Product details
Overview
LPC1830FET256K 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 2.0 interfaces (one with integrated HS PHY), 10/100T Ethernet MAC with IEEE 1588 support, and an external memory controller - deployed in industrial gateways requiring deterministic real-time control and multi-protocol connectivity.
For engineers reviewing the LPC1830FET256K datasheet, LPC1830FET256K pinout, LPC1830FET256K application, or LPC1830FET256K equivalent, this page delivers verified functional scope, validated package mapping, confirmed peripheral availability (no LCD, no C_CAN), and precise pin-level circuit roles for LBGA256 implementation.
Technical Context
The LPC1830FET256K implements a Harvard-architecture ARM Cortex-M3 core with 3-stage pipeline, integrated MPU and NVIC, and speculative branch prefetching - enabling deterministic interrupt latency and memory-protected task isolation in safety-aware firmware. Its clock system uses three independent PLLs: one for CPU (up to 180 MHz), one dedicated to USB0, and one configurable as audio PLL.
Digital subsystems include a State Configurable Timer/PWM (SCTimer/PWM) with event-driven state transitions, Global Input Multiplexer Array (GIMA) for flexible peripheral signal routing, and eight-channel GPDMA supporting AHB and APB peripherals - all accessible without CPU intervention for low-latency sensor-to-actuator paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3 r2p1, 180 MHz max - enables hard real-time execution with <10 µs worst-case interrupt response under MPU-protected context switching. |
| SRAM | 200 kB distributed across multiple AHB-accessible blocks - supports concurrent code execution, DMA buffers, and Ethernet packet staging without contention. |
| USB Interfaces | USB0: HS Host/Device/OTG with on-chip HS PHY; USB1: HS Host/Device with ULPI interface - allows dual-role USB connectivity while isolating PHY power domains. |
| Ethernet | 10/100T MAC with RMII/MII, DMA, and IEEE 1588-2008 v2 timestamping - delivers sub-microsecond time synchronization for industrial motion control networks. |
| Analog Peripherals | Two 10-bit ADCs (400 kS/s each, 8 channels total); one 10-bit DAC (400 kS/s) - supports simultaneous analog acquisition and waveform generation for closed-loop motor control. |
| Memory Interface | External Memory Controller (EMC) supporting SDRAM, NOR flash, SRAM, and ROM - enables boot-from-external-memory designs and expandable data logging buffers. |
| GPIO | 164 pins with AHB-mapped registers, DMA support, and group-interrupt capability - permits high-speed bit-banging, encoder quadrature decoding, and wake-up from deep power-down via programmable pin patterns. |
Pinout & Package
Package: LBGA256 (Plastic low profile ball grid array; 256 balls; body 17 × 17 × 1 mm; SOT740-2). Pin functions are multiplexed across 16 GPIO ports (P0–P9, PA–PF), with each pin supporting up to eight digital functions configured via SCU registers. Dedicated EMC, USB, Ethernet, and I2S signals occupy fixed ball positions per Figure 2 of the datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P1_15 | ENET_RXD0 | Ethernet receive data line 0 (RMII/MII) - must be routed with controlled impedance (50 Ω) and length-matched to other RMII signals for 50 MHz timing compliance. |
| P1_18 | ENET_TXD0 | Ethernet transmit data line 0 (RMII/MII) - requires series termination and tight trace matching to ENET_TXD1 and ENET_TX_EN for jitter-free 100 Mbps operation. |
| P1_19 | ENET_TX_CLK / ENET_REF_CLK | Reference clock input for RMII (50 MHz) or MII (25 MHz) - connects directly to crystal oscillator or PHY clock output; no internal division. |
| P1_20 | ENET_TXD1 | Ethernet transmit data line 1 (RMII/MII) - part of 2-bit RMII data bus; critical for full-duplex throughput and must avoid coupling with USB or high-speed digital traces. |
