Key Features

  • 8-bit PIC16 core running at up to 20 MHz with 7 KB flash for cost-effective embedded control
  • 256 bytes EEPROM for non-volatile parameter storage without external memory chips
  • Wide supply range from 2 V to 5.5 V enabling battery-powered and mixed-voltage system designs

Applications

The PIC16F689 is ideal for low-cost consumer appliances, battery-powered remote controls, and home-automation nodes that need non-volatile storage and an on-chip ADC in a tiny 20-pin QFN footprint. Its 2 V operating capability makes it suitable for two-cell battery applications requiring long standby times. Simple sensor-interface boards and motor-driver control cards also benefit from its rich peripheral set including comparators, USART, and SPI.

Frequently Asked Questions

How much on-chip memory does the PIC16F689 offer and how does that compare to the PIC16F688?

The PIC16F689 provides 7 KB of flash program memory, 256 bytes of EEPROM, and 256 bytes of RAM. The PIC16F688 offers the same 7 KB flash but lacks SPI/I2C hardware, making the PIC16F689 a better fit for sensor nodes that need a synchronous serial interface at up to 20 MHz.

At what supply voltage can the PIC16F689 operate, and what does that mean for battery-powered designs?

The PIC16F689 operates from 2 V to 5.5 V. At 2 V it still runs at up to 8 MHz, allowing direct operation from two AA cells without a boost converter, cutting system cost and quiescent current in portable devices that target 1 µA sleep modes.

Which analog peripherals are integrated in the PIC16F689 to reduce external component count?

The device integrates a 10-channel, 10-bit ADC, two comparators, an internal 4 MHz oscillator (±1% accuracy), and a programmable voltage reference, eliminating up to 4 discrete analog ICs on simple sensor-conditioning boards.

For a compact wearable sensor design, how much PCB area does the QFN-20 package require?

The QFN-20 package measures 4 mm × 4 mm with a 0.5 mm pitch, occupying only 16 mm² of board area — roughly half the footprint of a 20-pin SOIC package — making it well-suited for wearable and space-constrained IoT nodes.
