Product details

The LPC1549JBD64151 is an NXP 32-bit ARM Cortex-M3 MCU running at 72 MHz, with 256 KB Flash, 36 KB RAM, and 4 KB EEPROM on-chip. That Flash/RAM split handles a moderate control stack — say a CANopen node with a USB CDC virtual COM port — without external memory. The 44 I/O lines in a 64-LQFP package keep the board layout dense but routable on two layers for most industrial sensor or motor-interface designs.

The 24-channel 12-bit ADC samples enough analog inputs for a multi-axis sensor array. On-chip CANbus, USB, and multiple SPI/I²C/UART ports cover the common fieldbus and debug interfaces without external transceivers (aside from the CAN PHY and USB line driver).

Frequently asked questions

What is the LPC1549JBD64151's core speed and memory?

The MCU runs at 72 MHz with 256 KB Flash, 36 KB RAM, and 4 KB EEPROM — enough for a CAN/USB gateway or motor-control firmware without external storage.
