What are the key features of PIC16F688-I/SL?
- 8-channel 10-bit ADC enabling precise multi-sensor acquisition from a 2 V minimum supply rail for battery-powered sensing nodes
- Integrated USART and SPI/I2C-compatible MSSP port supporting up to 5 Mbps data rates for serial communication without external bridge ICs
- 7 KB self-programmable Flash with 100,000 erase/write endurance cycles and in-circuit serial programming (ICSP) for field firmware updates
What is PIC16F688-I/SL used for?
The PIC16F688 is a strong fit for low-power consumer and industrial sensing applications such as temperature loggers, proximity detectors, and soil-moisture monitors that run from a single AAA cell at 2 V. Its 12 I/O lines and integrated USART make it ideal for HVAC damper controls and small appliance interfaces where a compact SOIC-14 footprint and 20 MHz throughput satisfy tight board-space and cost constraints. Remote sensor nodes and battery-operated alarm panels benefit from its deep sleep currents and wide operating voltage down to 2 V.

Frequently Asked Questions
What ADC resolution and channel count does the PIC16F688 offer for multi-sensor data acquisition designs?
The PIC16F688 provides an 8-channel, 10-bit successive-approximation ADC with a conversion time as fast as 1.6 µs at 20 MHz, enabling sequential sampling of up to 8 analog inputs such as NTC thermistors, light sensors, and 0–5 V pressure transducers within a single 3.3 V or 5 V supply system.
How does the PIC16F688 perform in battery-powered applications requiring a 2 V minimum supply?
The PIC16F688 operates fully from 2.0 V to 5.5 V and achieves active current below 1.5 mA at 8 MHz, 2 V, while deep sleep (Power-Down) mode draws under 100 nA, making it suitable for coin-cell or AAA-battery designs with multi-year field life in wireless sensor nodes and remote controls.
Which serial interfaces are built into the PIC16F688, and what baud rates do they support for host MCU communication?
The PIC16F688 integrates an Enhanced USART capable of up to 1.25 Mbps asynchronous baud rates and a Master Synchronous Serial Port (MSSP) supporting SPI mode at up to 5 Mbps and I2C at 400 kHz Fast mode, removing the need for external UART or SPI bridge ICs in 20 MHz clocked designs.
For a compact sensor board, how much PCB space does the SOIC-14 package of the PIC16F688-I/SL require?
The SOIC-14 package measures 8.65 mm x 3.9 mm with a 1.27 mm pin pitch, consuming under 34 mm² of PCB area, allowing integration alongside decoupling capacitors and a crystal in a 20 mm x 15 mm sensor board section typical of wearable fitness or environmental monitoring modules.
When does a designer choose PIC16F688 over PIC16F676 for an 8-bit control project?
When the design needs 7 KB versus 1 KB of Flash for more complex firmware, or requires USART for RS-232 or MODBUS at 9600 bps to 1.25 Mbps, the PIC16F688 is preferred because the PIC16F676 lacks a hardware USART, forcing a software-bit-bang UART that consumes up to 40% CPU overhead at 20 MHz clock.
