ETR Controllers
Overview
The LC723661, 723662 and 723663 are ETR controllers that can support up to 64KB of ROM and up to 4KB of RAM.
These are an 80-pin version of the 100-pin LC723780 series.
They have a built-in serial I/O port and 6-input 8-bit A/D converter to enhance communication with the internal and
external devices.
Functions
• ROM
• RAM
• Stack
• Serial I/O
• External interrupts
• Internal interrupts
: Up to 32K steps (32767×16-bits)
The subroutine area holds 4K steps (4,096×16-bits)
: Up to 8K×4-bits (In banks 00 through 7F)
LC723661-ROM 32KB, RAM 2KB
LC723662-ROM 48KB, RAM 2KB
LC723663-ROM 64KB, RAM 4KB
: 32 levels
: Two channels. These circuits can support both 2-wire and 3-wire 8-bit communication
techniques, and can be switched between MSB first and LSB first operation.
One of six internally generated serial transfer clock rates can be selected: 12.5kHz,
37.5kHz, 187.5kHz, 281.25kHz, 375kHz, and 450kHz
: Five interrupt inputs (pins INT0, 1, 4, and 5, and the HOLD pin)
These interrupts can be set to switch between rising and falling edges, although the HOLD
pin only supports falling edge detection.
: Six interrupts ; four internal timer interrupts, and two serial I/O interrupts.

These pins output a high level when the frequency of the local
oscillator divided by n is higher than that of the reference frequency,
and they output a low level when that frequency is lower.
They go to the high-impedance state when the frequencies match.
These pins go to the high-impedance state in Backup mode, after a

Universal counter and general-purpose input shared function input port.
The IOS1 instruction is used for switching between the universal

counter and general-purpose input functions.
• When used for frequency measurement :
The universal counter function is set up with the IOS1 instruction.
The counter is controlled using UCS and UCC instructions.
Since this pin functions as an AC amplifier in this mode, the input
signal must be input with capacitor coupling.
• When used as a general-purpose input pin :
The general-purpose input function is set up with the IOS1
instruction.
Data is read from the port using the INR (b0) instruction.
Input is disabled in Backup mode. (The input pin will be pulled down.)
The universal counter function is selected after a power on reset.

Pin explanation
Equivalent circuit
Universal counter (frequency or period measurement) and generalpurpose input shared function input port.
The IOS1 instruction is used for switching between the universal
counter and general-purpose input functions.
• When used for frequency measurement :
The universal counter function is set up with the IOS1 instruction.
Set up LCTR frequency measurement mode with the UCS
instruction, and control operation with the UCC instruction.
Since this pin functions as an AC amplifier in this mode, the input
signal must be input with capacitor coupling.
• When used for period measurement :
The universal counter function is set up with the IOS1 instruction.
PLL Stop instruction
Set up LCTR frequency measurement mode with the UCS
instruction, and control operation with the UCC instruction.
ILC05536
Since the bias feedback resistor is disconnected in this mode, the
input signal must be input with DC coupling.
• When used as a general-purpose input pin :
The general-purpose input port function is set up with the IOS1
instruction.
Data is read from the port using the INR (b1) instruction.
Input is disabled in Backup mode. (The input pin will be pulled down.)
The universal counter function (HCTR frequency measurement mode)
is selected after a power on reset.
SNS
70
I
Voltage sense and general-purpose input shared function port.
This input circuit is designed with a low input threshold voltage.
• When used as a voltage sense input :
The pin is used to test for power failures on the return from Backup
mode.
Application can test this condition using the internal SNS flip-flop.
The SNS flip-flop can be tested with the TST instruction.
(This usage requires external components, capacitors and resistors.
For the sample application circuit, see the user’s manual.)
ILC05539
• When used as a general-purpose input port :
When used as a general-purpose input port the pin state can be
tested with the TST instruction.
Unlike the other input ports, input to this pin is not disabled in Backup
mode and after a power on reset. As a result, through currents must
be taken into account when designing applications that use this pin as
a general-purpose input.
HOLD
69
I
Power supply monitor (with interrupt function)
This is designed with a high input threshold voltage.
This pin is normally connected to the ACC line and used for power off
detection.
When a power off state is detected, the HOLDON flag and the hold
interrupt request flag will be set.
ILC05539
To enter Backup mode, execute a CKSTP instruction when the HOLD
pin is low. Set this pin high to clear Backup mode.
RESET
68
I
System reset pin.
When the CPU is operating or in Halt mode, the system is reset when
this pin is held low for at least one machine cycle. Execution starts
with the PC pointing to location 0. At this time the SNS flip-flop is set.
A low level must be applied for at least 50ms when power is first
ILC05540
applied.

ILC05542
General-purpose I/O and external interrupt shared function ports.
The input formats are Schmitt inputs.
The external interrupt function is enabled when the external interrupt
enable flag is set.
• When used as general-purpose I/O ports :
The mode (input or output) is set in 1-bit units using the IOS1
BACK UP
instruction.
• When used as external interrupt pins :
The external interrupt functions are enabled by setting the
corresponding external interrupt enable flag (INT0EN through
ILC05543
INT3EN). Here, the pins must be set to input mode in advance.
Input is disabled and the pins go to the high-impedance state in
Backup mode.

When this pin is used as the beep tone output pin, executing an
output instruction for this pin only sets the internal latch and has no
influence on the output.

Backup mode.
