Description
Ordering number : ENN*6724
CMOS IC
LC868116/12/08A
8-Bit Single Chip Microcontroller with 16/12/08K-Byte ROM and 640-Byte RAM On Chip
Preliminary Overview
The LC868116A/12A/08A microcontrollers are 8-bit single chip microcontrollers with the following on-chip functional blocks : - CPU : Operable at a minimum bus cycle time of 0.5µs (microseconds) - On-chip ROM maximum capacity : 16K bytes - On-chip RAM capacity : 640 bytes - Dot-matrix liquid crystal display (LCD) automatic display controller / driver - External memory - 16-bit timer / counter (or two 8-bit timers) - 16-bit timer / PWM (or two 8-bit timers) - Two 8-bit synchronous serial-interface circuits - 13-source 9-level vectored interrupt system All of the above functions are fabricated on a single chip
