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.

• Port
– Input port (S port, M port) : 2-port (8 pins) [Key scan input port]
– Input/Output port : 3-port (10 pins)

P0 port, P1 port 2-port (8 pins) [Key scan output port]
P2 port 1-port (2 pins) [Key scan expansion port]

[LED direct drivable port]

• Infrared remote control carrier generation circuit
– Software-controllable remote control carrier output ON/OFF.
– Software-controllable carrier frequency and duty ratio.

<38 kHz-1/3 duty, 38 kHz-1/2 duty, 57 kHz-1/2 duty>
(When fixed carrier signal is output, it is specified by mask option)

– 1 kHz to 200 kHz infrared remote control transmission carrier frequency.

(When carrier output is selected by timer at mask option, and when 455 kHz CR oscillator is used)

– Infrared carrier output-dedicated terminal built-in (CA terminal).
– 108 ms HALT-mode cancel signal output.

• Timer
– 16-bit software-controllable timer

Timer input clock : Ceramic (CR) oscillation frequency (455 kHz)

– 108 ms HALT release request signal generation timer (Free running timer)
– Watchdog timer (changed over between USED/UNUSED by mask option)

• Sub-routine stack level
– 2 levels

• Oscillation circuit
– Ceramic (CR) oscillation circuit : 455 kHz (for System clock generation), feedback resistor built-in.

• Standby function
– HALT mode

HALT mode used to reduce current drain.
HALT mode suspends program execution.

Following shows how to release the HALT mode.

(A) System reset
(B) HALT mode release request signal

– HOLD mode

HOLD mode stops ceramic resonator (CR). The HOLD mode can be released in two ways.
(A) System reset
(B) Apply H level input to S port pin or M port pin. (However, it is necessary to set S port or M port HOLD mode

release permission flag beforehand.)

• Form of shipment
– MFP-24S (1.0 mm pitch)

Note : When dipping in solder to mount the MFP package on board, contact SANYO for instructions.

Development Tools

• Tools for application development of the LC573100 Series
(1) Personal computer (MS-DOS based)
(2) Cross assembler (LC573100. EXE)
(3) Mask option generator (SU573100. EXE)

• Tools to evaluate application development of the LC573100 Series.
(1) EVA chip (LC5797)

Note : 1 As RAM capacity differs between EVA chip (LC5797) and the LC573100 Series, always check before

programming and debugging.
LC573010A/LC573015S : 64 × 4 bits
LC5797 : 256 × 4 bits

Note : 2 Always keep the DPH value in mind when programming. Only DPH ‘0’ to ‘3’ may be used as the RAM

address.
If DPH other than ‘0’ to ‘3’ is used as RAM address when programming, SANYO will not be liable for any
trouble caused.

(2) EVA chip board (TB5730)

Note : The application evaluation board is the evaluation board made by the user.

(3) Evaluation board [EVA420 (Monitor ROM : ER-573000)]
