Product details
Overview
The MAX2990ECB+T from Maxim Integrated is a highly integrated power line communication (PLC) baseband modem SoC combining PHY and MAC layers, featuring a 16-bit MAXQ microcontroller core, 32kB flash, 8kB SRAM, and OFDM modulation for robust 100kbps data transmission over AC power lines in FCC/ARIB/CENELEC bands.
For engineers reviewing the MAX2990ECB+T datasheet, MAX2990ECB+T pinout, MAX2990ECB+T application, or MAX2990ECB+T equivalent, key selection considerations include its 64-pin LQFP package, -40°C to +85°C operation, DES encryption engine, jammer cancellation, CSMA/CA channel arbitration, and support for SPI/I²C/UART host interfaces.
Technical Context
The MAX2990ECB+T implements a full PLC protocol stack with integrated MAXQ RISC MCU executing MAC-layer logic while offloading OFDM PHY processing-including BPSK modulation, FEC encoding/decoding, CRC16/CRC32, and jammer cancellation-to dedicated hardware blocks synchronized via shared 4kB dual-access SRAM.
Its frequency agility spans 10kHz–490kHz with user-configurable start/end frequencies, supporting CENELEC A/B/C, FCC, and ARIB spectral masks; channel access uses CSMA/CA with ARQ retransmission, and time-stamped operations leverage an on-chip RTC.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PLC modem applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST7580 | Lacks integrated MCU; requires external host for MAC layer; supports only CENELEC A/B bands (no FCC/ARIB). | No built-in DES engine or RTC; relies on host for encryption and time stamping. | Choose when cost-sensitive designs can allocate MCU resources externally and operate only in European utility bands. |
| INT51x1 | Uses QPSK instead of BPSK-OFDM; lower peak-to-average ratio but reduced impulsive noise resilience. | Does not include jammer cancellation or hardware DES; supports only SPI interface (no I²C/UART). | Prefer where spectral efficiency is prioritized over noise robustness and host interface flexibility is limited. |
Compared with ST7580 and INT51x1, the MAX2990ECB+T provides full PHY+MAC integration, FCC/ARIB spectral coverage, jammer cancellation, and hardware DES-making it uniquely suited for globally deployable, secure, and noise-resilient PLC endpoints requiring minimal external components.

FAQ
What communication standards does the MAX2990ECB+T support?
The MAX2990ECB+T complies with CENELEC A (10–95kHz), B (95–120kHz), and C (120–140kHz), FCC (10–490kHz), and ARIB (10–450kHz) spectral regulations. It achieves this through user-configurable start/end frequencies and OFDM tone mapping aligned to each standard's mask requirements-ensuring global interoperability without hardware modification. The MAX2990ECB+T implements these standards in silicon via dedicated PHY blocks, not software-only adaptation.
Does the MAX2990ECB+T require an external microcontroller?
No-the MAX2990ECB+T integrates a 16-bit MAXQ RISC microcontroller with 32kB flash and 8kB SRAM, enabling standalone execution of MAC-layer protocols, application logic, and host interface management. External MCUs are optional and used only for higher-level system coordination; the MAX2990ECB+T handles all PLC-specific processing internally, including OFDM symbol generation, FEC encoding, and DES encryption.
How does jammer cancellation work in the MAX2990ECB+T?
The MAX2990ECB+T employs adaptive narrowband interference cancellation in its analog front-end and digital signal path to suppress constant sinusoidal jammers (e.g., switching power supplies) within FCC and ARIB bands. This is implemented as a real-time feedback loop that estimates and subtracts jammer components before OFDM demodulation-verified to improve SNR by >15dB in lab and field tests. The MAX2990ECB+T performs this autonomously without host CPU involvement.
What host interfaces does the MAX2990ECB+T provide?
The MAX2990ECB+T offers SPI, I²C, and UART interfaces for host connectivity. SPI supports up to 10MHz clock rates for high-throughput register access and bulk data transfer; I²C operates at standard/fast mode (100kHz/400kHz) for low-pin-count control; UART provides asynchronous debugging and legacy integration at configurable baud rates. All three interfaces are simultaneously active and independently configurable in the MAX2990ECB+T's register map.
Is the MAX2990ECB+T suitable for battery-powered endpoints?
The MAX2990ECB+T supports low-power operation modes including deep-sleep (10µA typical) and standby with RTC wake-up, making it viable for battery-backed PLC sensors. Its integrated RTC enables time-triggered transmissions, and the built-in test mode engine allows channel assessment without continuous PHY activation. However, full 100kbps operation draws ~120mA; optimal battery life requires duty-cycled use of the MAX2990ECB+T's sleep states and selective peripheral enablement.
