Low-Power MCU Embeds Arm Cortex-M33

NXP Semiconductors has announced the availability of its LPC551x/S1x microcontroller (MCU) family, further extending its performance-efficient LPC5500 MCU series. The LPC551x/S1x MCU family offers developers low power consumption, embedded security, pin-, software- and peripheral-compatibility to accelerate time-to-market. The LPC551x/S1x family leverages ultra-efficient 40nm flash technology for cost and performance benefits.

Key features include:

  • Over 600 EEMBC CoreMarks and as low as 32uA/MHz
  • Up to 150MHz Arm Cortex-M33 core
  • Up to 256KB on-chip flash; up to 96 KB SRAM
  • CAN FD / CAN 2.0 with MCUXpresso-based software enablement
  • Dual-USB with on-chip PHY, supporting both HS and FS modes
  • SDIO and up to 9 FlexComm interfaces (configurable as either SPI/I2C/I2S,UART)
  • Advanced security enabled with MCUXpresso software and tools:
    • SRAM PUF based device root key with added application key storage options
    • Secure boot and anti-rollback protection
    • Arm TrustZone technology for resource isolation
    • Hardware block cipher (PRINCE) for encryption/decryption of internal flash
    • Accelerators for symmetric and asymmetric cryptography
    • Authenticated debug capabilities
  • Available in HLQFP100, VFBGA98 and HTQFP64 packages
  • LPC551x/S1x is fully supported by NXP’s MCUXpresso suite of software and tools

The LPC551x/S1x MCU family is available now from NXP and its distribution partners with a suggested resale price starting at $0.97 (USD) for 10,000-unit quantities of LPC5512JBD64. NXP is accompanying the silicon release with a LPC55S16-based development board at a suggested resale price of $41.18 (USD). Third-party support is allowed from the broad Arm ecosystem.
