NXP Semiconductors LPC3130FET180,551

Overview

LPC3130FET180 from NXP Semiconductors is a 180 MHz ARM926EJ-S microcontroller with integrated high-speed USB 2.0 OTG, 96 kB SRAM, NAND flash controller with 8-bit ECC, four-channel 10-bit ADC, and dual I2S/I2C interfaces - deployed in industrial HMI, medical data loggers, and embedded communication gateways requiring deterministic real-time response and low-power operation.

For engineers reviewing the LPC3130FET180 datasheet, LPC3130FET180 pinout, LPC3130FET180 application, or LPC3130FET180 equivalent, key selection criteria include its TFBGA180 package compatibility, 1.2 V core/1.8–3.3 V I/O voltage flexibility, dynamic clock gating for power domain control, and boot-from-NAND/SD/USB capability in resource-constrained designs.

Technical Context

The LPC3130FET180 implements an ARM926EJ-S core with Harvard-architecture 16 kB instruction and 16 kB data caches, MMU support for OS-based applications, and five-stage pipeline execution supporting both ARM and Thumb instruction sets. Its AHB/APB bus matrix enables concurrent peripheral access without CPU stalling.

System-level timing is managed by a programmable Clock Generation Unit (CGU) offering fractional clock synthesis from SYS_BASE and CLK1024FS_BASE domains, enabling precise audio master clocks (e.g., CLK_256FS_O) and configurable system clock outputs (SYSCLK_O). Power optimization leverages multiple independent supply domains (SUP1/SUP3/SUP4/SUP8) and dynamic clock gating across subsystems.

FAQ

What is the maximum operating frequency of the LPC3130FET180 CPU core?

The LPC3130FET180 features an ARM926EJ-S core rated for 180 MHz operation. This frequency is sustained under full load with proper thermal management and compliant 1.2 V core supply. The core clock may be dynamically scaled lower via the Clock Generation Unit to reduce power consumption during idle periods, and the AHB bus operates at 90 MHz - half the CPU frequency - ensuring balanced peripheral bandwidth.

Does the LPC3130FET180 support booting directly from NAND flash?

Yes, the LPC3130FET180 supports NAND flash boot via its integrated NAND controller with hardware ECC. Boot mode is selected using GPIO0–GPIO2 pins at reset; NAND boot requires configuration of EBI_A_0_ALE, EBI_A_1_CLE, and EBI_DQM_0_NOE signals. The ROM bootloader validates the first page's signature and loads initial firmware into SRAM before handing control to user code - eliminating need for external boot ROM.

How many independent I2S interfaces does the LPC3130FET180 provide?

The LPC3130FET180 provides two fully independent I2S interfaces: I2STX_0/I2SRX_0 and I2STX_1/I2SRX_1. Each includes dedicated transmit and receive data lines, bit clock, word select, and serial clock outputs. These operate concurrently with separate DMA channels, enabling simultaneous audio playback and recording - for example, feeding a codec's DAC and ADC paths independently without CPU intervention.

What are the voltage requirements for the LPC3130FET180's I/O banks?

The LPC3130FET180 separates I/O into three supply domains: SUP4 (1.65–1.95 V or 2.5–3.6 V) for NAND interface, SUP8 (same range) for SDRAM/LCD, and SUP3 (2.7–3.6 V) for USB/analog/peripherals. Core logic uses SUP1 (1.0–1.3 V). All I/O pins tolerate their respective domain voltages only - mixing 1.8 V and 3.3 V signaling on same bank violates electrical specs and risks latch-up.

Is the LPC3130FET180 pin-compatible with the LPC3131FET180?

Yes, the LPC3130FET180 and LPC3131FET180 share identical TFBGA180 pinout, package dimensions, and peripheral mapping. The sole functional difference is internal SRAM capacity: 96 kB in LPC3130FET180 versus 192 kB in LPC3131FET180. This makes LPC3131FET180 a drop-in upgrade for designs needing more RAM, with no PCB or firmware changes required beyond re-linking memory sections.
