15311R-1000

Overview

The PL 3120 Power Line Smart Transceiver (Model 15311R-1000) is a system-on-a-chip integrating an ANSI-709.1 compliant Neuron 3120 processor core with an ANSI-709.2 compliant power line transceiver. It features 4K Bytes of embedded EEPROM, 2K Bytes of RAM, and 24K Bytes of ROM. The device operates at a maximum input clock frequency of 10MHz, supporting CENELEC C-band signaling with a raw bit rate of 5.4kbps. Designed for compliance with FCC, Industry Canada, Japan MPT, and European CENELEC EN 50065-1 regulations, it utilizes dual carrier frequencies and digital signal processing to ensure reliable communication in noisy environments.

Feature Summary

• Integrates Neuron 3120 processor core with narrow-band power line transceiver
• Compliant with FCC, Industry Canada, Japan MPT, and CENELEC EN 50065-1 standards
• Supports CENELEC A-band and C-band operation via selectable clock frequencies
• Includes 4K Bytes EEPROM, 2K Bytes RAM, and 24K Bytes ROM

Applications

• Appliance control systems
• Audio/video equipment networking
• Lighting control networks
• Heating and cooling management
• Security and metering applications

Procurement Notes

Verify that the specific part number matches the RoHS-compliant Revision B designation (15311R-1000). This variant eliminates the need for an external inverter in the discrete interface circuitry. Confirm compatibility with the required 38-pin TSSOP package dimensions and soldering profiles specified in the datasheet.

Selection Notes

Select this model for designs requiring up to 4K Bytes of application code within an ultra-compact form factor. The PL 3120 does not support external memory interfaces; choose the PL 3150 if larger memory capacity is needed. Ensure the design accommodates the -40 to +85°C operating temperature range and utilizes the recommended discrete interface components for proper signal transmission.

Part Context

The Model 15311R-1000 is the RoHS-compliant version of the PL 3120-E4T10 Power Line Smart Transceiver. It belongs to the Echelon PL 3120/PL 3150 family of smart transceivers designed for cost-sensitive consumer products. The 'R' suffix indicates RoHS compliance, while the base model number identifies the specific silicon revision and package type.

Replacement Considerations

The non-RoHS compliant equivalent is Model 15310-1000. Both share identical electrical specifications and pinouts. Designers must verify that their assembly processes comply with RoHS directives when substituting between these variants.
