概要

Description

The PIC16F684-I/ST is an 8-bit microcontroller from Microchip’s PIC16F family, featuring a 14-pin TSSOP package. It operates at up to 20 MHz with a RISC architecture and includes:
- 4 KB Flash memory (program storage)
- 256 bytes of RAM & 256 bytes of EEPROM
- 12 I/O pins (with analog, PWM, and interrupt capabilities)
- Analog-to-Digital Converter (ADC) (10-bit, 8 channels)
- Comparators, PWM modules, and timers
Ideal for embedded control applications (e.g., sensors, motor control, consumer electronics), it supports low-power modes (nanoWatt tech) and In-Circuit Serial Programming (ICSP). Its compact size and robust peripheral set make it suitable for cost-sensitive, space-constrained designs.
Key strengths: Low cost, ease of use, and versatile I/O. Limitations: Limited memory for complex tasks.
For development, use MPLAB X IDE with PICkit programmers.
