Flexible Clock Management System for PIC Microcontrollers

Tap into the power of versatility in your next embedded system design with Microchip Technology’s Low Pin-CountPIC® Flash microcontrollers. These 8- and 14-pin devices provide a unique combination of robust program memoryand popular peripheral options along with industry leading power management choices. These microcontrollers are well suited for a wide range of applications including home appliances, battery-operated or handheld products, sensors, automotive and general-purpose control functions.

Based on the PIC x14 architecture, these microcontrollers provide leading edge performance via design features such as a modified Harvard 14-bit instruction set, single cycle and single word instructions, sophisticated hardware peripherals and advanced on-chip analog peripherals. Key standard features include a wide operating voltage of 2.0-5.5 volts, on-board EEPROM data memory and precision internal oscillator along with analog peripherals such as up to 8 channels of 10-bit ADC and an analog comparator module with programmable on-chip voltage reference. Additional on-chip peripherals include a Capture/Compare/PWM (CCP) or Enhanced Capture/Compare/PWM (ECCP). The ECCP peripheral provides up to four outputs with programmable dead band delay and auto-shutdown and restart options. Serial communication is offered with the Enhanced USART (EUSART) peripheral that supports communications protocols such as RS232/485 as well as the LIN protocol.

These new PIC devices also provide designers with the most advanced and reliable Flash memory technology available—Microchip’s PMOS Electrically Erasable Cell (PEEC) Flash technology. PEEC Flash increases reliability through in-field reprogrammability that can withstand one million erase/write cycles on each memory location at a wide range of operating temperatures.

Versatile Low Pin-Count PIC® Flash Microcontrollers

For more details on the PIC12F and PIC16F microcontroller families, visit www.microchip.com.

Featuring the proprietary nanoWatt Technology, these Low Pin-Count PIC Flash microcontrollers give you the versatility to reduce system power consumption, increase reliability and performance, and minimize cost by eliminating external components. nanoWatt Technology provides the system designer greater control of on-board peripherals, including an 8 MHz internal oscillator with several software selectable speed options down to 32 kHz. Extremely low sleep current consumption combined with a fast startup internal oscillator enables low power consumption system design. Periodic wake-up mechanisms include low power real time clock (Timer1) operation, ultra low power wake-up feature and an extended low power Watchdog Timer (WDT). Even at very low power, the devices offer reliable operation with a software selectable Brownout Reset (BOR) circuit.
