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.
Overview
The LC5822, LC5823, and LC5824 are CMOS
microcontrollers that feature the low-voltage operation
required for battery-power applications and that provide
4 KB, 6 KB, or 8 KB of ROM, 1 kilobit of RAM, and an
LCD driver.
These microcontrollers support an instruction set based on
that of the earlier LC5800, LC5812, and LC5814 for
excellent efficiency in software development.
Applications
LCD display in multi-function watches, timers, and
other products
Control and LCD display in timers
Control and LCD display in miniature test equipment,
health maintenance equipment, and other products
These microcontrollers are optimal for products that
include an LCD display, especially battery powered
products.
Wide Allowable Operating Ranges
Note
*
: When the backup flag is set, the BAK pin is connected to V
DD
.
Features
These microcontrollers are high-end versions of the
LC5800 and provide the following features.
Low Current Drain * In halt mode (typical)
Ceramic oscillator 400 kHz (3.0 V) 200 μA
Crystal oscillator 32 kHz (1.5 V, Ag specifications)
3.0 μA (LCD biases other than 1/3) 4.5 μA (LCD drive:
1/3 bias)
Crystal oscillator 32 kHz (3.0 V, Li specifications)
2.0 μA (LCD biases other than 1/3) 6.0 μA (LCD drive:
1/3 bias)
Timer and Counter Functions
One 8-bit programmable timer (May be used as an event
counter)
One 8-bit programmable reload timer
Time base timer (for clocks)
Watchdog timer
8-bit serial I/O (3-pin synchronous system)
Standby Functions
Clock standby function (halt mode)
Only the oscillator circuits, the divider circuit, and the
LCD driver operate. All other internal operations are
stopped. This provides a power-saving function in which
current drain is minimized, and allows a clock function
to be implemented easily with low power dissipation.
Furthermore, low-speed and high-speed modes can be
implemented by setting the operating modes of the two
oscillator circuits.
Full standby function (hold mode)
Halt mode can be cleared by any of two external and
two internal interrupts.
