The 136K x 8 RAM (roughly 136 KB) is the working memory ceiling — enough for two full Ethernet frames (jumbo-sized) and a few hundred CAN message objects, but tight if you plan to run a heavy GUI or large audio buffers without external SDRAM. ## Industrial temperature range and package constraints The 256-LBGA (17x17 mm) package requires a multilayer PCB with blind/buried vias for signal breakout.","metaTitle":"NXP LPC1833FET256,551 ARM Cortex-M3 MCU, 150 MHz","metaDescription":"NXP LPC1833FET256,551 32-bit ARM Cortex-M3 MCU at 150 MHz with 512 KB Flash, 136K x 8 RAM, CAN/Ethernet/USB OTG, -40°C to 85°C.