| P2_0 | USB0_PPWR | VBUS drive control for USB0 port (active HIGH) - polarity inverted vs. legacy LPC parts; requires external pull-down at reset to disable power switch. |
| P2_1 | USB0_PWR_FAULT | Overcurrent fault indicator (open-drain) - monitors external USB power path; asserts LOW during overcurrent, triggering host-side fault handling. |
Key Features
| Feature | Design Value |
|---|---|
| State Configurable Timer/PWM (SCTimer) | Event-triggered state machine with 16 states and 16 outputs - replaces software-timed PWM generation with hardware-deterministic waveform synthesis for servo drive commutation. |
| Global Input Multiplexer Array (GIMA) | Dynamic crossbar routing of 32+ inputs (ADC triggers, timer captures, GPIO edges) to 16+ peripherals - eliminates fixed signal dependencies and enables runtime reconfiguration of sensor fusion pipelines. |
| Dual High-Speed USB with PHY separation | USB0 integrates HS PHY; USB1 uses ULPI to offload PHY complexity - reduces BOM cost for USB0 while preserving design flexibility for USB1 PHY selection (e.g., USB334x). |
| IEEE 1588-2008 v2 Ethernet timestamping | Hardware-accelerated PTP frame timestamping with nanosecond resolution - enables precise time-of-arrival capture for synchronized distributed I/O in PLC backplanes. |
| Ultra-low power RTC domain | 256 bytes battery-backed registers + alarm timer on isolated 3 V supply - maintains timekeeping and wake-up scheduling during deep power-down (<1 µA quiescent current). |

FAQ
Does the LPC1830FET256K include on-chip flash memory?
No, the LPC1830FET256K is a flashless microcontroller. It relies on external memory (via SPIFI or EMC) or on-chip SRAM for code execution. Boot is supported from SPI flash (via SPIFI), external NOR/SRAM/SDRAM (via EMC), or UART/USB ISP - with 64 kB ROM containing boot code and driver libraries. This architecture enables flexible firmware updates and eliminates flash endurance concerns in high-write-cycle applications.
What peripherals are disabled in the LPC1830FET256K compared to the LPC1850FET256?
The LPC1830FET256K omits the LCD controller and second C_CAN channel present in the LPC1850FET256. All other major peripherals - including 200 kB SRAM, dual USB 2.0 (USB0 with HS PHY, USB1 with ULPI), 10/100T Ethernet MAC with IEEE 1588, SCTimer/PWM, GIMA, EMC, dual 10-bit ADCs, and 10-bit DAC - are fully retained and functionally identical in the LPC1830FET256K.
How does the USB0_PPWR signal polarity differ on the LPC1830FET256K?
The USB0_PPWR signal on the LPC1830FET256K is active HIGH (driven HIGH to enable VBUS), which is inverted relative to earlier NXP LPC families. A pull-down resistor is required at reset to ensure the power switch remains disabled until firmware explicitly asserts USB0_PPWR. This prevents unintended VBUS activation during boot and aligns with USB compliance requirements for controlled power ramp-up.
Can the LPC1830FET256K support IEEE 1588 Precision Time Protocol in hardware?
Yes, the LPC1830FET256K's Ethernet MAC includes full IEEE 1588-2008 v2 hardware timestamping capability - capturing transmit and receive timestamps with nanosecond resolution in dedicated registers. This enables boundary clock and transparent clock implementations without CPU overhead, critical for time-sensitive networking in industrial automation and power distribution systems.
What is the maximum number of GPIO pins available on the LPC1830FET256K in LBGA256 package?
The LPC1830FET256K provides up to 164 GPIO pins in the LBGA256 package, mapped across 16 ports (P0–P9, PA–PF). Each pin supports multiple functions (e.g., UART, I2C, SSP, ADC) configured via SCU registers. GPIO registers reside on the AHB bus for single-cycle access, and all ports support DMA transfers and group-interrupt triggering based on programmable input patterns.
