LPC5504JHI48QL

The LPC5504JHI48QL is an NXP microcontroller in the LPC5500 family built around an ARM Cortex-M33 core (Armv8‑M). It targets low‑power, secure embedded applications and includes Arm TrustZone for secure/non‑secure separation and a hardware cryptographic accelerator. It provides a broad peripheral set (GPIO, timers, PWM, ADC/DAC, I2C, SPI, UART, USB Full‑Speed, DMA, RTC) and on‑chip flash and RAM (sizes vary by variant). The 48‑pin JHI48QL package denotes the physical package. Typical uses include IoT edge nodes, sensor/actuator control, secure access devices, and other power‑efficient, crypto‑enabled embedded systems. Development is supported by NXP MCUXpresso SDK and ecosystem. Note: exact memory sizes and feature details vary by device option; consult the datasheet for this specific part.
