The 71M6521BE is a highly integrated SoC with an MPU core, flash, and LCD driver. Teridian's Single Converter Technology® with a 22-bit, delta-sigma ADC; four analog inputs; digital temperature compensation; precision voltage reference; battery voltage monitor; and 32-bit computation engine (CE) supports a wide range of residential metering applications with very few low-cost external components. A 32kHz crystal time-base for the entire system further reduces system cost. The IC supports 2-wire single-phase residential metering along with tamper-detection mechanisms.

Maximum design flexibility is provided by multiple UARTs, I²C, MICROWIRE™, up to 14 DIO pins, and in-system programmable flash memory, which can be updated with data or application code in operation.

A complete array of ICE and development tools, programming libraries, and reference designs enable rapid development and certification of AMR and prepay meters that comply with worldwide electricity metering standards.

Applications

  • Residential Meters, 0.5% Accuracy

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
