Microchip AT89C51CC03UAT-RLTUM: An 8-Bit Powerhouse with Integrated CAN and Flash Memory
The Microchip AT89C51CC03UAT-RLTUM stands as a robust and highly integrated member of the classic 8051 microcontroller family, engineered to tackle complex tasks in demanding embedded control environments. This device skillfully merges the well-established architecture of an 8-bit microcontroller with advanced communication peripherals, most notably a Controller Area Network (CAN) controller, making it an ideal solution for a vast array of industrial and automotive applications.
At its core, the microcontroller operates with an optimized 8051 CPU, delivering up to 20 MIPS of processing power at 20 MHz. This performance level is more than adequate for handling sophisticated real-time control algorithms and managing multiple system tasks efficiently. A significant onboard feature is its 64 KB of In-System Programmable (ISP) Flash Memory. This non-volatile memory allows for flexible firmware updates in the field without removing the chip from the circuit, significantly enhancing product lifecycle management and development agility. Complementing the Flash are 2 KB of EEPROM for storing critical data that must be retained after power cycles and 2 KB of RAM for volatile data operations.
The defining feature of this microcontroller is its integrated CAN 2.0B controller. This peripheral is essential for developing nodes in robust, distributed serial communication networks, which are the backbone of modern automotive systems (like body control modules) and industrial automation (such as sensor nodes and actuator controllers). The CAN controller supports both 11-bit and 29-bit identifiers, ensuring broad compatibility with various network protocols.
Beyond CAN, the device is packed with a rich set of additional peripherals that minimize the need for external components, reducing both system complexity and cost. These include:
Two UARTs for classic serial communication (RS-232, RS-485).
A 16-bit Programmable Counter Array (PCA) with capture/compare and PWM modes, perfect for motor control and waveform generation.
A 10-bit Analog-to-Digital Converter (ADC) with 8 input channels for interfacing with analog sensors.
SPI and I2C serial interfaces for communication with a plethora of peripheral chips like memories and sensors.
Watchdog Timer and Power Monitor circuitry to ensure system reliability and safe recovery from electrical disturbances or code malfunctions.
Housed in a compact TQFP-44 package, the AT89C51CC03UAT-RLTUM offers a high level of integration in a small form factor. Its extended temperature range and robust design make it suitable for harsh operating environments, solidifying its position as a reliable choice for designers.
ICGOOODFIND: The Microchip AT89C51CC03UAT-RLTUM is a highly integrated 8-bit MCU that excels in networked applications. Its powerful combination of a CAN controller, substantial ISP Flash memory, and a comprehensive suite of analog and digital peripherals provides a single-chip solution for building reliable and connected embedded systems in the automotive and industrial sectors.
