The NXP LPC1830FBD144K is a 32-bit ARM Cortex-M3 microcontroller running at 180 MHz, part of the LPC18xx series. The device is housed in a 144-LQFP package with 83 I/Os and operates over the industrial temperature range of -40°C to 85°C on a 2.2 V to 3.6 V supply. This MCU is designed for industrial control, networking gateways, and motor-drive applications where a combination of real-time processing, wired connectivity, and external memory expansion is required. The ROMless architecture means program code must reside in external Flash or SRAM, accessed via the EBI/EMI or SPI interfaces.
The 180 MHz clock rate on this Cortex-M3 core provides enough throughput for protocol stacks (Ethernet TCP/IP, CANopen) and control loops without external cache. The 200K x 8 RAM supports moderate-sized buffers for Ethernet frames and data logging; designs that need larger code or data stores will use the EBI/EMI to attach external SDRAM or NOR Flash.
Connectivity set — Ethernet, CAN, USB OTG, and EBI/EMI
The LPC1830FBD144K includes an Ethernet MAC, two CAN controllers, USB OTG (Host/Device), and an external bus interface. The EBI/EMI can connect parallel NOR Flash, SRAM, or an LCD controller without an external bridge chip.
