Chapter 1
THEORY OF OPERATION
1.0 Overview
This Chapter provides a detailed theory of operation for the power distribution and controller circuits
in the radio. The components for these circuits are contained on the Main Board. Refer to the RF
sections of this manual for the component location details and the parts lists for these circuits.
2.0 Radio Power Distribution
Figure 1-1 illustrates the DC distribution throughout the radio board. A 7.5V battery (BATT 7.5V)
supplies power directly to the electronic on/off control as UNSWB+. When the radio is turned on,
MECH_SWB+ (on/off/volume control) will trigger the electronic on/off control (momentary-on path),
then SWB+ is distributed as shown in Figure1-1. Vdda from 3.3V Vdda regulator will then supply the
microprocessor. Data is then sent to ASFIC_CMP to turn on GCB4(DAC). GCB4 will take over the
momentary-on path within 12ms. SWB+ will continue to support the whole board until the radio is
turned off.
Radio will be turned-off on two conditions;
1. MECH_SWB+ turned off
2. Low battery
When low battery level is detected by the microprocessor through both conditions above, it will store
the radio personality data to EEPROM before turning off.

1-2 THEORY OF OPERATION
3.0 Controller Circuits
3.1 Controller Architecture
The controller board is the central interface between the various subsystems of the radio. It is
separated into MCU digital and audio/signalling architectures as shown in Figure 1-2.
Figure 1-2 Controller Block Diagram
3.2 MCU Digital Architecture
( Refer to Figure 1-2, the Microprocessor and the Memory schematic diagrams )
The digital architecture portion consists of a microcontroller and associated EEPROM, RAM, and
ROM memories. The architecture is commonly used for both low-tier and high-tier products and also
includes conventional and trunking portables. Combinations of different size RAM and ROM are
available to support various application software. RAM supports 8KB and 32KB sizes. ROM
supports 128KB, 256KB, and 512KB sizes. Table 1-1 shows the ROM, RAM and EEPROM
requirements for different applications.

3.3 Real Time Clock
( Refer to Figure 1-3 and the Microprocessor schematic diagram )
Radios with displays support a Real Time Clock (RTC) module for purposes of message time
stamping and time keeping. The RTC module resides in the microcontroller.The clock uses a back-
up Lithium Ion battery for operating power when the primary battery is removed.
3.3.1 Circuit Description
The RTC module circuit, shown in Figure 1-3, is powered by the ModB/Vstby pin and PI6/PI7 from
the crystal oscillator circuit. A clock frequency of 38.4kHz from a crystal oscillator provides the
reference signal which is divided down to 1 Hz in the processor.
Figure 1-3 RTC Circuit
As the RTC module is powered separately from the processor Vdd, the RTC is kept active through
the ModB / Vstby pin which provides the Lithium battery back-up power when the radio is switched
off.

BOOT_CTRL

1-4 THEORY OF OPERATION
A MOSFET Q416 switches in the LiO supply when Vdd is removed. Q416 also provides isolation
from BOOT_CTRL function in the event of radio program flashing. The 3.3V regulator charges the
Lithium battery.
3.4 ModB/Vstby Supply
The supply to the ModB/Vstby pin varies depending on the conditions listed in Table 1-2.
3.5 Audio/Signaling Architecture
( Refer to Figure 1-2 and the ASFIC/ON_OFF and Audio Power Amplifier schematic diagrams )
The audio/signalling/filter/companding IC (ASFIC_CMP) and the audio power amplifier, shown in
Figure 1-2, form the main components of the audio/signalling architecture section of the controller
board. Inputs include a 16.8 MHz clock from the synthesizer, recovered audio and squelch, MCU
control signals, and external or internal microphones. Outputs include a microprocessor clock (uP),
modulator output to the synthesizer, and amplified audio signals to an internal or external speaker.
