The 200 KB RAM supports moderate-sized frame buffers for the LCD controller or packet buffers for Ethernet — enough for a local HMI or a fieldbus gateway, but not for full video frame storage. ## Obsolete — sourcing reality for the LPC1850FBD208,551 NXP has marked this part as obsolete. ## Connectivity and I/O count The 142 GPIOs are in the 208-LQFP package. Supply range is 2.2 V to 3.6 V.","metaTitle":"NXP LPC1850FBD208,551 ARM Cortex-M3 MCU, 180 MHz, 200K RAM, 208-LQFP","metaDescription":"NXP LPC1850FBD208,551 32-bit ARM Cortex-M3 MCU, 180 MHz core, 200K x 8 RAM, Ethernet/USB OTG.
