Microchip PIC16F18855-I/SP: A Comprehensive Overview

The Microchip PIC16F18855-I/SP is a versatile 8-bit microcontroller from the enhanced mid-range PIC16F1xxx family. Housed in a 28-pin SPDIP package, this device is engineered for applications requiring robust performance, high integration, and low power consumption. Its architecture is built around an enhanced 8-bit RISC CPU core that can operate at speeds up to 32 MHz, delivering a powerful 16 MIPS performance.

A key feature of this microcontroller is its rich set of peripherals designed to minimize external component count. It includes a 12-bit Analog-to-Digital Converter (ADC) with Computation (ADC2). This advanced ADC can perform signal processing in the background while the CPU sleeps, dramatically improving power efficiency in sensor-based applications. For control applications, it features multiple Capture/Compare/PWM (CCP) modules and a 5-bit Digital-to-Analog Converter (DAC).

Memory resources are substantial, with 14 KB of Flash program memory, 1 KB of RAM, and 256 Bytes of high-endurance EEPROM for critical data storage. The core is also supported by a Memory Access Partition (MAP) feature, which enhances application security and firmware upgradeability.

Connectivity is handled through EUSART, SPI, and I2C modules, providing flexible communication interfaces to other system components. For timing and control, it includes hardware timers, a Windowed Watchdog Timer (WWDT), and a Complementary Waveform Generator (CWG).

Operating from a wide voltage range of 1.8V to 5.5V, the PIC16F18855 is ideal for battery-powered and low-voltage systems. Its nanoWatt XLP technology ensures exceptionally low power consumption in active and sleep modes, making it perfect for power-sensitive designs.

ICGOODFIND: The PIC16F18855-I/SP is a highly integrated, feature-rich 8-bit MCU. Its combination of a powerful core, advanced analog peripherals like the computation ADC, and ultra-low power management makes it an excellent choice for a wide array of embedded designs, including automotive, industrial, consumer, and Internet of Things (IoT) applications.
