15 / 89 page ![]() GMS81C1102 / GMS81C1202 12 Jan. 2002 ver 2.0 • (VDD=2.2~6.0V, VSS=0V, fXIN =1MHz~4.2MHz, TA=-20 °°°°C~+85°°°°C) Parameter Symbol Pin1 1. RC0, RC1, RB1 and RB3 pins are applied for GMS81C1202 only. Test Condition Specification Unit Min Typ2 2. Data in “Typ” column is at 3V, 25 °C unless otherwise stated. These parameters are for design guidance only and are not tested. Max Input High Voltage VIH1 XIN VDD=2.2~6.0V 0.8VDD VDD V VIH2 RESET 0.9VDD VDD VIH3 RB2, RB3 0.8VDD VDD VIH4 RA,RB0,RB1,RB4,RC 0.7VDD VDD Input Low Voltage VIL1 XIN VDD=2.2~6.0V 0 0.2VDD V VIL2 RESET 0 0.1VDD VIL3 RB2, RB3 0 0.2VDD VIL4 RA,RB0,RB1,RB4,RC 0 0.3VDD Output High Voltage VOH RA, RB, RC VDD = 3V, IOH = -2mA 2.5 V Output Low Voltage VOL RA, RB, RC VDD = 3V, IOL= 5mA 0.7 V Input Leakage Current IIL RESET,RA,RB,RC VIN = VSS~VDD ±5 uA IIL XIN ±15 Input Pull-up Current IPU RB2, RB33 3. This parameter is valid when the bit PUPSELx is selected and set the Input mode or Interrupt Input Function. VDD = 3V, VIN = VSS -100 -60 -40 uA Power Fail Detect Voltage VPFD VDD 23.5 4 V Normal Operating Current IDD VDD VDD = 3V, fXIN = 4MHz 23 mA Wake-up Timer Mode Current IWKUP VDD VDD = 3V, fXIN = 4MHz 0.5 1 mA RC-oscillated Watchdog Timer Mode Current IRCWDT VDD VDD = 3V, fXIN = 4MHz 0.3 0.6 mA STOP Mode Current ISTOP VDD VDD = 3V 0.2 1 uA Hysteresis VT+ ~ VT- RESET, RB2, RB3 0.5 V Internal RC Oscillation Period ( RC-WDT CLK ) TRCWDT XOUT VDD = 3V, fXIN = 4MHz 200 400 uS RC Oscillation Frequency ( System CLK ) fRCOSC4 4. This parameter is measured in XOUT pin, and measured frequency is must be 4times to be internal system clock because of this XOUT signal is divided by 4 of system clock. XOUT VDD = 3V, R = 47K Ω, C=7pF 200 300 kHz |
