• Integrates Flash ISP peripherals for 8-bit MCUs
• Supports up to 90 MHz operation speed
• Housed in a 52-PQFP (10x10) surface-mount package

Applications

• 8-Bit MCU Peripherals

Procurement Notes

Verify the specific suffix 'A-90M' against official STMicroelectronics documentation to confirm voltage levels and temperature ranges. Ensure the 52-PQFP package matches the target PCB footprint. Confirm RoHS compliance status through the manufacturer's current datasheet rather than relying on general category assumptions.

Selection Notes

Select this component when designing 8-bit MCU systems requiring integrated memory and logic to reduce board space. The 90 MHz speed rating suits high-performance applications. Verify that the 52-pin interface aligns with the microcontroller's pinout requirements before finalizing the design.

Part Context

This part belongs to the PSD813 family of Programmable System Devices from STMicroelectronics. These devices are engineered to replace multiple discrete components such as EPROMs, RAMs, and PLDs. The series allows for simplified hardware design and improved system reliability by integrating these functions into one chip.

Replacement Considerations

Check for compatible parts within the PSD813 series. Verify pin compatibility and electrical specifications against the original design requirements before substitution.
