NXP Semiconductors LPC11E67JBD64E

Overview

LPC11E67JBD64E 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, a 12-bit ADC with 10 input channels, and 50 GPIO pins. It integrates two I²C interfaces (one Fast-mode Plus), five USARTs (four with shared fractional baud generator), two SSP controllers, and a configurable PWM/timer subsystem with SCTimer/PWM capability - deployed in GPS trackers and medical monitors requiring deterministic real-time control and low-power operation.

For engineers reviewing the LPC11E67JBD64E datasheet, LPC11E67JBD64E pinout, LPC11E67JBD64E application, or LPC11E67JBD64E equivalent, key selection criteria include its LQFP64 package with 64 leads, 10-channel 12-bit ADC sampling up to 2 Msamples/s, dual I²C support including Fast-mode Plus, and integrated PMU enabling Deep power-down mode with wake-up via PIO0_16.

Technical Context

The LPC11E67JBD64E implements an ARM Cortex-M0+ core with a two-stage pipeline, single-cycle I/O access, and built-in NVIC for deterministic interrupt handling. Its AHB multilayer matrix enables concurrent peripheral access, while the ROM API provides validated drivers for USART, I²C, DMA, and Flash IAP/ISP operations.

Peripherals are tightly coupled to the core via dedicated trigger muxes: the 12-bit ADC supports two independent conversion sequences with internal/external triggers; the SCTimer/PWM subsystem delivers up to 19 PWM outputs across six independent time bases; and the DMA engine features 16 channels with programmable input triggers tied to GPIO, timer, and ADC events.

FAQ

What is the maximum operating frequency of the LPC11E67JBD64E?

The LPC11E67JBD64E operates at a maximum CPU frequency of 50 MHz using the ARM Cortex-M0+ core. This speed is achievable with the internal PLL enabled and a stable clock source (e.g., 12 MHz IRC or external crystal). The core maintains single-cycle I/O access and deterministic interrupt latency even at full speed, making it suitable for time-critical sensor polling and communication tasks in the LPC11E67JBD64E.

Does the LPC11E67JBD64E include on-chip EEPROM, and what is its endurance?

Yes, the LPC11E67JBD64E integrates 4 KB of on-chip EEPROM with guaranteed endurance of at least 100,000 write/erase cycles and data retention of 10 years at 85 °C. This non-volatile memory is used for storing calibration data, device configuration, or usage logs without requiring external components - a key feature distinguishing the LPC11E67JBD64E from many competing Cortex-M0+ MCUs.

How many ADC input channels does the LPC11E67JBD64E support, and what is its sampling rate?

The LPC11E67JBD64E features a single 12-bit ADC with up to 10 input channels, as confirmed by Table 2 in the datasheet for the LQFP64 variant. It achieves a maximum sample rate of 2 Msamples/s and supports two independent conversion sequences triggered by software, timers, or external events - enabling synchronized multi-sensor acquisition critical in the LPC11E67JBD64E's target applications.

What debug interfaces are supported by the LPC11E67JBD64E?

The LPC11E67JBD64E supports Serial Wire Debug (SWD) as the primary debug interface, with SWDIO and SWCLK assigned to pins 50 and 39 respectively. JTAG boundary scan is also supported via TRST, TDI, TMS, and TDO on pins 46, 42, 43, and 45. SWD is enabled by default at reset; JTAG requires pulling RESET/PIO0_0 LOW during power-up - both protocols are fully functional in the LPC11E67JBD64E.

Is the LPC11E67JBD64E pin-compatible with other members of the LPC11E6x family?

Yes, the LPC11E67JBD64E shares identical pinout and footprint with other LQFP64 variants in the LPC11E6x family, including LPC11E66JBD64, LPC11E68JBD64, and LPC11U68JBD64. All use SOT314-2 packaging with matching signal assignments, power, and ground pin locations - allowing hardware design reuse across memory, peripheral, or USB capability variants without PCB changes in the LPC11E67JBD64E platform.
