FEATURES
8K word on chip OTP-ROM and 56 bytes on chip special purpose registers and 384 bytes on chip general
purpose registers (SRAM).
8-level deep hardware stack.
7 real time down-count Timer/Counter with 3-bit programmable pre-scaler:
- TMR1: 10-bit (8+2), PWM1 & CPWM1 Period & Timer1.
- TMR2: 10-bit (8+2), PWM2 & CPWM1 Duty & Timer2.
- TMR3: 10-bit (8+2), PWM3 & CPWM2 Period & Timer3.
- TMR4: 10-bit (8+2), PWM4 & CPWM2 Duty & Timer4.
- TMR5: 10-bit (8+2), PWM5 & CPWM3 Period & Timer5.
- TMR6: 10-bit (8+2), PWM6 & CPWM3 Duty & Timer6.
- TMR7: 8-bit, Timer7.
Serial Peripheral Interface (SPI); Three-wire (or Two wire) synchronous communication.
Clock output: FOSC/2, /4, /8, /16, /32, /64 clock output, 3/4 duty clock output.
Built-in 5 levels Low Voltage Detector (LVDT) for Brown-out Reset (BOR).
Power-up Reset Timer (PWRT).
On chip Watchdog Timer (WDT) with internal oscillator for reliable operation.
Two I/O ports PORTA and PORTB with independent direction control:
- 15 Bi-direction I/O port (Programmable Pull-up enable in Input mode).
- One open-drain port (IOB3/RSTB).
Five kinds of interrupt source: 7 Timers/Counters, 6 external interrupt sources: IOA5~IOA7, IOB3~IOB5, SPI
interface, Internal watchdog timer (i_WDT) wakeup.
Wake-up from SLEEP:
- PORTA (IO5~IOA7) and PORTB (IOB3~IOB5) pin change wakeup.
- WDT overflow.
- i_WDT overflow.
HALT function reduce power consumption.
Power saving SLEEP mode.
Configurable CPU clock per instruction cycle: FOSC/4 and FOSC/2.
All instructions are single cycle except for program branches which are two-cycles.
Programmable Code Protection.
Six selectable oscillator options:
- ERC, XT, LF, 16MHZ/8MHZ HIRC, 500KHZ/250KHZ LIRC.
Wide-operating voltage range:
- OTP: 3.3V to 5.5V @ 8MIPS, 2.0V to 5.5V @ 4MIPS.
