C8051F127

C8051F12x/13x Analog-Intensive MCUs

The C8051F127 is a highly integrated mixed-signal 8-bit microcontroller (MCU) featuring a powerful 8051 core with 50 MHz performance. This analog-intensive MCU features a 10-bit, 8-ch., 100 ksps ADC, a 12-bit, 2-ch. DAC, and 2 comparators. The C8051F127 also offers 128 kB Flash, 8 kB RAM along with 5 x 16-bit timers and additional communication interfaces in a 10x10 mm, QFP64. With on-chip VDD monitor, Watchdog timer, a ±2 internal oscillator, and high analog integration, the C8051F127 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 fiber optic systems among others.
