11 / 71 page  EM78468 8-BIT Microcontroller Product Specification (V1.1) 04.11.2005 • 7 (This specification is subject to change without further notice) Table 1 (a) Pin Description for Package of QFP64 and LQFP64 Pin Pin Number I/O type Description VDD 29 I * Power supply pin GND 26 I * System ground pin R-OSCI 27 I * In crystal mode: crystal input * In RC mode: resistor pull high. * In PLL mode: connect 0.01μF capacitance to GND * Connect 0.01μF capacitor to GND and code option select PLL mode when high oscillator is not use. OSCO 28 O * In crystal mode: crystal output * In RC mode: instruction clock output Xin 30 I * In crystal mode:Input pin for sub-oscillator. Connect to a 32.768KHz crystal * RC mode: this pin is connected with a resistor to high level. Xout 31 O * In crystal: Connect to a 32.768KHz crystal * In RC mode: instruction clock output /RESET 25 I * Low active. If set as /RESET and remains at logic low, the devices will be reset P5.4/INT0 32 I/O * General purpose I/O pin. /external interrupt. * INT0 interruption source can be set to falling or rising edge by IOC71 register bit 7 (INT_EDGE). * Wake up from sleep mode and idle mode when the pin status changes. P5.5/INT1 33 I/O * General purpose I/O pin. /external interrupt. * Interruption source is a falling edge signal. * Wake up from sleep mode and idle mode when the pin status changes. P5.6/TCC 34 I/O * General purpose I/O/ external counter input * This pin works in normal/green/idle mode. P5.7/IROUT 37 I/O * General purpose I/O pin or IR/PWM mode output pin, * Capable of sinking 18mA/5V. P6.0 ~ P6.7 38~45 I/O * General purpose I/O pin. * Pull-high, pull-low and open drain function support. * All pins can wake up from sleep and idle modes when the pin status changes. COM3~0 17~20 O * LCD common output pin. SEG0~SEG15 16~1 O * LCD segment output pin. SEG16/P7.0 ~ SEG23/P7.7 64 ~ 57 O/(I/O) * LCD segment output pin. Can be shared with general purposes I/O pin SEG24/P8.0 ~ SEG30/P8.6 SEG31/P8.7 56 ~ 50 46 O/(I/O) * LCD segment output pin. Can be shared with general I/O pin * For general purpose I/O use, can wake up from sleep mode and idle mode when the pin status changes. * For general purposes I/O use, supports pull-high function. VB 21 O * Connect capacitors for LCD bias voltage VA 22 O * Connect capacitors for LCD bias voltage VLCD2 23 O * One of LCD bias voltage VLCD3 24 O * One of LCD bias voltage NC 35~36 47~49 |
