NXP Semiconductors LPC1830FET180,551

Overview

LPC1830FET180,551 from NXP Semiconductors is a flashless 32-bit ARM Cortex-M3 microcontroller operating at up to 180 MHz, featuring 200 kB on-chip SRAM, dual high-speed USB interfaces (USB0 as Host/Device/OTG with on-chip HS PHY; USB1 as Host/Device with ULPI), and Ethernet MAC with IEEE 1588 support. It targets industrial control systems requiring deterministic real-time response, secure boot via ROM-based firmware, and external memory expansion via EMC.

For engineers reviewing the LPC1830FET180,551 datasheet, LPC1830FET180,551 pinout, LPC1830FET180,551 application, or LPC1830FET180,551 equivalent, key selection criteria include TFBGA180 package compatibility, absence of LCD controller (vs. LPC1850), 118 GPIO count, dual C_CAN 2.0B support, and RTC with battery-backed 256-byte registers for time-critical embedded logging.

Technical Context

The LPC1830FET180,551 implements an ARM Cortex-M3 r2p1 core with Harvard architecture, 3-stage pipeline, and integrated MPU supporting eight memory regions. Its clock system uses three independent PLLs: one for CPU (up to 180 MHz), one dedicated to USB0, and one configurable for audio applications.

Digital peripheral routing is managed by the Global Input Multiplexer Array (GIMA), enabling flexible event-driven interconnection between timers, SCTimer/PWM, ADCs, and GPIOs. The External Memory Controller (EMC) supports SRAM, NOR flash, and SDRAM with programmable timing, while the State Configurable Timer/PWM (SCTimer/PWM) subsystem provides deterministic PWM generation with match/capture and pattern-matching logic.

FAQ

What is the maximum operating frequency of the LPC1830FET180,551?

The LPC1830FET180,551 operates at a maximum CPU frequency of 180 MHz, achieved via its ARM Cortex-M3 core and triple PLL clock generation unit. This frequency is sustained under industrial temperature range (−40 °C to +85 °C) with proper power supply decoupling and thermal management per NXP's AN11122 guidelines. The LPC1830FET180,551 does not require external crystal above 25 MHz due to internal PLL multiplication.

Does the LPC1830FET180,551 include internal flash memory?

No, the LPC1830FET180,551 is a flashless microcontroller. It boots from external memory via Quad SPI Flash Interface (SPIFI) or UART/USB ISP using the 64 kB ROM bootloader. This architecture eliminates flash endurance limitations and enables secure, encrypted firmware updates directly to external SPI NOR/Quad-SPI flash. The LPC1830FET180,551 relies entirely on its 200 kB SRAM for runtime code and data storage.

How many USB interfaces does the LPC1830FET180,551 support, and what are their capabilities?

The LPC1830FET180,551 supports two high-speed USB 2.0 interfaces: USB0 functions as Host/Device/OTG with integrated on-chip high-speed PHY; USB1 operates as Host/Device with ULPI interface to an external high-speed PHY. Both include DMA support and ROM-resident USB stack components. USB0's integrated PHY eliminates external transceiver components, while USB1's ULPI interface enables flexible PHY selection for ESD-hardened or low-power variants. Neither interface supports USB 3.x.

What peripheral features distinguish the LPC1830FET180,551 from the LPC1850 variant?

The LPC1830FET180,551 omits the LCD controller present in the LPC1850, reducing pin count to 118 GPIOs (vs. 164) and eliminating associated display timing peripherals. It retains identical Ethernet, dual USB, dual C_CAN, EMC, SCTimer/PWM, and analog subsystems. This makes the LPC1830FET180,551 optimal for headless industrial gateways where display output is unnecessary, lowering BOM cost and PCB layer count without sacrificing core connectivity or control capabilities.

Can the LPC1830FET180,551 operate in low-power modes with RTC functionality active?

Yes, the LPC1830FET180,551 supports ultra-low-power RTC operation in Deep power-down mode, powered independently by a 3 V battery on the RTC power domain. In this state, the 256 bytes of battery-backed registers retain time/date/alarm settings, and the alarm timer can generate a wake-up interrupt. The main CPU and SRAM are fully powered down, achieving sub-1 µA quiescent current. Full RTC functionality-including timestamping and calendar operations-remains available upon wake-up without reinitialization.
