2-2-1. CSP2200B1

— Power Management

Seven low-dropout regulators designed specifically for GSM applications power the terminal and help ensure optimal

system performance and long battery life. A programmable LDO provides support for 1.8V, 3.0V SIMs, while a self-

resetting, electronically fused switch supplies power to external accessories. Ancillary support functions, such as two LED

drivers and two call-alert drivers, aid in reducing both board area and system complexity. A four-wire serial interface

unit(SIU) provides access to control and configuration registers. This interface gives a microprocessor full control of the

CSP2200B1 and enables system designers to maximize both standby and talk times. Error reporting is provided via an

interrupt signal and status register. Supervisory functions. including a reset generator, an input voltage monitor, and a

thermal monitor, support reliable system design. These functions work together to ensure proper system behavior during

start-up or in the event of a fault condition(low microprocessor voltage, insufficient battery energy, or excessive die

temperature).

— Battery Charge Management

A battery charge management block, incorporating an internal PMOS switch, and an 8-bit ADC, provides fast, efficient

charging of single-cell Li-Ion battery. Used in conjunction with a current-limited voltage source, this block safely

conditions near-dead cells and provides the option of having fast-charge and top-off controlled internally or by the system's

microprocessor.

illumination. LED1_DRV is controlled via LED1_[0:2] and can be programmed to sink from 15mA to 60mA in 7.5mA

steps. LED2_DRV is controlled via LED2_[0:2] and can be programmed to sink from 5mA to 40mA in 5mA steps.

Both LED drivers are capable of sinking their maximum output current at a worst-case maximum output voltage of 0.6V.

For efficient use, the LEDs is connected between the battery and the LED_DRV output.

— Vibrator Motor Driver

The vibrator motor driver is a independent voltage regulator to drive a small dc motor that silently alerts the user of an

incoming call. The driver is a 3.3V constant source while sinking up to 140mA and controlled by enable signal of main

chip. For efficient use and safety, the vibrator motor should be connected between the regulator output and the ground.

2-2-2 Connector

— JTAG Connector

Trident has two JTAG ports which are for ARM core and DSP core(DSP16000). So this system has two port connector

for these ports. Pins' initials for ARM core are 'CP_' and pins' initials for DSP core are 'DSP_'.

CP_TDI and DSP_TDI signal are used for input of data. CP_TDO and DSP_TDO signals are used for the output of the

data. CP_TCK and DSP_TCK signals are used for clock because JTAG communication is a synchronous. CP_TMS and

DSP_TMS signals are test mode signals. The difference between these is the RESET_INT signal which is for ARM core

RESET.

— Keypad connector

This is consisted of key interface pins in the trident, KEY_ROW[0~4] and KEY_COL[0~4]. These signals compose the

matrix. Result of matrix informs the key status to key interface in the trident. Some pins are connected to varistor for

ESD protection. And power on/off key is seperated from the matrix.

So power on/off signal is connected with CSP2200 to enable CSP2200.

Nine key LED use the +VBATT supply voltage. These are connected to BACKLIGHT signal in the CSP2200.

This signal enables LEDs with current control.

YMU762MA3 is a LSI for portable telephone that is capable of playing high quality music by utilizing FM synthesizer

and ADPCM decorder that are included in this device.

As a synthesis, YMU762MA3 is equipped 16 voices with different tones. Since the device is capable of simultaneously

generating up to synchronous with the play of the FM synthesizer, various sampled voices can be used as sound effects.

Since the play data of YMU762MA3 are interpreted at anytime through FIFO, the length of the data(playing period) is not

limited, so the device can flexibly support application such as incoming call melody music distribution service. The

hardware sequencer built in this device allows playing of the complex music without giving excessive load to the CPU of

the portable telephones. Moreover, the registers of the FM synthesizer can be operated directly for real time sound

generation, allowing, for example, utilization of various sound effects when using the game software installed in the

portable telephone.

YMU762 includes a speaker amplifier with high ripple removal rate whose maximum output is 550mW (SPVDD=3.6V).

The device is also equipped with conventional function including a vibartor and a circuit for controlling LEDs synchornous

with music.

For the headphone, it is provided with a stereophonic output terminal.

For the purpose of enabling YMU762MA3 to demonstrate its full capabilities, Yamaha purpose to use "SMAF:Synthetic

music Mobile Application Format" as a data distribution format that is compatible with multimedia.

Since the SMAF takes a structure that sets importance on the synchronization between sound and images, various contents

can be written into it including incoming call melody with words that can be used for training karaoke, and commercial

channel that combines texts, images and sounds, and others. The hardware sequencer of YMU762MA3 directly interprets

and plays blocks relevant to synthesis (playing music and reproducing ADPCM with FM synthesizer) that are included in

data distributed in SMAF.

address lines of ARM core and D[0~15], data lines of ARM core are connected to memory, LCD and YMU762.

ICP(Interprocessor Communication Port) controls the communication between ARM core and DSP core.

CSROMEN, CSRAMEN and CS1N to CS4N in the ARM core are connected to each memory. WEN and OEN control the

process of memory. External IRQ(Interrupt ReQuest) signals from each units, such as, YMU, Ear-jack, Ear-mic and

CSP1093, need the compatible process.

Some PPI pins has many special functions. CP_KB[0~9] receive the status from key FPCB and are used for the

communications using data link cable(DEBUG_DTR/RTS/TXD/RXD/CTS/DSR).

battery voltage. And control signals(DSP_INT, DSP_IO and DSP_RWN) for DSP core are used. It enables main LCD with

DSP IP pins.

2-2-7. CSP2200

CSP2200 is integrated the timing and control functions for GSM 2+ mobile application with the ADC and DAC functions,

and power management block. The CSP2200 interfaces to the trident, via a 16-bit parallel interface. It serves as the

interface that connects a DSP to the RF circuitry in a GSM 2+ mobile telephone. DSP can load 148 bits of burst data

into CSP2200’s internal register, and program CSP2200’s event timing and control register with the exact time to send the

burst. When the timing portion of the event timing and control register matches the internal quarter-bit counter and internal

frame counter, the 148 bits in the internal register are GMSK modulated according to GSM 2+ standards. The resulting

phase information is translated into I and Q differential output voltages that can be connected directly to an RF modulator

at the TXOP and TXON pins. The DSP is notified when the transmission is completed. For receiving baseband data, a

DSP can program CSP2200’s event timing and control register with the exact time to start receiving I and Q samples

through TXIP and TXIN pins.


Circuit Description

2-6


When that time is reached, the control portion of the event timing and control register will start the baseband receive

section converting I and Q sample pairs. The samples are stored in a double-buffered register until the register contains 32

sample pairs. CSP2200 then notifies the DSP which has sample time to read the information out before the next 32

sample pairs are stored. The voice band ADC converter issues an interrupt to the DSP whenever it finishes converting a

16-bit PCM word. The DSP then reads the new input sample and simultaneously loads the voice band output DAC

converter with a new PCM output word. The voice band output can be connected directly to a speaker via AOUTAN and

AOUTAP pins and be connected to a Ear-mic speaker via AOUTBN and AOUTBP pins.

There are 7 LDOs which are power sources of microprocessor, LCD, etc. These 7 LDOs output are programmable.
