Product details
Overview
LPC4327JET100E from NXP Semiconductors is a dual-core ARM Cortex-M4F/M0 microcontroller with 1 MB flash, 136 kB SRAM, and integrated USB 2.0 Host/Device interface - designed for industrial control and embedded audio applications requiring deterministic real-time processing and peripheral offload.
For engineers reviewing the LPC4327JET100E datasheet, LPC4327JET100E pinout, LPC4327JET100E application, or LPC4327JET100E equivalent, key selection criteria include its TFBGA100 package, -40 °C to +105 °C temperature grade, absence of Ethernet and LCD controllers, and dedicated USB0-only connectivity without ULPI support.
Technical Context
The LPC4327JET100E integrates an ARM Cortex-M4F core (up to 204 MHz) with hardware FPU and MPU, paired with an ARM Cortex-M0 coprocessor (also up to 204 MHz) for peripheral management and interrupt handling - enabling true asymmetric multiprocessing. Its memory subsystem includes dual-bank flash (512 kB each), 136 kB SRAM distributed across multiple AHB-accessible blocks, and 16 kB EEPROM.
Digital peripherals include two 10-bit ADCs (8 channels total, 400 kSamples/s), one 10-bit DAC, quad-SPI Flash Interface (SPIFI), two SSP controllers, C_CAN 2.0B, I²S, I²C, UART/USART, SCTimer/PWM, GIMA crossbar, and SGPIO - all accessible via AHB/APB buses with DMA support. Power management supports Sleep, Deep-sleep, Power-down, and Deep power-down modes with RTC domain isolation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC4337JET100 | Includes Ethernet MAC (10/100T) and second USB port (USB1 with ULPI option); same flash/SRAM, TFBGA100 package. | Required where IEEE 1588 time-stamped network synchronization or dual-host USB is mandatory. | Select LPC4337JET100 only if Ethernet or secondary USB functionality is needed - adds complexity and BOM cost without benefit for standalone edge nodes. |
| LPC4323JET100 | Reduced memory: 512 kB flash (256+256), 104 kB SRAM; identical peripheral set and TFBGA100 package. | Suitable for cost-optimized implementations with smaller firmware footprints and lower RAM usage. | Choose LPC4323JET100 when application code size stays below 450 kB and runtime heap usage remains under 90 kB - verified via linker map analysis. |
Compared with LPC4337JET100 and LPC4323JET100, the LPC4327JET100E provides optimal balance: full 1 MB flash and 136 kB SRAM for complex firmware and buffering, while omitting unused peripherals (Ethernet, LCD) to reduce EMI susceptibility and simplify layout - ideal for sealed industrial enclosures with USB-centric connectivity.

FAQ
What is the maximum operating frequency of the LPC4327JET100E Cortex-M4F core?
The LPC4327JET100E Cortex-M4F core operates at up to 204 MHz, as specified in the official NXP datasheet Rev. 5.4. This frequency is achievable with proper decoupling, thermal management, and clock configuration using the on-chip PLLs. The LPC4327JET100E maintains this rating across its full -40 °C to +105 °C industrial temperature range.
Does the LPC4327JET100E support Ethernet connectivity?
No, the LPC4327JET100E does not include an Ethernet MAC. According to Table 2 in the NXP LPC435X_3X_2X_1X datasheet Rev. 5.4, Ethernet is explicitly marked "no" for all LPC432x variants including LPC4327JET100E. This omission reduces pin count, power consumption, and PCB routing complexity compared to LPC433x/LPC435x variants.
How many USB interfaces does the LPC4327JET100E provide, and what are their capabilities?
The LPC4327JET100E provides one High-speed USB 2.0 interface (USB0) supporting Host, Device, and OTG roles with integrated PHY. It does not include USB1 or ULPI support. This single-port configuration is sufficient for USB CDC, HID, or mass storage applications but excludes dual-host or high-bandwidth concurrent USB use cases supported by higher-tier LPC43xx variants.
What is the purpose of the Cortex-M0 coprocessor in the LPC4327JET100E?
The Cortex-M0 coprocessor in the LPC4327JET100E handles peripheral management, interrupt servicing, and real-time I/O tasks - freeing the Cortex-M4F core for computationally intensive workloads like digital signal processing or protocol stack execution. Both cores operate independently with shared memory, enabling true asymmetric multiprocessing without software abstraction layers.
Is the LPC4327JET100E pin-compatible with other LPC43xx TFBGA100 variants?
Yes, the LPC4327JET100E shares identical pinout and package (TFBGA100, SOT926-1) with other LPC43xx TFBGA100 variants including LPC4333JET100, LPC4337JET100, and LPC4323JET100. Pin functions are consistent across the family per Table 3 of the datasheet, enabling hardware reuse when migrating between memory/peripheral configurations.
