C8051F52xA/53xA Automotive & Industrial MCUs

C8051F52xA/53xA Automotive Microcontroller

The C8051F52xA/53xA automotive and industrial MCUs are the smallest sized automotive-grade MCUs on the market with a high level of integration (12-bit ADC and 0.5% precision oscillator) in a tiny 3 mm x 3 mm or 4 mm x 4 mm package.

With on-chip Voltage Regulator, Power-On Reset, VDD monitor, Watchdog Timer and clock oscillator, the Automotive Microcontrollers, including the C8051F54x devices, are truly stand-alone System-on-a-Chip solutions. The Flash memory can be reprogrammed even in-circuit, providing non-volatile data storage, and also allowing field upgrades of the 8051 firmware. User software has complete control of all peripherals, and may individually shut down any or all peripherals for power savings. More...

Automotive and Industrial MCUs

All Automotive microcontroller devices are designed to operate across the full automotive temperature (–40 to 125 ºC) and voltage (1.8 to 5.25 V) range. The C8051F5xxA Industrial and Automotive microcontroller family is the first to combine a ±0.5% integrated precision internal oscillator with 8 kB Flash, 25 MIPS, 12-bit ADC, dedicated LIN 2.1 controller, 16-bit timers/PWM, SPI, UART and six I/O lines in a small 3 mm x 3 mm, 10-pin DFN package. The C8051F53xA (-A and -I) family has the same feature set, but adds ten additional I/O lines and is offered in 20-pin QFN and TSSOP packages. Both families integrate additional analog features such as a programmable comparator, voltage regulator and on-chip temperature sensor to further reduce design complexity. This highly integrated architecture enables automotive electronics designers to simplify the design process and reduce system cost. All package options are lead-free, RoHS compliant and are qualified to AEC-Q100.

Highest Functional Density

These mixed-signal MCUs combine a high-speed 8051 CPU, Flash memory, best-in-class analog peripherals and digital signal processing in ultra-small packages, enabling full operational specification across the entire automotive voltage and temperature range with no design trade-offs. These Automotive microcontrollers offer the highest functional density of any available 8-bit automotive MCU.

Dedicated LIN 2.1 Controller

The LIN hardware implementation offers advantages over competing UART or software implementations. The dedicated message buffer and hardware generated flow control timing results in higher overall system bandwidth. The standard register-based control interface simplifies communication software development and minimizes code size.

Ultra-Precision Oscillator (±0.5%)

With ±0.5% tolerance across temperature (–40 to 125 ºC) and voltage (1.8 to 5.25 V), these Automotive MCUs offer a fully integrated LIN 2.1 master-mode implementation without any external timing components. The ultra-precision internal oscillator is configured to maximum instruction clock (25 MHz), resulting in no compromise between using an internal oscillator and achieving maximum CPU bandwidth.

Comprehensive Development Tools

The easiest way to begin development with the C8051F5xxA Automotive microcontroller family is with the fully functional “out-of-the-box” C8051F530ADK development kit, which includes all hardware and software required to begin application development. Additionally, the USB ToolStick platform is a fully contained evaluation and development system that includes a C8051F530A daughter card that enables the user to prototype a design and connect it directly into an existing LIN bus.
