Sanyo LC5738 Specifications

Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft’s
control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.

SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges,or other
parameters) listed in products specifications of any and all SANYO products described or contained

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)

LC5738

Notes for developing an LC5730 series microcontroller-used system.
The low current drain is a distinctive feature of the LC5730 series microcontroller.
However, it is not easy to determine the total current reguired for LC5730 series microcontroller-used system by
actual measurement when you develop a software, bacause much current flows in the peripherals of the evaluation
tools.
For a system which requires low current drain, check the current drain using an evaluation sample before mass­producting the system.

Specifications of any and all SANYO products described or contained herein stipulate the performance,
characteristics, and functions of the described products in the independent state, and are not guarantees
of the performance, characteristics, and functions of the described products as mounted in the customer's
products or equipment. To verify symptoms and states that cannot be evaluated in an independent device,
the customer should always evaluate and test devices mounted in the customer's products or equipment.

SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all
semiconductor products fail with some probability. It is possible that these probabilistic failures could
give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire,
or that could cause damage to other property. When designing equipment, adopt safety measures so
that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective
circuits and error prevention circuits for safe design, redundant design, and structural design.

In the event that any or all SANYO products(including technical data,services) described or
contained herein are controlled under any of applicable local export control laws and regulations,
such products must not be exported without obtaining the export license from the authorities
concerned in accordance with the above law.
