LPC1316FHN33,551 概要

The NXP LPC1316FHN33,551 is a 32-bit Arm Cortex-M3 entry-level microcontroller operating at up to 72 MHz, with 48 KB of on-chip flash memory and a 32-pin HVQFN (7x7 mm) exposed-pad package.

An entry-level 32-bit MCU is an integrated circuit that combines a processor core, program flash, SRAM, and mixed-signal peripherals on a single die, sitting in the product hierarchy between 8-bit MCUs and high-performance Cortex-M4/M7 devices. The LPC1316 belongs to the NXP LPC1300 family, which targets embedded applications requiring a high level of integration and low power consumption.

Key features include the Arm Cortex-M3 core with a 3-stage pipeline and Harvard architecture with separate instruction and data buses, CPU speeds up to 72 MHz, 48 KB flash, a USB 2.0 full-speed device controller, USART serial interfaces, and an internal prefetch unit supporting speculative branching for improved execution efficiency.

Technically, the Cortex-M3 core integrates an NVIC interrupt controller, SysTick timer, and enhanced debug features, while the LPC1300 peripheral set adds fast GPIO, 10-bit ADC, and serial connectivity on a single 3.3 V supply rail (2.5 V to 3.3 V operating range per distributor data).

Typical applications include USB-connected embedded devices, industrial control nodes, consumer appliances, and battery-powered instrumentation where 8-bit MCUs lack headroom but full Cortex-M4 performance is unnecessary.

Design consideration: the 32-HVQFN exposed pad must be soldered to a ground plane for both thermal dissipation and signal integrity; verify the 2.5 V to 3.3 V supply window before reusing a 5 V-tolerant design.

This page synthesizes verified distributor pricing, pin-compatible LPC13xx family alternatives, and practical design notes not consolidated in the manufacturer datasheet.

主な用途

LPC1316FHN33,551 の用途: 6 件s: USB Embedded Devices, Industrial Control Nodes, Battery-Powered Instrumentation, Consumer Appliance Control, Sensor Hubs and IoT Edge Nodes, Test and Measurement Accessories.

🔌

USB Embedded Devices

The LPC1316FHN33,551 fits USB-connected peripherals because it integrates a USB 2.0 full-speed device controller alongside the 72 MHz Cortex-M3 core, enabling HID, CDC, and vendor-class enumeration without an external PHY. Typical roles include USB sensors, dongles, and configuration interfaces where the 48 KB flash accommodates USB stack plus application firmware. The 3-stage pipeline and Harvard bus architecture sustain the throughput needed for bulk transfers, while the 32-HVQFN (7x7) exposed-pad package keeps the BOM and board area compact for handheld form factors.

🏭

Industrial Control Nodes

In factory automation nodes, the LPC1316FHN33,551 provides deterministic Cortex-M3 execution at 72 MHz with USART links to PLC peripherals and sensor buses. The 48 KB flash holds protocol handlers such as Modbus RTU with margin for OTA feature updates, and the entry-level peripheral integration reduces external component count on dense I/O boards. Operating from a 2.5 V to 3.3 V rail, it pairs cleanly with 3.3 V industrial logic; the exposed-pad HVQFN improves thermal margin inside sealed control cabinets where passive cooling only is available.

🔋

Battery-Powered Instrumentation

Portable instruments benefit from the LPC1300 family's low power consumption and high integration: one chip supplies the 72 MHz processing core, flash, SRAM, ADC, and serial interfaces, minimizing quiescent overhead versus multi-chip solutions. The 48 KB flash supports data-logging tables and calibration constants in firmware, while the Cortex-M3 sleep modes permit long battery life in handheld meters and environmental loggers. Designers should budget current for the USB block when enabled and leverage clock-gating of unused peripherals to reach the lowest standby figures cited in the NXP datasheet.

📺

Consumer Appliance Control

White-goods and small-appliance controllers use the LPC1316FHN33,551 as a cost-effective 32-bit upgrade path from 8-bit MCUs: the 72 MHz Cortex-M3 core runs PID motor-control loops with headroom, and the on-chip USART communicates with display and touch-front-end boards. The 32-HVQFN (7x7) surface-mount package supports automated assembly and compact main-board layouts. The 48 KB flash accommodates multiple operating modes and localization variants, and NXP's long-lifecycle industrial MCUs simplify repeated production builds over multi-year appliance programs.

🧩

Sensor Hubs and IoT Edge Nodes

As a sensor aggregation node, the LPC1316FHN33,551 collects I2C/SPI sensor streams through its GPIO and USART peripherals while executing local filtering on the 72 MHz core, reducing upstream data volume. The 48 KB flash holds protocol stacks and buffering routines, and the 2.5 V to 3.3 V supply range matches common Li-ion-regulated rails. Although it lacks on-chip radio, pairing it with a BLE or sub-GHz module yields a low-cost edge node; the HVQFN exposed pad supports dense multi-chip layouts typical of module-style IoT boards.

