MCX-C04x Active

Roll over image to zoom in

The MCX C04x microcontrollers, featuring an Arm® Cortex®-M0+ core, offer 32 KB Flash, 2 KB SRAM, and 8 KB boot ROM. Designed as entry-level MCUs, they prioritize simplicity and ease of use for a variety of applications. Key peripherals include a 12-bit ADC, comparator and multiple-channel timer/PWM modules. The enhanced low-power architecture ensures efficiency, with static power consumption as low as 2.2 μA and a 7.5 μs wake-up time for full retention. In deep sleep, static mode power consumption drops to just 77 nA. This series supports scalable memory options and flexible packaging, accommodating diverse application needs.

The MCX C04x series is supported by the MCUXpresso Developer Experience to optimize, ease and help accelerate embedded system development.

Features

Core Platform

  • Arm® Cortex®-M0+ @ 48 MHz

Performance with Low Power

  • Two times more CoreMarks®/mA than the closest 8/16-bit
  • Single-cycle fast I/O access port facilitates bit banging and software protocol emulation, maintaining an 8-bit ‘look and feel.’
  • Multiple, flexible low-power modes (including a new compute mode) that reduce dynamic power by placing peripherals in an asynchronous stop mode
  • LPUART, SPI, I²C, ADC, LP timer support low-power mode operation without waking up the core

Memory

  • 8 KB ROM with integrated bootloader
  • Security circuitry to prevent unauthorized access to RAM and flash contents

Advanced Analog

  • 12-bit SAR ADC with internal voltage reference, up to 818 ksps and 7 channels
  • 1.2 V high-accuracy internal voltage reference
  • High-speed comparator with internal 6-bit DAC

Timers

  • Two 2-channel Timer/PWM modules
  • Low-power timer allows operation in all power modes except for VLLS0
  • Real-time clock

Power and Operation

  • Temperature range: -40°C to 125°C (Tj)
  • IOs: 1.71 V to 3.6 V

Package Options

  • 16QFN: 3x3x0.65 mm, 0.5 mm pitch
  • 24QFN: 4x4x0.65 mm, 0.5 mm pitch
