Microchip AT89C51CC01CA-SLSUM: An 8-Bit Microcontroller with Integrated CAN Controller
The Microchip AT89C51CC01CA-SLSUM represents a powerful evolution in the classic 8051 microcontroller architecture, engineered to meet the demands of modern industrial and automotive control applications. This device stands out by integrating a robust Controller Area Network (CAN) controller directly onto its silicon, making it an ideal solution for networked systems requiring reliable, real-time communication.
At its core, this MCU features a high-performance 8-bit CPU capable of operating at clock speeds up to 32 MHz. It is built on a fully static design, which allows for operation down to zero frequency, enabling sophisticated power-saving modes. A significant enhancement over its predecessors is the inclusion of 16 KB of In-System Programmable Flash memory, which provides ample space for complex application code and offers the flexibility for field updates. This is complemented by 256 bytes of internal RAM and an additional 1 KB of XRAM, ensuring efficient data handling.
The hallmark of the AT89C51CC01CA-SLSUM is its integrated CAN 2.0B controller. This peripheral supports both 11-bit (standard) and 29-bit (extended) identifiers and is capable of operating at speeds up to 1 Mbit/s. It features 15 independent message objects with prioritized message handling, which simplifies the design of complex, multi-node networks typical in automotive body electronics or industrial machinery. This integration eliminates the need for an external CAN controller chip, reducing both system cost and board space.
Beyond its communication prowess, the microcontroller is equipped with a rich set of peripherals. It includes a 10-bit Analog-to-Digital Converter (ADC) with 8 input channels, perfect for sensor interfacing. For timing and control tasks, it offers Power-Frame PWM outputs, a 16-bit Programmable Counter Array (PCA), and standard timers/counters. It also features a full-duplex UART, enhancing its connectivity options for serial communication protocols.
Security and reliability are paramount. The device incorporates hardware-based security features like lock bits to protect proprietary firmware from being read or copied. Its operating voltage range of 2.7V to 5.5V and robust I/O design ensure stable performance in electrically noisy environments.

ICGOOODFIND: The Microchip AT89C51CC01CA-SLSUM is a highly integrated and cost-effective solution that successfully bridges the gap between the venerable 8051 core and the requirements of contemporary networked embedded systems. Its integrated CAN controller and comprehensive peripheral set make it exceptionally well-suited for applications in automotive networking, industrial automation, and building control.
