The 78M6618 is a highly integrated, single-phase, eight-outlet, PDU power measurement and monitoring SoC that includes a 32-bit computer engine (CE), an MPU core, RTC, and flash. Teridian's Single Converter Technology® with a 22-bit, delta-sigma ADC; 10 analog inputs; digital temperature compensation; and precision voltage reference supports a wide range of single-phase PDU metering applications with very few external components.
With measurement technology leveraged from Teridian's flagship utility metering ICs, the device offers features including 128KB of flash program memory, 4KB shared RAM, three low-power modes with internal timer or external event wake-up, two UARTs, I²C/MICROWIRE™ EEPROM I/F, SPI™ I/F, and an in-system programmable flash.
A complete array of ICE and development tools, programming libraries, and reference designs enable rapid development and certification of power and energy measurement devices that meet most demanding worldwide electricity metering standards.
Applications
- Commercial Power Distribution Units
- Consumer Power Distribution Units
- Subpanels

Product Detail
The TSC flash programmer model TFP2 provides a stand-alone flash memory programming tool for Teridian's embedded controllers. The TFP2 facilitates flash programming in a manufacturing production environment requiring minimum ancillary equipment. Once the TFP2 has been initialized with the target's program code, the target's flash memory can be programmed either manually through operator pushbutton, or controlled by a factory automation computer (ATE).
Applications
- Audio/Video
- Conditional Access and Payment Slots in Digital STB, PVR and Integrated DTVs
- Payphones
- POS Terminals
- SIM Readers in Wireless Devices (WiMAX, GSM, GPRS)
- Vending and Ticketing Machines
78M6618-PDU-1
78M6618 PDU1 Evaluation Board
Product Detail
The Teridian™ 78M6618 PDU1 evaluation board is an example of a low-cost power distribution unit (PDU) utilizing the 78M6618 system-on-chip (SoC). The 78M6618 monitors the AC line voltage and eight load currents, and controls switching of eight internal load relays. The embedded firmware calculates the RMS line voltage and RMS load currents, watts, VAs, VARs, and power factor. The real-time data is transmitted to a PC via a USB interface for display in a Windows®-based graphical user interface (GUI). The 78M6618 UART interface is used as the communications link to an on-board isolated USB interface IC. This document describes the evaluation board with "78M6618 PDU1_DIFF" imprinted on the board. This board is a complete replacement for (and obsoletes) the earlier 78M6618 PDU1 evaluation board
Applications
- Commercial Power Distribution Units
- Consumer Power Distribution Units
- Subpanels
