U14CF

U14CF is a microcontroller unit designed for embedded control applications. It is manufactured by ProtoTech Electronics and belongs to the Cortex‑M4 based family of devices. The core runs at a maximum clock frequency of 48 MHz and incorporates a floating‑point unit to accelerate mathematical operations in real‑time control loops. Flash memory capacity ranges from 128 kB to 512 kB, while data memory ranges from 20 kB to 32 kB, providing ample space for firmware and data buffers.

Key peripheral features of the U14CF series include multiple USART interfaces, CAN (Controller Area Network) transceivers, a high‑resolution analog‑to‑digital converter (ADC) with up to 12 bit resolution, and a 16‑channel digital‑to‑analog converter (DAC). The device also supports a range of real‑time communication protocols such as I²C, SPI, and UART, allowing it to interface with a wide variety of sensors and actuators. Timing functionality is provided by several advanced timers, PWM modules, and capture/compare units.

The U14CF incorporates a robust power management system. Low‑power sleep modes reduce power consumption to below 1 µA, making the device suitable for battery‑powered or energy‑harvesting installations. The package sizes vary between 48 pin LQFP and 64 pin BGA, providing options for both through‑hole and surface‑mount applications.

Industrial and medical device manufacturers have adopted the U14CF for its high performance, low power consumption, and reliability. In automotive sectors, the controller is used in powertrain management and infotainment systems. Several open‑source firmware projects support the U14CF, facilitating rapid development and deployment in hobbyist and educational contexts.
