Product details
Overview
LPC1114LVFHI33/303 from NXP Semiconductors is a 32-bit ARM Cortex-M0 microcontroller in HVQFN33 package, operating at up to 50 MHz with 32 kB flash, 8 kB SRAM, 8-channel 8-bit ADC, UART, SPI/SSP, Fast-mode Plus I²C (1 Mbit/s), and 27 GPIO pins - deployed in portable medical electronics and active cables for low-power embedded control.
For engineers reviewing the LPC1114LVFHI33/303 datasheet, LPC1114LVFHI33/303 pinout, LPC1114LVFHI33/303 application, or LPC1114LVFHI33/303 equivalent, key selection criteria include its 1.65–1.95 V single-supply operation, Deep-sleep mode current ≤1.6 µA, 5 µs wake-up time, and support for UART fractional baud rate generation and I²C Fast-mode Plus with high-current sink on SCL/SDA.
Technical Context
The LPC1114LVFHI33/303 integrates an ARM Cortex-M0 core with NVIC, Serial Wire Debug, and system tick timer, paired with a dedicated AHB-peripheral GPIO block enabling accelerated bit-level port writes and edge/level-sensitive interrupts on up to 18 pins. Its clock system combines a 12 MHz ±2.5% internal RC oscillator, 1–25 MHz crystal oscillator, programmable watchdog oscillator (9.4 kHz–2.3 MHz), and PLL for CPU frequency scaling.
Peripherals are mapped via the IOCON block to shared pins: UART uses PIO1_6/RXD and PIO1_7/TXD (with DTR on PIO2_0), SPI0 uses PIO0_2/SSEL0, PIO0_6/SCK0, PIO0_8/MISO0, and PIO0_9/MOSI0, while the 8-channel ADC exclusively supports inputs AD0–AD7 on pins PIO0_11, PIO1_0–PIO1_4, PIO1_10, and PIO1_11 - all confirmed for HVQFN33 package only.

FAQ
What is the maximum operating frequency and voltage range of the LPC1114LVFHI33/303?
The LPC1114LVFHI33/303 operates at up to 50 MHz CPU frequency with a single 1.65 V to 1.95 V supply. Its internal 12 MHz RC oscillator is trimmed to ±2.5 % accuracy across −20 °C to +85 °C, and the PLL allows full-speed operation without requiring a high-frequency crystal. This voltage range is strictly defined for low-voltage operation and must not be exceeded to ensure reliable flash programming and ADC performance.
Does the LPC1114LVFHI33/303 support I²C Fast-mode Plus, and how is it enabled?
Yes, the LPC1114LVFHI33/303 supports I²C Fast-mode Plus (1 Mbit/s) on pins PIO0_4/SCL and PIO0_5/SDA. High-current sink capability is activated only when the Fast-mode Plus bit is set in the corresponding IOCON register - default configuration uses standard I²C drive strength. This feature ensures robust communication on buses with >400 pF capacitance, common in multi-drop cable and accessory applications.
How many ADC channels does the LPC1114LVFHI33/303 support, and what is their resolution and sampling rate?
The LPC1114LVFHI33/303 integrates an 8-bit successive approximation ADC with eight input channels (AD0–AD7), accessible only on the HVQFN33 package. It achieves up to 10 kSamples/s with measurement range 0 V to VDD (1.65–1.95 V). Specifications are validated across −40 °C to +85 °C, and each channel has a dedicated result register to reduce interrupt latency during burst conversions.
What debug interface does the LPC1114LVFHI33/303 provide, and is JTAG supported?
The LPC1114LVFHI33/303 provides Serial Wire Debug (SWD) via SWDIO and SWCLK pins - a 2-pin ARM-standard interface supporting full programming, breakpointing, and real-time memory inspection. JTAG is not implemented; SWD offers equivalent debug capability with reduced pin count and lower PCB routing complexity, aligning with the device's emphasis on minimal footprint and low-cost design.
Can the LPC1114LVFHI33/303 wake from Deep-sleep mode using GPIO interrupts, and how many pins support this?
Yes, the LPC1114LVFHI33/303 wakes from Deep-sleep mode in ≤5 µs using dedicated start logic inputs on up to 13 GPIO pins - including PIO0_0 through PIO0_11, PIO1_0 through PIO1_5, and PIO1_7. These pins retain interrupt capability in Deep-sleep, enabling immediate response to external events like button presses or sensor triggers without continuous polling, thereby maximizing energy efficiency in battery-powered systems.
