Key Features
- Integrated powerline communication (PLC) modem and smart metering functions in a single CMOS SoC reduce BOM complexity and PCB area compared to discrete metering plus communication solutions
- 176-pin LQFP package with 0.4 mm fine pitch and gull-wing terminals enables high-density PCB routing for compact smart meter mainboard designs
- Industrial temperature grade CMOS process operating at 1.2 V nominal supply ensures reliable operation across the full temperature range of outdoor energy metering equipment
Applications
The STCOMET05 is designed for single-phase and multi-phase smart electricity meters that require integrated powerline communication for AMI network connectivity and tamper detection. It is used by smart grid hardware manufacturers in residential and commercial energy meters where combining the PLC modem, metrology front-end, and MCU core in one SoC reduces board area and production cost. The industrial temperature grade and 176-pin LQFP packaging make it suitable for DIN-rail mounted metering equipment and outdoor utility installations requiring long service life.

Frequently Asked Questions
What supply voltage and package does the STCOMET05 use, and how does this affect PCB design?
The STCOMET05 operates at a 1.2 V nominal core supply and is housed in a 176-pin LQFP with 0.4 mm terminal pitch. The fine-pitch gull-wing package requires precise SMT placement and reflow soldering to maintain solder joint integrity on all 176 pads, necessitating careful stencil design and controlled reflow profiles in the smart meter assembly process.
What powerline communication standard does STCOMET05 support, and at what frequency band?
The STCOMET05 integrates a powerline communication modem compatible with PRIME or G3-PLC standards, operating in the CENELEC A band (3 kHz to 95 kHz) for smart meter-to-concentrator AMI network communication. This band is mandated for smart grid deployments across many European and international utility networks, enabling the SoC to interface directly with the power distribution network carrier.
How does STCOMET05 compare to using separate metering ICs and PLC modems on a smart meter board?
Integrating metrology, MCU, and PLC modem into the single-chip STCOMET05 eliminates at least 2 to 3 separate ICs that would otherwise consume 30% to 50% more PCB area, require additional inter-chip SPI or UART interfaces, and increase firmware integration complexity. This reduces smart meter mainboard bill-of-materials cost and simplifies IEC 62056 certification scope.
What temperature range does STCOMET05 support, and is it appropriate for outdoor electricity meter enclosures?
The STCOMET05 is rated to industrial temperature grade, typically covering -40°C to +85°C, which encompasses the operating temperature range specified by IEC 62052 for outdoor electricity metering enclosures. This rating ensures the SoC maintains metrology accuracy and PLC communication reliability in direct-sunlight meter boxes and cold-climate utility installations.
