Version 2.2 DHAN-T DECT-ULE Module Introduction 1. Introduction General Description The DSPG DHAN-T module is based on the state-of-the-art DHX101 - a 4th generation DECT SOC. The DHANT module is well suited for all DECT and ULE Device applications. The DHAN-T SW stack includes standard DECT-ULE MAC-PHY connectivity as well as HAN-FUN (= the ULE Alliance Standard) functionality for DualMode (data and audio) ULE. The Application SW written by the customer typically runs DHX101 within the DHAN-T.

DHAN-T DECT-ULE Module Version 2.2 April 16, 2020 Pinout and Signal Description PIN NO. NAME DESCRIPTION/TYPE 1 GND GND 2 ANT Diversity Antenna. Leave unconnected 3 RSTN For standalone operation, shunt this pin to GND with 100nF. For an application running on an external MCU, this pin should be connected to a Host MCU IO and used to reset the DHAN-T 4 DCINS Leave as not connected (NC) 5 GPIO17 6 SCL (GPIO0) GPIO or I2C Clock. Open Drain, reset value is floating.
DHAN-T DECT-ULE Module Version 2.2 April 16, 2020 PIN NO. NAME 31 GPIO16 32 GND Pinout and Signal Description DESCRIPTION/TYPE GPIO 3V (Doubler) Output. While DHAN-T is hibernating, this pin is either in tristate (default SW configuration) or pulled to GND. Can be used in conjunction with GPIO7&8 above to drive an LED or button during non-hibernation modes 33 DOUT3V0 34 DOUBCAP2P 35 LEDSINK2/DCIN1 36 GND 37 LEDSINK1/PWM 38 DCIN3 39 AMP2_OUT ULE I/O.

Version 2.2 DHAN-T DECT-ULE Module Supplementary Info 5. Interfacing the DHAN-T with an external MCU RSTN Input At power-up, the Application Host on the external MCU should hold this pin (Pin 3) at logic Low until it is ready to establish communication (via UART) with the DHAN-T. When ready, the App Host should apply a rising edge (and leave at Logic High) and wait for the “Hello” indication from the DHAN-T.
Version 2.2 DHAN-T DECT-ULE Module Supplementary Info 6. Application PCB Design Recommendations It is recommended that unused pads on the Application PCB not be left as isolated islands of copper but rather be anchored with via to inner layers of the PCB. It is also recommend that GND vias be applied liberally in the vicinity of GND pins 1, 21, 36 and 56. The following layout recommendations for embedding the DHAN-T on the Application Board: 1. Implement a solid ground under the DHAN-T module 2.

Version 2.2 DHAN-T DECT-ULE Module Supplementary Info Pick & Place, Reflow The DHAN-T module uses a flat shield cover to facilitate a fully automatic assembly process. For backing and reflow recommendations, use MSL 3 in the JEDEC/IPC standard J-STD-20b. The temperature classification (TC) for the module is 245° C. 8.
Version 2.2 DHAN-T DECT-ULE Module Supplementary Info IPEI and EMC Each DHAN-T Module is shipped to the customer with a unique IPEI – its DECT identity. DHAN-T will ship with an “EMC” of 0xFEB. This is the DSP Group “generic” EMC. The EMC setting identifies a Device as belonging to a specific group of ULE Devices/Hubs that utilize some proprietary signaling. In either case, the customer is free to re-program these parameters.
