78M6610+PSU/B00T

Overview

The 78M6610+PSU/B00T is a single-phase energy measurement processor from the 78M6610 series, manufactured by Analog Devices Inc./Maxim Integrated. It integrates an 8051-compatible core with metering peripherals for utility applications. The device operates on a supply voltage of 3 V to 3.6 V and draws a typical supply current of 8.1 mA. It features an input impedance range of 30 kOhm to 90 kOhm. The component is housed in a 24-WFQFN exposed pad package (24-TQFN 4x4) designed for surface mount installation. It supports an operating temperature range from -40°C to +85°C.
