Hardware Description
4.2.1.
Function Description
KX-TDA0158CE is the Cell Station (CS) for TDE series. CS converts voice data from PBX to radio signal and transmits to DECT
Portable Station (PS). Conversely CS converts radio signal from PS to voice data and transmits to PBX.
This unit is composed of 2 different PCBs. One is the Control Board to handle voice data and control data from PBX.
The other is the RF module to transmit and receive RF signal.

BUS Access Circuit
The BBIC (IC100) has built-in MPU. This BBIC processes control command from PBX and PS.
Application software is stored in 32Mbit Flash Memory (IC101). This Flash Memory is so called Dual Operation type Flash. It is
possible to write data onto this Flash Memory in active status so that this Flash Memory is used as EEPROM. Some calibration
data such as RSSI and clock are stored in the Flash Memory.
2Mbit SRAM is used as the work area. CN101 is the communication port for service purpose. CN101 is connected to the serial
port of the BBIC.
SW100 is 6bits DIP switch to set the operating modes of CS.
