Product details
Overview
LPC11U14FBD48/201 from NXP Semiconductors is a 32-bit ARM Cortex-M0 microcontroller in LQFP48 package, operating at up to 50 MHz with 32 kB flash, 6 kB SRAM (4 kB main + 2 kB USB), and integrated Full-Speed USB 2.0 device controller. It delivers low-power embedded control for USB-connected peripherals requiring deterministic real-time response, such as handheld scanners and medical sensors.
For engineers reviewing the LPC11U14FBD48/201 datasheet, LPC11U14FBD48/201 pinout, LPC11U14FBD48/201 application, or LPC11U14FBD48/201 equivalent, key selection criteria include USB device stack readiness, 10-bit ADC with 8-channel multiplexing, dual SSP interfaces for SPI/SSI/Microwire, I²C Fast-mode Plus support up to 1 Mbit/s, and wake-up capability from Deep power-down mode via dedicated WAKEUP pin.
Technical Context
The LPC11U14FBD48/201 implements a single-core ARM Cortex-M0 processor with NVIC and NMI support, paired with two independent PLLs-one for CPU clock generation (up to 50 MHz) and a second dedicated PLL for USB timing compliance. Its memory subsystem includes boot ROM with ISP/IAP firmware, 32 kB flash with sector erase, and segregated SRAM banks optimized for USB packet buffering and general-purpose execution.
Digital peripheral routing is managed through programmable IOCON registers per pin, enabling dynamic function assignment (e.g., CT32B0_MAT1 on PIO0_19 or PIO1_25) and configurable drive modes-including high-current sink (20 mA) on true open-drain pins PIO0_4/PIO0_5 and high-current source (20 mA) on PIO0_7. The 10-bit ADC supports simultaneous sampling across eight analog inputs with internal reference derived from VDD.

FAQ
What is the maximum operating frequency of the LPC11U14FBD48/201?
The LPC11U14FBD48/201 operates at a maximum CPU frequency of 50 MHz, achieved using either the internal 12 MHz IRC oscillator with PLL multiplication or an external crystal (1–25 MHz) fed into the system oscillator and PLL. This frequency is fully supported across the entire industrial temperature range (−40 °C to +85 °C) and specified in the official NXP datasheet Rev. 2.2.
Does the LPC11U14FBD48/201 support USB device functionality without external components?
Yes, the LPC11U14FBD48/201 integrates a full-speed USB 2.0 device controller with SoftConnect capability. The USB_CONNECT pin (PIO0_6) allows software-controlled activation of the internal 1.5 kΩ pull-up resistor on D+, eliminating the need for external discrete components during USB enumeration. USB_DP and USB_DM are routed directly to the USB connector with no transceiver required.
How many analog input channels does the LPC11U14FBD48/201 ADC support?
The LPC11U14FBD48/201 features a 10-bit successive approximation ADC with multiplexing across eight analog input pins: AD0 through AD7. These correspond to physical pins PIO0_11, PIO0_12, PIO0_13, PIO0_14, PIO0_15, PIO0_16, PIO0_22, and PIO0_23 - all accessible simultaneously in sequence scan mode with programmable sample time.

Yes, the LPC11U14FBD48/201 in LQFP48 package is pin-compatible with LPC11U12FBD48/201 and LPC11U13FBD48/201, sharing identical pin functions, electrical characteristics, and package dimensions. This enables direct substitution in existing designs when upgrading flash capacity or maintaining footprint consistency across product variants.
What power-saving modes are available on the LPC11U14FBD48/201?
The LPC11U14FBD48/201 supports four reduced-power modes: Sleep (CPU halted, peripherals active), Deep-sleep (CPU and most clocks stopped), Power-down (all clocks stopped except wake-up sources), and Deep power-down (only WAKEUP pin and reset functional, <1 µA typical current). Wake-up is supported via GPIO, USB activity, watchdog, or the dedicated WAKEUP pin (PIO0_16).
