Introduction The model C410 is a 40 channel (902 MHz - 928 MHz) cordless telephone. This unit is made up of two parts: a. A Handset unit. b. A Base unit. 2. Functional Blocks of the Handset The block diagram of C410 handset unit is as shown below. It is made up of the following parts: 2.1 Keyboard Matrix, Switches and Function LED 2.2 MCU and MCU Interface 2.3 RF Module 2.4 Compander 2.5 Data Shaper 2.6 Charge and Control 2.7 Low Battery Detector 2.8 Buzzer 2.9 Audio Circuit Revision 00 2of 18 C410 Handset Unit Block Diagram Revision 00 3of 18 3. Handset Unit Circuit Block Description 3.1 Keyboard Matrix, Switches and Function LED The keyboard consists of the following keys: • FIRE – one touch memory key • POL – one touch memory key • AMB – one touch memory key • CHN – for changing RF carrier frequency • TALK – for On/Off hook control • MEM – for memory program and dialing • 1, 2, 3, 4, 5, 6, 7, 8, 9, *, 0, # – numeric keys • FLASH – provides timed On/Off hook function • MUTE – turns Off/On the handset microphone • RDL/P – redials the last number or provides a pause during dialing. The keyboard is connected to Pins 19 to 26 the MCU (U2). The switches consist of the followings: • BOOST CLARITY POWER – for On/Off the receiver amplifier gain • RINGER ON/OFF – turns On/Off the ringer buzzer They are connected to pins 24 and 21 of MCU. The function LEDs consist of the followings: • MICMUTE (LED2 - Red) – Located under the “MUTE” key. On/Off when microphone is Off/On • INUSE (LED17 – Green; LED6 and LED18 - Red) – Located under the “TALK” key and the handset antenna. On/Off when telephone is Off-hook/On-hook • BOOST (LED17 – RED) – Located under the “TALK” key. On/Off when the receiver amplifer extra gain is On/Off • BACKLIGHT (LED3, LED5, LED7, LED8, LED9, LED10, LED11, LED12, LED13, LED14, LED15, LED16 – Green) – Located under the keyboard. On for a short time when any key is pressed • RINGER (LED6 and LED18 - Red) – Located in the handset antenna. Flashes when the telephone line rings These LEDs are controlled by pins 7, 9, 10, 11 and 12 of MCU. Revision 00 4of 18 3.2 MCU and MCU Interface The controller of the handset is U2. It controls the functions of the handset through the keyboard interface and signals from the base unit. The data to and from the base goes through pin 31 (data from base) and pin 34 (data to base). 3.3 RF Module For operation and frequency see RF module section. It receives the PLL data through pins 5, 6, 7 from MCU pins 1, 43 and 44. The antenna located at the top of the unit and is permanent attached to RF module through a copper wire. 3.4 Compander A compander U5 is used for improving the S/N of transmit and receive audio signals. 3.5 Data Shaper The information which sent from base unit is recovered by the amplifier Q7 and Q9. 3.6 Charge and Control D5, D7, D9, D10, D6, D11, Q5 and ZD1 provide polarity and over-voltage protection during battery charging. The charge signal is detected by pin 29 of the MCU. When the handset is put into the base cradle, a negative pulse is sent to pin 14 of the MCU. 3.7 Low Battery Detector The battery voltage is detected by U4D and the signal is sent to pin 4 of MCU. 3.8 Buzzer Q2 is the buzzer signal amplifier and driven by the MCU pins 2, 32, 33. 3.9 Audio Circuit Speech signal is picked up by the internal microphone M1 and sent to the telephone line through amplifier U4C, the compander U5 and the RF module. The incoming speech is received through the RF module, the compander, the amplifier U4A and U3. When BOOST is On, extra gain is inserted in this audio path. The headset jack is for external speaker and microphone. Revision 00 5of 18 4. Functional Blocks of the Base unit The block diagram of C410 base unit is as shown below.

Base Unit Circuit Block Description 5.1 Power Supply The base unit is powered by an AC adapter (9V dc). The voltage regulator (BU3) regulates the input DC to 5V. This provides power to every part of the unit. 5.2 MCU and MCU Interface The controller of the base is U1 and controls the function of the unit. It communicates with the handset through the RF module. PLL data to the RF module BMD1 is sent through pins 1, 43 and 44. The data between Handset and Base is via the pin 31 (data from handset) and pin 34 (data to handset) through the RF module. The transmitter power is controlled by the signal from pin 35 of MCU. The MCU monitors ring signal from telephone line through the telephone line interface at pin 29. MCU pins 19 to 24 provide DTMF signal through a resistor ladder connected at these pins. The keyboard interface is provided by pins 8 to 12. 5.3 RF Module For operation and frequency see RF module section.. It receives the PLL data through pins 5, 6, 7 from MCU pins 1, 43 and 44. The antenna (~130mm total length) partly located inside the plastic rod at the side the unit is permanent attached to RF module. 5.4 Compander The compander BU2 is used for improving the S/N of the transmit and receive audio signal. 5.5 Data Shaper The information sent from handset unit is recovered by the amplifier BQ4 and BQ5. 5.6 Charge and Control BQ12 detects the handset charging current and sends signal to MCU pin 30. BQ20 detects the 9V supply and sends a negative pulse to MCU pin 14. 5.7 Telephone Line Interface Revision 00 8of 18 BL1, BL2, BF1, BVAR1, B…
