NXP adds Arm Cortex-M33-based LPC551x/S1x microcontroller family
NXP Semiconductors has extended its LPC5500 microcontroller family, with the release of the LPC551x/S1x family. The LPC551x/S1x microcontrollers are low power devices with embedded security and pin-, software- and peripheral-compatibility to accelerate time-to-market. The LPC551x/S1x family is based on 40nm flash technology.
The LPC551/S1x scores over 600 EEMBC CoreMarks and operates at down to 32 microA/MHz. It has a 15 MHz Arm Cortex-M33 core and up to 256kbyte on-chip flash and up to 96kbyte SRAM.
Other features are CAN FD / CAN 2.0 with MCUXpresso-based software and a dual-USB with on-chip PHY, supporting both HS and FS modes.
The LPC551/S1x has SDIO and up to nine FlexComm interfaces which are configurable as either SPI, I2C, I2S or UART.
Security features include SRAM PUF-based device root key with added application key storage options and secure boot and anti-rollback protection, together with Arm TrustZone technology for resource isolation. There is also a hardware block cipher (Prince) for encryption/decryption of internal flash and accelerators for symmetric and asymmetric cryptography.
The LPC551x/S1x is available in a choice of HLQFP100, VFBGA98 and HTQFP64 packages. All devices are supported by NXP’s MCUXpresso suite of software and tools.
The LPC551x/S1x MCU family is available now from NXP and its distribution partners.
There is an LPC55S16-based development board also available and third party support via the Arm ecosystem.
