Overview
The LC866432A / 28A / 24A / 20A / 16A / 12A / 08A are 8-bit single chip microcontrollers with the following on-chip functional blocks:
• CPU : Operable at a minimum bus cycle time of 0.5µs (microsecond)
• On-chip ROM Maximum Capacity : 32K bytes
• On-chip RAM Capacity : 768 bytes (LC866432A / 28A / 24A) : 640 bytes (LC866420A / 16A) : 512 bytes (LC866412A / 08A)
• VFD automatic display controller / driver
• 16-bit timer / counter (or two 8-bit timers)
• 16-bit timer / PWM (or two 8-bit timers)
• 8 channel ✕ 8-bit AD converter
• Two 8-bit synchronous serial-interface circuits (1-channel ✕ 16-bit, 1-channel ✕ 8-bit)
• 14-source 10-vectored interrupt system All of the above functions are fabricated on a single chip.
