NXP Semiconductors LPC4330FET180Y

Overview

LPC4330FET180Y from NXP Semiconductors is a dual-core ARM Cortex-M4/M0 microcontroller in a 180-ball TFBGA package, operating up to 204 MHz with 264 kB SRAM, dual high-speed USB (one with on-chip HS PHY), Ethernet MAC with IEEE 1588 support, and SCTimer/PWM subsystem - deployed in industrial motor control and embedded audio gateways.

For engineers reviewing the LPC4330FET180Y datasheet, LPC4330FET180Y pinout, LPC4330FET180Y application, or LPC4330FET180Y equivalent, this page delivers verified core architecture details, validated peripheral configurations, confirmed package-specific GPIO count (118 pins), and real-world timing and interface constraints for deterministic real-time system design.

Technical Context

The LPC4330FET180Y integrates an ARM Cortex-M4 main processor (204 MHz, FPU, MPU, ETM/ETB trace) with a fully independent ARM Cortex-M0 coprocessor (204 MHz, NVIC, JTAG/SWD), enabling asymmetric task partitioning - e.g., M4 handles Ethernet/USB protocol stacks while M0 manages real-time PWM generation or sensor preprocessing. Both cores share access to the AHB multilayer matrix but operate with separate local SRAM blocks (128 kB + 72 kB) and dedicated debug interfaces.

Its clock system uses three PLLs: one for CPU operation, one dedicated to USB0's high-speed PHY, and a third configurable as audio PLL; the 12 MHz IRC oscillator provides ±1.5% accuracy without external crystal dependency. The GIMA crossbar enables dynamic routing of 32+ event sources (timers, ADC, SCT) to 16+ destinations, supporting complex state-machine-driven I/O coordination without CPU intervention.

FAQ

What is the maximum operating frequency of the LPC4330FET180Y?

The LPC4330FET180Y operates at a maximum CPU frequency of 204 MHz for both its ARM Cortex-M4 and Cortex-M0 cores. This frequency is achieved using the internal PLL driven by the 12 MHz IRC oscillator or an external crystal (1–25 MHz). The dual-core architecture sustains full performance on both processors simultaneously without clock contention, as verified in NXP's LPC4350_30_20_10 Rev. 4.6 datasheet Section 2.

Does the LPC4330FET180Y include an integrated Ethernet PHY?

No, the LPC4330FET180Y integrates only the 10/100T Ethernet MAC with RMII and MII interfaces and IEEE 1588 time stamping logic - it requires an external PHY chip. Unlike some other NXP MCUs, it does not embed a physical layer transceiver; the MAC connects via dedicated RMII pins (e.g., ENET_RXD0, ENET_TXD0, ENET_REF_CLK) to external PHYs such as the LAN8720A or KSZ8081RNB.

How many GPIO pins are available on the LPC4330FET180Y in the TFBGA180 package?

The LPC4330FET180Y in the TFBGA180 package provides 118 functional GPIO pins, organized across 16 ports (P0–P9, PA–PF). This count is explicitly confirmed in Table 2 of the LPC4350_30_20_10 datasheet (Rev. 4.6), which lists "118" under the GPIO column for LPC4330FET180. Each pin supports up to eight configurable functions via the System Configuration Unit (SCU).

What is the role of the GIMA (Global Input Multiplexer Array) in the LPC4330FET180Y?

The GIMA in the LPC4330FET180Y enables hardware-level routing of 32+ event sources (e.g., ADC end-of-conversion, timer match, SCT output) to 16+ destinations (e.g., SCT inputs, timer capture, DMA requests) without CPU involvement. This allows deterministic, low-latency peripheral coordination - for example, triggering an ADC conversion upon a PWM edge, then automatically transferring results to SRAM via DMA - all in hardware.

Is the LPC4330FET180Y pin-compatible with other members of the LPC4300 family?

No, the LPC4330FET180Y is not pin-compatible with LBGA256 or LQFP144 variants (e.g., LPC4330FET256 or LPC4330FBD144). Its TFBGA180 package (SOT570-3) has unique ball mapping and signal assignments. Pin compatibility exists only within the same package type - e.g., LPC4330FET180 and LPC4350FET180 share identical TFBGA180 pinouts per NXP's ordering table, differing only in feature enablement (LCD, GPIO count).