🔧

Test and Measurement Accessories

USB bench accessories such as data-acquisition dongles and programmer pods map well to the LPC1316FHN33,551: the full-speed USB device controller streams samples to host software, the 72 MHz Cortex-M3 handles packetization and timing, and 48 KB flash stores calibration and firmware-update bootloaders. The 32-HVQFN (7x7) package suits compact probe-body enclosures, and the exposed pad simplifies grounding to the analog front end. The 3-stage pipeline delivers consistent latency for trigger and timestamp functions required in measurement firmware.

What is the maximum CPU frequency of LPC1316FHN33,551?
The LPC1316FHN33,551 operates at CPU frequencies of up to 72 MHz. According to NXP's product page, the Arm Cortex-M3 CPU incorporates a 3-stage pipeline, uses a Harvard architecture with separate local instruction and data buses plus a third bus for peripherals, and includes an internal prefetch unit supporting speculative branching for efficient code execution.
How much flash memory does the LPC1316FHN33,551 have?
The LPC1316FHN33,551 contains 48 KB (48K x 8) of on-chip flash program memory, as listed by DigiKey. This places it in the middle of the LPC13xx flash lineup, which ranges from 32 KB (LPC1315) to 64 KB (LPC1343). The 48 KB capacity suits USB HID/CDC class applications and modest control firmware compiled with C and standard peripheral libraries.
What is the price of LPC1316FHN33,551?
The LPC1316FHN33,551 is priced from approximately $1.1762 per unit at LCSC as of 2026-10-10. Octopart lists 6 distributors offering bulk discounts, so volume pricing typically drops below the single-unit price. XAIPART tier pricing as of 2026-10-10 starts at $1.18 (qty 1), $1.06 (qty 10), and $0.95 (qty 100); verify current stock and lead time before ordering.
Is LPC1316FHN33,551 in stock and where can I buy it online?
Yes, the LPC1316FHN33,551 is in stock: LCSC lists it as in-stock (product C1339207), DigiKey states "Buy now, ships today", and Hotenda also stocks it. XAIPART offers direct ordering with tier pricing as of 2026-10-10. Availability across these channels means standard lead times apply rather than factory lead times of several months.
What is the difference between LPC1316FHN33 and LPC1343FHN33?
The primary difference is flash capacity: the LPC1316FHN33 has 48 KB flash while the LPC1343FHN33 has 64 KB flash. Both share the same Arm Cortex-M3 core running up to 72 MHz, USB device support, USART interfaces, and the same 32-pin HVQFN (7x7) package with matching pinout, making the LPC1343 a pin-compatible upgrade when firmware outgrows 48 KB.
Can LPC1317FHN33 replace LPC1316FHN33,551?
Yes. The LPC1317FHN33 is a pin-compatible drop-in replacement from the same LPC1300 family in the same 32-HVQFN (7x7) package. It offers more flash (64 KB vs 48 KB) with the same 72 MHz Cortex-M3 core and peripheral set. Firmware compiled for the LPC1316 runs on the LPC1317 after updating the device header and linker script; verify the SRAM size delta against your memory map.
What is the best drop-in replacement for LPC1316FHN33,551?
The best same-family drop-in replacements are LPC1317FHN33 (64 KB flash upgrade) and LPC1315FHN33 (32 KB flash, cost reduction), both in the identical 32-HVQFN package from NXP. If flash headroom is the concern, LPC1343FHN33 is the traditional choice. All three are pin-to-pin compatible, so no PCB rework is needed; only software device identification headers and memory configuration need updating during the firmware build.
Is there a cross-brand equivalent for the LPC1316FHN33,551 in the same package?
For a cross-brand equivalent, engineers typically consider STMicroelectronics STM32F0-series or Microchip PIC32 parts, but no verified pin-to-pin cross-brand equivalent in the 32-HVQFN (7x7) footprint was found in the cross-reference data reviewed for this page. MCU core peripherals are vendor-specific, so cross-brand migration normally requires PCB rework. For a no-rework path, stay within the NXP LPC1300 family, which shares the exact footprint and pinout.
When should I choose LPC1316FHN33,551 over LPC1343FHN33?
Choose the LPC1316FHN33,551 when your firmware fits within 48 KB of flash and you want the lower unit cost of the smaller-die variant. Choose the LPC1343FHN33 (64 KB flash) when you need USB mass-storage class support, larger RTOS images, or growth headroom, since code size tends to expand over a product's lifetime. Both share the same footprint, so moving between them later requires only a BOM change, not a layout revision.
Is the LPC1316FHN33,551 suitable for USB device applications?
Yes, the LPC1316FHN33,551 integrates a USB 2.0 full-speed device controller, making it well suited for USB HID, CDC, and custom-class devices. Combined with the 72 MHz Cortex-M3 core and on-chip flash, it handles enumeration and data endpoints without external USB PHY circuitry. DigiKey and NXP both highlight the USB device peripheral as a defining feature of the LPC13xx series for connected embedded applications.
Where can I download the LPC1316FHN33,551 datasheet PDF?
The authoritative datasheet for the LPC1316FHN33 is available from NXP's official product page at nxp.com/part/LPC1316FHN33, which links the current document revision. Mirror copies exist on aggregator sites such as Alldatasheet and DigChip, but always download from NXP to ensure you have the latest revision covering electrical characteristics, pinout, and register descriptions for the LPC1300 family.
What is the LPC1316FHN33,551 pinout and package?
The LPC1316FHN33,551 comes in a 32-pin HVQFN package measuring 7x7 mm with an exposed pad, per DigiKey's listing. The exposed pad must connect to ground for thermal and electrical performance. For the full pin-by-pin assignment (GPIO port mapping, USB D+/D-, USART TX/RX, ADC inputs, and power pins), consult the pin configuration chapter of the official NXP LPC131x datasheet rather than third-party diagrams.
What are the key specifications of LPC1316FHN33,551 that engineers should know?
The LPC1316FHN33,551 is a 32-bit Arm Cortex-M3 microcontroller from NXP running at up to 72 MHz with 48 KB flash in a 32-pin HVQFN (7x7 mm) exposed-pad package. It operates from a 2.5 V to 3.3 V supply, integrates a USB full-speed device controller and USART interfaces, and uses a 3-stage Harvard pipeline with speculative-branching prefetch. It targets entry-level, low-power embedded applications per NXP's product documentation.
Is LPC1316FHN33,551 RoHS compliant and lead-free?
The LPC1316FHN33,551 is offered with RoHS-compliant, lead-free manufacturing per NXP's standard product flow; the ,551 ordering suffix denotes the standard tray-packaged RoHS part. XAIPART lists compliance status as verified against NXP product data, but for formal regulatory documentation (REACH declarations, material composition reports), download the certificate from NXP's compliance portal using the exact ordering part number LPC1316FHN33,551.
What is the lead time for LPC1316FHN33,551?
The LPC1316FHN33,551 is readily available: DigiKey indicates same-day shipping from stock, and LCSC lists in-stock inventory as of 2026-10-10, so distributor lead time is effectively immediate for standard quantities. For direct factory orders from NXP, lead time depends on volume and scheduling agreements and should be confirmed with NXP or your franchised distributor. Octopart shows 6 distributors carrying the part, providing sourcing redundancy.
Does the LPC1316FHN33,551 require special PCB layout considerations?
Yes. The 32-HVQFN exposed pad on the package bottom should be soldered to a grounded copper pad on the PCB for reliable thermal dissipation and reduced ground inductance; use an array of thermal vias to the ground plane. Decouple each VDD pin with 100 nF ceramic capacitors placed within a few millimeters of the pins, and route USB D+/D- as a 90-ohm differential pair when the USB device interface is used.

