Semiconductor MSM5839C
40-DOT SEGMENT DRIVER
This version: MSM5839C Nov. 1997 Previous version: Mar. 1996
GENERAL DESCRIPTION
The MSM5839C is a dot matrix LCD segment driver LSI which is fabricated using low power CMOS metal gate technology. This LSI consists of two 20-bit shift registers, two 20-bit latches, a 40-bit level shifter and a 40-bit 4-level driver. It converts serial data, which is received from LCD controller LSI, into parallel data and outputs LCD driving waveform to the LCD panel. Expansion of display can easily be made by increasing the number of characters and character patterns. This LSI can drive a variety of LCD panels because the bias voltage, which determines an LCD driving voltage, can be optionally supplied from the external source.
FEATURES
* Supply voltage : 4.5 to 5.5V * LCD driving voltage : 4 to 11V * Applicable LCD duty : 1/3 to 1/64 * Bias voltage can be supplied externally. * Applicable commomn driver: MSM5238 (32 outputs) * Package options: 56-pin plastic QFP (QFP56-P-910-0.65-K) (Product name: MSM5839C GS-K) 56-pin plastic QFP (QFP56-P-910-0.65-L2) (Product name: MSM5839C GS-L2)

FUNCTIONAL DESCRIPTION
Pin Functional Description * DI1 The data input pin for the 20-bit shift register (from 1st to 20th bit). The display data is input to the data input pin in synchronization with a clock pulse. * CP Clock pulse input pin for the two 20-bit shift registers. The data is shifted in the two 20-bit shift registers at the falling edge of the clock pulse. Data setup time (tSETUP) and data hold time (tHOLD) are required between DI1, DI21 and CP. * DO20 The 20th output bit of the shift register. The data which is input from DI1 is clocked out with a delay of the number of bits of the shift register (20). A 40-bit shift register can be configured by connecting the output of this pin to DI21 pin. * DI21 The data input pin for the 20-bit shift register (from 21st to 40th bit). Connecting the DO20 pin and this pin allows the device to be used as a 40-bit shift register. * DO40 The 40th output bit of the shift register. The data which is input from DI1 is clocked out with a delay of the number of the bits of the shift register. When increasing the number of characters, this pin is used to cascade connect the next MSM5839C. * DF Alternate signal input pin for LCD driving waveform. * VDD(V1), VSS Supply voltage pins. VDD should be 4.5 to 5.5V. VSS is a ground pin (VSS = 0V). * V2, V3, VEE(V4) Bias supply voltage pins to drive the LCD. Bias voltage is supplied from an external source. * LOAD The signal for latching the shift register contents is input from this pin. When LOAD pin is set at "H", the shift register contents are transferred to the 40-bit 4-level driver. When LOAD pin is set at "L", the last display output data (O1 to O40), which was transferred when LOAD pin was at "H", is held.

* O1 to O40 Display data output pins which correspond to each data bit in the latch. One of VDD, V2, V3 or VEE (V4) is selected as a display driving voltage source based on the combination of latched data level and DF signal. Refer to the Truth Table below. These pins should be connected to the SEGMENT side of the LCD panel.
