NXP Semiconductors LPC1827JBD144E

Overview

LPC1827JBD144E from NXP Semiconductors is a 32-bit ARM Cortex-M3 microcontroller operating at up to 180 MHz, featuring 1 MB dual-bank flash, 136 kB SRAM, and 16 kB EEPROM. It integrates a Quad SPI Flash Interface (SPIFI), State-Configurable Timer/PWM (SCTimer/PWM), two High-speed USB interfaces (one with on-chip PHY), and supports industrial control and embedded connectivity applications.

For engineers reviewing the LPC1827JBD144E datasheet, LPC1827JBD144E pinout, LPC1827JBD144E application, or LPC1827JBD144E equivalent, key selection criteria include its LQFP144 package, -40 °C to +105 °C temperature grade, absence of Ethernet and LCD controllers, and presence of motor control PWM and 8-channel ADC support.

Technical Context

The LPC1827JBD144E implements the ARM Cortex-M3 r2p1 core with Harvard architecture, 3-stage pipeline, and integrated Memory Protection Unit (MPU) supporting eight regions. Its clock system includes three PLLs - one for CPU up to 180 MHz, one for USB, and one configurable as audio PLL - plus a 12 MHz internal RC oscillator trimmed to ±3 % accuracy.

Digital peripheral integration centers on the AHB-connected SCTimer/PWM subsystem and Global Input Multiplexer Array (GIMA), enabling flexible event routing between timers, ADCs, and I/O. Analog capability includes two 10-bit ADCs (400 kSamples/s, 8 total channels) and one 10-bit DAC (400 kSamples/s), all with DMA support.

FAQ

What is the maximum operating frequency of the LPC1827JBD144E?

The LPC1827JBD144E operates at a maximum CPU frequency of 180 MHz, achieved using its on-chip PLLs. This frequency is sustained across its full industrial temperature range (-40 °C to +105 °C), with performance validated under worst-case voltage (2.4 V) and temperature conditions per NXP's characterization data.

Does the LPC1827JBD144E include an Ethernet MAC?

No, the LPC1827JBD144E does not include an Ethernet MAC. Per Table 2 in the official datasheet, Ethernet is explicitly marked "no" for this variant. This distinguishes it from LPC183x and LPC185x members, allowing cost and power optimization for applications where wired LAN connectivity is unnecessary.

What peripherals are supported by the SCTimer/PWM subsystem in the LPC1827JBD144E?

The SCTimer/PWM subsystem in the LPC1827JBD144E supports fully programmable state machines with match/capture capabilities, event-triggered actions, and PWM output generation. It interfaces directly with GPIO pins and GIMA for flexible input sourcing, and is used for motor control PWM, LED dimming, and custom waveform synthesis - confirmed in Section 12 of the LPC185X_3X_2X_1X datasheet.

How many ADC channels does the LPC1827JBD144E support, and what is their resolution?

The LPC1827JBD144E supports eight total analog input channels shared between two independent 10-bit ADCs (ADC0 and ADC1), each capable of 400 kSamples/s with DMA support. Channel mapping is fixed per pin (e.g., ADC0_0 and ADC1_0 share the same physical pin), enabling simultaneous sampling for differential or redundant measurements.

Is the LPC1827JBD144E pin-compatible with other LPC18xx LQFP144 variants?

Yes, the LPC1827JBD144E shares identical pinout and package (LQFP144, SOT486-1) with other LPC18xx LQFP144 variants like LPC1833JBD144 and LPC1825JBD144. Pin functions are consistent across the family, though unused peripherals (e.g., Ethernet signals) are reserved or NC - verified in Table 3 of the datasheet's pin description section.
