Product details
Overview
HTSICH4801EW/V7 from NXP Semiconductors is a contactless identification transponder IC in the HITAG S family, operating at 100–150 kHz with integrated 210 pF resonance capacitor (±5%), 2048-bit EEPROM memory, and 48-bit encrypted authentication. It enables secure animal ID, laundry automation, and keg logistics using inductive coupling without external power.
For engineers reviewing the HTSICH4801EW/V7 datasheet, HTSICH4801EW/V7 pinout, HTSICH4801EW/V7 application, or HTSICH4801EW/V7 equivalent, key selection considerations include its wafer-level Au-bumped die form factor, ISO 11784/85 compliance, 100,000 write cycles, Transponder Talks First mode support, and 10-year data retention under ≤55 °C ambient conditions.
Technical Context
The HTSICH4801EW/V7 implements a passive RF interface with no external power supply, deriving energy and clock from inductive coupling to a reader via its integrated 210 pF capacitance and external coil. It supports both Reader Talks First and Transponder Talks First modes with configurable data length and timing.
Its digital core executes a fast anticollision protocol (100 tags in 3.2 s), Manchester/Bi-phase coding for uplink, 100% ASK with Binary Pulse Length Coding for downlink, and CRC-8 error detection. Memory access supports Page (32-bit) and Block (128-bit) reads/writes, with authentication enabled via 48-bit secret key and challenge-response handshake.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 2048-bit EEPROM organized in 64 pages × 32 bits; enables storage of extended tag data for multi-field animal ID or asset tracking. |
| Operating frequency | 100–150 kHz; compatible with low-frequency RFID infrastructure used in animal ID and industrial logistics systems. |
| Input capacitance | 199–221 pF (typ. 210 pF); integrates resonant tuning capacitor, eliminating need for external components in coil-based antenna design. |
| Data rates (uplink) | 2 kBit/s, 4 kBit/s, or 8 kBit/s; selectable for trade-off between read speed and field robustness in dense tag environments. |
| Write endurance | 100,000 erase/write cycles; supports long-term reprogramming in reusable asset tagging applications like beer kegs or laundry tags. |
| Data retention | 10 years at ≤55 °C ambient; ensures reliable data persistence in outdoor or temperature-variable deployments. |
| Authentication | 48-bit secret key + challenge-response; prevents cloning and unauthorized memory access in brand protection or regulated animal ID systems. |
Pinout & Package
HTSICH4801EW/V7 is supplied as an Au-bumped die on sawn 8" wafer, with two terminals (IN1 and IN2) forming the RF interface. No external power pins or digital I/O are present - operation is fully passive and inductively coupled.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1 | RF input terminal | Connects to one end of external LC resonant coil; forms half of passive RF interface for power harvesting and bidirectional communication. |
| IN2 | RF input terminal | Connects to other end of external LC resonant coil; completes inductive coupling path and defines input capacitance (210 pF ±5%) with IN1. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated resonance capacitor | 210 pF ±5% eliminates need for external tuning capacitor, reducing BOM count and PCB footprint in embedded tag designs. |
| Fast anticollision protocol | Identifies 100 tags in 3.2 seconds, enabling high-throughput inventory scanning in livestock management or warehouse logistics. |
| Secure memory lock | Hardware-enforced write-protection per page/block prevents accidental or malicious overwrites in deployed animal ID or brand protection tags. |
| Transponder Talks First (TTF) mode | User-configurable data length and coding allows autonomous broadcast without reader polling - ideal for fixed-location sensor tags or pigeon race timing. |
| ISO 11784/85 compliance | Fully compliant with international animal identification standard, enabling direct integration into government-regulated livestock tracking systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar contactless transponder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HTSICH5601EW/V7 | 256-bit EEPROM memory; identical package, capacitance, frequency, and protocol stack. | Suitable for basic UID-only or low-data applications (e.g., simple pet ID), not extended data logging. | Select when memory requirement is ≤256 bits and cost sensitivity outweighs scalability needs. |
| HTSH4801ETK | HVSON2 surface-mount package (3 × 2 × 0.85 mm); same 2048-bit memory and electrical specs but with solderable 2-pin terminals. | Used in module-based or PCB-integrated designs where wafer die bonding is impractical. | Choose for automated assembly or rigid tag substrates requiring standardized SMT placement instead of wafer-level integration. |
Compared with HTSICH5601EW/V7, HTSICH4801EW/V7 provides 8× more user memory for richer data payloads, while HTSH4801ETK offers identical memory capacity in a manufacturable HVSON2 package - making HTSICH4801EW/V7 optimal for high-volume, ultra-compact wafer-level tag embedding where memory depth and minimal footprint are critical.

FAQ
What is the primary function of the HTSICH4801EW/V7?
The HTSICH4801EW/V7 is a passive contactless transponder IC that operates without a battery, harvesting energy from a reader's magnetic field to power its 2048-bit EEPROM and execute secure read/write commands. Its primary function is to serve as a tamper-resistant, ISO-compliant identification node in animal ID, logistics, and brand protection systems - and HTSICH4801EW/V7 achieves this through integrated resonance capacitance, 48-bit authentication, and TTF mode support.
Does the HTSICH4801EW/V7 require external components to operate?
No, the HTSICH4801EW/V7 integrates a 210 pF ±5% resonance capacitor between its IN1 and IN2 terminals, eliminating the need for external tuning capacitors in standard LC coil configurations. Only an external inductor (coil) is required to form the resonant circuit - and HTSICH4801EW/V7 is optimized for use with Qcoil = 20 and Lcoil = 7.5 mH per the datasheet.
How does the HTSICH4801EW/V7 support secure data access?
The HTSICH4801EW/V7 implements 48-bit secret key–based encrypted authentication using a challenge-response protocol: after UID selection, the reader sends a 32-bit random number and secret data stream; the HTSICH4801EW/V7 computes and returns a 32-bit encrypted response. This prevents replay attacks and unauthorized memory access - and HTSICH4801EW/V7 enforces this via hardware-locked keys and secure memory lock functionality.
What memory organization does the HTSICH4801EW/V7 use?
The HTSICH4801EW/V7 organizes its 2048-bit EEPROM into 64 pages of 32 bits (4 bytes) each, grouped into 16 blocks of 4 pages. Access is supported at page (32-bit) or block (128-bit) granularity, with dedicated configuration and UID pages - and HTSICH4801EW/V7 uses this structure to enable efficient data segmentation for multi-field applications like animal health records or keg service history.
Is the HTSICH4801EW/V7 compatible with existing HITAG infrastructure?
Yes, the HTSICH4801EW/V7 maintains full protocol compatibility with HITAG 1 infrastructure, including command set, anticollision algorithm, and modulation schemes (100% ASK downlink, strong ASK uplink with Manchester/Bi-phase coding). It extends the ecosystem with higher memory and security - and HTSICH4801EW/V7 operates seamlessly with legacy readers certified for HITAG 1 and HITAG 2, requiring no firmware or hardware upgrades.
