Function Descriptions
1. Power supply control section
(1) Reference voltage circuit The reference voltage circuit generates a temperature- compensated, stable voltage ( 1.26 V). The generated reference voltage is used as the power supply control section reference voltage or bias. (2) Series regulator section A 4 - channel series regulator incorporating a low - saturation output transistor is used. All four channels provide an output voltage of 3.0 V. Their characteristics are described below. REG1 is suitable for a microcontroller power supply because it is connected to a power - on reset circuit. It is controlled by the ON/OFF switch section. ON/OFF control of REG2 and REG3 is exercised independently by the CTL2 and CTL3 pins while REG1 is ON. REG4 operates at all times and is therefore suitable for data backup. REGs 1 through 4 incorporate an overcurrent - protection circuit (REG1 to REG3 - 100 mA, REG4 - 25 mA). (3) Battery backup section When the main battery is installed, the series regulator recharges a button - type lithium secondary battery, which is often used to provide backup for clocks and memory. When the main battery is not installed, the backup battery supplies power to clocks and the battery via a built - in diode. Since the recharging series regulator is set at 3.18 V, this battery backup section is suitable for manganese and lithium batteries. (4) ON/OFF switch section When a time - setup capacitance and resistance are connected to the CT1 pin, the ON1 pin makes it possible to set the power supply button activation time. This feature prevents turning ON a mobile telephone accidentally. The ON2 and OFF pins provide a method of exercising direct ON/OFF control of the regulator. ON time setting calculation formula: TON - CT1 x RT1 x ln (1 - 1.26V/VCC2) (5) Momentary power - loss function and power - restoration section When a time - setup capacitance and resistance are connected to the CT3 pin, a momentary Vcc loss, which may be caused by battery replacement, etc., will be detected so as to deliver output to the TOUT pin. At power restoration, the operating state before the momentary power loss is recovered. After a momentary power loss, the CLR pin resets the prevailing state so that the momentary power - loss detection circuit retains the latch circuit state. Momentary power - loss detection time calculation formula: TOFF - CT3 x RT3 x ln (1 - (2.3V - 0.27V)/2.3V)

2. Speaker amplifier section
A BTL - output type amplifier is used to drive the speaker directly. The typical output power is as high as 90 mW (at 32 W), and the SB pin provides ON/OFF control. The CHOICE pin controls earphone selection.
3. Sounder section
This section incorporates three low - saturation output transistors for driving the buzzer. IN1, IN2, and IN3 are used to select the output transistor.
4. Voltage monitoring section
This section incorporates the REG1 output voltage detection function and watchdog timer function. It outputs a reset signal to the RESET pin. Further, the detection time varies with the capacitance connected to the CTP and CTW pins.

DESCRIPTION OF OPERATION
(The numbers in the timing diagram correlate to the numbers (1) to (13) below.) (1) When the REG1 output voltage (OUT1) is about 0.8 V (VCCL), the reset signal is output. (2) When OUT1 reaches a level higher than the detection voltage (VSH), the power - on reset/hold time setup capacitor (CTP) begins to charge. The VSH value is 2.81 V. (3) When the power - on reset/hold time setup pin (CTP) voltage rises above the threshold level (Vth), the reset clears (RESET pin voltage changes from L level to H level). The Vth value is about 1.9 V. The power - on reset/hold time (tPR) is expressed by the following equation. Also, the watchdog timer monitoring time setup capacitor (CTW) begins to charge. tPR [ms] A x CTP [mF] A 700 (4) When the watchdog timer monitoring time setup pin (CTW) voltage reaches the Hi level (VH), the CTW changes from the charged state to the discharged state. The VH value is about the reference voltage of 1.24 V. (5) When a clock pulse input is applied to the clock pin (CK) and then the next clock pulse input is applied (positive edge trigger) to the CK pin during a CTW discharge, switching from the discharged state to the charged state occurs. (6) If a clock pulse input is not delivered to the clock pin (CK) within the watchdog timer monitoring time (tWD), the CTW pin voltage falls below the Lo level (VL) so the reset signal is output (RESET pin voltage changes from H level to the L level). The VL value is about 0.24 V. The watchdog timer monitoring time (tWD) is expressed by the following equation. tWD [ms] B x CTW [mF] B 1600 (7) When the CTP is recharged to raise the CTP pin voltage above Vth, the reset clears, allowing the watchdog timer to start running. The watchdog timer monitoring reset time (tWR) is expressed by the following equation. tWR [ms] D x CTP [mF] B 50 (8) When the OUT1 drops below the fall period detection voltage (VSL), the CTP pin voltage falls so that the reset signal is output (RESET pin voltage changes from H level to the L level). The VSL value is about 2.75 V. (9) When the OUT1 rises above VSH, CTP charging starts. (10) When the CTP pin voltage rises above Vth, the reset clears, causing the watchdog timer to start running. (11) When the inhibit signal is input (Hi level), the watchdog timer operation is forcibly stopped. In this case, only the watchdog timer stops and the OUT1 monitoring operations ((8) to (10)) are performed. If the inhibit input does not clear, the watchdog timer does not operate. (12) When the inhibit input clears (becomes Lo level), the watchdog timer begins to operate. (13) When the REG1 output turns OFF and OUT1 falls below VSL, the reset signal is output.

USAGE PRECAUTIONS
1. Device settings must not exceed the maximum ratings. Usage under conditions exceeding absolute maximum ratings may permanently damage LSI devices. Note also that in normal operation usage within recommended operating conditions is preferred, and that the reliability of LSI devices may be adversely affected when used outside these conditions. 2. Devices should be used within recommended operating conditions. Recommended operating conditions are recommended values within which the LSI device is warranted to operate normally. Rated values of electrical characteristics are warranted within the range of recommended operating conditions and within the conditions listed in the condition column for each parameter. 3. The PC board ground line must be designed by taking the common impedance. 4. Guard against static electricity. The semiconductor containers must be protected against static electricity or made of conductive materials. When storing or transporting a component - mounted PC board, place it in a conductive bag or container. Ensure that the workbenches, tools, and measuring instruments are grounded. Workers must be grounded via a series resistance of 250 kW to 1 MW.
