CMOS IC
LC5824, LC5823, LC5822
4-Bit Single-Chip Microcontrollers Featuring 4 KB to 8 KB of ROM, 1 Kbit of RAM, and an LCD Driver for Medium Speed Small-Scale Control Applications
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.
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 A * Crystal oscillator 32 kHz (1.5 V, Ag specifications) 3.0 A (LCD biases other than 1/3) 4.5 A (LCD drive: 1/3 bias) * Crystal oscillator 32 kHz (3.0 V, Li specifications) 2.0 A (LCD biases other than 1/3) 6.0 A (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.
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.

Specifications of any and all SANYO products described or contained herein stipulate the performance, characteristics, and functions of the described products in the independent state, and are not guarantees of the performance, characteristics, and functions of the described products as mounted in the customer's products or equipment. To verify symptoms and states that cannot be evaluated in an independent device, the customer should always evaluate and test devices mounted in the customer's products or equipment. SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all semiconductor products fail with some probability. It is possible that these probabilistic failures could give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire, or that could cause damage to other property. When designing equipment, adopt safety measures so that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective circuits and error prevention circuits for safe design, redundant design, and structural design. In the event that any and all SANYO products described or contained herein fall under strategic products (including services) controlled under the Foreign Exchange and Foreign Trade Control Law of Japan, such products must not be exported without obtaining export license from the Ministry of International Trade and Industry in accordance with the above law.
