Specified Low Power Radio - UHF Transceiver LSIs

The ML7345 is a low power RF transceiver for narrow band in Sub-GHz. The ML7345 includes RF, IF, MODEM, baseband processor, HOST interface. The ML7345 supports RF frequency sets of 160MHz to 960MHz, and implements programmable channel filters supporting 12.5kHz or wider channel spacing. ML7345 is suitable to F mode (434MHz) ,N mode (169MHz) and C/R/S/T mode(868MHz) of Wireless M-Bus in Europe, and to RCR STD-30 and ARIB STD-T67 in Japan.
The ML7345D supports 750MHz - 960MHz in frequency band. Also ML7345D supports the system of channel intervals more than 12.5kHz and 50kHz because the band variable channel select filter is implemented. It can be based on the C/R/S/T mode (868MHz) in the European tele meter standard (Wireless M-Bus) and specific low power radio station in Japan.
The ML7345 series has the same package, pins assignment and major registers as the ML7344/ML7406 family for sharing the board and software between narrow/broadband Sub-GHz applications.
