NXP Semiconductors LPC1815JET100E

Overview

LPC1815JET100E from NXP Semiconductors is a 32-bit ARM Cortex-M3 microcontroller targeting industrial and embedded control applications. It operates at up to 180 MHz, integrates 768 kB flash (384 kB per bank), 136 kB SRAM, and supports TFBGA100 packaging. Key peripherals include dual 10-bit ADCs (400 kSamples/s), 10/100T Ethernet MAC with IEEE 1588 support, and two High-speed USB interfaces - one with on-chip PHY (USB0), one with ULPI interface (USB1).

For engineers reviewing the LPC1815JET100E datasheet, LPC1815JET100E pinout, LPC1815JET100E application, or LPC1815JET100E equivalent, this page delivers verified technical context, package-specific pin functions, real-world use cases, and validated alternative options for industrial control, e-metering, and white goods designs.

Technical Context

The LPC1815JET100E implements an ARM Cortex-M3 r2p1 core with Harvard architecture, 3-stage pipeline, and integrated Memory Protection Unit (MPU) supporting eight memory regions. Its clock system includes three PLLs: one for CPU operation up to 180 MHz, one dedicated to USB0, and one configurable as audio PLL.

Digital subsystems feature a State-Configurable Timer/PWM (SCTimer/PWM) with flexible event routing via GIMA, an External Memory Controller (EMC) supporting SDRAM/NOR flash, and a Global Input Multiplexer Array enabling cross-peripheral signal chaining. No LCD or motor control PWM is included in this variant, per ordering table confirmation.

FAQ

What is the maximum operating frequency of the LPC1815JET100E?

The LPC1815JET100E operates at a maximum CPU frequency of 180 MHz, achieved using its internal PLL with a crystal oscillator input (1–25 MHz range). This frequency is sustained across the full –40 °C to +105 °C industrial temperature range, with voltage regulation maintained by the on-chip core regulator. The LPC1815JET100E's performance is validated under worst-case thermal and voltage conditions per NXP's characterization data.

Does the LPC1815JET100E include an Ethernet MAC?

No, the LPC1815JET100E does not include an Ethernet MAC. Per Table 2 in the official datasheet, Ethernet is explicitly marked "no" for all LPC181x variants including LPC1815JET100E. This distinguishes it from LPC183x/LPC185x families. The LPC1815JET100E retains USB0/USB1, dual ADCs, and EMC but omits Ethernet and LCD controllers to reduce cost and die size.

How much SRAM and flash memory does the LPC1815JET100E have?

The LPC1815JET100E integrates 136 kB of on-chip SRAM and 768 kB of flash memory, organized as two 384 kB banks. This configuration supports secure firmware updates with rollback capability and real-time data buffering for communication stacks. The SRAM is partitioned into multiple AHB-accessible blocks, enabling concurrent DMA transfers without CPU contention - a key design advantage in high-throughput industrial protocols.

What is the package type and pin count of the LPC1815JET100E?

The LPC1815JET100E uses a TFBGA100 package (SOT926-1): a 100-ball, 9 mm × 9 mm × 0.7 mm thin fine-pitch ball grid array. This package is optimized for compact industrial modules and metering applications where board space and thermal dissipation are constrained. Pin assignments are documented in Section 6.2 of the datasheet, with multiplexed functions per pin defined for GPIO, USB, ADC, and EMC interfaces.

Which USB interfaces are supported on the LPC1815JET100E?

The LPC1815JET100E supports two USB 2.0 interfaces: USB0 (Host/Device/OTG) with integrated high-speed PHY, and USB1 (Host/Device) with ULPI interface for external PHY connection. USB0 enables direct USB device enumeration or host-mode peripheral attachment, while USB1's ULPI support allows flexible PHY selection - critical for EMI-sensitive industrial environments where external PHY placement aids noise mitigation. Both interfaces include DMA support to offload CPU bandwidth.
