The PSD853F2-90MI is a programmable peripheral integrated circuit manufactured by STMicroelectronics. It is housed in a 52-pin Plastic Quad Flat Package (PQFP) with dimensions of 10x10 mm. Designed for surface-mount technology, this component functions as an 8-bit MCU peripheral. The device allows for customizable logic and interface configurations to support specific microcontroller applications.
Verify the specific revision level and manufacturing date code upon receipt. Confirm that the 52-PQFP footprint matches the target PCB design. Ensure static-sensitive handling procedures are followed during installation.
Select this component when fixed-function peripherals are insufficient for an 8-bit MCU design. The programmable nature allows for tailoring interface requirements without changing the main processor. Evaluate pin count and I/O flexibility against system constraints.
This part belongs to the category of specialized ICs within the STMicroelectronics portfolio. It serves as a supplementary chip to extend the capabilities of 8-bit microcontrollers, providing flexible logic solutions in a compact surface-mount package.
