ML7344C/E/J
Sub-GHz(160MHz to 510MHz) band short range wireless transceiver IC
FEDL7344C/E/J-05
Issue Date: Jan 20, 2015
Overview
ML7344C/E/J is a narrow band sub-GHz IC that integrates RF part, IF part, MODEM part and HOST interface
part in single-chip. It supports various frequency band from 160MHz to 510MHz. ML7344C can output 100mW
(20dBm) transimittion power and it suits for the smart-meter in Chinese market. ML7344E is suitable for Fmode
(434MHz) or N mode (169MHz) of Wireless M-Bus system. ML7344J is suitable for security radio system type III
or IV of the RCR STD-30 and specified low-power radio station in 426 MHz operation of the ARIB STD-T67.
ML7406 and ML7344 have the same package, pins assignment and
major registers.
