  PIC14000 Datasheet (4/1/2003)


High-Performance RISC CPU:

• Only 35 single word instructions to learn
• All single cycle instructions except for program
branches which are two cycle
• Operating speed: DC - 20 MHz clock input
• 4096 x 14 on-chip EPROM program memory
• 192 x 8 general purpose registers (SRAM)
• 6 internal and 5 external interrupt sources
• 38 special function hardware registers
• Eight-level hardware stack

Analog Peripherals Features:

• Slope Analog-to-Digital (A/D) converter
- Eight external input channels including two
channels with selectable level shift inputs
- Six internal input channels
- 16-bit programmable timer with capture
register
- 16 ms maximum conversion time at maxi-
mum (16-bit) resolution and 4 MHz clock
- 4-bit programmable current source
• Internal bandgap voltage reference
• Factory calibrated with calibration constants
stored in EPROM
• On-chip temperature sensor
• Voltage regulator control output
• Two comparators with programmable references
• On-chip low voltage detector

Special Microcontroller Features:

• Power-on Reset (POR), Power-up Timer (PWRT)
and Oscillator Start-up Timer (OST)
• Watchdog Timer (WDT) with its own on-chip RC
oscillator for reliable operation
• Multi-segment programmable code-protection
• Selectable oscillator options
-  Internal 4 MHz oscillator
-  External crystal oscillator
•  Serial in-system programming (via two pins)
Digital Peripherals Features:

• 22 I/O pins with individual direction control
• High current sink/source for direct LED drive
• TMR0: 8-bit timer/counter with 8-bit
programmable prescaler
• 16-bit A/D timer: can be used as a general
purpose timer
•I2C serial port compatible with System
Management Bus

CMOS Technology:

• Low-power, high-speed CMOS EPROM technology
• Fully static design
• Wide-operating voltage range (2.7V to 6.0V)
• Commercial and Industrial Temperature Range
• Low power dissipation (typical)
- < 3 mA @5V, 4 MHz operating mode
- < 300 µA @3V (Sleep mode: clocks stopped
with analog circuits active)
- < 5 µA @3V (Hibernate mode: clocks
stopped, analog inactive, and WDT disabled)

Applications:

• Battery Chargers
• Battery Capacity Monitoring
• Uninterruptable Power Supply Controllers
• Power Management Controllers
• HVAC Controllers
• Sensing and Data Acquisition
