Microcontrollers Procurement Notes

This component is officially listed as discontinued by the manufacturer. Verify availability through authorized distributors or secondary markets. Confirm silicon revision and datasheet version before integration. Ensure design-in compatibility with existing firmware and hardware constraints due to end-of-life status.

Microcontrollers Selection Notes

Select this part for legacy system maintenance or cost-sensitive designs where the specific pinout and peripheral set are required. Evaluate alternative Microchip devices if long-term supply assurance is critical. Consider the trade-off between the established ecosystem and potential obsolescence risks associated with discontinued components.

Microcontrollers Part Context

The PIC16F877T-04I/L belongs to the PIC16F87X series, which includes the PIC16F873, PIC16F874, and PIC16F876. These devices share a common architecture but differ in memory sizes and package options. The PIC16F877 specifically provides the maximum memory capacity within the 28/40-pin enhanced flash microcontroller lineup.

Microcontrollers Replacement Considerations
