Low Pincount PIC Micros

The PIC12F683, PIC16F684 and PIC16F688 microcontrollers offer up to 7,168 bytes 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 8 channels of 10-bit A/D. In addition, they support a wide operating voltage of 2.0 - 5.5 volts.

The PIC12F683 features a stan­dard Copture/Compare/PWM module, while the PIC16F684 features an Enhanced Capture/Compare/PWM mod­ule with deadband control, up to 4 outputs ond emergency shut­down. The PIC16F688 features an EUSART peripheral to support RS232/485-type communica­tions and the UN protocol.

Microchip’s existing 8- and 14-pin Flash devices already offer nanoWatt technology features such as nanoAmp standby cur­rent, fast-startup internal oscilla­tor, and Brown-out detection for reliable operation. These new devices offer additional power-management features such as software-selectable clock speed, software-controlled Brown-out 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).
