Product details
Overview
LPC43S30FET256E from NXP Semiconductors is a dual-core ARM Cortex-M4/M0 flashless microcontroller for industrial and embedded control applications, featuring 264 kB SRAM, hardware AES encryption engine, dual high-speed USB (USB0 Host/Device/OTG + USB1 Host/Device), 10/100T Ethernet MAC with IEEE 1588 support, and 164 GPIO pins in a 256-ball LBGA package.
For engineers reviewing the LPC43S30FET256E datasheet, LPC43S30FET256E pinout, LPC43S30FET256E application, or LPC43S30FET256E equivalent, this page delivers verified core architecture details, validated peripheral configurations, confirmed package mapping to LBGA256, and real-world use-case alignment for secure industrial connectivity and real-time co-processing.
Technical Context
The LPC43S30FET256E integrates an ARM Cortex-M4 core running up to 204 MHz with hardware FPU and MPU, paired with an independent ARM Cortex-M0 coprocessor also operating up to 204 MHz-enabling true asymmetric multiprocessing for offloading real-time tasks like motor control or protocol stacks. Its memory subsystem includes eight SRAM blocks (total 264 kB), two of which support individual power-down, plus 64 kB ROM with boot code and USB stack.
Peripherals are organized across three AHB bridges and a GIMA crossbar, enabling flexible event routing between SCTimer/PWM, ADCs, timers, and GPIO groups. The device supports concurrent high-bandwidth interfaces: Ethernet with RMII/MII, dual USB with on-chip PHYs (USB0 full-speed + HS PHY; USB1 FS PHY + ULPI), SPIFI up to 52 MB/s, and EMC for SDRAM/NOR/SRAM expansion-without shared bus contention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC4350FET256 | Includes LCD controller and second C_CAN channel; 264 kB SRAM same; identical pinout and package. | Required for HMI-integrated designs (e.g., panel meters with TFT display); unnecessary if LCD is unused. | Select LPC4350FET256 only when LCD or dual CAN is mandatory-LPC43S30FET256E saves cost and reduces BOM complexity otherwise. |
| LPC4337FET256 | Same dual-core architecture and peripherals, but lacks AES engine and secure boot ROM; no OTP key storage. | Suitable for non-security-critical applications (e.g., basic industrial I/O); cannot meet FIPS 140-2 or IEC 62443 requirements. | Choose LPC4337FET256 only for cost-sensitive, non-secure deployments where cryptographic acceleration is not required. |
Compared with LPC4350FET256 and LPC4337FET256, the LPC43S30FET256E uniquely balances security (AES + secure boot), industrial connectivity (Ethernet + dual USB), and real-time determinism (dual-core + IEEE 1588)-making it optimal for certified gateways and safety-aware control systems where feature trim must not compromise trust anchors.

FAQ
What is the maximum operating frequency of the LPC43S30FET256E?
The LPC43S30FET256E features two independent processor cores: the ARM Cortex-M4 core runs at up to 204 MHz, and the ARM Cortex-M0 coprocessor also operates at up to 204 MHz. Both cores are fully functional simultaneously, with separate clock domains and debug interfaces. This dual-frequency capability enables high-throughput application processing alongside deterministic real-time task execution in the LPC43S30FET256E.
Does the LPC43S30FET256E include an integrated LCD controller?
No, the LPC43S30FET256E does not include an integrated LCD controller. According to Table 2 in the official NXP datasheet, the LCD function is explicitly marked as "no" for all LPC43S30 variants, including LPC43S30FET256E. This distinguishes it from the LPC43S50FET256, which supports LCD. The LPC43S30FET256E retains all other major peripherals-including Ethernet, dual USB, SCTimer/PWM, and AES-making it optimized for non-HMI industrial control and secure connectivity roles.
What security features are implemented in the LPC43S30FET256E?
The LPC43S30FET256E integrates a hardware AES engine with DMA support for encryption/decryption of boot images and runtime data, 256-bit One-Time Programmable (OTP) memory for secure AES key storage (one bank dedicated to encrypted boot key), a unique device ID, and ROM-based secure boot API. It does not include TrustZone or secure boot certificate validation beyond AES-decrypted image execution. These features collectively enable FIPS-aligned secure boot and data protection in the LPC43S30FET256E.
Which package type is used for the LPC43S30FET256E?
The LPC43S30FET256E uses the LBGA256 package: a plastic low-profile ball grid array with 256 balls, 17 mm × 17 mm × 1 mm body size, and SOT740-2 footprint. This package is pin-compatible with LPC43S50FET256 and supports high-density PCB layouts with robust thermal and electrical performance. The "E" suffix in LPC43S30FET256E denotes industrial temperature grade (–40 °C to +105 °C), confirmed per NXP ordering documentation.
How many USB interfaces does the LPC43S30FET256E support, and what are their capabilities?
The LPC43S30FET256E supports two independent USB interfaces: USB0 is a High-Speed USB 2.0 Host/Device/OTG interface with integrated on-chip high-speed PHY; USB1 is a High-Speed USB 2.0 Host/Device interface with on-chip full-speed PHY and ULPI interface for connection to external high-speed PHYs. Both interfaces include DMA support and ROM-resident USB stack software-enabling simultaneous USB device enumeration and host operation in the LPC43S30FET256E.
