C8051F381-GMR

C8051F381-GMR is a highly integrated automotive and industrial microcontroller (MCU) that is auto-grade qualified and tested to AEC-Q100 specification. It features a powerful 8051 core with 50MHz performance along with 64KB flash, 4.25KB RAM. This MCU also offers integrated communication interfaces and a 10-bit, 21-ch., 500Ksps ADC and 2 comparators in a 5x5 mm, QFN32 package. With enhanced communication peripherals and robust peripheral set, this is ideal for motor control, sensor interface, parking assistance, seat position and adjustment, fluid level monitoring, and other automotive/industrial applications.

• VREF from the external pin, internal reference, or VDD, built-in temperature sensor
• Two comparators, internal voltage reference, brown-out detector and POR circuitry
• Integrated clock recovery; no external crystal required for full-speed or low speed
• On-chip debug circuitry facilitates full speed, non-intrusive in-system debug (no emulator required)
• Voltages from 2.7 to 5.25V supported using on-chip voltage regulators
• Pipelined instruction architecture; executes 70% of instructions in 1 or 2 system clocks
• Hardware enhanced SPI™, two I2C/SMBus™, and two enhanced UART serial ports
• External osc: crystal, RC, C or clock (1 or 2 pin modes), can switch between clock source on-the-fly
• Temperature rating range from -40 to +85°C
