Overview
The LC587408A/06A/04A microcontrollers have a CPU (enables functions with the low-voltage) as a core and
is the CMOS 4-bit microcontrollers with 8K/6K/4K x 16-bit ROM, 512 x 4-bit RAM, stack-only RAM(8
levels), 8-bit AD x 4 ch, 8-bit timer x 2 channels (one used as an event counter), 8-bit synchronous serial
interface,the alarm signal generation circuit, remote control carrier generation circuit, LCD controller and
driver, and powerful stand-by function (power-saving function) all mounted as one chip.
Usage
• Functions for handy materials with LCD function (suitable for applications of low-power battery
comsumption)
• Portable CD, timer, health control and management machine control and LCD display
• Remote controllers for the CD, VTR, tuners.
