Application Specific Microcontrollers Procurement Notes

Verify component status as this specific part number may be discontinued or have limited availability. Confirm package type (WFBGA-144) and voltage requirements against system design. Check for updated datasheet revisions to ensure compatibility with current platform specifications.

Application Specific Microcontrollers Selection Notes

Select based on required SRAM size (256KB vs 320KB vs 480KB options in the family) and interface needs (LPC/eSPI). Ensure GPIO count (123) meets system connectivity requirements. Verify thermal performance within the 0°C to +70°C operating range.

Application Specific Microcontrollers Part Context

Part of the MEC170x family of keyboard and embedded controllers. Shares common core architecture with variants like MEC1701Q-C1-TN (169-pin) and MEC1701H-C1-SZ (non-tray packaging). Differentiated by package size and internal memory configuration.

Application Specific Microcontrollers Replacement Considerations

Consider MEC1701Q-C1-TN for larger packages or different pin counts. Verify functional equivalence with MEC1701H-C1-SZ if tray packaging is acceptable instead of tape-and-reel.
