MSM5238

E2B0027-27-Y2 ¡ Semiconductor ¡ Semiconductor MSM5238 32-DOT LCD COMMON DRIVER This version: Nov. 1997 MSM5238 Previous version: Mar. 1996 GENERAL DESCRIPTION The MSM5238 is a dot matrix LCD common driver LSI which is fabricated using low power CMOS metal gate technology. The scanning signal in one matrix display frame can be divided into up to 1/32 duty. This LSI consists of 32-bit shift register, 32-bit level shifter and 32-bit 4-level driver. This LSI can drive a variety of LCD panels because the bias voltage, which determines the LCD driving voltage, can be optionally supplied from an external source. FEATURES Supply voltage : 3 to 7V LCD driving voltage : 3 to 16V Applicable LCD duty : 1/32 to 1/64 (1/64 duty is available when MSM5238s are cascade-connected) Bias voltage can be supplied externally. Applicable segment driver: MSM5839B/C (40 outputs) Package options: 44-pin plastic QFP (QFP44-P-910-0.80-K) (Product name: MSM5238GS-K) 44-pin plastic QFP (QFP44-P-910-0.80-L2) (Product name: MSM5238GS-L2) 44-pin plastic QFP (QFP44-P-910-0.80-2K) (Product name: MSM5238GS-2K) 1/12 ¡ Semiconductor MSM5238 BLOCK DIAGRAM O1 VDD V1 V2 V3 VEE(V4) O32 32-Bit 4-Level Driver VDD VEE 32-Bit Level Shifter VDD DF VSS DI CP 32-Bit Shift Register VSS DO 2/12 ¡ Semiconductor MSM5238 PIN CONFIGURATION (TOP VIEW) 39 VDD 40 VSS (Top view) 43 NC 41 CP 42 DF 44 DI 35 VEE(V4) O1 O2 O3 O4 O5 O6 O7 O8 O9 O10 O11 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 ...
