TCM 515Z – 2.4 GHZ IEEE 802.15.4 Transceiver
1 GENERAL DESCRIPTION
1.1 Basic functionality
TCM 515Z enables the realization of line-powered actuators, controllers and gateways
communicating based on the 2.4 GHz IEEE 802.15.4 radio standard. It provides a transparent radio link between EnOcean 2.4 GHz devices and an external host connected via the
standardized ESP3 interface (EnOcean Serial Protocol, version 3).
TCM 515Z receives and transmits radio telegrams based on a 50 Ohm or whip antenna
connected to the host PCB. It forwards received 2.4 GHz IEEE 802.15.4 radio telegrams
to an external host processor or host PC via the ESP3 interface.
IEEE 802.15.4 messages received from an external host via the ESP3 interface will be
transmitted by TCM 515Z as 2.4 GHz radio telegrams.
TCM 515Z is implemented as 31 pin reflow-solderable module with optimized form factor
for size constrained applications.
Figure 1 below shows TCM 515Z.

2 FUNCTIONAL INFORMATION
2.1 TCM 515Z Device Interface
TCM 515Z implements a 31 pin reflow-solderable interface. Solder mask data is available
on request from EnOcean. The pin assignment (as seen from the top of the device) is
shown in Figure 2 below.
Figure 2 – TCM 515Z device interface
Table 1 below summarizes the signal assignment.
Table 1 - TCM 5151Z device interface pin assignment
Signals marked with “NC” are reserved for production test and future device variants and
must not be connected in the design.

USER MANUAL
TCM 515Z – 2.4 GHZ IEEE 802.15.4 Transceiver
2.1.1 Signal Description
TCM 515Z is supplied by the VDD and GND Pins. The required supply voltage is 3.3V with a
tolerance of no more than +-10%.
TCM 515Z receives and transmits data based on a 50Ω whip antenna connected to its ANTENNA input (Pin 2).
TCM 515Z communicates with the external host using the standard ESP3 serial (UART) interface based on the signals UART_TX (Pin 21, direction from TCM 515Z to external host)
and UART_RX (Pin 20, direction from external host to TCM 51Z).
The default interface speed of the ESP3 interface is 57600 bit per second (the exact speed
is 57347 Bit per second, a deviation of -0.04%).
It is possible to select faster communication speeds of 115200, 230400 and 460800 bit per
second during operation using the CO_SET_BAUDRATE command as shown in Table 16.
Additionally it is possible to change the default ESP3 interface speed at power up from
57.600 Bit per second to 460.800 Bit per second by connecting the TURBO input (Pin 31) to
Ground. Subsequent modification of the interface speed during operation using the
CO_SET_BAUDRATE command is always possible irrespective of the state of the TURBO
input pin.
2.2 High-level operation principle
In receive mode, TCM 515Z forwards the content of received IEEE 802.15.4 radio telegrams
(which pass frame check sum validation) unmodified to the external host via the ESP3 interface.
The forwarded frame starts with the Length field of the IEEE 802.15.4 PHY Header, continues with the MAC Header and ends with the last Byte of the MAC Payload. The frame check
sum (MAC Trailer) will not be forwarded to the host.
In transmit mode, TCM 515Z receives from the external host the precomputed message
payload starting with the Length field of the IEEE 802.15.4 PHY Header, continuing with the
MAC Header and ending with the last Byte of the MAC Payload.
TCM 515Z then calculates the frame check sum (MAC Trailer) and appends it to the message. The full frame (including the Preamble and Start of Frame fields) will then be transmitted as IEEE 802.15.4 radio telegram (TX mode).

USER MANUAL
TCM 515Z – 2.4 GHZ IEEE 802.15.4 Transceiver
2.3 Supported Radio Channels
TCM 515Z support all radio channels of the IEEE 802.15.4 standard in the 2.4 GHz band.
The radio channel used by TCM 515Z can be set by an external host using the ESP3
SET_CHANNEL command as described in Appendix C.2.3.
The channel notation used by TCM 515Z follows IEEE 802.15.4 standard, i.e. channel 11 is
the first channel (lowest frequency) and channel 26 is the last channel (highest frequency).
Table 2 below shows the correspondence between channel ID and channel frequency.

USER MANUAL
TCM 515Z – 2.4 GHZ IEEE 802.15.4 Transceiver
2.4 ESP3 Interface
TCM 515Z provides a bi-directional UART interface for communicating with the external
host. The default baud rate of this interface is 57600 bps. If the TURBO pin is set to active
low then the baud rate is increased to 460.800 bps.
2.4.1 ESP3 Data Format
TCM 515Z communicate with external hosts using EnOcean Serial Protocol version 3 (ESP3)
with EnOcean 2.4 GHz IEEE 802.15.4 extensions.
Please consult the detailed ESP3 specification at https://www.enocean.com/esp.
2.4.2 Supported ESP3 Commands

Packet Type 0x10: IEEE 802.15.4 Raw Packet
Packet Type 0x11: IEEE 802.15.4 COMMAND
o SET_CHANNEL
o GET_CHANNEL
Packet Type 0x05: Common Command
