The C8051F040 is a highly integrated mixed-signal 8-bit MCU featuring a powerful 8051 core with 25 MHz performance. This analog-intensive MCU features a 12-bit, 13-ch., 100 ksps ADC  and 3 comparators. The C8051F040 also offers 64 kB Flash, 4.25 kB RAM along with 5 x 16-bit Timers, additional communication interfaces and integrated CAN in a 14x14 mm, QFP100. With on-chip VDD monitor, Watchdog timer, a ±2 internal oscillator and high analog integration, the C8051F040 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.
