Product details
Overview
LPC1114FHN33/201 from NXP Semiconductors is a 32-bit ARM Cortex-M0 microcontroller in HVQFN33 package, operating at up to 50 MHz with 32 kB flash, 4 kB SRAM, one UART with RS-485 support, one I²C-bus interface (Fast-mode Plus), and 28 GPIO pins. It targets cost-sensitive embedded control in lighting, alarm systems, and white goods.
For engineers reviewing the LPC1114FHN33/201 datasheet, LPC1114FHN33/201 pinout, LPC1114FHN33/201 application, or LPC1114FHN33/201 equivalent, key selection criteria include flash/SRAM capacity, HVQFN33 thermal performance, UART RS-485 capability, I²C Fast-mode Plus compliance, and power profile availability for low-power operation.
Technical Context
The LPC1114FHN33/201 belongs to the LPC1100 series (non-L/non-XL variant), lacking power profiles, windowed watchdog timer, and second SPI interface. It uses the ARM Cortex-M0 core with NVIC and Serial Wire Debug, supports fractional baud rate generation in UART, and integrates a 10-bit ADC with up to 8 input channels.
Clock generation relies on a 12 MHz internal RC oscillator (±1 %), external crystal (1–25 MHz), and PLL for CPU frequencies up to 50 MHz. Power management includes Sleep, Deep-sleep, and Deep power-down modes, but excludes the boot ROM power profile function found in LPC1100L/XL variants.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC1114FHN33/202 | Includes power profiles in boot ROM for optimized low-power operation | Better suited for battery-powered devices requiring dynamic power scaling | Select when application demands runtime power mode switching via single API call |
| LPC1114FHN33/301 | 8 kB SRAM (vs. 4 kB) and same 32 kB flash; no power profiles | Preferred for firmware with large buffers, complex state machines, or RTOS usage | Select when memory-bound workloads exceed 4 kB SRAM capacity |
Compared with LPC1114FHN33/202, the LPC1114FHN33/201 lacks boot ROM power profiles-reducing code footprint but limiting runtime power optimization. Compared with LPC1114FHN33/301, it provides half the SRAM-sufficient for bare-metal applications but constraining for RTOS or large data buffers.

FAQ
What is the maximum operating frequency of the LPC1114FHN33/201?
The LPC1114FHN33/201 operates at a maximum CPU frequency of 50 MHz, achieved using 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 its specified temperature range (−40 °C to +85 °C) and supply voltage (1.8–3.6 V).
Does the LPC1114FHN33/201 support a second SPI interface?
No, the LPC1114FHN33/201 does not support a second SPI interface. As a member of the base LPC1100 series (not LPC1100L or LPC1100XL), it includes only one SPI controller (SPI0) with SSP features. The second SPI (SPI1) is exclusive to LPC1100L and LPC1100XL variants in LQFP48 packages.
What ADC resolution and input channel count does the LPC1114FHN33/201 provide?
The LPC1114FHN33/201 integrates a 10-bit successive approximation ADC with input multiplexing across up to 8 pins (AD0–AD7), all available on the HVQFN33 package. The ADC supports single-ended conversion only and includes dedicated result registers and burst mode for efficient sampling.
Is the LPC1114FHN33/201 pin-compatible with LPC1114FHN33/202?
Yes, the LPC1114FHN33/201 and LPC1114FHN33/202 share identical pinout, package (HVQFN33), and electrical specifications. The only functional difference is the inclusion of power profiles in boot ROM for the /202 variant; no PCB layout changes are required when substituting between these two parts.
What debug interface does the LPC1114FHN33/201 support?
The LPC1114FHN33/201 supports Serial Wire Debug (SWD) via dedicated SWDIO and SWCLK pins (PIO1_3 and PIO0_10), compatible with standard ARM Cortex-M debug probes. It does not support JTAG; SWD provides full program download, breakpoint, and real-time register access with minimal pin count.
