LC865504A
Overview
The LC865520A/16A/12A/08A/04A microcontrollers are 8-bit single chip microcontrollers with the following one-chip functional blocks:
- CPU : Operable at a minimum bus cycle time of 0.5µs (microsecond)
- On-chip ROM Maximum Capacity : 20K bytes ..
- On-chip RAM Capacity : 512 bytes (LC865520A/16A/12A/08A/04A)
- 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
- 13-source 10-vectored interrupt system80
All of the above functions are fabricated on a single chip.
