The LC866448B/44B/40B/36B/32B/28B/24B/20B/16B/12B/08B 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 (microsecond)
The LC866448B/44B/40B/36B/32B/28B/24B/20B/16B/12B/08B are constructed to read ROM twice within one
instruction cycle. It has 1.7 times more performance capability within the same instruction cycle compared to our 4-bit
microcomputers (LC66000 series).
Bus cycle time indicates the speed to read ROM.

(13) Real-time service operation
The Real-Time Service (RTS) functions the 4-byte data-transfer between the Special Function Registers at
acknowledging the interrupt request.
The RTS starts within 1 instruction cycle-time and completes within 5 instructions cycle-time after occurring the
interrupt request.
(14) Subroutine stack levels
- 128 levels (Max.): Stack area included in RAM area
- On-chip RC oscillation circuit using for the system clock.
- On-chip CF oscillation circuit using for the system clock.
- On-chip crystal oscillation circuit using for the system clock and for time-base clock.
(17) Standby function
- HALT mode function
The HALT mode is used to reduce power dissipation. In this operation mode, program execution is stopped. This
operation mode can be released by interrupt request signals or the initial system reset request signal.
- HOLD mode function
The HOLD mode is used to freeze all the oscillations;
RC (internal), CF and Crystal oscillations. This mode can be released by the following operations.
• Reset terminal (
• P70/INT0/T0IN, P71/INT1/T0IN terminals set to assigned level (programmable)
• Input a Port 0 interrupt condition

(Note 4) The currents of the output transistors and the pull-up MOS transistors are ignored.
* Both C3 and C4 must be use J rank (±5%) and CH characteristics.
(Not in need of high precision, use K rank (±10%) and SL characteristics.)
(Notes) • Please place the oscillation-related parts as close to the oscillation pins as possible with the shortest
possible pattern length since the circuit pattern affects the oscillation frequency.
• If you use other oscillators herein, we provide no guarantee for the characteristics.
