The new 71M6521 product family represents Teridian’s second

generation electricity metering technology for cost sensitive

residential applications. This SOC device is footprint compatible

with 71M6511, integrates AFE, MCU, RTC, FLASH and LCD driver

but offers lower cost 8/16/32 KB FLASH options, more I/O,

advanced power management and tamper detection. Teridian’s

patented Single Converter Technology

with a 22bit 2^ndorder

• 40-70Hz frequency range with phase

compensation (±7°)

delta-sigma converter,

4 analog inputs, digital temperature

compensation, voltage reference and flexible 32-bit computation

engine meet all current and evolving metering requirements

worldwide with minimal external components.

• 8-bit MPU (80515), 1 instruction/cycle

• 2kB MPU Data RAM

• 0.5KB CE Data RAM

• 8, 16 or 32 KB FLASH with Security

• Mask ROM option

• Real Time Clock (6521D/F models)

• Temp. sensor for RTC compensation

• Battery backup for RTC w/ Battery monitor

Low system cost is supported with 2 UARTs, I²C/µWire EEPROM

interface, battery monitor, power fail monitor, neutral current or

magnetic tamper detection, program/data FLASH, mask ROM

option and operation with capacitive power supply.

Teridian’s large portfolio of solutions for residential, commercial and

industrial metering offers OEMs a comprehensive array of ICs,

tools, reference designs and above all a unique ability to

differentiate their products in the market.
