C8051F121-GQR is a highly integrated mixed-signal 8bit microcontroller (MCU) featuring a powerful 8051 core with 100MHz performance. This analogue-intensive MCU features a 12bit, 8-ch., 100Ksps ADC, a 12bit, 2-ch. DAC, and 2 comparators. It also offers 128 kB Flash, 8KB RAM along with 5 x 16bit timers and additional communication interfaces in a 10x10 mm, QFP64 package. With on-chip VDD monitor, Watchdog timer, a ±2 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
- Can synchronize outputs to timers for jitter-free waveform generation
- Two analogue comparators, voltage reference, VDD monitor/brown-out detector
- On-chip debug circuitry facilitates full-speed, nonintrusive in-circuit/in-system debugging
- IEEE1149.1 compliant boundary scan, complete development kit
- 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
- Dedicated watchdog timer; bi-directional reset pin
- Flexible PLL technology, external oscillator: crystal, RC, C, or clock
- Temperature rating range from -40 to +85°C
