Product details

Overview

15311R-1000 from Echelon is a RoHS-compliant PL 3120 Power Line Smart Transceiver integrating an ANSI-709.1/709.2-compliant Neuron 3120 processor core with a narrow-band power line transceiver in a 38-pin TSSOP package. It delivers 3.6 kbps (A-band) or 5.4 kbps (C-band) raw bit rate, supports dual-carrier BPSK modulation at 86/75 kHz or 132/115 kHz, and includes 4 KB embedded EEPROM, 2 KB RAM, and on-chip ROM for Neuron firmware - enabling self-contained smart metering and utility control applications.

For engineers reviewing the 15311R-1000 datasheet, 15311R-1000 pinout, 15311R-1000 application, or 15311R-1000 equivalent, this device serves as a complete system-on-chip solution for CENELEC A-band and C-band power line communications, requiring no external memory, supporting in-field firmware updates over the power line, and operating across -40°C to +85°C with integrated power management and 12 configurable I/O pins.

Technical Context

The 15311R-1000 implements a dual-frequency BPSK transceiver with DSP-enhanced receiver, automatic secondary frequency selection upon primary band noise blocking, and patented low-overhead forward error correction. Its Neuron 3120 core executes LonTalk protocol stack and application code directly from on-chip ROM and EEPROM.

It operates at either 6.5536 MHz (for CENELEC A-band utility metering) or 10.0 MHz (for C-band general signaling), with internal 1.8 V VCORE regulator, programmable pull-ups on IO4–IO7 and SERVICE pins, and hardware UART/SPI interfaces supporting up to 115 kbps and 625 kbps respectively.

Equivalent & Alternatives

The following parts are listed as comparable options for similar power line transceiver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
15310-1000	Same PL 3120-E4T10 die, non-RoHS compliant; reflow profile max 235°C vs. 260°C for 15311R-1000	Limited to legacy industrial assemblies not subject to EU RoHS enforcement	Select only if RoHS exemption applies and lead-free assembly is not required.
15321R-960	PL 3150-L10 variant with 64-pin LQFP, 0.5 KB EEPROM, external memory interface (A0–A15, D0–D7, R/W, E), and higher 12–16 mA supply current	Required for applications needing >4 KB application code or external flash/FRAM expansion	Choose when firmware exceeds on-chip EEPROM capacity or real-time data logging demands external memory bandwidth.

Compared with 15310-1000, 15311R-1000 enables lead-free manufacturing and higher thermal tolerance, while 15321R-960 trades EEPROM capacity for external memory scalability - making 15311R-1000 the optimal choice for cost-sensitive, self-contained CENELEC-compliant metering nodes where code size stays under 4 KB.

FAQ

What is the RoHS compliance status of 15311R-1000?

15311R-1000 is explicitly designed to comply with European Directive 2002/95/EC (RoHS), as confirmed in the official ordering information table. Its reflow soldering profile supports peak temperatures up to 260°C, meeting JEDEC J-STD-020C requirements for lead-free assembly - distinguishing it from the non-RoHS 15310-1000 variant.

Does 15311R-1000 support both CENELEC A-band and C-band operation?

Yes, 15311R-1000 supports both bands: configure XIN to 6.5536 MHz for CENELEC A-band (86/75 kHz carriers, utility metering), or 10.0 MHz for C-band (132/115 kHz, general signaling). The CENELEC access protocol is implemented in hardware and can be enabled/disabled via firmware - no external components needed to switch bands.

How much application code can be stored on 15311R-1000?

15311R-1000 includes 4 KB of embedded EEPROM rated for 10,000 write cycles and 10-year data retention. This space holds both application code and configuration data. The Neuron 3120 firmware resides in 24 KB of on-chip ROM, leaving the full 4 KB EEPROM available for user applications - sufficient for typical metering, lighting, and HVAC control logic.

What interfaces does 15311R-1000 provide for host microcontroller communication?

15311R-1000 provides a full-duplex hardware UART (up to 115 kbps) and SPI interface (up to 625 kbps) on shared pins IO8–IO10. These allow direct connection to host MCUs without level-shifting or protocol translation. No external transceivers or bridge ICs are required - simplifying design and reducing bill-of-materials cost.

Can 15311R-1000 perform in-field firmware updates over the power line?

Yes, 15311R-1000 supports remote firmware updates over the power line network using the LonTalk protocol. Application code stored in its 4 KB EEPROM can be rewritten without physical access - enabling centralized maintenance for deployed smart meters, streetlights, or irrigation controllers via local PC or i.LON Internet Server.
