MSM5238 - 32-DOT LCD COMMON DRIVER

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.

Key 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).

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.
