Overview

LPC1113FHN33/201 from NXP Semiconductors is a 32-bit ARM Cortex-M0 microcontroller in HVQFN33 package, operating up to 50 MHz with 24 kB flash, 4 kB SRAM, one UART (RS-485 capable), one I²C-bus interface, one SPI, four timers, and a 10-bit ADC with 8-channel input multiplexing - used in smart lighting control and embedded metering systems.

For engineers reviewing the LPC1113FHN33/201 datasheet, LPC1113FHN33/201 pinout, LPC1113FHN33/201 application, or LPC1113FHN33/201 equivalent, this page delivers verified electrical specs, validated HVQFN33 terminal mapping, confirmed low-power operation modes, and real-world substitution guidance for industrial firmware development and BOM optimization.

Technical Context

The LPC1113FHN33/201 implements an ARM Cortex-M0 core with NVIC and system tick timer, paired with a dedicated Power Management Unit enabling Sleep, Deep-sleep, and Deep power-down modes. It uses a 12 MHz internal RC oscillator trimmed to ±1 % accuracy as primary clock source, optionally augmented by external crystal (1–25 MHz) or PLL for full 50 MHz CPU operation.

Peripheral integration includes a single UART with fractional baud rate generation and RS-485 support, one Fast-mode Plus I²C-bus interface (1 Mbit/s), one SPI controller with FIFO, four general-purpose timers (two 32-bit, two 16-bit), and a 10-bit ADC with configurable channel selection across eight pins - all mapped to 28 GPIOs in the HVQFN33 package.

FAQ

What is the maximum operating frequency of the LPC1113FHN33/201?

The LPC1113FHN33/201 operates at a maximum CPU frequency of 50 MHz. This is achieved using the on-chip PLL, which can be clocked from either the 12 MHz internal RC oscillator (trimmed to ±1 %) or an external crystal (1–25 MHz). The PLL eliminates need for high-frequency crystals while maintaining timing precision for real-time tasks.

Does the LPC1113FHN33/201 support In-Application Programming (IAP)?

Yes, the LPC1113FHN33/201 supports In-Application Programming via its on-chip bootloader. This allows firmware updates to be performed dynamically during runtime over UART or I²C interfaces - a key capability for remote maintenance in eMetering and smart lighting deployments where physical access is limited.

How many ADC channels does the LPC1113FHN33/201 provide, and what is their resolution?

The LPC1113FHN33/201 integrates a 10-bit successive approximation ADC with input multiplexing across up to eight pins (AD[7:0]). All eight channels are accessible in the HVQFN33 package, enabling simultaneous monitoring of multiple analog sensors - such as thermistors, current shunts, or light-dependent resistors - in compact embedded systems.

What debug interface does the LPC1113FHN33/201 use, and how many pins are required?

The LPC1113FHN33/201 uses Serial Wire Debug (SWD), requiring only two pins: SWDIO (bidirectional data) and SWCLK (clock). This two-wire interface replaces JTAG, reducing PCB routing complexity and pin count while supporting full firmware download, breakpoint setting, and real-time variable inspection during development and field diagnostics.

Is the LPC1113FHN33/201 compatible with extended temperature ranges?

No, the LPC1113FHN33/201 is rated for the industrial temperature range of −40 °C to +85 °C ('F' grade). For extended operation up to +105 °C, NXP offers the 'J' grade variant LPC1113JHN33/203 - which shares identical electrical specifications and pinout but undergoes additional qualification testing for higher thermal reliability.
