NXP Semiconductors Arm Cortex-M33 Microcontrollers
NXP Semiconductors’ LPC5500 series Arm® Cortex®-M33 Microcontrollers combine efficiency, functionality, and security supported by comprehensive enablement solutions, all optimized for low-cost IoT edge devices.
The Arm Cortex-M33 core operates at up to 100MHz and leverages the latest ARMv8-M architecture. It’s built on a low-power 40nm flash process with a current consumption of 32µA/MHz at 100MHz, and it’s offered with an optional second Cortex-M33 core to balance efficiency with performance.
The MCU also includes a tightly-coupled proprietary DSP accelerator and a cryptographic processor significantly improving efficiency. 640KB of flash and 320KB of SRAM are available, and the peripheral set includes high-speed USB plus PHY, 50MHz high-speed SPI, and dual SDIO interfaces. To maximize efficiency, the MCU also has an integrated PMIC, multiple low-power modes, and flexible peripheral power management.
The primary core of the MCU includes Arm TrustZone technology, which provides system-wide hardware isolation for trusted software. Secure and non-secure context switching is performed in hardware, which results in faster switching than the software-based alternative and doesn’t compromise deterministic real-time response.
The device includes an SRAM physically unclonable function based root of trust and provisioning and real-time execution is possible from encrypted images stored in the internal flash. Additional security features include secure boot, secure debug, and acceleration for AES-256 and SHA-2.
The LPCXpresso55S69 development board is a rapid development platform for the LPC5500 series and is fully supported by NXP’s MCUXpresso software and tools. The board includes a microSD card slot, NXP accelerometer, and stereo audio codec with line-in and line-out. Hardware expansion is possible using the MikroBus interface and PMod compatible connectors.
