180 MHz Cortex-M4 with LCD and USB — HMI and control core
The NXP LPC54607J256BD208E is a 32-bit ARM Cortex-M4 MCU running at 180 MHz, with 256 KB Flash and 136 KB SRAM. It integrates a segment LCD controller, I²S audio interface, USB, and 12-bit ADC — making it a fit for industrial HMI panels, appliance displays, and IoT gateway nodes that need a single-chip display and connectivity engine. The 1.71 to 3.6 V supply range and -40 to 105°C temperature grade cover outdoor telecom and factory-floor enclosures without active cooling.
136 KB SRAM — buffer budget for LCD and USB
The 136 KB SRAM is sized for a QVGA frame buffer or multiple USB packet buffers without external memory. If your display resolution or data logging exceeds that, the DMA engine and peripheral bridge allow efficient burst transfers to the Flash — but watch the SRAM ceiling during concurrent LCD refresh and USB activity.
