Frequently Asked Questions
Can PIC16F688 operate directly from a 3 V coin cell without a regulator?
Yes. The PIC16F688 operates from 2 V to 5.5 V, so a 3 V CR2032 coin cell can power the device directly. At 2 V the device runs up to 8 MHz using the internal oscillator, reducing external component count and board cost for battery-powered applications.
How many analog input channels are available on PIC16F688 for sensor measurement?
PIC16F688 includes an integrated 10-bit ADC with up to 8 analog input channels shared with the 12 I/O pins. This lets designers connect multiple resistive or voltage sensors simultaneously without adding an external ADC, making it useful for temperature, pressure, or light sensing applications.
What non-volatile storage does PIC16F688 provide for calibration data and configuration?
The PIC16F688 provides 256 bytes of data EEPROM in addition to 7 KB of program Flash. The EEPROM is byte-addressable and rated for 1 million erase/write cycles, making it ideal for storing calibration constants, device configuration, or runtime counters that must survive power cycling.
When would a designer choose PIC16F688 over a PIC12F675 for a compact 8-bit design?
PIC16F688 offers 7 KB Flash versus PIC12F675's 1.75 KB and provides 12 I/O pins versus 6 pins, along with USART serial communication. For designs needing a bootloader, UART debug port, or larger firmware image in a 14-pin through-hole package, PIC16F688 is the more capable choice.
