PSD854F2V-12MI

Overview

The PSD854F2V-12MI is a programmable peripheral IC from STMicroelectronics, designed as Flash in-system programmable (ISP) peripherals for 8-bit MCUs. It features 24 macrocells and utilizes FLASH memory type. The component is housed in a 52-PQFP package with dimensions of 10x10 mm. It operates within a temperature range of -40°C to 85°C.

Feature Summary

• Supports in-system programming via Flash technology
• Integrates programmable logic with 24 macrocells
• Designed specifically for 8-bit microcontroller applications

Applications

• Peripheral expansion for 8-bit MCUs
• Logic implementation in embedded systems
• Custom interface generation for microcontrollers

Procurement Notes

Verify the specific suffix '12MI' against official STMicroelectronics documentation to confirm pinout and electrical characteristics. Ensure compatibility with the target 8-bit MCU architecture before integration. Check for discontinued status or lifecycle notices on official channels.

Selection Notes

Select this component when integrating programmable logic directly with 8-bit microcontrollers requiring ISP capabilities. Consider the 52-pin PQFP package constraints and the 24 macrocell limit for complex designs. Verify operating temperature requirements against the -40°C to 85°C specification.

Part Context

This part belongs to the PSD854F2V series, which provides Flash-based programmable peripherals. It serves as a bridge between fixed-function microcontrollers and flexible I/O or logic requirements, eliminating the need for separate GALs or PLDs in many 8-bit MCU designs.

Replacement Considerations

Consult official STMicroelectronics substitution guides for direct equivalents. Generic FPGA replacements may not offer compatible ISP interfaces or pinouts for 8-bit MCU integration without significant redesign.
