180 MHz Cortex-M4 with 360 KB SRAM — no internal Flash
The NXP LPC54018JET180E is a 32-bit ARM Cortex-M4 single-core MCU running at 180 MHz, with 360 KB of on-chip SRAM and no internal Flash — program storage lives on external SPI Flash or parallel memory via the EBI/EMI interface. This ROMless architecture suits designs that boot from a serial NOR Flash (SPIFI) or an SD card, keeping the BOM flexible for code-size scaling without respinning the MCU. The 145 GPIO pins and rich peripheral set — Ethernet, dual USB, CAN, SDIO, I²S, and a 12-channel 12-bit ADC — target connected industrial controllers, HMI panels, and IoT gateways that need real-time control and protocol handling in a single chip.
180-TFBGA package — rework considerations
Hand rework is possible with a hot-air station and a stencil, but the ball pitch demands careful alignment and a clean pad surface.
