Product details
Overview
RF-HDT-AJLE-G1 from Texas Instruments is a 13.56 MHz ISO/IEC 15693- and ISO/IEC 18000-3-compliant passive RFID transponder IC designed for proximity identification in smart labels. It features 256-bit user EEPROM (8 × 32-bit blocks), factory-programmed 64-bit UID, AFI support, and operates with ASK/FSK uplink modulation. Used in asset tagging, electronic ticketing, and baggage handling systems where contactless read/write at sub-meter range is required.
For engineers reviewing the RF-HDT-AJLE-G1 datasheet, RF-HDT-AJLE-G1 pinout, RF-HDT-AJLE-G1 application, or RF-HDT-AJLE-G1 equivalent, this page delivers verified electrical specs, die-level mechanical data, antenna interface requirements, memory lock behavior, and real-world deployment constraints - all confirmed from TI's SCBU047 reference guide.
Technical Context
The RF-HDT-AJLE-G1 implements full-duplex communication per ISO/IEC 15693, supporting both 1-out-of-4 and 1-out-of-256 downlink coding and ASK/FSK uplink with high/low data rate options. Frame synchronization and CRC checksum ensure reliable command-response integrity across multi-tag environments.
Its 23.5 pF input capacitance and 6.5–15.5 kΩ LC circuit impedance requirement define antenna design boundaries; operation requires precise resonance tuning to 13.56 MHz with VANT ≤ 7 V unmodulated and IANT_DC ≤ 10 mA. The die integrates irreversible block locking (user- and factory-lockable) and supports anticollision via UID-based inventory.
Key Specifications

| ANT2 | Antenna terminal 2 | Connects to opposite end of external LC resonator - completes RF energy harvesting path. |
| TDAT | Test data pad | Used during wafer probe testing only - not functional in final inlay assembly. |
| GND | Ground reference | Provides substrate reference for internal circuitry - must be connected to antenna ground plane if used. |
Key Features
| Feature | Design Value |
|---|---|
| ISO/IEC 15693 Compliance | Fully implements mandatory commands (Inventory, Read_Single_Block, Write_Single_Block, Lock_Block) and optional AFI - ensures interoperability with standard HF readers. |
| Factory-Locked UID | 64-bit immutable identifier programmed during manufacturing - eliminates UID collision risk in dense tag fields. |
| Two-Level Block Locking | Supports both user-lockable (U) and factory-lockable (F) blocks using ISO-defined security status bits - enables mixed-read/write and read-only data regions. |
| Low-Power Operation | 25 μA supply current at minimum VANT - extends effective read range under weak-field conditions typical in metal-rich or shielded environments. |
| ESD Immunity | 2.5 kV HBM on ANT1/ANT2, 2.0 kV on TDAT/GND - protects against handling damage during inlay fabrication and label conversion. |

FAQ
What is the exact die size and bump configuration of RF-HDT-AJLE-G1?
The RF-HDT-AJLE-G1 die measures 996 × 996 μm ±15 μm (excluding scribe line) with gold bumps over nickel under-bump metallization. Bump height is 20 μm ±3 μm, hardness exceeds HV 450, and shear strength is >400 cN - specifications confirmed in TI's SCBU047 mechanical die tables for the AJLE-G1 variant.
Does RF-HDT-AJLE-G1 support ISO/IEC 14443 or NFC Forum protocols?
No. RF-HDT-AJLE-G1 is strictly compliant with ISO/IEC 15693 and ISO/IEC 18000-3 standards only. It does not implement ISO/IEC 14443A/B, NFC Forum Type 1–5, or any proprietary NFC modes. Its command set, modulation schemes, and frame structure are defined exclusively for vicinity-card operation.
How is memory locking implemented on RF-HDT-AJLE-G1?
RF-HDT-AJLE-G1 supports two independent lock mechanisms: factory lock (F) for UID and AFI blocks, and user lock (U) for any of the eight 32-bit user memory blocks. Lock bits are stored in the Block Security Status byte per ISO 15693-3; once set, they are irreversible - no unlock or reset function exists in the RF-HDT-AJLE-G1 command set.
What antenna impedance range must be targeted for reliable RF-HDT-AJLE-G1 operation?
RF-HDT-AJLE-G1 requires an LC circuit impedance between 6.5 kΩ and 15.5 kΩ at 13.56 MHz, as specified in Table 2-2 of SCBU047. This range assumes the IC's 23.5 pF input capacitance is compensated by antenna parasitics; deviation outside this window reduces read range and increases bit error rate during uplink transmission.
Is RF-HDT-AJLE-G1 supplied as a packaged IC or bare die?
RF-HDT-AJLE-G1 is supplied as a bare die on sawn 200 mm wafers mounted on standard 8-inch FFC frames. It has no molded package, leadframe, or encapsulation - intended for direct die bonding onto etched aluminum or copper antennas in smart label inlay production.
