Product details
Overview
SM2400A-MQEQ-Y from Adesto Technologies is a narrowband power line communication (N-PLC) transceiver SoC with dual-core architecture, integrated 256-bit AES-CCM* encryption engine, configurable 5–500 kHz operational band compliant with CENELEC/FCC/ARIB, OFDM/FSK/S-FSK modulation support, and receiver sensitivity of −80 dBV - deployed in smart metering and AMI systems.
For engineers reviewing the SM2400A-MQEQ-Y datasheet, SM2400A-MQEQ-Y pinout, SM2400A-MQEQ-Y application, or SM2400A-MQEQ-Y equivalent, key selection criteria include IEEE 1901.2/G3-PLC/PRIME protocol compliance, programmable modulation schemes (BPSK/QPSK/8PSK/16QAM), embedded RISC protocol engine, SPI/UART host interface, and LQFP64 package compatibility with industrial temperature range (−40 °C to +105 °C).
Technical Context
The SM2400A-MQEQ-Y implements a dedicated DSP core for PHY-layer signal processing and a 32-bit RISC controller for MAC/data link layer operations, enabling concurrent real-time OFDM tone mapping, adaptive bit loading, and jammer cancellation. It supports both standardized (IEEE 1901.2, G3-PLC 1.3.6/1.4, PRIME) and proprietary robust modes (XR, XXR) with full firmware configurability.
Analog front-end integration includes 12-bit ADC/DAC, two programmable gain op-amps, PGA, and zero-crossing detector input - all optimized for direct coupling to external high-voltage line drivers. Boot options include SPI master, UART CI, and SPI slave interfaces, with firmware loaded from internal memory or external SPI flash.

FAQ
What communication standards does the SM2400A-MQEQ-Y support out of the box?
The SM2400A-MQEQ-Y supports IEEE 1901.2, G3-PLC 1.3.6 and 1.4, PRIME, and CTIA/EIA-709.2 via preloaded firmware bundles. It also implements proprietary XR and XXR modes for non-standardized, ultra-robust operation. All standard modes are fully certified and field-deployed in utility AMI networks. The SM2400A-MQEQ-Y does not require external protocol stack licensing.
Does the SM2400A-MQEQ-Y include an integrated analog front end?
Yes, the SM2400A-MQEQ-Y integrates a complete analog front end: 12-bit ADC, 12-bit DAC, programmable gain amplifier (PGA), and two op-amps for RX and TX signal conditioning. This eliminates the need for external AFE components in most N-PLC designs, reducing BOM count and PCB area. External coupling circuitry and a high-voltage line driver remain required.
What is the operating temperature range of the SM2400A-MQEQ-Y?
The SM2400A-MQEQ-Y is rated for −40 °C to +105 °C ambient operation, qualified per AEC-Q100 stress test requirements for automotive-grade reliability. This range supports deployment in outdoor meter enclosures, underground junction boxes, and streetlight control cabinets exposed to direct sunlight or freezing conditions. The SM2400A-MQEQ-Y maintains full performance across this range without derating.
How is firmware loaded onto the SM2400A-MQEQ-Y?
Firmware for the SM2400A-MQEQ-Y can be loaded via four boot modes: SPI master (from external flash), UART command interface, SPI slave (host MCU-driven), or reserved. Firmware executes from internal memory after boot. No external ROM or EEPROM is required. The SM2400A-MQEQ-Y supports field firmware updates over UART or SPI without hardware reset.
Is the SM2400A-MQEQ-Y pin-compatible with earlier SM2400 variants?
Yes, the SM2400A-MQEQ-Y maintains identical LQFP64 pinout and electrical characteristics with prior SM2400 family members (e.g., SM2400A-MQEQ-W). All GPIO, analog, and interface signals retain the same assignment and timing behavior. Migration requires only firmware update - no PCB redesign or layout changes are needed when upgrading to SM2400A-MQEQ-Y.
