MEC1641-PZV-CEL00-TR

Application Specific Microcontrollers Overview

The MEC1641-PZV-CEL00-TR is an Embedded Controller within the MEC164x family, utilizing a 32-bit ARC 625D core. It features 288KB embedded flash, 16KB SRAM, and 2KB EEPROM. The device operates at a maximum frequency of 20MHz across a commercial temperature range of 0°C to +70°C. It integrates 108 GPIOs, six SMBus ports, sixteen ADC channels, and two low-power timers. Communication with the host system is achieved via the Intel Low Pin Count (LPC) bus, while split-architecture management utilizes the BC-Link protocol.

Application Specific Microcontrollers Feature Summary

• ARC 625D 32-bit microcontroller core with 288KB Flash and 16KB SRAM
• Intel LPC host interface combined with BC-Link for companion component access
• Integrated power management sensing for VBAT, VTR, and VCC planes
• Peripheral set includes 108 GPIOs, 6 SMBus ports, 16-channel ADC, and 2 PWM outputs

Application Specific Microcontrollers Applications

• System Embedded Controllers requiring instant-on capabilities
• Split-architecture I/O controller designs using BC-Link protocols
• Power management units monitoring multiple voltage rails

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix CEL00 against official Microchip documentation to confirm packaging and reel specifications. Ensure compatibility with existing firmware architectures designed for the ARC 625D core before procurement. Confirm that the 0°C to +70°C operating range meets the target application's environmental requirements.

Application Specific Microcontrollers Selection Notes

Select this component when a dedicated Embedded Controller is required alongside a companion I/O chip. The MEC1641 supports split-architecture designs via BC-Link. Verify that the 20MHz clock speed and memory sizes are sufficient for the intended ACPI and power management logic.

Application Specific Microcontrollers Part Context

This part belongs to the MEC164x series of advanced I/O controllers. It serves as the base component in a split-architecture system, distinct from single-chip MCUs by relying on BC-Link communication with companion devices for expanded I/O handling.

Application Specific Microcontrollers Replacement Considerations

Direct replacements include other MEC1641 variants such as MEC1641-PZV or MEC1641-PZV-TR. Cross-family migration requires re-evaluation of the BC-Link protocol implementation and pinout compatibility.
