RFM12

General Introduction

RFM12 is a low costing ISM band transceiver

module implemented with unique PLL. It works

signal ranges from 315/433/868/915MHZ bands,

comply with FCC, ETSI regulation. The SPI

interface is used to communicate with

microcontroller for parameter setting.

Features:

• Low costing, high performance and price ratio

• Tuning free during production

• PLL and zero IF technology

• Fast PLL lock time

• High resolution PLL with 2.5 KHz step

• High data rate (up to 115.2 kbps with internal demodulator，with external RC filter highest data rate is

256 kbps)

• Differential antenna input

• Automatic antenna tuning

• Programmable TX frequency deviation (from 15 to 240 KHz)

• Programmable receiver bandwidth (from 67 to 400 kHz)

• Analog and digital signal strength indicator (ARSSI/DRSSI)

• AFC

• DQD

• Internal data filtering and clock recovery

• RX synchron pattern recognition

• SPI interface

• Clock and reset signal output for external MCU use

• 16 bit RX Data FIFO

• Two 8 bit TX data registers

• 10MHz crystal for PLL timing

• Wakeup timer

• 2.2V - 5.4V power supply

• Low power consumption

• Standby current less than 0.3uA
