It features dual-bank Flash memory with up to 2 Mbit primary and 256 Kbit secondary capacity, supporting concurrent read/erase/write operations. The device includes up to 256 Kbit of battery-backed SRAM and 27 reconfigurable I/O ports. It integrates an enhanced JTAG serial port for full-chip in-system programmability and a PLD with over 3000 gates, including 16 output and 24 input macrocells. The component operates at 5V and is housed in a 52-PQFP package.

Feature Summary

• Dual-bank Flash memory architecture allowing concurrent operation between primary and secondary banks
• Integrated PLD with over 3000 gates, configurable as CPLD or DPLD
• Built-in JTAG compliant serial port for efficient in-system programming and testing
• 27 individually configurable I/O ports supporting multiple functions including MCU and PLD I/Os

Applications

• Flash In-System Programmable (ISP) peripherals for 8-bit MCUs
• MCU I/O expansion and special function I/Os
• Latched MCU address output generation
• User-defined internal chip select decoding via DPLD configuration

Procurement Notes

Verify the specific ordering suffix against official STMicroelectronics documentation to confirm package type and electrical characteristics. Ensure compatibility with 5V logic levels and JTAG interface requirements for your target 8-bit MCU system design.

Selection Notes

Select this component when requiring integrated Flash memory, SRAM, and programmable logic in a single peripheral for 8-bit microcontroller systems. Consider the 52-pin PQFP package constraints and verify that the available 27 I/O pins meet the system's connectivity needs alongside the PLD gate count requirements.

Part Context

This part belongs to the PSD813F2 family of ISP peripherals from STMicroelectronics. These devices are designed to extend the capabilities of 8-bit MCUs by providing non-volatile memory and programmable logic resources without occupying additional MCU pins or board space.

Replacement Considerations

Check for other variants within the PSD813F2 series or the broader PSD8xxxF2 family for potential pin-compatible alternatives with different memory capacities or package options.
