STMPE1600QTR

Overview

The STMPE1600QTR is a 16-bit I/O expander featuring ultra-low power consumption, designed for interface expansion in embedded systems. It operates within an industrial temperature range of -40°C to +85°C and supports surface-mount installation in a 24-pin QFN package. The component provides general-purpose parallel I/O ports with configurable direction settings, enabling flexible connectivity for peripheral devices while minimizing system power usage.

Feature Summary

• Ultra-low power consumption architecture for energy-efficient operation
• Configurable 16-bit parallel I/O port expansion capability
• Industrial-grade temperature rating for robust environmental performance

Applications

• Embedded system peripheral interface expansion
• General-purpose digital input/output control
• Low-power consumer electronics design

Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or certified partners. Confirm lifecycle status as NRND (Not Recommended for New Designs) prior to integration. Ensure compatibility with existing PCB footprints and thermal management requirements. Validate datasheet specifications against current revision documents to avoid obsolescence risks during production scaling.

Selection Notes

Select this component when 16-bit parallel I/O expansion is required with minimal power overhead. Consider the 24-pin QFN package constraints for layout density. Evaluate alternative models if active procurement support is critical, given its non-recommended status. Assess thermal dissipation needs relative to the specified industrial temperature range.

Part Context

Part of the STMPE series of I/O expanders from STMicroelectronics, focusing on low-power applications. Shares functional similarities with other members like the STMPE801 but differs in pin count and capacity. Designed for compact designs requiring reliable digital interface extension without significant power penalty.

Replacement Considerations

No public confirmed substitute part numbers are available. The STMPE801QTR offers similar functionality but utilizes a different QFN-16L footprint instead of QFN-24. Designers should evaluate mechanical and electrical compatibility carefully if considering alternatives due to the obsolete status.
