The PSD813F1VA-20UI is a programmable peripheral IC manufactured by STMicroelectronics, designed for 8-bit microcontroller applications. It features a 64-LQFP surface-mount package with dimensions of 14x14 mm. The device operates as a specialized interface component to expand system capabilities. Electrical parameters and specific functional configurations are not detailed in the provided source material.
Verify the exact ordering suffix 'VA-20UI' against official STMicroelectronics documentation to confirm voltage ratings and temperature ranges. Ensure the 64-LQFP package type matches the target PCB footprint requirements before procurement.
Select this component when interfacing 8-bit microcontrollers requiring additional programmable I/O or memory expansion. Confirm that the 64-pin LQFP form factor fits the available board space and that the operating conditions align with the system environment.
This part belongs to the PSD family of programmable peripherals from STMicroelectronics. These components typically serve to extend the address space and I/O capabilities of standard 8-bit microcontrollers in embedded systems.
Check for pin-compatible alternatives within the same PSD series. Verify that any substitute maintains the 64-LQFP package and supports the required 8-bit MCU interface protocols.
