NXP Semiconductors MCX W23 Wireless Microcontrollers
NXP Semiconductors MCX W23 Wireless Microcontrollers supply connectivity solutions for IoT applications. The MCX W23 is a highly integrated, single-chip, ultra-low-power BLUETOOTH® Low Energy 5.3 wireless transceiver with embedded microcontroller and Flash. By implementing the integrated ultra-low-power radio and Flash, the MCX W23 delivers an extended battery lifetime. The device provides a cost-effective solution within a small area needed for body-worn/battery-powered sensors and actuator applications.
Enabled with the flexible buck and boost option of the DC-DC converter, the MCX W23 operates directly from an extensive range of batteries.
The MCX W23, focused on advanced security, is part of the Certified Edgelock Assurance program (SESIP Level 2/PSA Level 2).
