LPC804M111JDH24FP

Microcontrollers Overview

The LPC804M111JDH24FP is a 32-bit microcontroller based on the Arm Cortex-M0+ core, operating at frequencies up to 15 MHz. It features 32 KB of flash memory and 4 KB of SRAM. The device includes a 12-bit ADC, 10-bit DAC, analog comparator, capacitive touch interface, and Programmable Logic Unit (PLU). It supports dual I/O power supplies for level shifting between voltage domains. Communication interfaces include two I2C-bus interfaces, two USARTs, and one SPI controller.

Microcontrollers Feature Summary

• Dual I/O power supply capability enabling independent voltage domains for level-shifting signals
• Switch matrix functionality providing flexible configuration of I/O pin functions
• Programmable Logic Unit (PLU) for creating small combinatorial or sequential logic networks
• Capacitive Touch Interface integrated for touch sensing applications

Microcontrollers Applications

• Sensor gateways
• Simple motor control
• Industrial automation
• Portables and wearables
• Fire and security applications

Microcontrollers Procurement Notes

Verify the complete part number LPC804M111JDH24FP against official NXP documentation to ensure correct package type and feature set. Confirm that the dual I/O power supply requirement matches the specific application design. Check for any specific boot code version or device revision identifiers if required by the system firmware. Ensure compatibility with existing development tools and debug probes.

Microcontrollers Selection Notes

Select this component when dual voltage domain interfacing is necessary within a single MCU package. The LPC804M111JDH24FP is suitable for designs requiring level shifting without external translators. Consider the PLU and Capacitive Touch features for simplified peripheral management. Evaluate the 15 MHz operating frequency against processing requirements. Verify that the TSSOP24 package fits the PCB layout constraints.

Microcontrollers Part Context

This part belongs to the LPC800 series of low-cost microcontrollers based on the Arm Cortex-M0+ core. The series targets upgrades from traditional 8-bit and 16-bit MCUs. The LPC804 variant specifically offers 32 KB of flash and 4 KB of SRAM. It is designed for applications requiring low pin count and efficient peripheral integration.

Microcontrollers Replacement Considerations

LPC804M101JDH24 is a similar TSSOP24 package option but lacks the dual I/O power supply feature.
