Application Specific Microcontrollers Procurement Notes

Verify the specific speed grade and voltage variant corresponding to the EH suffix against the official datasheet parametric characteristics. Confirm package availability and lead times directly with NXP Semiconductors or authorized distributors, as this is a preliminary specification document that may supersede earlier versions.

Application Specific Microcontrollers Selection Notes

Select based on required processing throughput and power constraints. The series offers optional lower-voltage CPUs for power-constrained designs. Ensure compatibility with existing memory systems, supporting SDRAM sizes up to 256 Mbit. Verify pin compatibility if replacing TM-1300 predecessors.

Application Specific Microcontrollers Part Context

The PNX1300 Series represents an enhanced version of the TM-1300 family, maintaining 100% pin compatibility while offering faster clock speeds and improved main memory interfaces. It continues the tradition of high-performance, low-cost media processors developed by Philips Semiconductors.

Application Specific Microcontrollers Replacement Considerations

PNX1300EH/G and PNX1311EH/G are part of the same series. Check specific clock speed and peripheral configurations before substitution.
