4 / 41 page Pad Description Pad Name I/O Options Description PA0/BZ PA1/BZ PA2 PA3/PFD PA4~PA7 I/O Wake-up Pull-high or None CMOS or NMOS PA0~PA7 constitute an 8-bit bidirectional input/output port with Schmitt trig- ger input capability. Each pin on port can be configured as a wake-up input by options. PA0~PA3 can be configured as a CMOS output or NMOS in- put/output with or without pull-high resistor by options. PA4~PA7 are always pull-high NMOS input/output. Of the eight bits, PA0~PA1 can be set as I/O pins or buzzer outputs by options. PA3 can be set as an I/O pin or as a PFD output also by options. PB0/INT0 PB1/INT1 PB2/TMR PB3~PB5 I ¾ PB0~PB5 constitute a 6-bit Schmitt trigger input port. Each pin on port are with pull-high resistor. Of the six bits, PB0 and PB1 can be set as input pins or as external interrupt control pins (INT0) and (INT1) respectively, by software application. PB2 can be set as an input pin or as a timer/event counter input pin TMR also by software application. VLCD I ¾ LCD power supply for HT49R30A-1/HT49C30-1. Voltage pump for HT49C30L. V2 I ¾ Voltage pump for HT49R30A-1/HT49C30-1. LCD power supply for HT49C30L. V1,C1,C2 I ¾ Voltage pump COM0~COM2 COM3/SEG18 O 1/2, 1/3or1/4 Duty SEG18 can be set as a segment or as a common output driver for LCD panel by options. COM0~COM2 are outputs for LCD panel plate. SEG0~SEG17 O ¾ LCD driver outputs for LCD panel segments OSC1 OSC2 I O Crystal or RC OSC1 and OSC2 are connected to an RC network or a crystal (by options) for the internal system clock. In the case of RC operation, OSC2 is the output terminal for 1/4 system clock. The system clock may come from the RTC oscillator. If the system clock co- mes from RTC OSC, these two pins can be floating. OSC3 OSC4 I O RTC or System Clock Real time clock oscillators. OSC3 and OSC4 are connected to a 32768Hz crystal oscillator for timing purposes or to a system clock source (depending on the options). VSS ¾¾ Negative power supply, ground VDD ¾¾ Positive power supply RES I ¾ Schmitt trigger reset input, active low Absolute Maximum Ratings Supply Voltage..........................VSS -0.3V to VSS+6.0V* Supply Voltage ........................VSS -0.3V to VSS+2.5V** Storage Temperature ............................ -50°Cto125°C Input Voltage..............................VSS -0.3V to VDD+0.3V Operating Temperature ........................... -40°Cto85°CIOL Total ..............................................................150mA IOH Total ............................................................ -100mA Total Power Dissipation .....................................500mW Note: These are stress ratings only. Stresses exceeding the range specified under ²Absolute Maximum Ratings² may cause substantial damage to the device. Functional operation of this device at other conditions beyond those listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliability. ²*² For HT49R30A-1/HT49C30-1 ²**² For HT49C30L HT49R30A-1/HT49C30-1/HT49C30L Rev. 2.10 4 July 30, 2012 |
