Microchip PIC16F1847-I/SS: An Integrated 8-Bit Microcontroller for Embedded Control Applications

The Microchip PIC16F1847-I/SS stands as a quintessential component in the realm of embedded systems, offering a robust and highly integrated solution for a vast array of control-oriented applications. As part of the enhanced mid-range PIC16F family, this microcontroller (MCU) combines a powerful core with a rich set of peripherals, all engineered to simplify design complexity and reduce system cost.

At its heart lies an 8-bit RISC CPU capable of operating at speeds up to 32 MHz, delivering a performance of 8 MIPS. This processing power is adept at handling numerous real-time control tasks. A significant feature is its Enhanced Mid-Range Core with 49 Instructions, which includes a hardware multiplier, significantly accelerating mathematical computations common in control algorithms.

A key strength of the PIC16F1847 is its exceptional peripheral integration, designed to create more self-sufficient systems with fewer external components. This includes:

Complementary Waveform Generator (CWG): This peripheral is critical for advanced motor control and power conversion applications, generating non-overlapping PWM signals to drive half-bridge and full-bridge circuits safely and efficiently.

Hardware-Based Capacitive Voltage Divider (CVD): This technology enhances touch sensing capabilities, allowing for the implementation of robust touch interfaces even in noisy environments, which is a marked advantage for consumer appliance controls.

Multiple Communication Interfaces: It is equipped with EUSART (for RS-232/485), SPI, and I2C modules, providing flexible options for system connectivity and communication with sensors, memory, and other peripherals.

Analog Integration: The MCU features a 10-bit ADC with up to 17 channels and two comparators, enabling direct interfacing with a wide range of analog sensors without external signal conditioning ICs.

The device also incorporates nanoWatt XLP Technology, enabling it to operate in extremely low-power modes. This makes the PIC16F1847-I/SS perfectly suited for battery-powered and energy-harvesting applications where power conservation is paramount.

Housed in a 28-SSOP package, this MCU offers a compact footprint for space-constrained designs. Its -40°C to +85°C industrial temperature range ensures reliable operation in harsh environments, broadening its applicability from industrial automation and automotive subsystems to consumer electronics and Internet of Things (IoT) edge nodes.

ICGOODFIND: The PIC16F1847-I/SS from Microchip is a highly capable and versatile 8-bit microcontroller. Its standout value lies in its integration of specialized peripherals like the CWG and CVD, which directly address the needs of modern embedded control, reducing component count, power consumption, and development time. It is an optimal choice for designers seeking a cost-effective, all-in-one solution for sophisticated control tasks.
