132 x 33 Dot Matrix LCD Controller/Driver
1. INTRODUCTION
ST7573 is a driver & controller LSI for graphic dot-matrix liquid crystal display systems. ST7573 contains 132 segment and
33 common driver circuits. This chip is connected directly to a microprocessor, accepts 3-line, 4-line serial peripheral
interface (SPI) or 8-bit parallel interface, display data can stores in an on-chip Display Data RAM (DDRAM) of 132 x 33 bits.
It performs Display Data RAM read/write operation with no external operating clock to minimize power consumption. In
addition, because it contains power supply circuits to drive liquid crystal, it is possible to make a display system with the
fewest components.

7. FUNCTIONS DESCRIPTION
MICROPROCESSOR INTERFACE
Chip Select Input
The CSB pin is used for chip selection. ST7573 can interface with an MPU when CSB is "L". When CSB is “H”, the control
pins (A0, /RD and /WR) are disabled and D0 to D7 are set to be high impedance. If using serial interface, the internal shift
register and the counter are reset when CSB=”H”.
Parallel / Serial Interface
ST7573 has five types of interface to communicate with an MPU, which are three serial and two parallel interfaces. The
parallel or serial interface is determined by PS[2:0] pin as shown below.
Table 1 Parallel/Serial Interface Selection
PS2 PS1 PS0 CSB A0
State
“L” “L” “L” CSB A0
4 Pin-SPI MPU interface
“H” “L” “L” CSB "H"
3 Pin-SPI MPU interface
“L” “H” “L” CSB A0
8080-series parallel MPU interface
“H” “H” “L” CSB A0
6800-series parallel MPU interface
Parallel Interface
The 8-bit bi-directional data bus is used in parallel interface and the type of MPU is selected by PS[2:0] as shown in Table 2.
The type of data transfer is determined by A0, ERD and RWR as shown in Table 3.

NOTE: When ERD pin is always pulled high in 6800-series interface, the CSB can be used as enable signal. In this case,
interface data is latched at the rising edge of CSB and the access type is determined by A0, RWR as 6800-series mode.
Serial Interface
ST7573 supports 3 kinds of serial interface and the type is selected by PS2~PS0 as shown below.
