What are the key features of PIC16F1705-I/ST?
- 8192-word Flash and 1024-byte RAM in an 8-bit PIC16 core at up to 32 MHz support complex control algorithms with generous code storage in a 14-pin TSSOP
- Integrated LIN and I2C interfaces enable direct connection to automotive sensor networks and I2C peripheral buses without external transceivers or bridge ICs
- Operates from 2.3 V minimum at 16 MHz, enabling battery-powered or low-voltage rail designs that tolerate wide supply variation without voltage regulation
What is PIC16F1705-I/ST used for?
PIC16F1705-I/ST is designed for automotive body control modules, LIN-connected sensor nodes, and small home appliance motor controllers where an 8-bit core running at up to 32 MHz is sufficient. Its integrated LIN interface allows it to act as a LIN slave node for functions such as window lift, seat adjustment, or climate control actuators without a separate LIN transceiver IC. The compact 14-pin TSSOP footprint and low 2.3 V minimum supply also make it attractive for battery-powered industrial sensors and smart lighting controls that require both analog sensing and digital communication.

Frequently Asked Questions
What communication interfaces are built into PIC16F1705-I/ST and which automotive bus does it natively support?
PIC16F1705-I/ST integrates a hardware I2C interface and a LIN (Local Interconnect Network) serial interface, supporting LIN 2.x protocol for automotive body electronics without an external transceiver. The LIN peripheral operates at data rates up to 20 kbps, and the I2C peripheral supports standard-mode (100 kbps) and fast-mode (400 kbps) for communicating with sensors, EEPROMs, and display controllers on shared 2-wire buses.
How much program and data memory does PIC16F1705-I/ST provide for firmware development?
PIC16F1705-I/ST provides 8192 words (approximately 14 KB) of Flash program memory and 1024 bytes of SRAM for runtime data storage. This memory size supports typical automotive LIN slave firmware stacks, including LIN stack protocol layers, analog signal processing routines, and diagnostic fault code storage, without requiring external memory expansion.
At what minimum supply voltage can PIC16F1705-I/ST run at 16 MHz, and how does this help in automotive designs?
PIC16F1705-I/ST operates at a minimum supply voltage of 2.3 V when clocked at 16 MHz, and at even lower voltages when the clock is reduced below 16 MHz. In automotive applications, the supply voltage on a 12 V vehicle bus can droop to 6 V to 9 V during cold crank events, and an LDO regulator outputting 3.3 V may droop transiently; the 2.3 V minimum ensures PIC16F1705 continues executing LIN bus keep-alive routines rather than resetting during these transient conditions.
How does PIC16F1705-I/ST in a 14-pin TSSOP compare to PIC16F1509 for a LIN slave node design?
PIC16F1705-I/ST in the 14-pin TSSOP integrates a hardware LIN peripheral directly, whereas PIC16F1509 in a 20-pin package lacks a dedicated LIN module and would require a software UART emulation to achieve LIN communication. For a compact LIN slave node with fewer than 10 GPIO pins needed, PIC16F1705 saves 6 pins and associated board space, reducing the PCB footprint by approximately 20% compared to the 20-pin SSOP alternative.
