The C8051F974-A-GMR is a microcontroller unit (MCU) from the 8051 family of silicon devices, the industry-standard 8-bit general-purpose MCU with an extended memory of 256K bytes. This specific device includes a public ROM, a public RAM and an RTC (Real Time Clock) module. It is also equipped with four UARTs as well as multiple communication and analog interfaces. This MCU is most suitable for use in automotive, industrial, medical and home automation applications.

The C8051F974-A-GMR is a low-power device, capable of operating at temperatures ranging from -55°C to 125°C. It is characterized by allowing multiple channels of sustained input/output (I/O) throughput, high performance and low power consumption. Additionally, it also provides a scalable selection of oscillator frequencies extending from 1MHz to 32MHz.

The C8051F974-A-GMR is a fully integrated system, with a wide range of capabilities and peripherals. This includes operating systems such as the C8051F-family products, which provide an easy-to-use, high-performance, real-time environment. This device also provides improved code density for the 8051 architecture, doubled by adding an extended data area, the XData area.

The C8051F974-A-GMR offers multiple communication ports, allowing flexible peripheral integration. These communication tools enable the device to receive and send data in real-time. It provides two UARTs (Universally Asynchronous Receiver-Transmitter) that are capable of transferring up to 8 data bits per frame and two LIN (Local Interconnect Network) ports. Additionally, it has two Pulse Width Modulation (PWM) ports that transmit a pulse with adjustable width on specified intervals.

A key feature of this MCU is its strong analog capabilities. This includes options such as an onboard, 10-bit SAR ADC (Successive Approximation Register Analog to Digital Converter) with up to 16 single-ended or 8 differential input channels, a Low power Wake-up Timer, RTC with integrated positive voltage regulator and built-in noise-resistant crystal. Furthermore, it supports up to 3 independent internal voltage references for precise analog signal control and conversion. This device also provides 32 external interrupt sources, making it suitable for high-speed signal processing.

The C8051F974-A-GMR is based on the 5T architecture, also known as Harvard architecture. This architecture is based on a Harvard law, which separates instructions and data memory. As a result, instructions are executed directly from program memory, while data is handled in separate SRAM memory. This architecture helps improve the speed and performance of the system, allowing faster data processing and more efficient overall operation.

The C8051F974-A-GMR is a highly integrated device with built-in hardware and software resources. It supports multiple software protocols such as I2C, LIN, UART, UPW, AES, SCI and SPI. Additionally, it also supports multiple operating systems, including the TinyRTOS, Real-Time Operating System (RTOS) embedded C and Atom. All of these features combine to provide the user with flexibility in design, allowing them to choose a combination of features to fit their specific application.

The C8051F974-A-GMR provides an ideal platform for home automation and medical applications. The device is also suitable for automotive and industrial applications, due to its low-power performance, robust design and capabilities. Overall, this device offers users a high degree of integration, reliability and flexibility.