選定ガイド

Choose the LPC1316FHN33,551 when your application needs a 72 MHz Cortex-M3 with USB device support and your firmware fits in 48 KB flash - it offers the best price-to-memory balance in the LPC1300 family. Choose the LPC1315FHN33,551 (32 KB) for cost-optimized designs with lean firmware, and step up to the LPC1317FHN33,551 or LPC1343FHN33,551 (64 KB) when you need USB mass-storage class support, larger RTOS images, or field-upgrade headroom; all three are pin-to-pin compatible with the LPC1316 in the same 32-HVQFN (7x7) package, so PCB rework is never required. Stay within the LPC1300 family for substitutions: no verified cross-brand pin-compatible equivalent exists in this footprint, and cross-brand MCU migration (e.g., to STM32F0 or PIC32) requires layout changes and driver rework regardless. Confirm the 2.5 V to 3.3 V supply window fits your power tree before committing.

  • Balanced 48 KB flash capacity (vs LPC1315FHN33,551)
  • Lower cost than 64 KB siblings (vs LPC1343FHN33,551)
  • Footprint upgrade path (vs LPC1317FHN33,551)

設計ノート

Solder the HVQFN exposed pad to a PCB ground pad with a 3x3 (or larger) via array to the internal ground plane. The exposed pad is the primary ground return for the die; an unsoldered or cold-soldered pad commonly causes erratic USB operation and elevated ground bounce even though the peripheral ring pins appear properly connected. Follow NXP's HVQFN application soldering guidance for stencil aperture design.

Decouple every VDD pin with a 100 nF ceramic capacitor placed within 3 mm of the pin, plus one bulk 4.7 uF to 10 uF capacitor near the supply entry. The LPC1300 operates from 2.5 V to 3.3 V, so verify that upstream regulator accuracy plus IR drop keeps the rail inside this window under peak USB-transmit load. Do not power the part from a 5 V rail without level shifting and a 3.3 V LDO.

Pin-compatible LPC13xx family swaps (LPC1315/1316/1317/1343) still require firmware updates: change the device header in your build, review the linker script for differing flash/SRAM sizes, and re-check the flash configuration word. Assuming a binary compiled for the LPC1316 runs unchanged on a larger-flash sibling is a common source of boot failures on first power-up after a BOM substitution.
