产品详细介绍
pic16f882/883/884/886/887
28/40/44-pin, enhanced flash-based 8-bit cmos microcontrollers with nanowatt technology
high-performance risc cpu:
• only 35 instructions to learn:
- all single-cycle instructions except branches
• operating speed:
- dc – 20 mhz oscillator/clock input
- dc – 200 ns instruction cycle
• interrupt capability
• 8-level deep hardware stack
• direct, indirect and relative addressing modes
special microcontroller features:
• precision internal oscillator:
- factory calibrated to ±1%
- software selectable frequency range of
8 mhz to 31 khz
- software tunable
- two-speed start-up mode
- crystal fail detect for critical applications
- clock mode switching during operation for
power savings
• power-saving sleep mode
• wide operating voltage range (2.0v-5.5v)
• industrial and extended temperature range
• power-on reset (por)
• power-up timer (pwrt) and oscillator start-up
timer (ost)

option
• enhanced low-current watchdog timer (wdt)
with on-chip oscillator (software selectable
nominal 268 seconds with full prescaler) with
software enable
• multiplexed master clear with pull-up/input pin
• programmable code protection
• high endurance flash/eeprom cell:

- auto-baud detect
- auto-wake-up on start bit
• in-circuit serial programmingtm (icsptm) via two
pins
• master synchronous serial port (mssp) module
supporting 3-wire spi (all 4 modes) and i2c™
master and slave modes with i2c address mask
