NXP LPC55S16JBD64E is a 32-bit ARM Cortex-M33 single-core microcontroller from the LPC55S1x series, clocked at 150 MHz.
150 MHz Cortex-M33 — what the speed buys
The 150 MHz Cortex-M33 core handles real-time control loops and protocol stacks (USB, CAN). TrustZone isolates a secure bootloader without a second chip.
Memory and connectivity — fitting the BOM
256 KB Flash and 96 KB RAM support a moderate firmware image with a real-time OS, a USB stack, and a CANopen node. The Flexcomm interface can be reconfigured as an additional SPI, I²C, or UART — useful when the board needs one more serial port than the dedicated pins provide. The 10-channel 16-bit SAR ADC covers analog sensing without an external converter. Watch the 36 I/O count against your pin budget; the 64-HTQFP exposed pad helps thermal dissipation if the MCU drives multiple peripherals continuously.
