C8051F92x-93x Ultra Low-Power MCUs

The C8051F92x/3x low-power MCU family is the industry's first MCU family capable of full spec operation down to 0.9 V and up to 3.6 V, enabling single-cell battery operation as well as dramatically increasing battery life for dual-cell applications. With an integrated dc-dc converter, the C8051F92x/3x has been designed to provide a fast wake-up time, low active mode and ultra-low sleep mode current consumption.

The F9xx series has the industry’s lowest active mode current consumption, which saves power when the application is running. It also has the industry’s lowest current consumption in sleep modes, which is often the most common mode in many battery-powered applications. Also, since the MCU cannot do any useful processing until all of the digital and analog circuitry all fully settled and operational, the F9xx series offers the industry’s fastest wake-up and analog settling time.

Features

  • One-cell mode supports 0.9 to 1.8 V operation
  • Dual-cell mode supports 1.8 to 3.6 V operation
  • Integrated high-efficiency dc-dc boost converter
  • Integrated low drop out (LDO) voltage regulator
  • Multiple internal oscillators
  • Ultra-low current sleep mode and fast wake
  • 25 MHz, single-cycle 8051 compatible CPU with low active-mode current
  • Burst mode 10-bit ADC with internal fast start-up VREF
  • Up to 23 capacitive touch sense inputs
