Microchip PIC16F1823T-I/SL 8-Bit Microcontroller: Data Sheet and Application Overview

The PIC16F1823T-I/SL is an 8-bit microcontroller from Microchip Technology, designed to deliver a compelling blend of performance, power efficiency, and integration in a compact package. As a member of the enhanced mid-range PIC16F182X family, it leverages the nanoWatt XLP technology for ultra-low power consumption, making it an ideal choice for a vast array of battery-powered and energy-sensitive applications.

Housed in a 14-pin SOIC package, this MCU is built around an enhanced 8-bit RISC CPU core operating at up to 32 MHz, offering 3.5 KB of Flash program memory and 128 bytes of RAM. A standout feature is its rich set of integrated peripherals, which significantly reduces external component count and simplifies design. Key among these are:

Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART): Facilitates robust serial communication (UART) for interfacing with PCs, modules, or other microcontrollers.

Serial Peripheral Interface (SPI) and Inter-Integrated Circuit (I²C): Two powerful serial communication protocols supported by dedicated modules (MSSP) for connecting to sensors, memories, and other peripherals.

Complementary Waveform Generator (CWG): This peripheral is critical for advanced control applications, generating complementary PWM signals with dead-band control for driving half-bridge and full-bridge circuits in motor control and power conversion.

10-bit Analog-to-Digital Converter (ADC): With up to 8 channels, it allows for precise measurement of analog signals from various sensors.

Multiple Timers and Comparators: Including 16-bit timers and analog comparators, providing the necessary tools for timing operations and real-time control.

The core's architecture, featuring a 16-level deep hardware stack and 49 instructions, ensures efficient operation. Its extreme low-power (XLP) capabilities are paramount, with sleep currents down to tens of nanoamps, enabling designs that can operate for years on a single battery.
