GENERAL DESCRIPTION
A 32-kHz crystal time base for the entire system and internal battery backup support for RAM and RTC further reduce system cost. The 71M6531D/F offers single-ended inputs for two current channels and two single-ended voltage inputs. The 71M6532D/F has two differential current inputs and three single-ended voltage inputs. Maximum design flexibility is provided by multiple UARTs, I2C, μWire, 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.
