Descriptions
The RFM213W is an ultra low power, high performance,
low-cost (G)FSK/OOK stand-alone RF receiver for various
300 to 480 MHz wireless applications. It is part of the
CMOSTEK NextGenRFTM family, which includes a
complete line of transmitters, receivers and transceivers. An
embedded EEPROM allows the frequency, symbol rate and
other features to be programmed into the device using the
CMOSTEK USB Programmer and RFPDK. Alternatively, in
stock products of 433.92 MHz is available for immediate
demands with no need of EEPROM programming. The
RFM213W operates from a supply voltage of 1.8 V to
3.6
V, when it is always on, it consumes only 4.3 mA current
while achieving -111 dBm receiving sensitivity. It consumes
even less power when working in duty-cycle operation
mode via the built-in sleep timer. The device provides
demodulated data, power-on reset output as well as a
system clock output for use by an external microcontroller
or decoder. The RFM213W receiver together with
the
RFM113 transmitter enables an ultra low cost RF link.

5.3 Embedded EEPROM and RFPDK
The RFPDK is a PC application developed to help the user to configure the CMOSTEK NextGenRFTM products in the most
intuitional way. The user only needs to connect the USB Programmer between the PC and the device, fill in/select the proper
value of each parameter on the RFPDK, and click the “Burn” button to program the configurations into the device. The
configurations of the device will then remain unchanged until the next programming. No external MCU control is required in the
application program.
The RFPDK also allows the user to save the active configuration into a list by clicking on the “List” button, so that the saved
configuration can be directly reloaded from the list in the future. Furthermore, it supports exporting the configuration into a
hexadecimal file by clicking on the “Export” button. This file can be used to burn the same configuration into a large amount of
devices during the mass production. See the figure below for the accessing of the EEPROM.

Link Development Kits Users Guide”.
5.4 All Configurable Options
Beside the demodulation, frequency and symbol rate, more options can be used to customize the device. The following is a table
of all the configurable options. On the RFPDK, the Basic Mode only contains a few options allowing the user to perform easy and
fast configurations. The Advanced Mode shows all the options that allow the user to customize the device in a deeper level. The
options in “Basic Mode” are a subset of that in the “Advanced Mode”.
