LPC11U24FHN33/401,

Microcontrollers Overview

The NXP LPC11U24FHN33/401 is a 32-bit microcontroller based on the ARM Cortex-M0 processor, operating at frequencies up to 50 MHz. It features 32 kB of on-chip flash program memory, 8 kB of SRAM data memory, and 4 kB of byte-erasable EEPROM. The device includes a Full-Speed USB 2.0 device controller, one Fast-mode Plus I2C interface, one RS-485/EIA-485 USART with smart card support, two SSP interfaces, four general-purpose counter/timers, and an 8-channel 10-bit ADC. It operates within a voltage range of 1.8 V to 3.6 V and supports temperatures from -40 °C to +85 °C in an HVQFN33 package.

Microcontrollers Feature Summary

• Integrated Full-Speed USB 2.0 device controller with ROM-based drivers for seamless connectivity solutions.
• On-chip EEPROM providing byte-level erasable and programmable non-volatile data storage managed by a dedicated controller.
• Configurable GPIO pins supporting open-drain modes, high-current drivers, and grouped interrupt capabilities.
• Power Management Unit (PMU) enabling multiple reduced power modes including Deep-sleep and Deep power-down.

Microcontrollers Applications

• Consumer peripherals
• Medical devices
• Industrial control systems
• Handheld scanners
• USB audio devices

Microcontrollers Procurement Notes

Verify the specific ordering suffix /401 against the manufacturer's current product status documentation to confirm availability and compliance requirements. Ensure that the HVQFN33 package dimensions match the target PCB footprint specifications. Cross-reference the internal memory configuration (32 kB Flash, 8 kB SRAM, 4 kB EEPROM) with the application design constraints before finalizing procurement orders.

Microcontrollers Selection Notes

Select this component when a low-cost 32-bit MCU with integrated USB functionality is required for space-constrained designs. The HVQFN33 package offers a compact form factor suitable for applications where board real estate is limited. Consider the 8 kB SRAM and 4 kB EEPROM capacities for data logging or parameter storage needs without external memory components.

Microcontrollers Part Context

This part belongs to the NXP LPC11U2x family of microcontrollers designed as replacements for 8/16-bit architectures. The family provides enhanced performance and reduced code size while maintaining compatibility with existing development ecosystems. The LPC11U24 variant specifically targets applications requiring USB connectivity alongside standard peripheral interfaces.
