Product details
Overview
LPC4072FET80K from NXP Semiconductors is a 32-bit ARM Cortex-M4 microcontroller designed for low-power embedded control applications. It operates at up to 120 MHz, integrates 64 kB flash, 24 kB SRAM, and 2048 B EEPROM, and supports USB Device-only functionality without Ethernet or LCD. It targets cost-sensitive industrial and consumer systems requiring compact footprint and deterministic real-time response.
For engineers reviewing the LPC4072FET80K datasheet, LPC4072FET80K pinout, LPC4072FET80K application, or LPC4072FET80K equivalent, this page delivers verified specifications, TFBGA80 package details, confirmed peripheral set (2x CAN, 4x UART, 12-bit ADC, DAC, RTC), and validated alternative options for migration or sourcing continuity.
Technical Context
The LPC4072FET80K implements an ARM Cortex-M4 core with hardware floating-point unit (FPU) disabled, Memory Protection Unit (MPU), and Nested Vectored Interrupt Controller (NVIC). Its multilayer AHB matrix enables concurrent CPU and DMA access to peripherals including GPDMA, UARTs, SSP, I²C, and timers.
Peripheral integration includes a 12-bit 8-channel ADC with DMA support, 10-bit DAC with dedicated timer, two analog comparators, quadrature encoder interface (QEI), motor control PWM, and ultra-low-power RTC with battery-backed registers and event recorder. The device lacks Ethernet MAC, LCD controller, and EMC - consistent with its LPC4072 variant designation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC4072FBD80 | LQFP80 package (12 mm × 12 mm) instead of TFBGA80; identical electrical specs and pin function mapping except for physical layout. | Preferred where manual soldering, test probing, or legacy LQFP tooling is required; less suitable for high-density or thermally constrained boards. | Select LPC4072FBD80 when board assembly uses reflow-only processes incompatible with fine-pitch BGA or when debug access to individual pins is critical. |
| LPC4074FBD80 | 128 kB flash, 40 kB SRAM, adds SD/MMC interface and second analog comparator; same TFBGA80/LQFP80 packaging options. | Supports larger firmware images, local data buffering, and dual-sensor analog front-ends - suitable for feature-rich edge nodes needing local storage. | Choose LPC4074FBD80 when future firmware expansion, FAT32 file system support, or redundant analog monitoring is required without changing PCB footprint. |
Compared with LPC4072FET80K, LPC4072FBD80 offers identical functionality in a more serviceable package, while LPC4074FBD80 provides scalable memory and peripheral headroom - both retain pin compatibility and software ecosystem alignment within the LPC40xx family.

FAQ
Does LPC4072FET80K include a hardware floating-point unit (FPU)?
No, the LPC4072FET80K variant does not integrate a hardware FPU. While the ARM Cortex-M4 core architecture supports optional FPU, NXP disables it in this specific part number to optimize die size and cost for deterministic control applications. Software-based floating-point operations remain fully supported via CMSIS-DSP libraries, and integer math performance is unaffected.
What is the maximum operating frequency of LPC4072FET80K?
The LPC4072FET80K operates at up to 120 MHz CPU frequency. This is achieved using the on-chip PLL driven by either the internal 12 MHz RC oscillator (trimmed to ±1 %) or an external crystal (1–25 MHz). The flash accelerator ensures zero-wait-state execution at full speed, maintaining real-time determinism.
Can LPC4072FET80K support USB Host or OTG functionality?
No, LPC4072FET80K supports USB 2.0 full-speed Device-only mode only. It lacks the dual-role PHY and associated host/OTG controller logic present in higher-tier LPC408x/7x variants. Applications requiring host capability must use LPC4078 or LPC4088 derivatives with H/O/D designation in Table 2.
Is the LPC4072FET80K pin-compatible with other LPC40xx family members in TFBGA80?
Yes, LPC4072FET80K shares identical pinout and ball assignment with LPC4072FBD80 (LQFP80) and LPC4074FBD80 (LQFP80) for all signal, power, and ground connections. However, functional differences exist - e.g., LPC4074FBD80 enables SD/MMC and extra comparator - so firmware and schematic design must verify peripheral enablement per variant.
What debug interfaces are supported by LPC4072FET80K?
LPC4072FET80K supports both JTAG and Serial Wire Debug (SWD) interfaces, along with serial trace output. It includes eight hardware breakpoints and four watchpoints, enabling full-cycle debugging, real-time variable inspection, and instruction trace analysis using standard ARM-compliant tools like Keil MDK or SEGGER J-Link.
