INTRODUCTION
The S6A0070 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.
The mirror type of S6A0070: S6A1070
FUNCTION
• Character type dot matrix LCD driver & controller
• Internal driver: 16 common and 80 segment signal output
• Easy Interface with a 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 80 characters by using the S6A0065 or S6A2067 externally.
• Various instruction functions
• Built-in automatic power on reset
• Driving method is A-type (line inversion)
FEATURES
• Internal Memory
- Character Generator ROM: 8320bits (192 cha. X 5 x 7 dots) & (32 cha. X 5 x 10 dots)
- Character Generator RAM: 64 x 8 bits (8 cha. X 5 x 7 dots)
- Display Data RAM: 80 × 8 bits for 80 digits (80 characters max.)
• Power Supply Voltage: 2.7 to 5.5 V (VDD)
• LCD Driving Voltage: 3.0 to 10.0 V (VDD - V5)
• Supply Voltage for display: 0 to -5V (V5)
• Programmable duty cycle: 1/8 duty, 1/11 duty or 1/16
• Internal oscillator with an external resistor
• Bare die or bumped chip available

FUNCTION DESCRIPTION
System Interface
This chip has both kinds of interface type with MPU: 4-bit bus and 8-bits 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 DRAM/CGRAM . Target RAM is selected by RAM address setting instruction. Each internal operation, reading from or writing 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 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 - DB7) 1 0 Data Write operation (MPU writes data into DR) 1 1 Data Read operation (MPU reads data into 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.

Address Counter (AC)
The Address Counter (AC) stores DDRAM/CGRAM addresses, transferred from IR. After writing into (reading from) DDRAM/CGRAM. AC is automatically increased (decreased) by 1. When RS = 0 and R/W = 1, AC can be read through ports DB0 - DB6.
Display Data RAM (DDRAM) DDRAM stores display data of maximum 80 x 8 bits (80 characteristics). DDRAM address is set in the address
counter (AC) as a hexadecimal number. (Refer to fig-1).

Figure 1. DDRAM Address
1) 1-line Display In the case of a 1-line display, the address range of DDRAM is 00H - 04H. An Extension driver will be used.
Figure 2 shows the example when a 40-segment extension driver is added.
2) 2-line Display In the case of a 2-line display, the address range of DDRAM is 00H - 27H and 40H - 67H. An Extension driver will
be used. Figure 3 shows the example a 40 segment extension driver is added.
