The NXP LPC1549JBD100E is a 32-bit ARM Cortex-M3 MCU running at 72 MHz, with 256 KB Flash and 36 KB RAM. It integrates a 12-bit ADC with 24 channels, 76 I/O, and interfaces including CAN, USB, I2C, SPI, and UART.
For dual-sourcing resilience, the LPC1549 family includes multiple density and package variants sharing the same Cortex-M3 core and peripheral set.
Yes, the MCU includes both CAN and USB interfaces, along with I2C, SPI, and UART.
The datasheet covers the full electrical characteristics, pinout diagram, and timing for the 100-LQFP package. The base product number is LPC1549.
Within the LPC15xx series, other density and package options share the same Cortex-M3 core and peripheral set, allowing a pin-compatible drop-in for different memory or I/O requirements.
