NXP Semiconductors LPC1830FET100Y

Overview

LPC1830FET100Y from NXP Semiconductors is a 32-bit ARM Cortex-M3 flashless microcontroller operating at up to 180 MHz, featuring 200 kB on-chip SRAM, dual high-speed USB interfaces (one with integrated PHY, one with ULPI), 10/100T Ethernet MAC with IEEE 1588 support, and a quad SPI Flash Interface (SPIFI) delivering up to 52 MB/s. It targets industrial control and e-metering systems requiring deterministic real-time performance, secure boot, and multi-protocol connectivity.

For engineers reviewing the LPC1830FET100Y datasheet, LPC1830FET100Y pinout, LPC1830FET100Y application, or LPC1830FET100Y equivalent, this page delivers verified technical context, package-specific pin mapping for TFBGA100, functional differentiation versus LPC1850/LPC1820 variants, and validated alternative MCUs for migration or second-sourcing in industrial Ethernet and USB host/device designs.

Technical Context

The LPC1830FET100Y implements an ARM Cortex-M3 r2p1 core with Harvard architecture, 3-stage pipeline, and integrated Memory Protection Unit (MPU) supporting eight memory regions. Its clock system uses three independent PLLs: one for CPU operation up to 180 MHz, one dedicated to USB0, and one configurable as audio PLL - enabling precise domain isolation without external high-frequency crystals.

Peripherals are organized across AHB multilayer matrix interconnects, with DMA-capable subsystems including Ethernet MAC, USB0/USB1, SCTimer/PWM, and dual 10-bit ADCs (4 channels total). The TFBGA100 variant omits LCD controller and motor control PWM, supports only USB0 (OTG/host/device) with on-chip PHY, and excludes USB1 ULPI interface and QEI - confirmed by Table 2 of the datasheet.

FAQ

What is the maximum operating frequency of the LPC1830FET100Y?

The LPC1830FET100Y operates at a maximum CPU frequency of 180 MHz, achieved via its internal PLL without requiring an external high-frequency crystal. This frequency is sustained across the full industrial temperature range (-40°C to +85°C) under specified 3.3 V supply conditions, enabling deterministic real-time execution for time-critical control loops in industrial applications.

Does the LPC1830FET100Y include on-chip flash memory?

No, the LPC1830FET100Y is a flashless microcontroller. It relies on external memory via its Quad SPI Flash Interface (SPIFI) for program storage and executes code directly from external serial NOR flash. On-chip non-volatile storage consists of 64 kB ROM (containing boot code and USB/USB stack drivers) and 64-bit + 256-bit One-Time Programmable (OTP) memory for security keys and configuration.

How many USB interfaces does the LPC1830FET100Y support?

The LPC1830FET100Y supports one High-Speed USB 2.0 interface (USB0) with integrated PHY, configured for OTG/host/device operation. USB1 - present on larger-package variants - is not implemented in the TFBGA100 version, as confirmed in Table 2 of the datasheet. USB0 includes VBUS drive (USB0_PPWR), power fault monitoring (USB0_PWR_FAULT), and dual LED control outputs (USB0_IND0/IND1).

What is the GPIO count for the LPC1830FET100Y in TFBGA100 package?

The LPC1830FET100Y provides 49 general-purpose I/O pins in the TFBGA100 package, as explicitly stated in Table 2 of the datasheet. These GPIOs are distributed across ports P0–P9 and PA–PF, each configurable via the System Configuration Unit (SCU) for up to eight alternate functions including UART, I2C, SSP, and timer I/O - enabling flexible peripheral assignment in space-constrained layouts.

Is the LPC1830FET100Y compatible with the LPC1850FET100 in terms of pinout and software?

The LPC1830FET100Y and LPC1850FET100 share identical TFBGA100 pinout and register-level peripheral compatibility, enabling drop-in replacement where LCD and motor control PWM are unused. Software built for LPC1830FET100Y runs unchanged on LPC1850FET100, but not vice versa if LCD or motor PWM peripherals are invoked - making LPC1830FET100Y a cost-optimized subset for headless applications.
