Microchip PIC16F1704-I/SL: An Overview of the 8-Bit Enhanced Mid-Range Core Microcontroller
The Microchip PIC16F1704-I/SL is a powerful and versatile 8-bit microcontroller (MCU) from Microchip Technology's extensive PIC® MCU portfolio. Housed in a compact 14-pin SOIC package, this device is built around the robust Enhanced Mid-Range core with a Harvard architecture, offering a compelling blend of performance, peripheral integration, and cost-effectiveness for a wide array of embedded control applications.
At its heart, the PIC16F1704 operates at speeds up to 32 MHz, delivering a performance of 8 MIPS. It features 3.5 KB of program memory (Flash) and 128 bytes of RAM, providing sufficient resources for complex control algorithms and data handling. A key strength of this MCU lies in its advanced and specialized peripherals, which are designed to reduce system component count, lower overall design cost, and simplify firmware development.
One of the standout features of the PIC16F1704 is its integrated Complementary Waveform Generator (CWG). This peripheral is crucial for controlling brushless DC (BLDC) motors and other power conversion applications, as it can produce non-overlapping, complementary PWM signals with dead-band control, enhancing system safety and efficiency. Furthermore, the MCU includes a Numerically Controlled Oscillator (NCO), a precision timing peripheral that generates true linear frequency control, ideal for applications like frequency-based sensing or LED dimming.
The analog capabilities are equally impressive. The device is equipped with a 10-bit Analog-to-Digital Converter (ADC) with Capacitive Voltage Divider (CVD) technology, enabling advanced touch sensing interfaces without external components. It also includes two comparators and a 5-bit Digital-to-Analog Converter (DAC), providing flexible analog signal conditioning and monitoring on a single chip.
Communication is facilitated through EUSART, SPI, and I2C modules, ensuring easy connectivity with a vast ecosystem of sensors, displays, and other peripheral ICs. Enhanced core features like a 32 MHz internal oscillator, improved stack, and more direct addressing modes contribute to its efficiency and ease of use.
ICGOODFIND: The PIC16F1704-I/SL is an exceptional choice for designers seeking a high-integration, cost-optimized MCU for applications in motor control, lighting, consumer appliances, and Internet of Things (IoT) endpoints. Its unique blend of the Enhanced Mid-Range core, the CWG, NCO, and advanced analog peripherals makes it a powerhouse in a small form factor, enabling innovative and reliable designs.
