1 / 124 page  71M6533/H and 71M6534/H Energy Meter IC Simplifying System Integration TM DATA SHEET November 2009 v1.1 © 2007-2009 TERIDIAN Semiconductor Corporation 1 GENERAL DESCRIPTION The 71M6533 and 71M6534 are Teridian’s 3 rd-generation poly- phase metering SOCs with a 10MHz 8051-compatible MPU core, low-power RTC, FLASH and LCD driver. Teridian’s pa- tented Single Converter Technology® with a 22-bit delta-sigma ADC, seven analog inputs, digital temperature compensation, precision voltage reference and a 32-bit computation engine (CE) supports a wide range of metering applications with very few external components. The 71M6533 and 71M6534 add several new features to Teri- dian’s flagship 71M6513 poly-phase meters including an SPI in- terface, advanced power management with <1 µA sleep cur- rent, 4 KB shared RAM and 128 KB (71M6533/H, 71M6534) or 256 KB (71M6534H) Flash which may be programmed in the field with new code and/or data during meter operation. Higher processing and sampling rates and larger memory offer a po- werful metering platform for commercial and industrial meters with up to class 0.2 accuracy. A complete array of ICE and development tools, programming libraries and reference designs enable rapid development and certification of meters that meet all ANSI & IEC electricity meter- ing standards worldwide. FEATURES • Accuracy < 0.1% over 2000:1 range • Exceeds IEC62053 / ANSI C12.20 standards • Seven sensor inputs with neutral current measurement • Low-jitter Wh and VARh plus two additional pulse test outputs (4 total, 10 kHz maximum) with pulse count • Four-quadrant metering • Phase sequencing • Line frequency count for RTC • Digital temperature compensation • Independent 32-bit compute engine • 46-64 Hz line frequency range with same calibration. Phase compensation ( ± 7°) • Three battery back-up modes with wake-up on timer or push-button: Brownout mode (82 µA typ., 71M6533) LCD mode (21 µA typ., DAC active) Sleep mode (0.7 µA typ.) • Energy display during mains power failure • 39 mW typical consumption @ 3.3 V, MPU clock frequency 614 kHz • 8-bit MPU (80515), 1 clock cycle per in- struction, 10 MHz maximum, with integrated ICE for debug • LCD driver with 4 common segment drivers: Up to 228 (71M6533) or 300 (71M6534) pixels • 4 dedicated plus 35 (71M6533) or 48 (71M6534) multi-function DIO pins • RTC for TOU functions with clock-rate adjust register • Hardware watchdog timer, power fail monitor • I2C/Microwire EEPROM Interface • High-speed slave SPI interface to data RAM • Two UARTs for IR and AMR, IR driver with modulation • Flash memory with security and in-system program update: 128 KB (71M6533/H, 71M6534) 256 KB (71M6534H) • 4 KB RAM • Industrial temperature range • 100-pin (71M6533/H) or 120-pin (71M6534/H) lead free LQFP package MPU RTC TIMERS IA VA IB VB XIN XOUT RX TX V1 TX RX COM0..3 V3P3A V3P3SYS VBAT V2P5 IC VC SEG GNDA GNDD SEG/ DIO DIO ICE LIVE LIVE LIVE NEUT LOAD 8888.8888 PULSES, DIO POWER FAULT IR AMR COMPARATOR MOD SERIAL PORTS OSC/ PLL CONVERTER LCD DRIVER DIO ,PULSE COMPUTE ENGINE FLASH RAM 32 kHz REGULATOR CT/ COIL POWER SUPPLY TERIDIAN 71M6533 71M6534 TEMP SENSOR VREF ID BATTERY PWR MODE CONTROL WAKE-up NEUTRAL I 2C or µWire EEPROM 9/24/2008 V2* * 71M6534 only |
