PSD913F2-90JI is an integrated programmable system device from STMicroelectronics, packaged in 52-PLCC, designed as an in-system programmable peripheral companion chip for 8-bit microcontrollers, integrating dual-bank flash, SRAM, over 3000-gate PLD and 27 reconfigurable I/O pins to simplify external logic and memory expansion for legacy embedded hardware.
- Dual independent flash banks support read-while-write operation to enable safe field firmware upgrade without system halt;
- Built-in DPLD and GPLD blocks handle address decoding, chip selection and custom glue logic to reduce discrete logic chips on PCB;
- JTAG ISP interface supports in-circuit programming and debugging without removing the chip from the circuit board;
- Wide configurable I/O functions, including open-drain mode, address latch output and general digital I/O for flexible system connection.

This PSD chip fits industrial controllers, serial communication modules, smart meter mainboards, and old 8-bit MCU upgrade projects, offering compact glue logic and non-volatile memory expansion for stable embedded control designs.
Alternative PSD chip models
PSD913F2A-90JI is a pin-compatible variant with identical memory and PLD resources for direct drop-in replacement. PSD813F2A-90JI is a smaller-density PSD device suitable for cost-sensitive projects with lower memory demand. PSD933F2-90JI provides larger flash capacity for firmware that requires more storage space.
IC Sourcing note: Confirm original marking and package form; this part is an end-of-life legacy IC, check batch traceability and avoid refurbished inventory, and confirm lead time before placing bulk orders.
