PSD833F2-90M

Overview

The PSD833F2-90M is a programmable peripheral integrated circuit manufactured by STMicroelectronics. It is designed as an auxiliary component for 8-bit microcontroller systems, providing additional functionality to enhance system capabilities. The device is housed in a 52-pin Plastic Quad Flat Package (PQFP) with dimensions of 10x10 mm. It supports surface mount technology for automated assembly processes. This component serves as a specialized interface or extension unit within embedded control architectures.

Feature Summary

• Programmable peripheral IC architecture for 8-bit MCU expansion
• 52-pin PQFP package (10x10 mm) for surface mount installation
• Designed specifically for integration with 8-bit microcontroller platforms

Applications

• Peripheral expansion for 8-bit microcontroller systems
• Embedded control applications requiring additional I/O or logic functions
• Industrial automation modules utilizing 8-bit processing cores

Procurement Notes

Verify the specific revision level and manufacturing date code upon order confirmation. Confirm that the 52-PQFP (10x10) package dimensions align with the target PCB footprint. Ensure compatibility with existing 8-bit MCU signal levels and timing requirements before finalizing procurement specifications.

Selection Notes

Select this component when an 8-bit MCU requires additional programmable peripheral functions not available on-chip. The 52-pin form factor dictates board space allocation. Verify that the host system's voltage levels match the IC's operational requirements. Consider thermal dissipation characteristics associated with the PQFP package during layout design.

Part Context

This part belongs to the category of specialized programmable peripherals rather than standalone processors. It complements STMicroelectronics' 8-bit MCU portfolio by offloading specific tasks or expanding connectivity options. It is distinct from general-purpose logic chips due to its programmability tailored for microcontroller environments.

Replacement Considerations

No publicly confirmed direct substitute part numbers are available in the provided documentation. Evaluate pin-compatible alternatives only if they explicitly support the same 8-bit MCU peripheral protocol and 52-PQFP mechanical constraints.
