Transceiver Modules
TCM 300 / 300C
and TCM 320 / 320C
The transceiver modules TCM 300 /300C
and TCM 320 / 320C enable the realization
of highly efficient RF repeaters and tran-
sceivers for the EnOcean 868 MHz and 315
MHz radio systems.
The module provides several built-in operating
modes. In addition a repeater functionality
(1 or 2 level) can be activated. Using the Dolphin
API library it is possible to write custom software
for the module. The modules are in-system pro-
grammable.
Built-in operating modes
Unidirectional serial communication
Bidirectional serial communication
1-channel relay mode
4-channel relay mode
1-channel dimming mode
Features accessible via API:
Integrated 16MHz 8051 CPU with
32KB FLASH and 2kB SRAM
Various power down and sleep modes
down to 0.2 µA current consumption
Up to 14 configurable I/Os
10bit ADC, 8bit DAC
Energy Harvesting made easy with
EnOcean wireless standard
TCM 300 is a bidirectional system module for
maintenance-free sensor solutions based on the
EnOcean wireless standard.

EnOcean Dolphin System Architecture.
Open. Flexible. Expandable.
The distinguishing feature that sets Dolphin apart
from other wireless system architectures is energy
harvesting, which enables self-powered wireless
sensors and actuators. The Dolphin system architec-
ture joins the components necessary for an energy-
autonomous wireless sensor system that operates
on a standardized wireless network. These include
energy conversion and storage components,
EnOcean wireless modules for energy management,
data acquisition, data processing and wireless data
transmission, and finally the software blocks operat-
ing system, API and application programs.
As an open and expandable hardware and software
architecture, Dolphin is future-oriented and fully
backward compatible with EnOcean-enabled devices
and system components already on the market.
The hardware kernel of Dolphin is the EO3000I chip,
a basis for simply integrated modules. EnOcean
modules already have extensive firmware functio-
nality implemented – such as basic switching, dim-
ming and measuring – and can go straight into an
application without additional programming. Its
built-in application functions enable straightforward
start-up and system integration.
Benefits for OEM partner

harvesting
Simple expansion of portfolio to wireless-based
products using EnOcean wireless standard
Ready available and wide-ranging, interoperable
system product portfolio
Fast implementation and time to market
Low investment in R&D, T&M, etc
Various evaluation tools obtainable to support
development
EnOcean Development Kit EDK 300 for TCM 300
