Microchip PIC16F1947T-I/PT: A Comprehensive Technical Overview

The Microchip PIC16F1947T-I/PT represents a robust and versatile 8-bit microcontroller within Microchip's extensive PIC16F family. Housed in a 44-pin TQFP package, this device is engineered for applications demanding high performance, rich peripheral integration, and reliable operation in industrial, automotive, and consumer environments. Its core is based on an enhanced mid-range architecture with a 16-level deep hardware stack and 49 instructions, optimizing code efficiency and execution speed.

A standout feature of the PIC16F1947T-I/PT is its substantial memory configuration. It boasts 28 KB of self-read/write capable Flash program memory and 1024 bytes of RAM, providing ample space for complex application code and data handling. This is complemented by 256 bytes of high-endurance EEPROM data memory, ideal for storing critical parameters that must be retained through power cycles.

The microcontroller's peripheral set is exceptionally rich, designed to minimize external component count. It includes two Capture/Compare/PWM (CCP) modules and one Enhanced CCP (ECCP) module, offering advanced motor control and waveform generation capabilities. For analog interfacing, it integrates a 14-channel 10-bit Analog-to-Digital Converter (ADC) with auto-acquisition, enabling precise sensor data reading. Communication is facilitated through multiple serial interfaces: EUSART (for RS-232/485), SPI, and I2C, providing flexible connectivity options to other chips and systems.

Further enhancing its utility are dedicated hardware features like the Complementary Waveform Generator (CWG) and Numerically Controlled Oscillator (NCO), which offload complex timing tasks from the CPU. It also includes a Hardware Limit Timer (HLT) for robust safety-critical applications. Operating from 2.0V to 5.5V and across an industrial temperature range of -40°C to +85°C, the PIC16F1947T-I/PT ensures reliability in harsh electrical and environmental conditions.

ICGOODFIND: The PIC16F1947T-I/PT is a powerhouse of integration, offering a compelling blend of memory, advanced peripherals, and hardware-based functional safety features. It is an excellent choice for designers seeking a single-chip solution for sophisticated control systems, from industrial automation to advanced sensing nodes.
