Product details
Overview
LPC1113FHN33/203 from NXP Semiconductors is an ARM Cortex-M0-based 32-bit microcontroller in a 33-terminal HVQFN package, operating at up to 50 MHz with 24 kB flash, 4 kB SRAM, and integrated UART (RS-485), Fast-mode Plus I²C, two SPI interfaces, four timers, and an 8-channel 10-bit ADC. It targets low-power industrial control and sensor interface applications requiring compact footprint and robust peripheral integration.
For engineers reviewing the LPC1113FHN33/203 datasheet, LPC1113FHN33/203 pinout, LPC1113FHN33/203 application, or LPC1113FHN33/203 equivalent, this page delivers verified specifications, package mapping, functional alternatives, and design-critical context for embedded system integration, power-constrained firmware development, and industrial-grade signal acquisition.
Technical Context
The LPC1113FHN33/203 belongs to the LPC1100XL series, enabling In-Application Programming (IAP) with page-erase capability and enhanced timer capture functionality-including capture-clear on 16-bit and 32-bit timers for precise pulse-width measurement. Its clock system integrates a 12 MHz ±1% internal RC oscillator, crystal oscillator (1–25 MHz), PLL, and programmable watchdog oscillator (7.8 kHz–1.8 MHz).
Power management includes Sleep, Deep-sleep, and Deep power-down modes managed by an integrated PMU, with wake-up support via up to 13 GPIO pins. The device supports power profiles for optimized active/sleep trade-offs and features brownout detection with four configurable thresholds for reset or interrupt generation.

FAQ
What is the maximum operating frequency of the LPC1113FHN33/203?
The LPC1113FHN33/203 operates at a maximum CPU frequency of 50 MHz, achievable via its integrated PLL driven by either the internal 12 MHz RC oscillator or an external crystal (1–25 MHz). This frequency is fully supported across the −40 °C to +85 °C industrial temperature range with appropriate voltage supply (1.8–3.6 V).
Does the LPC1113FHN33/203 support In-Application Programming (IAP)?
Yes, the LPC1113FHN33/203 supports In-Application Programming (IAP) with page-erase capability as part of the LPC1100XL series feature set. This allows firmware updates to be performed while the device is running, using the on-chip bootloader without requiring external programming hardware or full chip erase.
How many ADC channels does the LPC1113FHN33/203 provide, and what is their resolution?
The LPC1113FHN33/203 integrates a 10-bit successive-approximation ADC with eight selectable input channels (ADC_IN0–ADC_IN7), mapped to specific GPIO pins. Resolution is fixed at 10 bits, providing 1024 discrete levels across the VDD reference range, suitable for precision analog sensing in industrial monitoring applications.
What power-saving modes are available on the LPC1113FHN33/203?
The LPC1113FHN33/203 implements three reduced-power modes: Sleep (CPU halted, peripherals active), Deep-sleep (CPU and most clocks stopped, SRAM retained), and Deep power-down (all clocks off, SRAM lost, wake-up only via dedicated pins or RTC). Power profiles in boot ROM simplify configuration of optimal active/sleep trade-offs.
Is the LPC1113FHN33/203 pin-compatible with other LPC111x HVQFN33 variants?
Yes, the LPC1113FHN33/203 shares identical pinout and package dimensions (HVQFN33, 7×7 mm) with other LPC111x HVQFN33 variants such as LPC1111FHN33/203, LPC1112FHN33/203, and LPC1114FHN33/203. Pin functions, power, and ground locations are consistent across this package family, enabling drop-in replacement within the same series.
