Frequently Asked Questions
At what minimum supply voltage can the PIC16F689-I/P operate, and what clock speed is supported at that voltage?
The PIC16F689-I/P operates at a minimum supply voltage of 2 V while supporting up to 8 MHz clock frequency at that voltage. This makes it suitable for single-cell lithium coin battery or dual-AA battery powered applications where supply voltage can drop below 3 V during discharge.
Which serial communication protocols does the PIC16F689-I/P support for connecting to external sensors?
The PIC16F689-I/P integrates EUSART for asynchronous UART and synchronous SPI communication, plus I2C master/slave support via the MSSP module. These 3 protocols allow direct interfacing with a wide range of sensors, memory chips, and displays using standard 2-wire or 4-wire connections without external bridge ICs.
How does the PIC16F689-I/P 10-bit ADC support multi-channel analog measurement in sensor applications?
The integrated 10-bit ADC provides 1024 discrete levels of resolution and supports multiple analog input channels, enabling measurement of sensor outputs such as thermistors, potentiometers, or light sensors. At 20 MHz, the ADC can complete conversion cycles in approximately 100 µs per channel, supporting multi-channel sequential scanning in embedded monitoring systems.
When would a designer choose the PIC16F689-I/P in PDIP-20 over an equivalent device in a smaller SMD package?
The PDIP-20 package with 2.54 mm pin pitch is chosen for designs using universal breadboards, socketed prototyping boards, or through-hole PCBs where SMT assembly equipment is unavailable. It offers 18 I/O pins in a familiar through-hole format, simplifying development of low-volume custom sensor interfaces and educational microcontroller projects without reflow soldering.
