NXP Semiconductors LPC4337JET100E

Overview

LPC4337JET100E from NXP Semiconductors is a dual-core ARM Cortex-M4F/M0 microcontroller with 1 MB flash, 136 kB SRAM, and integrated Ethernet MAC, dual high-speed USB (one with on-chip PHY), and 10-bit ADC/DAC - deployed in industrial gateways requiring deterministic real-time control and networked I/O.

For engineers reviewing the LPC4337JET100E datasheet, LPC4337JET100E pinout, LPC4337JET100E application, or LPC4337JET100E equivalent, key selection criteria include TFBGA100 package footprint, -40°C to +105°C industrial temperature grade, absence of LCD controller and QEI, and USB1 limited to full-speed PHY only (no ULPI).

Technical Context

The LPC4337JET100E implements a tightly coupled dual-core architecture: the Cortex-M4F core runs at up to 204 MHz with hardware FPU and MPU, while the Cortex-M0 coprocessor operates concurrently at up to 204 MHz for peripheral offload and deterministic interrupt handling. Both cores share access to AHB multilayer matrix and multiple SRAM banks.

Its peripheral set includes a 10/100T Ethernet MAC with IEEE 1588 v2 timestamping, two high-speed USB controllers (USB0 with on-chip HS PHY; USB1 with on-chip FS PHY only), quad SPI Flash Interface (SPIFI) supporting execute-in-place, and dual 10-bit ADCs (400 kSamples/s, 4 channels total) - all accessible via GIMA crossbar routing and configurable through SCU registers.

FAQ

What is the maximum operating frequency of the LPC4337JET100E?

The LPC4337JET100E supports CPU operation up to 204 MHz on both the ARM Cortex-M4F and Cortex-M0 cores. This frequency is achieved using internal PLLs fed from the 12 MHz IRC or an external crystal (1–25 MHz), with voltage and temperature derating applied per the datasheet's electrical characteristics table. The LPC4337JET100E maintains this speed across its full -40°C to +105°C industrial temperature range when supplied with 3.3 V ±10%.

Does the LPC4337JET100E include an LCD controller?

No, the LPC4337JET100E does not include an LCD controller. According to Table 2 in the official NXP datasheet (Rev. 5.4), LCD support is explicitly marked "no" for all LPC433x variants including LPC4337JET100E. This distinguishes it from LPC435x parts like LPC4357JET256, which do integrate an LCD controller supporting up to 1024×768 resolution.

How many USB interfaces does the LPC4337JET100E support, and what are their capabilities?

The LPC4337JET100E supports two USB interfaces: USB0 is a high-speed (480 Mbps) Host/Device/OTG controller with an integrated on-chip high-speed PHY; USB1 is a full-speed (12 Mbps) Host/Device controller with an integrated full-speed PHY only - it lacks ULPI interface support, precluding connection to external high-speed PHYs. This configuration is confirmed in Table 2 of the NXP datasheet for LPC4337JET100E.

What is the GPIO count and peripheral mapping capability of the LPC4337JET100E?

The LPC4337JET100E provides 49 GPIO pins, each configurable via the System Configuration Unit (SCU) to support up to eight alternate functions including UART, I²C, SSP, I²S, USB, Ethernet, and ADC inputs. Pin multiplexing is documented in Table 3 of the datasheet, and the Global Input Multiplexer Array (GIMA) allows dynamic routing of timer, SCT, and ADC events to any GPIO - enabling flexible signal routing without hardware changes.

Is the LPC4337JET100E pin-compatible with other LPC43xx variants in the TFBGA100 package?

Yes, the LPC4337JET100E shares identical pinout and ball assignment with all other LPC43xx devices offered in the TFBGA100 package (e.g., LPC4333JET100, LPC4327JET100, LPC4317JET100), as verified in Figure 3 ("Pin configuration TFBGA100 package") and Table 3 ("Pin description") of the NXP datasheet. This enables direct substitution within the same family when flash size, SRAM, or peripheral requirements align.
