Product details
Overview
LPC11U24FET48/301 from NXP Semiconductors is a 32-bit ARM Cortex-M0 microcontroller operating at up to 50 MHz, featuring 32 kB flash, 6 kB main SRAM, 2 kB EEPROM, and a full-speed USB 2.0 device controller. It integrates a 10-bit ADC with 8 input channels, two SSP interfaces, one Fast-mode Plus I²C-bus, and a USART supporting RS-485 and smart card modes - deployed in compact TFBGA48 packaging for space-constrained USB-connected peripherals.
For engineers reviewing the LPC11U24FET48/301 datasheet, LPC11U24FET48/301 pinout, LPC11U24FET48/301 application, or LPC11U24FET48/301 equivalent, key selection criteria include USB device stack support in ROM, 40 GPIO pins with configurable pull-up/pull-down and interrupt capability, low-power Deep power-down mode with dedicated WAKEUP pin, and compatibility with NXP's LPCXpresso development ecosystem.
Technical Context
The LPC11U24FET48/301 implements an ARM Cortex-M0 core with NVIC and NMI support, paired with dual PLLs - one for CPU clocking (up to 50 MHz) and a dedicated USB PLL for precise 48 MHz timing. Its memory subsystem includes boot ROM with USB drivers and integer division routines, enabling firmware updates over USB without external host software.
Peripheral control is centralized via IOCON registers per GPIO pin, supporting open-drain, repeater, and hysteresis configuration. The USB interface operates in full-speed mode only, with hardware SoftConnect via USB_CONNECT pin and VBUS sensing on PIO0_3 - all compliant with USB 2.0 specification and validated for embedded device-class applications.
Key Specifications

Pinout & Package
Package: TFBGA48 (plastic thin fine-pitch ball grid array; 48 balls; body 4.5 × 4.5 × 0.7 mm; SOT1155-2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RESET/PIO0_0 | Reset input / GPIO | External reset with 20 ns glitch filter; also serves as debug select (JTAG vs SWD); must be pulled HIGH externally in Deep power-down mode. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC11U24FBD48/301 | LQFP48 package (7 × 7 × 1.4 mm); identical electrical specs and pinout mapping except for ball-to-lead conversion. | Better suited for prototyping and manual soldering; lacks TFBGA48's board area efficiency. | Select when PCB assembly uses reflow-only processes or requires easier debug probe access. |
| LPC11U37FBD64/401 | LQFP64 package; adds 2 kB USB RAM, 2 kB additional SRAM, and 14 extra GPIO (54 total); same core and peripheral set. | Required for designs needing >40 GPIO or larger USB endpoint buffers (e.g., composite USB devices). | Choose when scaling beyond 40 I/O or requiring dual USB endpoints with independent buffer allocation. |
Compared with LPC11U24FBD48/301, the TFBGA48 variant saves 30% PCB area but requires precision placement; versus LPC11U37FBD64/401, it trades I/O count and USB RAM for compactness and lower component height - critical for ultra-thin enclosures.

FAQ
What is the maximum operating frequency of the LPC11U24FET48/301?
The LPC11U24FET48/301 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 PLL. This frequency is fully supported across its specified temperature range (−40 °C to +85 °C) and supply voltage (1.8 V to 3.6 V).
Does the LPC11U24FET48/301 support USB host functionality?
No, the LPC11U24FET48/301 only implements a USB 2.0 full-speed device controller - it cannot act as a USB host. Its USB interface is strictly device-side, supporting standard classes like CDC ACM and HID via ROM-resident drivers. Host capability requires external USB OTG ICs or higher-tier MCUs such as NXP's LPC17xx or LPC18xx families.
How many ADC input channels does the LPC11U24FET48/301 provide?
The LPC11U24FET48/301 features a 10-bit ADC with eight single-ended input channels (AD0 through AD7), mapped to specific GPIO pins including PIO0_11, PIO0_12, PIO0_13, PIO0_14, PIO0_15, PIO0_16, PIO0_22, and PIO0_23. All channels share a common VDD reference and support programmable sampling rates up to 1 MS/s.
Can the LPC11U24FET48/301 enter Deep power-down mode and retain memory contents?
Yes, the LPC11U24FET48/301 supports Deep power-down mode with sub-1 µA current draw. In this state, the 2 kB EEPROM and 16 bytes of designated SRAM retain data, while the rest of SRAM loses content. Wake-up is triggered exclusively by a LOW pulse on the dedicated WAKEUP pin (PIO0_16), with 50 ns minimum pulse width detection.
Is the LPC11U24FET48/301 pin-compatible with other LPC11U2x variants in TFBGA48 packaging?
Yes, the LPC11U24FET48/301 shares identical pinout and ball assignment with other TFBGA48 variants in the LPC11U2x family, including LPC11U24FHI33/301 (HVQFN33) and LPC11U24FET48/301 itself - though functional differences exist in memory size and peripheral enablement. Pin-for-pin compatibility is confirmed in Table 3 of the official datasheet Rev. 2.3.
