C8051F54x Automotive & Industrial MCUs

The C8051F54x automotive and industrial MCUs are available in small form factor packages from 24-pin (4 mm x 4 mm) to 32-pin (5 mm x 5 mm). This makes these microcontrollers ideal for applications that need to pack a significant amount of performance (50 MIPS) and integration (12-bit ADC) into a constrained space. Pin-for-pin compatibility exists between the C8051F54x series and the C8051F58x/59x series, the C8051F55x/56x/57x series and the C8051F50x/1x series.

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.
