Overview

The LC651154N/F/L and the LC651152N/F/L are the

small-scale control application versions of Sanyo’s

LC6500

series

of

4-bit

single-chip

CMOS

microcontrollers, and feature the same basic architecture

and instruction set. These microcontrollers include an 8-

input 8-bit A/D converter and are appropriate for use in a

wide range of applications, from applications with a small

number of circuits and controls that were previously

implemented in standard logic to applications with a larger

scale such as home appliances, automotive equipment,

communications equipment, office equipment, and audio

equipment such as decks and players. Also note that since

these ICs provide the same basic functions (certain

functions and specifications do differ) as, and are pin

compatible with the earlier LC651104N/F/L and

LC651102N/F/L, they can replace those ICs in most cases.

Features

• Fabricated in a CMOS process for low power (A

standby function that can be invoked under program

control is also provided.)

• ROM/RAM

LC651154N/F/L — ROM: 4K

× 8 bits,

RAM: 256

× 4 bits

LC651152N/F/L — ROM: 2K

× 8 bits,

RAM: 256

× 4 bits

• Instruction set: The 80-instruction set common to the

LC6500 family

• Wide operating supply voltage range: 2.2 to 6.0 V

(L versions)

• Instruction cycle time: 0.92 µs (F versions)

• On-chip serial I/O function

• Flexible I/O ports

— Number of ports: 6 ports with a total of 22 pins

— All ports:

· Are I/O ports

· I/O voltage handling capacity: 15 V (maximum)

(Open-drain specification C, D, E, and F ports

only)

· Output current: 20 mA (maximum) sink current

(Are capable of directly driving an LED.)

— Support options to match application system

specifications

A. Open-drain output, internal pull-up resistor

specification: All ports, in bit units

B. Output level at reset specification: Ports C and D

can be specified to go to the high or low level in

4-bit units.

• Interrupt function

— Timer interrupts through an interrupt vector (Can be

tested under program control)

— INT pin and serial I/O full/empty interrupts through

an interrupt vector (Can be tested under program

control)

• Stack levels: 8 (Shared with the interrupt system.)

• Timers: 4-bit variable prescaler and 8-bit programmable

timers

• Clock oscillator options that match a wide range of

system specifications

— Oscillator circuit options:

Two-pin RC oscillator (N and L versions)

Two-pin ceramic oscillator (N, F, and L versions)

— Clock divider circuit options:

No divider, built-in divide-by-3, built-in divide-by-4

(N and L versions)

• Continuous square wave output (with a period 64 times

the cycle time)

• A/D converter (successive approximation)

— 8-bit precision with 8 input channels

• Watchdog timer
