Sanyo LC6514B 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
herein.

CMOS IC

Single-Chip 4-bit Microcontroller

(Low-Threshold Input, On-Chip FLT Driver)

Ordering number:ENN1802C

LC6514B

SANYO Electric Co.,Ltd. Semiconductor Company

TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN

Overview

The LC6514B is a microcontroller with FLT drivers. It is
identical with the LC6510C in the internal architecture and
instruction set. Since the normal/low-threshold lev el of in­put port A can be selected by option and the on-chip pull­down resistor can be bitwise connected to the FLT driver
by option, the number of external parts used in the user
equipment can be minimized, reducing the cost consider-

ably.

Features

• Low power dissipation.

• ROM capacity : 4096×8 bits.

• RAM capacity : 256×4 bits.

• Subroutine stack : 8 levels (common with interrupt).

• On-chip OSC circuit
CR OSC : 800kHz typ.
Ceramic OSC : 400kHz, 800kHz, 1000kHz
External iuput : 1290kHz max.

• Power-down by 2 standby modes
HAL T mode : Po wer dissipation sa ving by program stadby

during normal operation

HOLD mode : Power supply backup during power fail-

ure.

• Input/output ports
Input : 4 bits × 1 port

3 bits × 1 port
Input/output : 4 bits × 2 ports
Output : 4 bits × 4 ports

2 bits × 1 port

• Interrupt.
External interrupt : 1
Internal timer interrupt : 1

• On-chip 4-bit prescaler and 8-bit program timer.

• Instruction cycle time : 3.1µs (at 1290kHz)

• Supply voltage
Normal operation : 4.0 to 6.0 V
Memory hold : 1.8 to 6.0 V

• Instruction set common to the LC6502, LC6505 (BANK

instruction added)

Note
The LC6514B heretofore in use has been improved by changing the value of the pull-down resistor to be contained in
FLT drivers as shown below. When using the LC6514B, fully check that the new resistor value meets your application
specifications.
