KS0070B
16COM / 80SEG DRIVER & CONTROLLER FOR DOT MATRIX LCD
INTRODUCTION
KS0070B is a dot matrix LCD driver & controller LSI which is fabricated by low power CMOS technology.
It is capable of displaying 1 or 2 lines with the 5×7 format or 1 line with the 5×10 dots format.
FUNCTIONS
• Character type dot matrix LCD driver & controller
• Internal driver: 16 common and 80 segment signal output
• Easy interface with 4-bit or 8-bit MPU
• Display character pattern: 5×7 dots format (192 kinds) & 5×10 dots format (32 kinds)
• The special character pattern is directly programmable by the character generator RAM.
• A customer character pattern is programmable by mask option.
• It can drive a maximum of 80 characters by using the KS0065B or KS0063B externally.
• Various instruction functions
• Built-in automatic power on reset
• Driving method is A-type (Line inversion)
FEATURES

16COM / 80SEG DRIVER & CONTROLLER FOR DOT MATRIX LCD
FUNCTION DESCRIPTION
System Interface
This chip has both kinds of interface type with MPU: 4-bit bus and 8-bit bus.
4-bit bus and 8-bit bus are selected by the DL bit in the instruction register.
During read or write operation, two 8-bit registers are used. One is the data register (DR), and the other is the
instruction register (IR).
The data register (DR) is used as a temporary data storage place for being written into or read from DDRAM/
CGRAM. Target RAM is selected by RAM address setting instruction. Each internal operation, reading from or writ-
ing into RAM, is done automatically.
After MPU reads DR data, the data in the next DDRAM/CGRAM address is transferred into DR automatically.
Also, after MPU writes data to DR, the data in DR is transferred into DDRAM/CGRAM
automatically.
The Instruction register (IR) is used only to store instruction codes transferred from MPU. MPU cannot use it to
read instruction data.
To select a register, use RS input pin in 4-bit/8-bit bus mode.
Table 1. Various Kinds of Operations According to RS and R/W bits.
RS R/W
Operation
0 0 Instruction Write operation (MPU writes Instruction code into IR)
0 1 Read Busy flag (DB7) and address counter (DB0 ~ DB6)
1 0 Data Write operation (MPU writes data into DR)
1 1 Data Read operation (MPU reads data from DR)
Busy Flag (BF)
When BF = "1", it indicates that the internal operation is being processed. So during this time the next instruction
cannot be accepted. BF can be read, when RS = "0" and R/W = "1"
(Read Instruction Operation), through DB7 port.
Before executing the next instruction, be sure that BF is not "1".
