NXP LPC4300 series LPC4320FBD144,551 Dual-core ARM Cortex-M4F MCU
The LPC4320FBD144,551 is a high-performance, dual-core microcontroller from NXP Semiconductors, combining an ARM Cortex-M4F core (with FPU) and a Cortex-M0+ coprocessor for optimized real-time processing and power efficiency. Operating at up to 204 MHz, this MCU is designed for embedded applications requiring high-speed computation, DSP capabilities, and low-latency control, such as industrial automation, IoT gateways, and advanced motor control systems. The device features 1MB Flash memory and 264KB SRAM, with additional 128KB ROM containing bootloaders and USB drivers, ensuring robust firmware execution and quick system initialization.
TheLPC4320FBD144,551 integrates advanced peripherals, including a High-Speed USB 2.0 Host/Device/OTG controller, Ethernet MAC, CAN 2.0B, and multiple serial interfaces (UART, SPI, I2C, I2S) for versatile connectivity. Its configurable digital peripherals (State Configurable Timer, SCTimer/PWM) enable precise timing control for PWM-driven applications like LED dimming and servo control. The MCU supports external memory interfaces (SPI Flash, SDRAM, NOR/NAND Flash) via its EMC (External Memory Controller), allowing for expanded storage and high-speed data access.
With low-power modes (Sleep, Deep Sleep, Power Down, and Deep Power Down) and a dynamic voltage scaling (DVS) feature, the LPC4320FBD144,551 optimizes energy consumption for battery-powered devices. The hardware-based security includes AES-256 encryption and secure boot capabilities, protecting firmware integrity in sensitive applications. The device is housed in a 144-pin LQFP package, offering a balance of compact size and extensive I/O flexibility (up to 100 GPIOs). Its industrial temperature range (-40°C to +105°C) ensures reliable operation in harsh environments.
