Product details
Overview
LPC11A11FHN33/001 from NXP Semiconductors is a 32-bit ARM Cortex-M0 microcontroller in HVQFN33 package, operating at up to 50 MHz with 8 kB flash, 2 kB SRAM, and 512 B EEPROM. It integrates a 10-bit ADC (8 channels), 10-bit DAC, analog comparator, temperature sensor, and UART/SSP/I²C interfaces. Used in industrial control and remote monitoring where low-power mixed-signal processing is required.
For engineers reviewing the LPC11A11FHN33/001 datasheet, LPC11A11FHN33/001 pinout, LPC11A11FHN33/001 application, or LPC11A11FHN33/001 equivalent, key selection criteria include its HVQFN33 footprint, 28 GPIO count, 50 MHz CPU clock, integrated analog peripherals, and support for Serial Wire Debug (SWD) and ISP programming.
Technical Context
The LPC11A11FHN33/001 implements an ARM Cortex-M0 core with NVIC and system tick timer, paired with a configurable analog/mixed-signal subsystem. Its clock generation includes a 1–25 MHz crystal oscillator, 12 MHz ±1% IRC, and PLL for CPU scaling up to 50 MHz.
Digital peripherals include two SSP controllers (up to 25 Mbit/s), Fast-mode Plus I²C (1 Mbit/s), RS-485-capable USART, four timers (CT16B0/1, CT32B0/1), and programmable Windowed Watchdog Timer with dedicated low-power oscillator.

FAQ
What is the maximum operating frequency of the LPC11A11FHN33/001?
The LPC11A11FHN33/001 operates at a maximum CPU frequency of 50 MHz, achievable using the internal 12 MHz IRC oscillator with PLL multiplication or an external crystal (1–25 MHz) fed into the SysOsc. This frequency is fully supported across the specified temperature range (−40 °C to +85 °C) and supply voltage (2.6–3.6 V).
Does the LPC11A11FHN33/001 support in-system programming (ISP)?
Yes, the LPC11A11FHN33/001 supports In-System Programming via its built-in bootloader, enabling flash and EEPROM updates over UART using standard ISP commands. The bootloader resides in 16 kB boot ROM and requires no external programmer - essential for field firmware upgrades in deployed LPC11A11FHN33/001 units.
How many analog-to-digital converter (ADC) channels does the LPC11A11FHN33/001 provide?
The LPC11A11FHN33/001 features an 8-channel, 10-bit successive approximation ADC with input multiplexing across PIO0_6 to PIO0_15. Each channel supports hardware triggering via ATRG0/ATRG1 signals and includes dedicated sample-and-hold circuitry - confirmed in the LPC11Axx datasheet Rev. 4 section 2.2.3.
What debug interface does the LPC11A11FHN33/001 use?
The LPC11A11FHN33/001 uses Serial Wire Debug (SWD) as its primary debug interface, implemented on pins PIO0_5 (SWCLK) and PIO0_10 (SWDIO). JTAG boundary scan is also supported via TCK/TMS/TDO/TDI pins, but SWD is recommended for minimal pin count and full debug functionality in the LPC11A11FHN33/001 design.
Is the LPC11A11FHN33/001 pin-compatible with other LPC11Axx variants in HVQFN33 package?
Yes, the LPC11A11FHN33/001 is pin-compatible with LPC11A12FHN33/101 and LPC11A14FHN33/301 in the HVQFN33 package - all share identical pin numbering, electrical characteristics, and peripheral mappings. This allows direct substitution in existing designs when higher memory capacity is needed without PCB revision.
