1 / 24 page 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 VDD. 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.
