It features a vector floating-point coprocessor and 256 KB of on-chip SRAM with separate 32 KB instruction and data caches. The device integrates a rich peripheral set including 10\/100 Ethernet MAC, USB 2.0 OTG, LCD controller supporting STN and TFT displays up to 1024x768, dual NAND flash controllers, and an external memory controller for SDR\/DDR SDRAM. With seven UARTs, dual I2C, SPI\/SSP, and I2S interfaces, it is well-suited for complex embedded applications requiring Linux or advanced RTOS support.","working_principle":"The LPC3250FET296\/01 is centered around an ARM926EJ-S CPU core with a 5-stage Harvard pipeline and integral MMU supporting virtual memory for multi-programming operating systems. The VFP coprocessor handles IEEE 754 floating-point operations in hardware. A multi-layer AHB bus matrix provides separate buses for CPU instruction fetch, CPU data access, DMA controller, USB controller, LCD controller, and Ethernet MAC, minimizing arbitration delays. The external memory controller interfaces with SDR\/DDR SDRAM and static devices. Two NAND flash controllers support both SLC and MLC devices. The LCD controller has its own DMA engine for display refresh. The USB OTG controller includes a dedicated PLL for the 48 MHz USB clock. Power management includes stop mode with peripheral wake-up capability.","pin_description":"
