NXP Semiconductors LPC43S37JET100E

Overview

LPC43S37JET100E from NXP Semiconductors is a dual-core ARM Cortex-M4F/M0 microcontroller for industrial and embedded control applications, featuring 1 MB flash (512 kB per bank), 136 kB SRAM, integrated AES encryption engine, dual USB 2.0 interfaces (one with on-chip HS PHY, one with ULPI), and 10/100T Ethernet MAC with IEEE 1588 support - deployed in motor control, e-metering, and RFID reader systems.

For engineers reviewing the LPC43S37JET100E datasheet, LPC43S37JET100E pinout, LPC43S37JET100E application, or LPC43S37JET100E equivalent, key selection considerations include its TFBGA100 package with 49 GPIOs, absence of LCD controller and QEI, single USB1 without on-chip HS PHY, and 4-channel ADC configuration - critical for footprint-constrained, security-aware, real-time industrial designs.

Technical Context

The LPC43S37JET100E integrates an ARM Cortex-M4F core (up to 204 MHz) with hardware FPU and MPU, paired with a fully independent Cortex-M0 coprocessor (also up to 204 MHz) for offloading real-time tasks. Its memory subsystem includes dual-bank flash with accelerator, 16 kB EEPROM, and segmented SRAM blocks - two of which support individual power-down.

Peripherals are routed via AHB multilayer matrix and GIMA crossbar, enabling flexible event-driven routing between timers (SCT, general-purpose), ADCs, and communication interfaces. The device supports secure boot via AES-128 engine with OTP key storage and ROM-based API, and features three PLLs - one dedicated to USB, one to audio, and one for CPU clock generation.

FAQ

What is the maximum operating frequency of the LPC43S37JET100E?

The LPC43S37JET100E operates at a maximum CPU frequency of 204 MHz for both the ARM Cortex-M4F and Cortex-M0 cores. This frequency is achieved using the on-chip PLLs fed by the internal 12 MHz RC oscillator or an external crystal (1–25 MHz). The M4F core includes a hardware floating-point unit and memory protection unit, while the M0 core maintains full code and tool compatibility with the M4F - enabling efficient asymmetric processing in real-time applications.

Does the LPC43S37JET100E include an LCD controller?

No, the LPC43S37JET100E does not include an LCD controller. According to Table 2 in the NXP LPC43S5x/S3x datasheet Rev. 1.3, the LCD feature is explicitly marked "no" for the LPC43S37JET100 variant. This omission distinguishes it from higher-pin-count variants like LPC43S57JET256 and LPC43S57JBD208, which support programmable display resolutions up to 1024×768. The LPC43S37JET100E retains all other major peripherals including Ethernet, dual USB, AES, and dual ADCs - optimized for compact, non-display industrial applications.

How many ADC channels does the LPC43S37JET100E support?

The LPC43S37JET100E supports four total ADC input channels - two 10-bit ADCs (ADC0 and ADC1), each with four dedicated input channels. As confirmed in Table 2 and Section 2.2 ("Analog peripherals") of the datasheet, this is half the eight-channel capability found in LPC43S5x variants. Each ADC achieves 400 kSamples/s with DMA support, and channel inputs are multiplexed across shared pins - allowing simultaneous sampling for current/voltage sensing in motor control or energy measurement applications.

What USB PHY configurations are supported on the LPC43S37JET100E?

The LPC43S37JET100E supports two USB 2.0 interfaces with distinct PHY implementations: USB0 integrates an on-chip high-speed PHY, enabling direct connection to USB connectors without external components; USB1 provides only a ULPI interface, requiring an external high-speed PHY chip (e.g., SMSC USB3343) for full-speed or high-speed operation. This configuration balances integration and flexibility - USB0 delivers plug-and-play functionality, while USB1 allows PHY selection based on EMI, cost, or legacy compatibility requirements in the final design.

Is the LPC43S37JET100E qualified for extended temperature operation?

Yes, the LPC43S37JET100E is rated for operation from −40 °C to +105 °C, as indicated by the "J" suffix in its part number per Table 1 of the NXP datasheet. This industrial temperature grade is validated across all specified electrical parameters, including flash programming, SRAM retention, USB signaling integrity, and Ethernet MAC timing - making it suitable for deployment in harsh environments such as outdoor metering enclosures, factory-floor controllers, and transportation infrastructure equipment.
