The 136K x 8 RAM supports multiple packet buffers and a decent heap for dynamic allocation. If your design runs a GUI on an external display, the EBI/EMI interface maps the frame buffer off-chip without stealing internal RAM. ## Connectivity and peripherals — one chip, many buses The motor control PWM and QEI inputs are wired for servo or BLDC drive feedback.","metaTitle":"NXP LPC4337JET256,551 ARM Cortex-M4/M0 MCU, 204MHz, 1MB Flash","metaDescription":"NXP LPC4337JET256,551 32-bit dual-core MCU with 204MHz speed, 1MB Flash, 136K RAM, Ethernet, CAN, USB OTG.
