The NXP LPC54605J512BD100K is a 32-bit ARM Cortex-M4 MCU from the LPC546xx series, clocked at 180 MHz. It carries 512 KB of Flash for program storage, 200 KB of SRAM for real-time data, and 16 KB of EEPROM for parameter retention — enough to run a moderate control loop, a USB stack, and a Modbus or CANopen protocol layer without external memory. 64 I/O lines and a 12-channel 12-bit SAR ADC are available.
The LPC54605J512BD100K is rated for -40°C to 105°C, making it suitable for industrial and automotive auxiliary applications.
Both are LPC546xx family MCUs with the same core and package. The LPC54606J512BD100 typically offers additional peripherals or memory — check the specific datasheet comparison for the exact delta in features like USB controller count or SRAM size.
The core runs at 180 MHz, which is the maximum clock for this Cortex-M4 implementation in the LPC546xx series.
