NXP Semiconductors LPC11E67JBD100E

Overview

LPC11E67JBD100E from NXP Semiconductors is a 32-bit ARM Cortex-M0+ microcontroller operating at up to 50 MHz, featuring 128 KB flash, 4 KB EEPROM, 20 KB SRAM, one 12-bit ADC with 12 input channels, and up to 80 GPIO pins. It targets embedded control in resource-constrained industrial and consumer systems requiring integrated analog sensing, multi-protocol serial connectivity, and low-power operation.

For engineers reviewing the LPC11E67JBD100E datasheet, LPC11E67JBD100E pinout, LPC11E67JBD100E application, or LPC11E67JBD100E equivalent, key selection criteria include its LQFP100 package with full USART4 support, 12-channel ADC capability, dual I²C interfaces (one Fast-mode Plus), and deep power-down wake-up via PIO0_16 - critical for battery-powered telemetry and metering designs.

Technical Context

The LPC11E67JBD100E implements an ARM Cortex-M0+ core with a two-stage pipeline, single-cycle I/O access, and integrated NVIC for deterministic interrupt handling. Its AHB multilayer matrix enables concurrent peripheral access without bus contention, while the Micro Trace Buffer (MTB) supports real-time instruction trace in debug sessions.

Peripheral architecture includes a configurable PWM/timer subsystem (SCTimer/PWM + standard timers), hardware CRC engine, DMA controller with 16 channels, and clock generation with PLL, IRC, and dedicated RTC oscillator. The device supports five USARTs (including RS-485 mode), two SSP controllers, and two I²C-bus interfaces - one with Fast-mode Plus open-drain drivers on dedicated pins.

FAQ

What is the maximum operating frequency of the LPC11E67JBD100E?

The LPC11E67JBD100E operates at a maximum CPU frequency of 50 MHz using its internal PLL, enabling real-time processing of sensor data, communication protocols, and control algorithms without external high-frequency crystals. This frequency is fully supported across the specified −40 °C to +105 °C temperature range and 2.4 V–3.6 V supply voltage.

Does the LPC11E67JBD100E include on-chip EEPROM, and what is its capacity?

Yes, the LPC11E67JBD100E integrates 4 KB of on-chip EEPROM, accessible via dedicated EEPROM controller and supporting byte/word read/write operations. This memory retains calibration data, device configuration, and usage logs across power cycles - eliminating the need for external non-volatile storage in applications like smart meters and portable medical devices.

How many USART interfaces does the LPC11E67JBD100E support, and which ones are available on the LQFP100 package?

The LPC11E67JBD100E supports five USART interfaces (USART0 through USART4), and all five are physically available on the LQFP100 package. USART4 pins (U4_TXD, U4_RXD, U4_CTS, U4_RTS, U4_SCLK) are assigned to PIO2_10 through PIO2_14 - a key differentiator versus LQFP48/LQFP64 variants, enabling true five-port serial gateway functionality.

What ADC resolution and channel count does the LPC11E67JBD100E provide?

The LPC11E67JBD100E features a single 12-bit successive-approximation ADC with up to 12 input channels (ADC_0 through ADC_11), supporting sample rates up to 2 Msamples/s. It includes two independent conversion sequences and multiple trigger sources (timer, software, external event), allowing synchronized multi-channel acquisition for applications such as three-phase power monitoring and biomedical signal conditioning.

Is the LPC11E67JBD100E compatible with SWD debugging, and what pins are required?

Yes, the LPC11E67JBD100E supports Serial Wire Debug (SWD) using SWDIO (PIO0_15, pin 81) and SWCLK (PIO0_10, pin 60), both located on the LQFP100 package. These pins are enabled by default at reset and require no configuration to enter debug mode - enabling seamless firmware development and field diagnostics with standard ARM-compliant debug probes.
