Product details
Overview
LPC11U14FET48/201 from NXP Semiconductors is a 32-bit ARM Cortex-M0 microcontroller designed for USB-connected embedded applications, operating at up to 50 MHz with 32 kB flash, 6 kB SRAM (4 kB main + 2 kB USB), and full-speed USB 2.0 device controller. It integrates a 10-bit ADC (8 channels), two SSP interfaces, one Fast-mode Plus I²C-bus, one RS-485/UART with smart card support, four timers, and 40 GPIO pins - deployed in industrial control, medical devices, and USB audio peripherals.
For engineers reviewing the LPC11U14FET48/201 datasheet, LPC11U14FET48/201 pinout, LPC11U14FET48/201 application, or LPC11U14FET48/201 equivalent, key selection criteria include TFBGA48 package compatibility, USB device stack readiness, 3.3 V single-supply operation (1.8–3.6 V), −40 °C to +85 °C industrial temperature range, and boot ROM-based ISP/IAP programming support.
Technical Context
The LPC11U14FET48/201 implements an ARM Cortex-M0 core with NVIC and NMI support, paired with dual PLL architecture - one for CPU clocking (up to 50 MHz) and a dedicated PLL for USB timing synchronization. Its memory subsystem includes 32 kB flash with sector erase and 6 kB SRAM partitioned into 4 kB general-purpose and 2 kB USB-dedicated RAM for endpoint buffering.
Peripheral integration centers on flexible pin multiplexing via IOCON registers, enabling dynamic assignment of UART, SSP, I²C, timer capture/match, ADC, and USB functions across 40 GPIOs. The device supports four low-power modes (Sleep, Deep-sleep, Power-down, Deep power-down), with wake-up via GPIO, USB activity, watchdog, or dedicated WAKEUP pin (PIO0_16).

The LPC11U14FET48/201 supports 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 validated across the −40 °C to +85 °C temperature range and 1.8–3.6 V supply.
Does the LPC11U14FET48/201 include dedicated memory for USB operations?
Yes, the LPC11U14FET48/201 allocates 2 kB of its 6 kB total SRAM exclusively for USB endpoint buffering. This dedicated USB SRAM ensures deterministic timing for full-speed USB transfers and prevents contention with application code or data stored in the 4 kB main SRAM region.
Which package type does the LPC11U14FET48/201 use, and what are its mechanical dimensions?
The LPC11U14FET48/201 uses the TFBGA48 package (SOT1155-2): a 4.5 mm × 4.5 mm × 0.7 mm plastic thin fine-pitch ball grid array with 48 solder balls. Its compact footprint and low profile make it ideal for ultra-thin USB peripherals and handheld medical devices where board space is constrained.
Can the LPC11U14FET48/201 operate from a single 3.3 V supply across its full temperature range?
Yes, the LPC11U14FET48/201 operates from a single 3.3 V supply (1.8–3.6 V range) across its full industrial temperature range of −40 °C to +85 °C. The internal regulator and ADC reference are both tied to VDD, eliminating need for external voltage references or LDOs in most designs.
How does the LPC11U14FET48/201 support firmware updates in the field?
The LPC11U14FET48/201 supports field firmware updates via its 16 kB boot ROM, which contains certified In-System Programming (ISP) and In-Application Programming (IAP) APIs.
