LPC11U14FBD48/201

Microcontrollers Overview

The NXP LPC11U14FBD48/201 is a 32-bit microcontroller based on the ARM Cortex-M0 core, operating at frequencies up to 50 MHz. It features 32 kB of on-chip flash memory and 6 kB of SRAM. The device is housed in a 48-pin LQFP package and includes a full-speed USB 2.0 Device controller. Key peripherals include four general-purpose timers, two SSP interfaces, one I²C-bus interface, and up to eight channels of a 10-bit ADC. It supports in-system programming via an on-chip bootloader.

Microcontrollers Feature Summary

• Integrates a flexible and configurable full-speed USB 2.0 Device controller for seamless connectivity.
• Includes a nested vectored interrupt controller (NVIC) and non-maskable interrupt input for efficient event handling.
• Supports in-system programming (ISP) and in-application programming (IAP) through on-chip bootloader software.

Microcontrollers Applications

• Consumer electronics peripherals
• Handheld scanners
• Medical devices
• Audio equipment
• Industrial control systems

Microcontrollers Procurement Notes

Verify the specific suffix /201 against official NXP documentation to confirm tape-and-reel packaging specifications. Ensure the LQFP-48 footprint matches the target PCB design. Confirm RoHS compliance status with the manufacturer's current datasheet before finalizing procurement orders.

Microcontrollers Selection Notes

Select this component when a low-cost 32-bit MCU with integrated USB functionality is required. It serves as a direct upgrade path for legacy 8-bit or 16-bit applications needing higher performance and reduced code size. Consider the 50 MHz clock speed and available GPIO count for system complexity requirements.

Microcontrollers Part Context

This part belongs to the LPC11Uxx family, designed for cost-sensitive applications requiring USB connectivity. It shares the Cortex-M0 architecture with other LPC11 series variants but distinguishes itself through its specific peripheral set and package configuration. The family targets simple instruction sets with reduced code size for efficient embedded operations.

Microcontrollers Replacement Considerations

Check for pin-compatible alternatives within the LPC11Uxx series that offer different memory sizes or package types. Verify if newer revisions of the LPC11U14 exist with updated manufacturing processes. Ensure any substitute maintains the same USB controller capabilities and voltage range specifications.
