Product details
Overview
NT3H1101W0FHKH from NXP Semiconductors is an NFC Forum Type 2-compliant contactless tag IC with integrated I²C interface, 888-byte user EEPROM, 64-byte SRAM buffer, energy harvesting output (VOUT), and configurable field detection (FD) pin. It enables bidirectional data exchange between NFC readers and microcontrollers in zero-power or externally powered configurations, used in smart home appliances for firmware updates and device pairing.
For engineers reviewing the NT3H1101W0FHKH datasheet, NT3H1101W0FHKH pinout, NT3H1101W0FHKH application, or NT3H1101W0FHKH equivalent, this page delivers verified technical context, memory mapping behavior, arbitration logic, energy harvesting capability, and real-world use cases aligned to the XQFN8 package and 1k memory variant.
Technical Context
The NT3H1101W0FHKH integrates dual-interface arbitration using first-come-first-serve policy with status flag bits indicating RF or I²C bus busy state. Its RF interface complies with ISO/IEC 14443 Type A and NFC Forum Type 2, operating at 13.56 MHz with 106 kbit/s data rate and true anticollision support.
The I²C slave interface supports Standard (100 kHz) and Fast (400 kHz) modes, enabling direct EEPROM emulation and SRAM pass-through access. Memory includes 888 bytes of user EEPROM (222 pages × 4 bytes), static/dynamic lock bits, and 64-byte SRAM mapped at I²C block addresses F8h–FBh when VCC-powered.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Interface | NFC Forum Type 2 Tag compliant; enables passive communication with smartphones and NFC readers without external power. |
| Memory Capacity | 888 bytes user EEPROM (222 pages × 4 bytes); sufficient for full NDEF messages in consumer appliance configuration. |
| SRAM Buffer | 64 bytes volatile memory; eliminates EEPROM write endurance limits during frequent RF↔I²C data transfers in pass-through mode. |
| I²C Speed | Supports up to 400 kHz Fast Mode; allows sub-millisecond block writes (0.4 ms per 16-byte block to SRAM). |
| Energy Harvesting | VOUT pin supplies regulated voltage to external low-power devices (e.g., MCU sleep-mode wake-up); no separate power rail required. |
| Field Detection | Open-drain FD pin triggers on RF field presence, first communication start, or tag selection - enabling host system event awareness. |
| Operating Frequency | 13.56 MHz RF carrier; ensures interoperability with global NFC infrastructure and mobile devices. |
Pinout & Package
NT3H1101W0FHKH uses the XQFN8 package (SOT902-3): plastic, extremely thin quad flat, no leads, 1.6 × 1.6 × 0.6 mm body, 8 terminals. Central thermal pad is unconnected per NXP recommendation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (LA) | Antenna connection A | Connects to one end of external loop antenna coil; forms resonant LC tank with internal capacitance for RF energy coupling. |
| 2 (VSS) | GND reference | Common ground return for RF rectifier, I²C logic, and energy harvesting circuitry; must be low-impedance. |
| 3 (SCL) | I²C clock input | Accepts master-generated clock up to 400 kHz; synchronizes all I²C read/write operations to EEPROM or SRAM. |
| 4 (FD) | Field detection output | Open-drain signal pulled low upon RF field detection or communication start; drives external interrupt or wake-up logic. |
| 5 (SDA) | I²C bidirectional data | Carries address/data/control bits in half-duplex mode; supports standard I²C EEPROM register map access. |
| 6 (VCC) | External power supply | Enables I²C operation and unlocks SRAM access; powers internal logic and enables energy harvesting regulation. |
| 7 (VOUT) | Energy harvesting output | Delivers regulated DC voltage (typ. 2.7–3.3 V) derived from RF field; powers external microcontrollers or sensors. |
| 8 (LB) | Antenna connection B | Completes antenna loop connection; differential RF input pair with LA for optimal magnetic coupling efficiency. |
Key Features
| Feature | Design Value |
|---|---|
| Pass-through mode | Maps 64-byte SRAM into EEPROM address space for seamless RF ↔ I²C data exchange without EEPROM write cycling. |
| Configurable FD pin | Programmable trigger events (field presence, first comms, selection only) enable precise host system synchronization and power management. |
| Dynamic memory locking | Three dynamic lock bytes protect extended memory (pages 10h+) in 16-page granularity; irreversible via RF, resettable via I²C. |
| FAST READ command | Reads up to 1024 bytes in single frame (9235-bit max response); accelerates NDEF message retrieval from NFC readers. |
| True anticollision | Supports multiple NTAG I²C tags in same RF field; enables reliable identification and sequential addressing in multi-tag environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NFC + I²C interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NT3H1201W0FHK | 2k EEPROM (1904 bytes) vs. 1k; identical pinout, timing, and feature set; higher memory density for larger NDEF payloads. | Suitable where >888 bytes of user data (e.g., multi-language UI strings, extended sensor logs) must be stored in tag memory. | Select NT3H1201W0FHK when application requires >1 kB NDEF message capacity without changing PCB layout or firmware I²C driver. |
| ST25DV02K | 2-kbit EEPROM, I²C interface, RF field detection, but lacks SRAM buffer and pass-through mode; different memory organization and lock scheme. | Better suited for simple NFC-triggered control (e.g., ON/OFF toggle) rather than high-frequency bidirectional data transfer. | Choose ST25DV02K only if SRAM-assisted RF↔I²C throughput is not required and legacy ST ecosystem integration is prioritized. |
Compared with NT3H1101W0FHKH, NT3H1201W0FHK offers double user memory without trade-offs in speed or power, while ST25DV02K sacrifices SRAM acceleration and flexible memory mirroring for ST-specific toolchain compatibility.

FAQ
What is the memory capacity of NT3H1101W0FHKH?
The NT3H1101W0FHKH provides 888 bytes of user-accessible EEPROM memory (222 pages × 4 bytes), plus 64 bytes of volatile SRAM for high-speed RF↔I²C data buffering. The EEPROM retains data for 20 years with 500,000 write cycles, while the SRAM has unlimited endurance and is accessible only when VCC is applied.
Does NT3H1101W0FHKH support energy harvesting?
Yes, NT3H1101W0FHKH features integrated energy harvesting circuitry that delivers regulated DC voltage via the VOUT pin. This output can power external low-power devices such as microcontrollers in sleep mode, eliminating the need for a separate power source during NFC interaction.
How does the field detection (FD) pin function on NT3H1101W0FHKH?
The FD pin on NT3H1101W0FHKH is an open-drain output configurable to assert low on RF field presence, first communication start, or tag selection only. It enables host microcontrollers to detect NFC activity asynchronously and wake from low-power states without polling.
Can NT3H1101W0FHKH operate without external VCC?
Yes - NT3H1101W0FHKH operates in fully passive mode using only RF field power for contactless communication. However, I²C interface access, SRAM usage, and energy harvesting require VCC to be applied; RF-only functions remain active without it.
What is the purpose of the SRAM pass-through mode in NT3H1101W0FHKH?
The SRAM pass-through mode in NT3H1101W0FHKH maps the 64-byte SRAM into the EEPROM address space, allowing NFC readers to read/write data directly to SRAM without EEPROM write limitations. This enables rapid, high-cycle data exchange between RF and I²C interfaces during active VCC operation.
