The Microchip PIC16F723AT-I/SS is a high-performance, 8-bit microcontroller engineered for embedded control applications requiring a blend of processing power, peripheral integration, and cost-effectiveness. As part of Microchip's extensive PIC16F family, this device is built on an enhanced mid-range core with a 16-level deep hardware stack and 49 instructions. Its robust architecture and versatile feature set make it a compelling choice for a wide array of industrial, automotive, and consumer applications.
Core Architecture and Memory
At its heart, the PIC16F723AT-I/SS operates at speeds up to 20 MHz, delivering a performance of 5 MIPS. It is equipped with 14 KB of self-read/write capable Flash program memory and 368 bytes of RAM, ensuring ample space for complex firmware and data handling. The inclusion of 256 bytes of EEPROM data memory provides critical non-volatile storage for application parameters without requiring external components.
Advanced Peripheral Integration
A key strength of this microcontroller is its rich suite of integrated peripherals, designed to minimize external part count and system cost.
Analog Capabilities: It features a 10-bit Analog-to-Digital Converter (ADC) with up to 12 channels, enabling precise measurement of multiple analog signals. Two analog comparators with programmable reference voltage further enhance its analog interface capabilities.
Timing and Control: The device includes two Capture/Compare/PWM (CCP) modules and one Enhanced CCP (ECCP) module. These are essential for generating precise timing waveforms, controlling motors (particularly brushed DC motors via the ECCP's half-bridge and full-bridge modes), and measuring external signal timing.
Communication Interfaces: For system connectivity, it offers both SPI and I2C™ (Master/Slave) serial communication ports, allowing for easy interfacing with sensors, memory chips, and other peripherals. An Enhanced Addressable Universal Synchronous Asynchronous Receiver Transmitter (EUSART) supports serial communication protocols like RS-232 and RS-485.

Robust I/O Structure: With 35 I/O pins, all of which are programmable with pull-up resistors and featuring high sink/source current capabilities, the microcontroller can directly drive LEDs and other components.
