That clock rate places it in the mid-range of the LPC3200 family — enough throughput for a real-time Ethernet stack with headroom for a control loop, but not the top-bin part if you need multiple protocol stacks or heavy DSP work. The 16/32-Bit core size means legacy 16-bit code lifts cleanly, but the compiler targets ARM mode for performance. At 266 MHz, expect bus timing to be the constraint on external memory access, not the core itself. ## ROMless with 256 KB SRAM — plan for external code storage This part has no internal Flash or ROM — program memory type is ROMless. The 256K x 8 SRAM is for data, not code. You must boot from external NOR Flash, NAND, or SRAM via the EBI/EMI interface. That means a companion memory chip on the BOM and careful PCB layout for the parallel bus. The 296-TFBGA (15x15 mm) package gives enough ball count for a wide external bus plus the peripheral I/O. ## Peripheral set for industrial and motor control The connectivity list is broad: Ethernet MAC, USB OTG, multiple SPI/SSP, I²C, UART/USART, plus IrDA and Microwire. The Motor Control PWM and general-purpose PWM, along with the DMA controller and the 3-channel 10-bit ADC, make this a natural fit for a servo drive or inverter control board that also needs an Ethernet fieldbus interface. The 51 general-purpose I/O are enough for a modest HMI or I/O bank, but not for a high-density PLC backplane. No LTB or obsolescence notice is on record.","metaTitle":"NXP LPC3240FET296/01551 ARM926EJ-S MCU, 266MHz, 256KB SRAM, 296-TFBGA","metaDescription":"NXP LPC3240FET296/01551 ARM926EJ-S MCU at 266MHz, 256KB SRAM, ROMless, Ethernet, USB OTG, motor PWM, -40°C to 85°C, 296-TFBGA.
