What are the key features of STCOMET10?
- Integrated ARM Cortex-M4 processor, PRIME/G3-PLC powerline communication modem, and 24-bit metering AFE in a single LQFP-176 SoC, eliminating discrete metering IC and PLC coupler
- 1.2 V core CMOS technology with industrial temperature grade (-40°C to 85°C) enables direct deployment in outdoor utility meter installations without external temperature derating
- LQFP-176 package with 0.4 mm terminal pitch provides sufficient I/O for energy metering display, RTC, tamper detection, and communication interfaces on a single-board smart meter design
What is STCOMET10 used for?
The STCOMET10 is the central SoC for single-phase and poly-phase smart electricity meters requiring narrowband powerline communication over existing LV/MV distribution networks for AMR and AMI deployments. Its integrated PRIME and G3-PLC modems allow utility operators to build DLMS/COSEM-compliant meters that communicate meter readings and firmware updates over the power line without separate RF communication hardware. The 176-pin LQFP package supports all peripheral interfaces needed for a complete smart meter including LCD driver, pulse inputs, RTC, UART, and tamper detection.

Frequently Asked Questions
What powerline communication standards does the STCOMET10 support for smart grid AMI deployments?
The STCOMET10 integrates a narrowband powerline communication modem compatible with PRIME and G3-PLC standards operating in the CENELEC A band (3 kHz to 95 kHz). These two standards cover the majority of European and international smart meter infrastructure deployments, enabling interoperability with existing grid head-end systems and data concentrators.
What processor core is embedded in the STCOMET10 and at what clock speed does it run?
The STCOMET10 integrates an ARM Cortex-M4 processor core with FPU running at up to 120 MHz for the main application domain, plus a dedicated DSP core for PLC signal processing. This dual-core architecture allows concurrent meter data management and PLC communication without performance bottlenecks on either function.
How does integrating metering AFE and PLC modem on one SoC benefit smart meter PCB design?
A single STCOMET10 replaces a discrete metering IC, a separate PLC modem chip, and associated interface logic that would otherwise occupy 3 to 5 separate SOIC or QFN packages on the PCB. This reduces BOM component count by approximately 40 parts, shrinks board area, and simplifies regulatory certification by testing a single integrated device rather than a multi-chip subsystem.
What temperature range is the STCOMET10 rated for in outdoor electricity meter enclosures?
The STCOMET10 carries an industrial temperature grade rating of -40°C to 85°C, matching the IEC 62056 and ANSI C12 meter operating environment requirements for outdoor pole-mounted or underground vault installations. No derating is required for typical meter cabinet temperatures up to 70°C ambient with normal enclosure thermal resistance.
