TECHNOLOGY
FM8PE68B
OTP-Based 8-Bit Microcontroller with LCD Driver
Devices Included in this Data Sheet:
FM8PE68BA/BB: 64-pin OTP device
FM8PE68BC: 44-pin OTP device
FEATURES
Only 49 single word instructions.
4K Word on chip OTP.
All OTP area GOTO/FGOTO instruction.
All OTP area subroutine CALL/FCALL instruction.
Totally 272 x 8 bits on chip general purpose registers (SRAM):
- 144 bytes general purpose register.
- 128 bytes on-chip data RAM.
8-level deep hardware stack.
Direct, indirect addressing modes for data accessing.
One 8-bit real time clock/counter (Timer0) with 8-bit programmable pre-scaler.
Four sets of 8-bit auto reload counter/timer can be used as IROUT/PWM generator or interrupt sources:
- Counter 1: independent counter.
- Counter 2: High Pulse Width Timer, and Low Pulse Width Timer shared with IR function.
One IROUT/PWM generator.
LCD driver with 4(common) x 32(segment) pixels; 1/3, 1/2 bias and 1/4, 1/3, 1/2 duty selection.
3 channels of 15-bit resolution Resistor to Frequency Converter (RFC) output.
Internal Power-on Reset (POR).
Built-in Low Voltage Detector (LVD) for Brown-out Reset (BOR).
Power-up Reset Timer (PWRT) and Oscillator Start-up Timer(OST).
On chip Watchdog Timer (WDT) with internal oscillator and soft-ware watch-dog enable/disable control.
Four I/O ports PORTA, PORTB, PORTC and PORTD with independent direction control.
Two output only ports PORTE and PORTF.
Soft-ware I/O pull-high/pull-down or open-drain control.
Seven internal interrupt source: Timer0, Counter1, Counter2, High-pulse width timer, Low-pulse width timer, RFC
and Fs divider; Three external interrupt source: INT0 pin, INT1 pin and Port B / Port D input status change.
Wake-up from SLEEP/IDLE by Port B/Port D input change.
Operation modes:
- Normal mode: CPU operate on high frequency main-oscillator.
- Green mode: CPU operate on low frequency sub-oscillator.
- Idle mode: CPU idle, LCD display remains working.
- Sleep mode: whole chip stop working.
Dual clock Operation: main-oscillator and sub-oscillator.
Selectable main-oscillator options:
- ERIC: External Resistor/Internal Capacitor Oscillator.
- XT: Crystal/Resonator Oscillator.
- LF: Low Frequency Crystal/Resonator Oscillator.
- PLL: Phase lock loop.
Selectable sub-oscillator options:
- ERIC: External Resistor/Internal Capacitor Oscillator.
- LF: Low Frequency Crystal Oscillator.
Wide-operating voltage range:
- OTP: 2.3V to 5.5V.
