FAQ
What is the primary function of the MEC1641-PZV-PBC01-TR in a notebook system?
The MEC1641-PZV-PBC01-TR serves as the base embedded controller in split-architecture Advanced I/O Controllers, managing power states (S0ix/S3/S4/S5), keyboard scanning, thermal monitoring via PECI and ADC, and ACPI event generation. Its ARC625D core executes firmware that coordinates with companion devices over BC-Link™, making MEC1641-PZV-PBC01-TR central to instant-on behavior and system-level power efficiency.
Does the MEC1641-PZV-PBC01-TR support direct connection to the host CPU?
Yes, the MEC1641-PZV-PBC01-TR interfaces directly with the host CPU via the Intel® Low Pin Count (LPC) bus, supporting standard LPC frame protocols including firmware memory access, SMI assertion, and SCI event signaling. This ensures compatibility with Intel and AMD platform controllers without requiring bridge ICs-confirming MEC1641-PZV-PBC01-TR's role as a native LPC endpoint.
How does the BC-Link™ interface work with the MEC1641-PZV-PBC01-TR?
The MEC1641-PZV-PBC01-TR uses BC-Link™ as a dedicated two-wire (clock/data) serial interface to communicate with companion I/O devices like the MEC1642. It offloads GPIO expansion, PWM generation, and additional ADC channels to those devices, reducing firmware load and pin count on MEC1641-PZV-PBC01-TR itself-enabling scalable I/O without increasing EC complexity.
What power supply configurations does the MEC1641-PZV-PBC01-TR require?
The MEC1641-PZV-PBC01-TR requires three independent supplies: VBAT (3.0–3.6V) and VTR (3.0–3.6V) for suspend-state retention, and VCC (1.8V) for runtime operation. VCC sensing triggers power mode transitions, while VBAT/VTR maintain RTC, wake logic, and SRAM contents during S3/S4/S5-ensuring MEC1641-PZV-PBC01-TR delivers true instant-on capability.
Is the MEC1641-PZV-PBC01-TR compatible with PECI 3.0 for CPU thermal telemetry?
Yes, the MEC1641-PZV-PBC01-TR integrates a native PECI 3.0 interface compliant with Intel specification, enabling direct readout of CPU digital thermal sensors (DTS), Tjmax, and thermal throttling status. This allows MEC1641-PZV-PBC01-TR to implement precise, low-latency fan control and thermal policy enforcement without host CPU intervention.
