Microchip PIC16F723AT-E/SS 8-Bit Microcontroller Technical Overview and Application Guide
The Microchip PIC16F723AT-E/SS is a powerful member of the versatile PIC16F7xx family of 8-bit microcontrollers. Engineered for a broad spectrum of embedded control applications, this device combines a high-performance CPU core with a rich set of integrated peripherals, all within a compact and robust 28-pin SSOP package. Its architecture is built around an enhanced mid-range core, featuring a deep hardware stack and a large set of instructions, enabling efficient and compact code generation.
At the heart of the PIC16F723A lies an 8-bit RISC CPU capable of operating at up to 20 MHz, delivering a performance of 5 MIPS. This speed ensures responsive real-time control for a variety of tasks. The microcontroller is equipped with 14 KB of self-programmable Flash memory for application code storage and 368 bytes of SRAM for data handling, providing ample space for complex programs and variables.
A standout feature of this MCU is its sophisticated peripheral set. It includes a CCP (Capture/Compare/PWM) module and an Enhanced CCP (ECCP) module, which are essential for precise motor control, power conversion, and signal generation. The ECCP offers multiple PWM modes, including half-bridge and full-bridge drive signals, making it ideal for controlling brushed DC and stepper motors. Furthermore, it integrates a 12-channel, 10-bit Analog-to-Digital Converter (ADC) with automatic acquisition timing, allowing for accurate sampling of multiple analog sensors.
For communication and system expansion, the PIC16F723A offers multiple serial interfaces. It includes MSSP (Master Synchronous Serial Port) modules that can be configured to operate in either SPI (Serial Peripheral Interface) or I²C (Inter-Integrated Circuit) modes, facilitating communication with a vast ecosystem of sensors, memories, and other peripherals. An Addressable USART (AUSART) is also onboard, supporting both asynchronous (RS-232, RS-485) and synchronous serial communication protocols.
The device is designed for robustness and operational stability. It incorporates a suite of on-chip precision oscillators, including an 8 MHz internal oscillator, which can reduce external component count and system cost. Enhanced hardware-level Brown-out Reset (BOR) and Watchdog Timer (WDT) features ensure reliable operation in electrically noisy environments and prevent software lock-ups.
