AX6120

The AX6120 is a kind of dot matrix LCD driver. The device is designed for the display pf characters and graphics. The driver generates LCD drive signals derived from bit mapped data stored in an internal RAM. The device incorporates innovative circuit design strategies to achieve very low power dissipation at a wide range of operating voltages.

There are some features AX6120 as follows: (1)fast 8-bit MPU interface compatible with 80- and 68- family microcomputers; (2)rich command set; (3)80 (segment+common) drive sets; (4)low power: 30W at 2 kHz external clock; (5)wide range of supply voltages: VDD-VSS: -2.4 to -7.0 V; VDD-V5: -3.5 to -13.0 V; (6)low power CMOS; (7)packages: 100-pin QFP, Al pad chip and Au bump pad chip.

What comes next is about the absolute maximum ratings AX6120: (1)supply voltage, VSS: -8.0 to +0.3 V; (2)supply voltage, V5: -16.5 to +0.3 V; (3)supply voltage, V1, V4, V2, V3: V5 to +0.3 V; (4)input voltage, VIN: VSS-0.3 to +0.3 V; (5)output voltage, VO: VSS-0.3 to +0.3 V; (6)power dissipation, PD: 250 mW; (7)operating temperature, Topr: -30 to +85; (8)storage temperature, Topr: -65 to +150; (9)soldering temperature (10 s): 260.

The following is about the DC characteristics AX6120 (Ta=-20 to 75, VDD=0 V, unless stated otherwise): (1)operating voltage, VSS: recommended: -5.5 V min, -5 V typ and -4.5 V max at VSS pin; allowable: -7 V min and -3 V max at VSS pin; (2)operating voltage, V5: recommended: -12 V min and -3.5 V max; (3)operating voltage, V1, V2: allowable: 0.6*V5 V min and VDD V max at pins V1, V2; (4)operating voltage, V3, V4: allowable: V5 V min and 0.4*V5 V max at pins V3, V4; (5)high level input voltage: VIHT: VSS+2.0 V min and VDD V max; VIHC: 0.2*VSS V min and VDD V max; (6)low level input voltage: VLHT: VSS V min and VSS+0.8 V max; VLHC: VSS V min and 0.8*VSS V max.
