8-Bit CMOS Microcontrollers with USB

• PIC16C745 • PIC16C765

Microcontroller Core Features:

• High-performance RISC CPU
• Only 35 single word instructions
• All single cycle instructions except for program
  branches which are two cycle
• Interrupt capability (up to 12 internal/external
  interrupt sources)
• Eight level deep hardware stack
• Direct, indirect and relative addressing modes
• 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
• Brown-out detection circuitry for
  Brown-out Reset (BOR)
• Programmable code-protection
• Power saving SLEEP mode
• Selectable oscillator options
  - EC - External clock (24 MHz)
  - E4 - External clock with PLL (6 MHz)
  - HS - Crystal/Resonator (24 MHz)
  - H4 - Crystal/Resonator with PLL (6 MHz)
• Processor clock of 24 MHz derived from 6 MHz
  crystal or resonator
• Fully static low-power, high-speed CMOS
• In-Circuit Serial Programming? (ICSP)
• Operating voltage range
  - 4.35 to 5.25V
• High Sink/Source Current 25/25 mA
• Wide temperature range
  - Industrial (-40°C - 85°C)

  - ~ 16 mA @ 5V, 24 MHz
  - 100 µA typical standby current

Peripheral Features:

• Universal Serial Bus (USB 1.1)
  - Soft attach/detach
• 64 bytes of USB dual port RAM
• 22 (PIC16C745) or 33 (PIC16C765) I/O pins
  - Individual direction control
  - 1 high voltage open drain (RA4)
  - 8 PORTB pins with:
  - Interrupt-on-change control (RB<7:4> only)
  - Weak pull-up control
  - 3 pins dedicated to USB
• Timer0: 8-bit timer/counter with 8-bit prescaler
• Timer1: 16-bit timer/counter with prescaler
  can be incremented during SLEEP via external
  crystal/clock
• Timer2: 8-bit timer/counter with 8-bit period
  register, prescaler and postscaler
• 2 Capture, Compare and PWM modules
  - Capture is 16-bit, max. resolution is 10.4 ns
  - Compare is 16-bit, max. resolution is 167 ns
  - PWM maximum resolution is 10-bit
• 8-bit multi-channel Analog-to-Digital converter
• Universal Synchronous Asynchronous Receiver
  Transmitter (USART/SCI)
