OVERVIEW This data sheet covers the PIC17C4X group of the PIC17CXX family of microcontrollers. The following devices are discussed in this data sheet: • PIC17C42 • PIC17CR42 • PIC17C42A • PIC17C43 • PIC17CR43 • PIC17C44 The PIC17CR42, PIC17C42A, PIC17C43, PIC17CR43, and PIC17C44 devices include architectural enhancements over the PIC17C42. These enhancements will be discussed throughout this data sheet. Microcontroller Core Features: • Only 58 single word instructions to learn • All single cycle instructions (121 ns) except for program branches and table reads/writes which are two-cycle • Operating speed: - DC - 33 MHz clock input - DC - 121 ns instruction cycle • Hardware Multiplier (Not available on the PIC17C42) • Interrupt capability • 16 levels deep hardware stack • Direct, indirect and relative addressing modes • Internal/External program memory execution • 64K x 16 addressable program memory space Peripheral Features: • 33 I/O pins with individual direction control • High current sink/source for direct LED drive - RA2 and RA3 are open drain, high voltage (12V), high current (60 mA), I/O • Two capture inputs and two PWM outputs - Captures are 16-bit, max resolution 160 ns - PWM resolution is 1- to 10-bit • TMR0: 16-bit timer/counter with 8-bit programmable prescaler • TMR1: 8-bit timer/counter • TMR2: 8-bit timer/counter • TMR3: 16-bit timer/counter • Universal Synchronous Asynchronous Receiver Transmitter (USART/SCI) 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 • Code-protection • Power saving SLEEP mode • Selectable oscillator options CMOS Technology: • Low-power, high-speed CMOS EPROM/ROM technology • Fully static design • Wide operating voltage range (2.5V to 6.0V) • Commercial and Industrial Temperature Range • Low-power consumption - < 5 mA @ 5V, 4 MHz - 100 µA typical @ 4.5V, 32 kHz - < 1 µA typical standby current @ 5V
