It targets industrial control, motor-drive, and communication-gateway applications where a single-chip MCU must handle both real-time loops and protocol stacks like Ethernet, CAN, and USB OTG without an external host processor. Supply range of 2 V to 3.6 V. ## 150 MHz Cortex-M3 — what it means for throughput At 150 MHz the Cortex-M3 delivers 150 MHz clock speed. The DMA engine offloads peripheral transfers. ## Memory sizing and field-update reality 1 MB of Flash holds a full firmware image plus a fallback bootloader for over-the-air or fieldbus-driven updates. The 136K x 8 SRAM leaves room for a TCP/IP buffer pool and a few kilobytes of real-time data without needing external RAM. The part integrates CAN, Ethernet, USB OTG, multiple I²C and SPI/SSP ports, plus a Motor Control PWM block with dead-time insertion. That means one MCU can act as a fieldbus gateway, a servo drive controller, and a data-logging node. The 16-channel 10-bit ADC and single 10-bit DAC handle analog feedback from current sensors or potentiometers. The 256-LBGA package is a standard ball-grid array. No last-time-buy or EOL notice is on record.","metaTitle":"NXP LPC1837FET256,551 ARM Cortex-M3 MCU, 150 MHz, 1 MB Flash","metaDescription":"NXP LPC1837FET256,551 32-bit ARM Cortex-M3 MCU, 150 MHz, 1 MB Flash, 136K x 8 RAM, -40°C to 85°C, 256-LBGA.
