LPC1112FHN33/103,5

Microcontrollers Overview

The NXP LPC1112FHN33/103,5 is a 32-bit microcontroller based on the ARM Cortex-M0 core. It features 16 kB of on-chip flash memory and 2 kB of SRAM. The device operates at CPU frequencies up to 50 MHz and supports a single power supply ranging from 1.8 V to 3.6 V. It includes one UART, one I2C interface with Fast-mode Plus support, two SPI controllers, four general-purpose timers, and an 8-channel 10-bit ADC. The component is housed in an HVQFN-33 package and supports extended temperature operation.

Microcontrollers Feature Summary

Supports In-System Programming (ISP) and In-Application Programming (IAP) via on-chip bootloader software.
Includes a programmable windowed watchdog timer for system reliability.
Features integrated power management unit to minimize consumption during Sleep, Deep-sleep, and Deep power-down modes.
Provides configurable open-drain mode for GPIO pins.

Microcontrollers Procurement Notes

Verify the specific ordering suffix matches the required package variant and temperature range. Confirm that the /103 designation corresponds to the LPC1100XL series specifications, including the windowed watchdog timer and power profiles. Ensure compatibility with moisture sensitivity levels and storage conditions as defined by the manufacturer's labeling standards.

Microcontrollers Selection Notes

Select this part when a low-cost 32-bit MCU with the LPC1100XL feature set is required. It is suitable for applications needing 16 kB of flash and 2 kB of RAM within an HVQFN-33 footprint. Consider the extended temperature range if operating environments exceed standard industrial limits.

Microcontrollers Part Context

This component belongs to the NXP LPC11xx family of ARM Cortex-M0 microcontrollers. Specifically, it is part of the LPC1100XL series, which adds power profiles and a windowed watchdog timer compared to the base LPC1100 series. The family is designed to replace 8/16-bit architectures while offering higher performance and lower power consumption.
