It directly determines how much headroom you have for real-time control loops, TCP/IP stack processing, or display refresh. At this speed, a single-cycle multiply or a 16-bit timer capture runs without stalling the CPU — useful when the part is handling both a CANopen stack and a PWM motor-control interrupt simultaneously. ## Memory sizing: 1 MB Flash, 136 KB RAM, 16 KB EEPROM The 1 MB Flash is enough for a dual-image firmware layout (bootloader + application) with room for a small file system. The 136 KB SRAM is split across multiple banks; it can hold a 640x480 frame buffer at 16-bit colour if you use the external bus for the display controller. ## Lifecycle and sourcing status No last-time-buy or end-of-life notice has been issued. The 256-LBGA package is surface-mount only.","metaTitle":"NXP LPC1857FET256,551 ARM Cortex-M3 MCU, 180 MHz, 1 MB Flash, 256-LBGA","metaDescription":"NXP LPC1857FET256,551 32-bit ARM Cortex-M3 MCU. 180 MHz core, 1 MB Flash, 136 KB RAM, Ethernet/USB OTG/CAN.
