Product details
Overview
LPC1101LVUKZ from NXP Semiconductors is a 32-bit ARM Cortex-M0 microcontroller designed for ultra-low-power, space-constrained embedded applications. It operates at up to 50 MHz, integrates 32 kB flash and 2 kB SRAM, features an 8-bit ADC with 6 input channels, one UART, one SPI/SSP, one Fast-mode Plus I²C interface, four general-purpose timers, and 21 GPIO pins - all within a 1.65–1.95 V single-supply WLCSP25 package.
For engineers reviewing the LPC1101LVUKZ datasheet, LPC1101LVUKZ pinout, LPC1101LVUKZ application, or LPC1101LVUKZ equivalent, this page delivers verified technical context, validated pin functions, real-world use cases in portable electronics, and confirmed alternative parts with documented functional and packaging differences.
Technical Context
The LPC1101LVUKZ implements the ARM Cortex-M0 core with Nested Vectored Interrupt Controller (NVIC), Serial Wire Debug (SWD), and system tick timer - enabling deterministic interrupt handling and low-overhead firmware debugging. Its clock system combines a 12 MHz ±2.5% internal RC oscillator, crystal oscillator support (1–25 MHz), programmable watchdog oscillator (9.4 kHz–2.3 MHz), and PLL for CPU operation up to 50 MHz without external high-frequency crystals.
Power management includes Sleep and Deep-sleep modes, achieving ≤1.6 µA in Deep-sleep with 5 µs wake-up time via up to 13 GPIO pins. All I/O pins support configurable pull-up/pull-down resistors and open-drain mode; PIO0_4/SCL and PIO0_5/SDA provide high-current sink capability when Fast-mode Plus I²C is enabled.
Key Specifications

|---|---|
| CPU Core | ARM Cortex-M0, 32-bit RISC architecture optimized for deterministic real-time control and minimal code footprint in 8/16-bit replacement designs. |
| Max Operating Frequency | 50 MHz - enables fast signal processing and responsive peripheral handling while maintaining sub-2 V supply compatibility. |
| Memory | 32 kB on-chip flash (256-byte page erase) + 2 kB SRAM - sufficient for compact firmware with bootloader and sensor data buffering. |
| Analog Input | 8-bit ADC with 6-channel multiplexing - supports basic voltage monitoring, battery sensing, or simple transducer interfacing at ≤10 kS/s. |
| Serial Interfaces | 1× UART (fractional baud rate, 16-byte FIFO), 1× SPI/SSP (25 Mbit/s master), 1× I²C (Fast-mode Plus, 1 Mbit/s) - covers common sensor, display, and communication needs. |

FAQ
What is the maximum operating frequency of the LPC1101LVUKZ?
The LPC1101LVUKZ operates at up to 50 MHz using its integrated PLL, which can be driven by either the internal 12 MHz RC oscillator or an external crystal (1–25 MHz). This frequency is fully supported across the 1.65–1.95 V supply range and enables real-time processing for sensor fusion and protocol handling without external clock sources.
Does the LPC1101LVUKZ support I²C Fast-mode Plus?
Yes, the LPC1101LVUKZ supports I²C Fast-mode Plus (1 Mbit/s) on pins PIO0_4/SCL and PIO0_5/SDA when configured via the IOCON register. These pins feature high-current sink drivers specifically enabled for Fast-mode Plus operation, improving noise immunity and bus drive capability beyond standard I²C.
How many ADC channels does the LPC1101LVUKZ have, and what is their resolution?
The LPC1101LVUKZ integrates a single 8-bit successive approximation ADC with input multiplexing across 6 pins (AD0–AD5), matching its WLCSP25 package pin count. The ADC operates from 0 V to VDD (1.65–1.95 V), supports burst conversion, and achieves up to 10 kSamples/s - suitable for battery monitoring and basic environmental sensing.
What debug interface does the LPC1101LVUKZ provide?
The LPC1101LVUKZ includes Serial Wire Debug (SWD) with dedicated SWDIO and SWCLK pins (PIO1_3 and PIO0_10), supporting full JTAG-style debugging, flash programming, and real-time trace via standard ARM-compliant tools. No external debug adapter is needed beyond a SWD-compatible probe.
Is the LPC1101LVUKZ pin-compatible with other LPC11xxLV variants?
The LPC1101LVUKZ is pin-compatible with LPC1102LVUK in the WLCSP25 package, sharing identical pin functions and layout. However, it is not pin-compatible with HVQFN24 or HVQFN33 variants (e.g., LPC1112LVFHN24/003) due to differing pin counts, ball assignments, and peripheral mappings - PCB redesign is required for package migration.
