10 / 101 page TC9325F 2002-05-14 10 Pin No. Symbol Pin Name Function and Operation Remarks 94 XOUT2 95 XIN2 75 kHz crystal oscillator pins 97 XOUT1 98 XIN1 4.5 MHz crystal oscillator pins Crystal oscillator pins. Connect a 4.5 MHz crystal (Ci = Co = 30 pF typ.) to XIN1 and XOUT1 and a 75 kHz crystal (Ci = Co = 30 pF typ.) to XIN2 and XOUT2. Two different types of crystal resonators (4.5 MHz and 75 kHz) can be connected, or simply connect one (4.5 MHz or 75 kHz). Note that if a 75 kHz crystal only is connected, XIN1 must be fixed to GND level. If both 4.5 MHz and 75 kHz crystal oscillators are connected, after a reset the CPU operates on the 4.5 MHz crystal oscillator clock. The clock can be readily switched by software between the CPU operating clock and the peripheral clock. Oscillation stops during execution of the CKSTP instruction. 100 VEE LCD driver bias voltage output pin This is the bias voltage output pin for the LCD driver. 76 96 VDD 41 55 72 93 GND 39 VDD1 99 GND1 Power supply pins Pins used for supplying power. The pins supply VDD = 3.0 to 3.6 V. In backup state (when execution of the CKSTP instruction), current dissipation becomes low (10 µA max), dropping the power supply voltage to 2.0 V. If 3.0 V or more is applied to these pins when the voltage is 0 V, a system reset is applied to the device and the program starts from address 0 (power-on reset). Note: To operate the power-on reset, allow 10 to 100 ms while the device power supply voltage rises. 56 VDD2 Power supply pins For I/O Port4,5 Pins used for supplying power for I/O port 4,5.The pins supply VDD = VDD to 5.5 V. 72 93 NC No connection No connection VDD RfXT1 ROUT1 XIN1 XOUT1 VDD RfXT2 ROUT2 XIN2 XOUT2 VDD GND VDD2 |
