REVISION HISTORY
The following major modifications and improvements have been made to the first version of
this document:
No
1.01
1.02
1.03
1.10
1.20
Major Changes
Tape running direction added in 3.8
Dimension of TCM 320 corrected (width 18 mm instead of 19 mm)
Editorial changes
Timing information regarding serial protocol added in A.2, A.3. 0xFFFF_FFFF ex-
cluded from usable ID range, because this ID will be used as broadcast ID.
Error corrected in 3.2.1. and 4.1: Maximum gain of external antenna at 50Ohm
output RF_50 is 0dBi! Error corrected in 2.2: WXODIO is configured as output and
provides information on VON signal
Note added in 3.5
Remarks added regarding use of IOVDD in 2.2.; Antenna specification in 3.3.1 ex-
tended. Updated information on conducted output power in 1.2; A.2.2 changed to
point to EnOcean Alliance Website; A.2.3 and A.2.4 removed; editorial changes

GENERAL DESCRIPTION
Basic functionality
The transceiver modules TCM 300 / 300C and TCM 320 / 320C
enable the realization of highly efficient RF repeaters and
transceivers for the EnOcean 868 MHz and 315 MHz radio sys-
tems. The module provides several built-in operating modes.
In addition repeater functionality (1 or 2 level) can be acti-
vated. Using the Dolphin API library it is possible to write cus-
tom software for the module. All module variants are in-system
programmable.
Built-in operating modes
Unidirectional serial communication
Bidirectional serial communication
1-channel relay mode
4-channel relay mode
1-channel dimming mode
Product variants
TCM 300/300C: SMD mountable module for use with external antenna (868/315 MHz)
TCM 320/320C: Variant for vertical mounting with pin connector. Whip antenna.
(868/315 MHz). TCM 320C is backward compatible to TCM 220C
Features accessible via API:
Integrated 16 MHz 8051 CPU with 32 KB FLASH and 2 kB SRAM
Various power down and sleep modes
TCM 300/300C down to 0.2 µA current consumption
TCM 320/320C down to 1.4 mA current consumption
Up to 14 configurable I/Os (TCM 300/300C)
10 bit ADC, 8 bit DAC
