Fabricated in CMOS technology, the device consists of an 80-bit bi-directional shift register, 80-bit level shifter, and 80-bit 4-level driver. The MSM6698 is equipped with 80 LCD output pins. By connecting more than two MSM6698s in series, this LSI is applicable to a wide LCD panel. FEATURES • Logic supply voltage : 2.7 to 5.5 V • LCD drive voltage : 18 to 28 V • Applicable LCD duty : 1/64 to 1/240 • Interface with MSM6599B (80-dot segment driver) • Package: 100-pin plastic QFP (QFP100-P-1420-0.65-K) (Product name: MSM6698GS-K) 1/8 ¡ Semiconductor MSM6698 FUNCTIONAL DESCRIPTION Pin Functional Description • IO1, IO80, SHL IO1 and IO80 are I/O pins of the 80-bit bi-directional shift register. The shift direction can be selected by the SHL pin. Set the SHL pin to "H" or "L" level during power-on. Table 1 gives functions of IO1, IO80, and SHL. Table 1 Shift SHL direction L O1 Æ O80 H O80 Æ O1 I/O Pins IO1 IO80 IO80 IO1 Input, output Function Input The scanning data from the LCD controller LSI is input into IO1 synchronized with the clock pulse. *1 Shift register contents output pin. The scanning data which output was input into IO1 is output from IO80 with 80-bit delay, synchronized with the clock pulse. Input The scanning data from the LCD controller LSI is input into IO80 synchronized with the clock pulse. *1 Shift register contents output pin. The scanning data which output was input into IO80 is output from IO1 with 80-bit delay, synchronized with the clock pulse. *1 The combination of the scanning data, IO1 or IO80, and the LCD driving output, O1 - O80, is shown in the table below. Scanning data "H" "L" LCD driving output Select level (V1, VEE) Non-Select level (V2, V5) 6/8 6 Page
