C8051F021-GQR is a highly integrated mixed-signal 8bit microcontroller (MCU) featuring a powerful 8051 core with 25MHz performance. This analogue-intensive MCU features a 12bit, 8-ch., 100Ksps ADC, a 12bit, 2-ch. DAC, and 2 comparators. It also offers 64KB flash, 4.25KB RAM along with additional communication interfaces and 5 x 16bit timers in a 10x10 mm, QFP64 package. With on-chip VDD monitor, watchdog timer, a ±20 internal oscillator, and high analogue integration, this MCU is a truly stand-alone system-on-chip solution, making it ideal for applications such as portable medical equipment, weigh scales, test equipment, and fibre optic systems among others.
- Data-dependent windowed interrupt generator, built-in temperature sensor (± 3°C) SAR ADC
- Can synchronize outputs to timers for jitter-free waveform generation
- Two analogue comparators, voltage reference, precision VDD monitor/brown-out detector
- On-chip debug circuitry facilitates full- speed, NonIntrusive in-circuit/in-system debugging
- Pipelined instruction architecture; executes 70% of instruction set in 1 or 2 system clocks
- Hardware SMBus� (I2C� Compatible), SPI�, and two UART serial ports available concurrently
- External oscillator: crystal, RC, C, or clock, real-time clock mode using timer 3 or PCA
- Supply voltage range from 2.7V to 3.6V, typical operating current is 10mA at 20MHz
- Multiple power saving sleep and shutdown modes
- 64TQFP package, temperature rating range from -40°C to +85°C
