MEC1641-PZV-PBC01-TR

Application Specific Microcontrollers Overview

The MEC1641-PZV-PBC01-TR is a mixed-signal base component of an advanced I/O controller system, featuring a 32-bit ARC 625D embedded microcontroller. It integrates 288 KB of embedded flash, 16 KB of SRAM, and 2 KB of EEPROM. The device communicates via the Intel Low Pin Count (LPC) bus and utilizes the BC-Link protocol to access companion components in a split architecture. It supports 'instant on' functionality through separate VBAT and VTR suspend supplies while sensing the VCC runtime plane. Operating within a commercial temperature range of 0°C to +70°C, it runs at a maximum frequency of 20 MHz.

Application Specific Microcontrollers Feature Summary

• ARC 625D 32-bit core with 288 KB Flash, 16 KB SRAM, and 2 KB EEPROM
• Intel LPC host interface with BC-Link protocol for companion chip communication
• 108 GPIOs, 6 SMBus ports, 16 ADC channels, and 3 LEDs
• Dual suspend power planes (VBAT, VTR) for instant-on capability

Application Specific Microcontrollers Applications

• System power management and instant-on control
• Embedded controller base components in split-architecture systems
• BIOS debug port and port 80 interfaces
• Fan tachometer and PWM control applications

Application Specific Microcontrollers Procurement Notes

Verify the specific PBC01 suffix against official Microchip documentation to confirm package marking or tape-and-reel specifications. Ensure the operating environment remains within the 0°C to +70°C commercial range. Confirm that the 20 MHz clock speed meets system timing requirements before procurement.

Application Specific Microcontrollers Selection Notes

Select this component when a dedicated base controller for an Advanced I/O system is required. The 288 KB flash capacity supports complex firmware logic. Verify compatibility with the intended BC-bus companion chip. The 144 TFBGA package requires appropriate PCB layout considerations for thermal dissipation and signal integrity.

Application Specific Microcontrollers Part Context

This part belongs to the MEC1641 family of multi-device advanced I/O controllers. Other variants include MEC1641-PZV and various trailing suffixes such as -ASP00, -BP200, and -CEL00. These variations typically denote different packaging options, programming configurations, or board-specific revisions rather than core functional differences.

Application Specific Microcontrollers Replacement Considerations

Direct replacements within the MEC1641 family include MEC1641-PZV and MEC1641-PZV-PBC00. Verify pinout and software compatibility when substituting between these variants.
