ECHNOLOGY

OTP-Based 8-Bit Microcontroller

Devices Included in this Data Sheet:

 FM8PE531MA: 14-pin OTP device

 FM8PE531MB: 16-pin OTP device

GENERAL DESCRIPTION

The FM8PE531M is a low-cost, high speed, OTP-based 8-bit CMOS microcontrollers. It employs a RISC

architecture with only 37 instructions. All instructions are single cycle except for program branches which take two

cycles. The easy to use and easy to remember instruction set reduces development time significantly.

The FM8PE531M consists of Power-on Reset (POR), Brown-out Reset (BOR), Power-up Reset Timer (PWRT),

Watchdog Timer, OTP, SRAM, tristate I/O port, I/O pull-high control, Power saving SLEEP mode, real time

programmable clock/counter, Interrupt, PWM, Comparator (with CV_REF, Fixed Band Gap reference voltage), Wake-

up from SLEEP mode products.

FEATURES

 2K Word on chip OTP-ROM and 88 Bytes on chip general purpose registers (SRAM).

 6-level deep hardware stack.

 One analog comparator.

- Internal reference voltage: 16-step CV_REFmodule, 1.2V fixed voltage reference.

 One 16-bit real timer/Counter with 2-bit programmable pre-scaler.

 Two 8-bit fixed period-cycle PWM.

 Three channel 15-bit RFC.

 Six levels LVDT (Low Voltage Detect): 3.6V, 2.6V, 2.4V, 2.2V, 2.0V and 1.8V.

 Power-up Reset Timer (PWRT)

 On chip Watchdog Timer (WDT) with internal oscillator for reliable operation.

 Two I/O port, PORTA and PORTB with independent direction control:

- 13 Bi-direction I/O pin (Programmable Pull-up enable in Input mode).

- One Input /Open-drain pin (IOB3/RSTB).

 Two kinds of interrupt source:

- 4 internal interrupt sources: Timer1, RFC, Comparator and LVDT.

- 1 external interrupt sources: INT pin.

 Wake-up from SLEEP:

- ALL pin (IOA5~IOA0, IOB7~IOB0) input change wake-up.

- WDT overflow.

 Power saving SLEEP mode.

 Selectable oscillator options:

-HIRC: Internal Resistor/Capacitor 8M_HZOscillator.

-LIRC: Internal Resistor/Capacitor 55K_HZOscillator.

 Wide-operating voltage range: 2.0V to 5.5V.
