SED1230 Series

Dot Matrix LCD Controller Driver

SSC5000Series

■12 Character × 4 Line (5 × 7 dot)

■Built-in Character Generator ROM and RAM

■Built-in Power Supply Circuit for LCD

■ DESCRIPTION

The SED1230 Series is a dot matrix LCD controller driver for character display, and can display a maximum of 48

characters, 4 user-defined characters, and a maximum of 64 symbols by means of 4-bit, 8-bit or serial data sent

from a microcomputer.

A built-in character generator ROM is prepared for 256 character types, and each character font consists of 5 × 7

dots. A user-defined character RAM for four characters of 5 × 7 dots are incorporated, and a symbol register is also

incorporated. With these, it is possible to apply this Series to display with a high degree of freedom. This Series

can operate handy units with a minimum power consumption by means of its low power consumption and standby

mode.

The SED1230 Series are classified into SED1230, SED1231, SED1232, and SED1233 depending on the duty of

use and the number of display columns.

Notes: 1. All the voltage values are based on VDD = 0 V.

2. For voltages of V1, V2, V3 and V4, keep the condition of VDD ≥ V1 ≥ V2 ≥ V3 ≥ V4 ≥ V5 at all times.

3. If the LSI is used exceeding the absolute maximum ratings, it may lead to permanent destruction.

In ordinary operation, it is desirable to use the LSI in the condition of electrical characteristics. If the LSI

is used out of this condition, it may cause a malfunction of the LSI and have a bad effect on the reliability

of the LSI.

*1: A wide operating voltage range is guaranteed but an abrupt voltage variation in the access status of the MPU is not

guaranteed.

*2: The operating voltage range is applicable to the case where an external power supply is used.

*3: D0 - D5, D6 (SCL), D7 (SI), A0, RES, CS WR (E), P/S, IF

*4: This is a resistance value when a voltage of 0.1 V is applied between output pin SEGn, SEGSn, COMn or COMSn, and each

power pin (V1, V2, V3 or V4). It is specified in the range of operating voltage (2).

RON = 0.1 V / ∆I

(∆I: Current flowing when 0.1 V is applied between the power and output)

*5: Character “

” display. This is applicable to the case where no access is made from the MPU and the built-in power circuit

and oscillating circuit are in operation.

*6: This is applicable to the case where the built-in power circuit is OFF and the oscillating circuit is in operation in the standby

mode.

*7: Current consumption when data is always written by fcyc.

The current consumption in the access state is almost proportional to the access frequency (fcyc).

When no access is made, only IDD (I) occurs.

*8: tR (reset time) indicates the internal circuit reset completion time from the edge of the RES signal. Accordingly, the SED123

usually enters the operating state after tR.

*9: The minimum pulse width of the RES signal is specified.

To cause a reset operation, it is necessary to input a pulse width exceeding tRW.

*10: When operating the boosting circuit, the power supply VSS must be used within the input voltage range.
