C8051F581-IQR 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 128KB flash, 8KB RAM. This MCU also offers integrated communication interfaces and a 12bit, 32-channel, 200Ksps ADC and 3 comparators in a 7x7 mm, QFP48 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 on-chip VREF, external pin or VDD, internal or external start of conversion source
- Programmable hysteresis and response time, configurable as interrupt or reset source comparator
- On-chip debug circuitry facilitates full speed, nonintrusive in-system debug (no emulator required)
- Supply voltage range from 1.8 to 5.25V, typical operating current is 15mA at 50MHz
- Pipelined instruction architecture; executes 70% of instructions in 1 or 2 system clocks
- LIN 2.1 controller, no crystal required
- External oscillator: crystal, RC, C, or clock (1 or 2 pin modes)
- Can switch between clock sources on-the-fly; useful in power saving modes
- Temperature rating range from -40 to +125°C
