NXP Semiconductors LPC8N04FHI24Z

Overview

LPC8N04FHI24Z from NXP Semiconductors is a 32-bit ARM Cortex-M0+ microcontroller with integrated NFC/RFID ISO 14443 Type A interface, 32 kB flash, 8 kB SRAM, and ultra-low-power operation down to <50 nA in battery-off mode. It supports energy harvesting from NFC fields, OTA firmware updates via NFC, and operates across 1.72 V–3.6 V supply or passive NFC power for contactless sensor and control applications.

For engineers reviewing the LPC8N04FHI24Z datasheet, LPC8N04FHI24Z pinout, LPC8N04FHI24Z application, or LPC8N04FHI24Z equivalent, key selection considerations include NFC-powered wake-up capability, 12 GPIO with high-drive (20 mA) support on four pins, I2C-bus fast-mode (400 kbit/s), embedded temperature sensor (±1.5 °C accuracy), and deep power-down mode with configurable wake sources including RF field detection.

Technical Context

The LPC8N04FHI24Z integrates an ARM Cortex-M0+ core with Nested Vectored Interrupt Controller (NVIC), Serial Wire Debug (SWD), and system tick timer, running at up to 8 MHz from an internal 8 MHz FRO trimmed to ±2 % accuracy. Its clock architecture includes a dedicated 32.768 kHz timer oscillator for RTC and wake-up timing.

Power management is handled by an integrated Power Management Unit (PMU) supporting five operational states - active, sleep, deep sleep, deep power-down, and battery off - with automatic source selection between VDDBAT and NFC rectified power. The PMU enables <50 nA quiescent current in battery-off mode and provides BOD detection at 1.8 V on the VDD_ALON domain.

FAQ

What is the maximum system clock frequency supported by the LPC8N04FHI24Z?

The LPC8N04FHI24Z supports a maximum system clock frequency of 8 MHz, derived from its internal 8 MHz factory-trimmed free-running oscillator (FRO) with ±2 % accuracy. Lower frequencies (4 MHz, 2 MHz, etc.) are selectable via clock divider settings, though some peripheral features may be disabled at reduced clock speeds per the datasheet.

Does the LPC8N04FHI24Z require an external crystal or resonator?

No, the LPC8N04FHI24Z does not require an external crystal or resonator. It uses two internal RC oscillators: an 8 MHz system FRO for CPU and digital peripherals, and a 32.768 kHz timer FRO for RTC and wake-up timing. Both are factory-trimmed and fully functional without external components.

Can the LPC8N04FHI24Z operate without a battery?

Yes, the LPC8N04FHI24Z can operate entirely from NFC field energy via its LA/LB antenna terminals. In passive mode, it supports up to 2 MHz system clock and full NFC communication, enabling battery-free use cases such as smart tags and disposable diagnostics - verified in the official datasheet Rev. 1.4.

How many GPIO pins does the LPC8N04FHI24Z have, and which support high drive?

The LPC8N04FHI24Z provides 12 GPIO pins (PIO0_0 through PIO0_11). Four of these - PIO0_3, PIO0_7, PIO0_10, and PIO0_11 - are designated high-current pads capable of sourcing or sinking up to 20 mA each, enabling direct drive of LEDs or small actuators without external drivers.

Is the LPC8N04FHI24Z compatible with standard ARM Cortex-M0+ development tools?

Yes, the LPC8N04FHI24Z is fully compatible with industry-standard ARM Cortex-M0+ development tools, including Keil MDK, ARM GCC, and MCUXpresso IDE. It supports Serial Wire Debug (SWD) via PIO0_10 (SWCLK) and PIO0_11 (SWDIO), and includes NVIC and system tick timer for seamless integration into existing ARM toolchains.
