At this frequency, the MCU can run a full Ethernet TCP/IP stack, a CANopen master, and a motor-control loop without saturating the CPU. The 136 KB SRAM provides enough working memory for dual Ethernet packet buffers (typically 16–32 KB each) and an RTOS heap, reducing the need for external SRAM in many designs. ## On-chip EEPROM and data converters 16 KB of EEPROM is available for calibration constants, configuration parameters, or fail-safe boot settings without wearing the main Flash. The analog subsystem includes an 8-channel 10-bit ADC and a single 10-bit DAC, sufficient for monitoring motor currents or setting an analog reference in a control loop.","metaTitle":"NXP LPC1857JET256,551 ARM Cortex-M3 MCU, 180 MHz, 1 MB Flash, 256-LBGA","metaDescription":"NXP LPC1857JET256,551 32-bit ARM Cortex-M3 MCU. 180 MHz core, 1 MB Flash, 136 KB SRAM, Ethernet, CAN, USB.
