Product details
Overview
LPC1114LVFHN24/303 from NXP Semiconductors is a 32-bit ARM Cortex-M0 microcontroller in HVQFN24 package, operating at up to 50 MHz with 32 kB flash, 8 kB SRAM, 8-bit ADC (6-channel), UART, SPI/SSP, Fast-mode Plus I²C (1 Mbit/s), and 20 GPIO pins - designed for ultra-low-power mobile accessories and portable medical electronics.
For engineers reviewing the LPC1114LVFHN24/303 datasheet, LPC1114LVFHN24/303 pinout, LPC1114LVFHN24/303 application, or LPC1114LVFHN24/303 equivalent, this page delivers verified specifications, validated HVQFN24 pin mapping, confirmed 1.65–1.95 V single-supply operation, Deep-sleep mode current (≤1.6 µA), and real-world use cases in active cables and battery-powered sensing nodes.
Technical Context
The LPC1114LVFHN24/303 implements an ARM Cortex-M0 core with integrated NVIC, Serial Wire Debug, and system tick timer - all running from a single 1.65–1.95 V supply. Its clock system combines a 12 MHz ±2.5% internal RC oscillator, external crystal support (1–25 MHz), programmable watchdog oscillator (9.4 kHz–2.3 MHz), and PLL for CPU frequency scaling up to 50 MHz without high-frequency crystals.
Digital peripherals include four counter/timers (two 32-bit, two 16-bit) with match/capture functionality, GPIO configurable as edge/level interrupts, and high-current sink drivers on I²C pins for Fast-mode Plus compliance. Analog capability is limited to six 8-bit ADC inputs due to HVQFN24 package constraints, with sampling up to 10 kS/s and power-down mode.

The LPC1114LVFHN24/303 provides six 8-bit ADC input channels (AD0–AD5), as confirmed by Table 2 and Section 7.11 of the datasheet. The seventh and eighth channels (AD6, AD7) are only accessible on the HVQFN33 package variant (e.g., LPC1114LVFHI33/303).
What debug interface does the LPC1114LVFHN24/303 use?
The LPC1114LVFHN24/303 uses Serial Wire Debug (SWD) with two dedicated pins: SWCLK (pin 4) and SWDIO (pin 23). This 2-pin interface supports full debugging, flash programming, and real-time tracing - eliminating the need for JTAG headers in compact PCB layouts.
Is the LPC1114LVFHN24/303 suitable for battery-powered applications?
Yes, the LPC1114LVFHN24/303 is optimized for battery-powered use: it operates from a single 1.65–1.95 V supply, achieves ≤1.6 µA Deep-sleep current, wakes in ≤5 µs, and supports wake-up from 13 GPIO pins - making it ideal for intermittent-sensing devices like wireless sensors and portable medical tools.
