CMOS IC
LC86F1216A
8-Bit Single Chip Microcontroller with
16K-Byte ROM and 1220-Byte RAM On Chip
Preliminary
Overview
The LC86F1216A is an 8-bit single chip microcontroller with the following on-chip functional blocks:
- CPU: Operable at a minimum bus cycle time of 0.5µs
- On-chip Flash EEPROM capacity: 144 Kbytes
- On-chip RAM capacity: 1222 bytes
- Dot matrix liquid crystal display controller / driver
- 16-bit timer/counter (or two channels × 8-bit timer)
- 16-bit timer/PWM (or two channels × 8-bit timer)
- Serial interface circuit
All of the above functions are fabricated on a single chip.

Note
The microcontroller will malfunction if the power supply voltage is less than the specified operable supply voltage. To
prevent a malfunction, the low voltage detect circuit should be connected externally, and the voltage should always be set
to the proper level. If the power supply voltage becomes lower than the voltage which is detected by the low voltage detect
reset IC, then the microcontroller should be reset to restore stable operation. Use the low voltage detect reset IC which
detects the lowest specification voltage of the power supply.
We cannot ensure the integrity of the block data, if the microcontroller is reset while writing to the flash memory.
Therefore, in such a case, we recommend disabling any flash writing operation by user's program when the voltage
decreases to a level just above the voltage which is detected by the low voltage detect reset IC.

•
For further assistance, please contact with the oscillator
Since the oscillation frequency precision is affected by wiring capacity of the application board, etc., adjust the oscillation
frequency on the production board.
Since the oscillation circuit characteristics are affected by the noise, wiring capacity, etc., refer to the following notices.
• The distance between the clock I/O terminal and external parts should be as short as possible.
• The capacitors’ VSS should be allocated close to the microcontroller’s GND terminal and be away from other GND.
• The signal lines with rapid state changes or the signal line with large amplitude such as middle withstand voltage port or LCD
driver output should be allocated away from the clock oscillation circuit.
• The signal lines with large current should be allocated away from the oscillation circuit.
