71M6545T中文资料多相电力仪表SoC数据手册Silergy规格书

描述 Description

The 71M6545T metrology processors are based on 4th-generation metering architecture supporting the 71M6k series of isolated current sensing products that offer drastic reduction in component count, immunity to magnetic tampering, and unparalleled reliability. The 71M6545T integrate our Single Converter Technology with a 22-bit delta-sigma ADC, a customizable 32-bit computation engine (CE) for core metrology functions, as well as a user-programmable 8051-compatible application processor (MPU) core with up to 64KB flash and up to 5KB RAM.An external host processor can access metrology functions directly through the SPI interface, or alternatively through the embedded MPU core in applications requiring metrology data capture, storage, and preprocessing within the metrology subsystem. In addition, the devices integrate an RTC, DIO, and UART. A complete array of ICE and development tools, programming libraries, and reference designs enable rapid development and certification of meters that meet all ANSI and IEC electricity metering standards worldwide.Contact support.metering@silergy.com to request additional information, check availability, or obtain copies of data sheets for earlier non-T versions of the 71M654x.
