This chip includes 80-bits shift register, 80 bits data latch and 80 bits level driver. A LCD RAM inside can be mapping to LCD signal. It converts RAM data to parallel data and output waveform to LCD. FEATURES (1) Supply power: 2.5~5.5V (2) LCD drive voltage: 3.6 to15V (3) Internal RAM: 2.5k x 4 bits (4) RAM can be controlled by eight signals including four bits data bus. (5) Duty: 1/32, 1/48, 1/64, 1/80 (6) Build in DC/DC converter: double, triple, quad and five times. (7) Modularized function: connect to another 83040B to extent LCD matrix (8) One DC converter enabled and other 83040B can share with this. (9) Internal regulator output for DC/DC converter controlled by control register. (10) Chip form (EM83040BH), 128 pin package (14mm x 20mm EM83040BAQ), 160 pin package (EM83040BBQ) (11) Bias: 1/5 (32 COMMON), 1/7 (48 COMMON), 1/9 (64 and 80 COMMON) fixed by internal circuit. (12) Internal RC clock about 250 KHz. APPLICATION (1) Data Bank (2) LCD toy (3) Education computer |
