Frequently Asked Questions
What is the METERS AND MORE standard, and how does ST75MM's compliance benefit smart grid deployments?
METERS AND MORE is a CENELEC-compliant narrowband power line communication protocol operating in the 9 kHz to 95 kHz CENELEC A-band, standardized for European smart metering. ST75MM's compliance ensures interoperability with multi-vendor AMI infrastructure, allowing utilities to mix meters from different manufacturers on the same 50 Hz distribution grid without proprietary gateway hardware.
How does integrating the PLC modem and microcontroller on one chip in ST75MM reduce BOM compared to a discrete approach?
A discrete solution requires a separate PLC analog front-end, a microcontroller, external Flash, and line coupling components, typically adding 5 to 8 active ICs. ST75MM integrates the modem, processor, and memory in a single QFN SoC, reducing active component count by roughly 60% and shrinking the metering PCB footprint by several square centimeters.
What peak reflow temperature does ST75MM support, and what assembly process does that enable?
ST75MM supports a peak reflow temperature of 260°C for up to 30 seconds, meeting J-STD-020 MSL requirements for lead-free SAC305 solder paste assembly. The Ni/Pd/Au terminal finish ensures reliable solder joint formation at this temperature and prevents tin whisker growth, making it compatible with modern RoHS-compliant PCB manufacturing lines.
For a multi-apartment building metering project, how many ST75MM-based meters can realistically share one PLC communication segment?
METERS AND MORE PLC networks typically support several hundred nodes per segment on a single 230V distribution transformer secondary, with data rates up to 2.4 kbps for metering data frames. A typical residential building with 50 to 200 apartments can be served from a single segment, with ST75MM's integrated modem handling the CSMA/CA collision avoidance needed for reliable multi-node coexistence.
