71M6532F - Single-phase 80515 SoCs


  • Four sensor inputs 
    • 80515 MPU with up to 256KB Flash and 4KB RAM
    • RTC, LCD Driver, UARTs, SPI, I2C, and up to 21 GPIO
    • 68-pin QFN and 100-pin LQFP package options


The 71M6531/32 are highly integrated SoC devices with an MPU core, RTC, flash, and LCD driver. The patented 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 and internal battery-backup support for RAM and RTC further reduce system cost. The IC supports 2-wire, 3-wire, and 4-wire single-phase and dual-phase residential metering along with tamper-detection mechanisms. The 71M6531 offers single-ended inputs for two current channels and two single-ended voltage inputs. The 71M6532 have two differential current inputs and three single-ended voltage inputs.
Maximum design flexibility is provided by multiple UARTs, I²C, MICROWIRE™, up to 21 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 TOU, AMR, and prepay meters that comply with worldwide electricity metering standards.
