Product details
Overview
LPC1102LVUKZ from NXP Semiconductors is a 32-bit ARM Cortex-M0 microcontroller designed for ultra-low-voltage embedded control in space-constrained portable devices, featuring 32 kB flash, 8 kB SRAM, an 8-bit ADC with 6-channel input multiplexing, Fast-mode Plus I²C (1 Mbit/s), UART with fractional baud rate generation, and operation at up to 50 MHz CPU frequency within a 1.65–1.95 V supply range.
For engineers reviewing the LPC1102LVUKZ datasheet, LPC1102LVUKZ pinout, LPC1102LVUKZ application, or LPC1102LVUKZ equivalent, this device supports rapid prototyping of battery-powered human-interface and sensor-edge applications requiring deterministic interrupt latency, low-power deep-sleep mode (≤1.6 µA), and compact wafer-level packaging for mobile accessories and active cables.
Technical Context
The LPC1102LVUKZ integrates an ARM Cortex-M0 core with nested vectored interrupt controller (NVIC) supporting up to 13 GPIO-based wake-up sources and four programmable priority levels. Its memory subsystem includes 32 kB on-chip flash with 256-byte page erase and 8 kB SRAM, both accessible via AHB bus for zero-wait-state execution at 50 MHz.
Peripheral integration centers on low-voltage compatibility: Fast-mode Plus I²C with high-current sink drivers on SCL/SDA, UART with 16-byte FIFOs and RS-485/9-bit support, one SPI/SSP controller with 8-frame FIFOs, four counter/timers (two 32-bit, two 16-bit), and an 8-bit ADC sampling at up to 10 kS/s across six analog inputs - all operating natively from a single 1.65–1.95 V rail.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC1114LVFHN24/303 | Same ARM Cortex-M0 core, 32 kB flash, 8 kB SRAM, but in HVQFN24 package (4×4 mm) with 20 GPIO pins and 6-channel ADC. | Requires larger PCB area; lacks WLCSP25's ultra-compact footprint but offers better thermal dissipation for sustained 50 MHz operation. | Select when board space permits and higher GPIO count or improved thermal performance is needed over extreme miniaturization. |
| LPC11U14FHN24/203 | ARM Cortex-M0 with USB 2.0 device controller, 32 kB flash, 8 kB SRAM, HVQFN24 package - adds native USB PHY and descriptors but removes Fast-mode Plus I²C. | Enables direct USB HID connectivity without external transceiver; trades I²C speed for USB endpoint functionality in plug-and-play peripherals. | Select when USB device class compliance (e.g., keyboard/mouse) is mandatory and I²C speed >400 kbit/s is not required. |
Compared with LPC1114LVFHN24/303 and LPC11U14FHN24/203, the LPC1102LVUKZ uniquely delivers WLCSP25 packaging with Fast-mode Plus I²C in a 1.65–1.95 V system - making it the only option for ultra-thin, battery-constrained designs needing high-speed sensor bus communication without USB or thermal headroom.

FAQ
What is the maximum operating frequency of the LPC1102LVUKZ?
The LPC1102LVUKZ operates at a maximum CPU frequency of 50 MHz. This speed is achieved using either the internal 12 MHz RC oscillator (trimmed to ±2.5 % accuracy over –20 °C to +85 °C) or an external crystal (1–25 MHz) with PLL multiplication. The device maintains full functionality across its specified 1.65–1.95 V supply range at this frequency.
Does the LPC1102LVUKZ support USB connectivity?
No, the LPC1102LVUKZ does not include a USB controller or physical transceiver. It provides UART, SPI/SSP, and Fast-mode Plus I²C interfaces for peripheral communication. For USB-enabled designs, engineers should consider alternative NXP parts such as the LPC11U series (e.g., LPC11U14FHN24/203), which integrate a full-speed USB 2.0 device controller.
How many ADC channels does the LPC1102LVUKZ support, and what is its resolution?
The LPC1102LVUKZ integrates an 8-bit successive approximation ADC with input multiplexing across six pins (AD0–AD5), consistent with its WLCSP25 package configuration. The ADC operates over the full 0 V to VDD range and achieves a maximum sampling rate of 10 kSamples/s, supporting burst conversion and optional trigger modes based on GPIO transitions or timer match events.
What debug interface does the LPC1102LVUKZ use, and how many pins are required?
The LPC1102LVUKZ uses Serial Wire Debug (SWD), a 2-pin ARM-standard debug interface requiring only SWCLK and SWDIO signals. This eliminates the need for a dedicated reset pin during debugging and reduces test point count - ideal for space-constrained WLCSP25 layouts. SWD supports full run-control, memory access, and breakpoint functionality via standard CMSIS-DAP or J-Link probes.
What is the deep-sleep current consumption of the LPC1102LVUKZ, and how is wake-up implemented?
The LPC1102LVUKZ achieves ≤1.6 µA deep-sleep current consumption with RTC disabled. Wake-up is supported via dedicated start logic using up to 13 functional GPIO pins configured as edge- or level-sensitive interrupt sources. The device resumes execution in under 5 µs, enabling rapid response to external events while preserving battery life in intermittent-operation applications.
