The PIC12F683, PIC16F684 and PIC16F688 microcontrollers offer up to 7Kbyte of Flash program memory, making use of Microchip's PEEC Flash technology offering one million erase/write cycles.

The PIC12F683, PIC16F684 and PIC16F688 microcontrollers offer up to 7Kbyte of Flash program memory, making use of Microchip's PMOS electrically erasable cell (PEEC) Flash technology offering one million erase/write cycle endurance.

The devices also include onboard EEPROM data memory, and offer several peripheral options with integrated nanowatt technology.

Standard analogue peripherals include single or dual comparators, and up to eight channels of 10bit ADC.

In addition, they support a wide operating voltage of 2.0-5.5V.

The PIC12F683 features a standard capture/compare/PWM module, whereas the PIC16F684 features an enhanced capture/compare/PWM module with deadband control, up to four outputs and emergency shutdown.

The PIC16F688 features an EUSART peripheral to support RS232/485-type communications and the LIN protocol.

Microchip's existing 8- and 14-pin Flash devices already offer nanowatt technology features such as nanoampere standby current, fast-startup internal oscillator, and brownout detection for reliable operation.

These new devices offer additional power-management features such as software-selectable clock speed, software-controlled brownout detection, ultra-low-power wakeup on change, a lower-power real time clock timer and an extended watchdog timer.

These provide maximum flexibility in managing power consumption, without sacrificing system reliability.

The three new PIC microcontrollers come in small-footprint 8-pin SOIC and 14-pin TSSOP packages.

The devices are supported by Microchip's development tools, including the PICkit 1 Flash starter kit, MPLAB IDE (integrated development environment), and the MPLAB ICD 2 (in-circuit debugger).
