150 MHz Cortex-M33 with industrial temperature range
The NXP LPC5534JBD100E is a 32-bit ARM Cortex-M33 single-core MCU clocked at 150 MHz, with 128 KB Flash and 96 KB RAM. The Cortex-M33 core brings TrustZone security isolation for partitioning trusted and non-trusted firmware regions — relevant if you are running a communications stack alongside safety-critical control code.
Flexcomm serial ports and mixed-signal peripherals
The Flexcomm interface is the notable peripheral here: each serial port can be configured as UART, I2C, SPI, I2S, or I3C without external level shifters or mux logic. That reduces BOM count on boards that need multiple protocol bridges. The part also carries 23×16-bit A/D channels and 2×12-bit D/A channels — enough analog front-end for a multi-sensor input stage without an external ADC. Connectivity includes CANbus and USB 2.0, so it fits into industrial fieldbus gateways or data-logging nodes that need to talk to both a CAN network and a host PC.
