Product details
Overview
LPC43S30FBD144E from NXP Semiconductors is a dual-core ARM Cortex-M4/M0 flashless microcontroller for secure embedded control, operating at up to 204 MHz with 264 kB SRAM, integrated AES encryption engine, 10/100T Ethernet MAC, and dual high-speed USB interfaces (USB0 Host/Device/OTG + USB1 Host/Device). It targets industrial gateways requiring real-time co-processing and secure boot.
For engineers reviewing the LPC43S30FBD144E datasheet, LPC43S30FBD144E pinout, LPC43S30FBD144E application, or LPC43S30FBD144E equivalent, key selection considerations include its LQFP144 package with 83 GPIOs, absence of LCD controller (vs. LPC43S50), USB1 ULPI-only interface, and support for IEEE 1588 time stamping in Ethernet applications.
Technical Context
The LPC43S30FBD144E integrates an ARM Cortex-M4 core with hardware FPU and MPU alongside a fully independent ARM Cortex-M0 coprocessor-both running up to 204 MHz-enabling true parallel execution of real-time control (M0) and application processing (M4). Its memory subsystem includes 264 kB SRAM distributed across multiple AHB-accessible blocks, plus 64 kB ROM with boot code and cryptographic APIs.
Peripherals are routed via a multi-layer AHB matrix with GIMA crossbar, supporting concurrent access to Ethernet MAC, dual USB controllers, SCTimer/PWM, SGPIO, and dual 10-bit ADCs (8 channels each). The device implements dedicated security features including OTP memory banks for encrypted AES keys and ROM-based API for DMA-accelerated boot image decryption.

What is the maximum operating frequency of the LPC43S30FBD144E?
The LPC43S30FBD144E supports CPU operation at up to 204 MHz for both the ARM Cortex-M4 and Cortex-M0 cores. This frequency is achieved using the internal PLLs driven by the 12 MHz IRC oscillator or an external crystal (1–25 MHz), with voltage regulation maintained across the 2.2–3.6 V supply range.
Does the LPC43S30FBD144E include an integrated LCD controller?
No, the LPC43S30FBD144E does not include an LCD controller. According to Table 2 in the datasheet, LCD functionality is excluded from all LPC43S30 variants-including LPC43S30FBD144E-distinguishing it from the LPC43S50 family which retains this feature in equivalent packages.
How many USB interfaces does the LPC43S30FBD144E support, and what are their capabilities?
The LPC43S30FBD144E supports two USB interfaces: USB0 is a High-Speed (480 Mbps) Host/Device/OTG interface with integrated on-chip PHY; USB1 is a High-Speed Host/Device interface with ULPI interface only-requiring an external PHY for HS operation and lacking OTG capability.
What security features are implemented in the LPC43S30FBD144E?
The LPC43S30FBD144E includes a hardware AES-128/256 engine with DMA support, two 256-bit OTP memory banks (one for encrypted boot key storage), 64-bit general-purpose OTP, and ROM-resident cryptographic APIs-all enabling secure boot, firmware authentication, and runtime data encryption without CPU overhead.
Is IEEE 1588 time stamping supported on the Ethernet interface of the LPC43S30FBD144E?
Yes, the LPC43S30FBD144E's 10/100T Ethernet MAC supports IEEE 1588-2008 v2 (PTP) with hardware timestamping logic for transmit and receive frames-enabling sub-microsecond synchronization accuracy required in time-sensitive networking and industrial automation applications.
