Product details
Overview
LPC1311FHN33/01 from NXP Semiconductors is a 32-bit ARM Cortex-M3 microcontroller in HVQFN33 package, operating up to 72 MHz with 8 kB flash, 4 kB SRAM, and integrated I²C-bus (Fast-mode Plus), UART, four timers, and 10-bit ADC. It targets low-power embedded control in metering, lighting, and alarm systems.
For engineers reviewing the LPC1311FHN33/01 datasheet, LPC1311FHN33/01 pinout, LPC1311FHN33/01 application, or LPC1311FHN33/01 equivalent, key selection criteria include its 33-pin HVQFN thermal-enhanced package, power profile support (LPC1300L series), Windowed Watchdog Timer (WWDT), and brownout detect with four forced-reset thresholds - all confirmed for this exact variant.
Technical Context
The LPC1311FHN33/01 implements an ARM Cortex-M3 core with Harvard architecture, 3-stage pipeline, and internal prefetch unit enabling speculative branching. It integrates a Power Management Unit (PMU) supporting Sleep, Deep-sleep, and Deep power-down modes with wake-up via up to 40 functional pins.
This variant belongs to the LPC1300L series, distinguishing it from base LPC1300 parts by enhanced power profiles, programmable pseudo open-drain GPIO mode, internal pull-ups to full VDD, and WWDT - all explicitly specified for LPC1311/01 and LPC1313/01 in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3, 72 MHz max - enables deterministic real-time control with NVIC and low-latency interrupt handling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC1313FHN33/01 | 32 kB flash, 8 kB SRAM, same package and peripherals - no USB, but adds second SSP controller. | Preferred where larger firmware image or dual SPI peripheral access is required (e.g., dual sensor buses). | Select when memory headroom or additional serial interface is needed; identical power features and pinout. |
| LPC1342FHN33 | 16 kB flash, 4 kB SRAM, includes USB Device controller and on-chip PHY - lacks WWDT and power profiles. | Suitable for USB-connected diagnostic tools or firmware update interfaces, not safety-critical low-power systems. | Choose only if USB device functionality is mandatory and WWDT/power optimization are secondary. |
Compared with LPC1311FHN33/01, LPC1313FHN33/01 offers double memory without sacrificing power features, while LPC1342FHN33 trades WWDT and power profiles for USB - making LPC1311FHN33/01 optimal for cost-sensitive, ultra-low-power embedded control where deterministic reset behavior is essential.

FAQ
What is the maximum CPU frequency supported by the LPC1311FHN33/01?
The LPC1311FHN33/01 operates at a maximum CPU frequency of 72 MHz, achieved using the system PLL driven by either the internal 12 MHz RC oscillator (trimmed to ±1 % accuracy) or an external crystal up to 25 MHz. This frequency is fully supported across its 2.0–3.6 V supply range and industrial temperature grade.
Does the LPC1311FHN33/01 include USB functionality?
No, the LPC1311FHN33/01 does not include USB functionality. USB Device support is exclusive to the LPC1342/43 variants per the official datasheet. The LPC1311FHN33/01 retains full UART, I²C, SSP, and timer peripherals - making it ideal for non-USB control applications where cost and power efficiency are prioritized.
What distinguishes the LPC1311FHN33/01 from the standard LPC1311FHN33?
The LPC1311FHN33/01 belongs to the LPC1300L series and adds four key enhancements over LPC1311FHN33: power profiles for optimized active/sleep current, four-level brownout forced reset, Windowed Watchdog Timer (WWDT), and internal pull-up resistors tied to full VDD. These are confirmed in Table 2 and Section 1 of the datasheet.
How many ADC channels does the LPC1311FHN33/01 support, and what is the resolution?
The LPC1311FHN33/01 integrates a 10-bit successive approximation ADC with 8 input channels (AD0–AD7), mapped to dedicated GPIO pins including PIO0_11, PIO1_0 through PIO1_4, PIO1_10, and PIO1_11. Each channel supports single-ended sampling with programmable conversion triggers via timers or software.
Is the LPC1311FHN33/01 pin-compatible with other members of the LPC13xx family in HVQFN33 package?
Yes, the LPC1311FHN33/01 shares identical pinout and package dimensions (HVQFN33, 7 × 7 × 0.85 mm) with LPC1313FHN33/01, LPC1342FHN33, and LPC1343FHN33. However, functional differences exist - e.g., USB pins are no-connect on LPC1311FHN33/01, and SSP1 is absent - so firmware and schematic design must align with the specific variant's peripheral set.
