Semiconductor 5 7-Dot Character 16-Digit Display Controller/Driver
This version:MSC7128-XX Nov. 1997 Previous version: Jul. 1996
GENERAL DESCRIPTION
The MSC7128-XX is a general purpose display controller for vacuum fluorescent display tube. The MSC7128-XX drives displays with up to 35 anodes (dots) and up to 16 grids (characters) plus a cursor. The controller accepts command and display data input words on a clocked serial input line. Commands control the on/off duty cycle, starting character position, number of characters to display and display modes (PLA mode and Lamp Test mode). An internal PLA-type character generator provides character decoding and dot pattern generation for the full 128 characters. A 35 128-bit PLA (ROM) code is programmable.

FUNCTIONAL DESCRIPTION
Data Transfer Method and Command Write Method A display control command or data is written by the 8-bit serial transfer method. The figure below shows the write timing. When the CS pin is Low, data can be transferred. Data of 8 bits in length is input to the DA pin sequentially starting with the LSB. (LSB first) Data is shifted at the rising edge of a shift clock pulse which is input to the CP pin as shown in the figure below. When 8-bit data is entered, an inner LOAD signal is automatically generated, and data is written into the registers and RAM. Therefore, there is no need to input an external LOAD signal. If the CS pin is changed from Low to High, the serial transfer is inhibited, and data, which is entered after the CS pin is changed from High to Low, is recognized in units of 8 bits. The first 8 bits become the first byte, and the second 8 bits become the second byte and the next 8 bits become either the first byte or the second byte depending on the selected command.

Semiconductor Command Description * Address set command
MSC7128-XX
When the code of a display character is to be set, this command is used to specify the display location (digit number) of the character. The relation between the digit number X and common outputs COM1 to COM16 is as follows:
X 0 1 15 COM Input COM1 COM2 COM16

Digit number (0 to 15)
* Character code set command This command is used to specify the character to be displayed in the digit place specified by the Address Set command. Bits 0 to 6 of the second byte are used to specify the character code, and bit 7 is used to specify "Yes" or "No" of cursor display. Command format

An automatic address increment function is built in. To write multidigit display character codes, issue the Address Set command. To transfer the second and later digit display character codes, the first byte (operation code) of the Character Code command is not required. Input the second byte. When this command is executed, 8-bit data for the second byte and later bytes, which is provided before the CS pin is turned High, is all treated as display character data.

Semiconductor Display Duty Set Command
MSC7128-XX
Assuming the original oscillation cycle as T, the time allocated to 1-digit display is 64T. The actual display time may be specified as 0 to 60T in increments of 4T. Assuming the number of display digits as n and the parameter provided by the Display Duty Set command as DC, the resultant display duty cycle ratio is as follows: 4 (DC) 64n = (DC) 16n
Command format
LSB 1 0 1 0 X X X X LSB X X X X DG3 DG2 DG1 DG0 2nd byte 1st byte
DC value (0 to 15)
Lamp Test Command This command is used to set the All-Segment Display mode. If this occurs, the 36 segments for each digit to be displayed are put into the ON state. The number of display digits and the display duty cycle depend on the contents of the digit count register and of the duty register. The contents of the internal RAM are not affected by this command. When the command is released, the original display appears once again. Command format
LSB 1 1 0 0 X X X X LSB X X X X X X X LT 2nd byte 0: Normal mode 1: Lamp test mode 1st byte
16/27
Semiconductor Power On Reset Operation Operations when the RESET pin is Low are as follows: a. All segment driver outputs are Low. b. All grid driver outputs are Low. c. The number of display digits is set to 16. d. The display duty cycle is set to 0.

Test Step and Test Count These pins are used for inspection before shipment, and should not be used by the user. When this IC is mounted, leave them open or connect to VSS. If they are connected to other pins, a malfunction may be caused.

Notes for Mounting the Surface Mount Type Package The SOP, QFP, TSOP, SOJ, QFJ (PLCC), SHP and BGA are surface mount type packages, which are very susceptible to heat in reflow mounting and humidity absorbed in storage. Therefore, before you perform reflow mounting, contact Oki's responsible sales person for the product name, package name, pin number, package code and desired mounting conditions (reflow method, temperature and times).

Notes for Mounting the Surface Mount Type Package The SOP, QFP, TSOP, SOJ, QFJ (PLCC), SHP and BGA are surface mount type packages, which are very susceptible to heat in reflow mounting and humidity absorbed in storage. Therefore, before you perform reflow mounting, contact Oki's responsible sales person for the product name, package name, pin number, package code and desired mounting conditions (reflow method, temperature and times).
