CMOS IC
4-Bit Single Chip Microcontroller
with LCD Drivers
for Low-Voltage, Low Power Use
Ordering number:ENN3540
LC5738
SANYO Electric Co.,Ltd. Semiconductor Company
TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN
Overview
The LC5738 is a single-chip 4-bit microcontroller with LCD
drivers. The features of the LC5738 include low voltage
operation, low power dissipation, etc. The HALT function,
which can be used to stop/start the CPU operations, facilitates the low power dissipation of the system. The LC5738
is ideally suited for use in melody function-provided timepiece/timer, game, functional watch and calculator application.

Development Support System
The development support system for the LC5738 applications consists of the following support tools :
(1) Manual
(a) User’s Manual : LC5738 user’s manual
(b) Tool Manual : LC5738 tool manual
(2) Development support tools
(a) Tools for developing the LC5738 application programs.
- MS-DOS machine
- Assembler (LC5738. EXE)
- Mask option selections program (SU5738. EXE)
(b) Tools for evaluating the LC5738 application systems.
- Evaluation chip : LC5797
Note 1) Since the evaluation chip LC5797 differs LC5738 with RAM capacity, be sure to check the RAM capacity
when preparing or debugging programs.
LC5738 : 48×4 bits, LC5797 : 256×4 bits
Note 2) When dev eloping pro grams, tak e care of the DPH value. The usable DPH v alues are 0 to 2 ex cept ROM bank
selection.
We will be free from any blame even if you use DPH=3 to FH for RAM addressing.
- Evaluation chip board : TB5738
Note) The application evaluation board is constructed by the user.
LCD or LEDs may be used for display.
- Evaluation board : EVA520 (monitor ROM : SCR5738)
Note) The EVA-520 is a modified version of the EVA-420 whose monitor ROM is replaced by the SCR-5738.
- Display and mask-option data control board : DCB-1 (Rev.3.3)

• The pad coordinates are such that the chip enter is taken as the origin and the values for (X, Y) represent the coordinates
of the center point of each pad.
• Pin 16, 17 are NC pins.
• The NC pins must not be connected externally.
