3 / 16 page HC908LJ12AD/D MC68HLC908LJ12 Addendum to MC68HC908LJ12 Technical Data Input current IRQ IIN —— ± 1 µA Capacitance Ports (as input or output) COUT CIN — — — — 12 8 pF POR re-arm voltage(7) VPOR 0— 100 mV POR rise-time ramp rate(8) RPOR 0.02 — — V/ms Monitor mode entry voltage (at IRQ pin) VHI 1.5 × V DD — 2 × V DD V Pullup resistors(9) PTA0–PTA3, PTD4–PTD7 configured as KBI0–KBI7 RST, IRQ RPU1 RPU2 — — 25 27 — — k Ω k Ω 1. VDD = 2.4 to 2.7 Vdc, VSS = 0 Vdc, TA = TL to TH, unless otherwise noted. 2. Typical values reflect average measurements at midpoint of voltage range, 25 °C only. 3. Run (operating) IDD measured using external square wave clock source. All inputs 0.2 V from rail. No dc loads. Less than 100 pF on all outputs. CL = 20 pF on OSC2. All ports configured as inputs. OSC2 capacitance linearly affects run IDD. 4. Wait IDD measured using external square wave clock source. All inputs 0.2 V from rail. No dc loads. Less than 100 pF on all outputs. CL = 20 pF on OSC2. All ports configured as inputs. OSC2 capacitance linearly affects wait IDD. 5. The 8kHz clock is from a 32kHz clock input at OSC1, for the driving the RTC. 6. LCD driver configured for low current mode. 7. Maximum is highest voltage that POR is guaranteed. 8. If minimum VDD is not reached before the internal POR reset is released, RST must be driven low externally until minimum VDD is reached. 9. RPU1 and RPU2 are measured at VDD = 2.6V. Table 2. DC Electrical Characteristics (2.4 to 2.7V) (Continued) Characteristic(1) Symbol Min Typ(2) Max Unit Table 3. DC Electrical Characteristics (2.7 to 3.3V) Characteristic(1) Symbol Min Typ(2) Max Unit Output high voltage (ILOAD = –1.0 mA) All ports VOH VDD–0.4 —— V Output low voltage (ILOAD = 0.8mA) All ports (ILOAD = 4.0 mA) PTB2–PTB5 (ILOAD = 10.0 mA) PTB0/TxD–PTB1 VOL —— 0.4 V Input high voltage All ports, RST, IRQ, OSC1 VIH 0.7 × V DD — VDD V Input low voltage All ports, RST, IRQ, OSC1 VIL VSS — 0.3 × V DD V Freescale Semiconductor, Inc.
