180 MHz Cortex-M4 with Ethernet and USB onboard
The NXP LPC54608J512BD208K is a 32-bit ARM Cortex-M4 MCU from the LPC546xx series, clocked at 180 MHz. It carries 512 KB of Flash program memory, 200 KB SRAM, and 16 KB EEPROM emulation — enough for a moderate-size firmware stack with field-upgrade headroom and non-volatile parameter storage.
Memory and peripheral mix — what it means for a BOM
512 KB Flash and 200 KB SRAM support FreeRTOS or bare-metal applications with a GUI buffer. 16 KB EEPROM emulation stores calibration constants without an external serial EEPROM.
