NXP Semiconductors HTEV800,122

Overview

HTEV800 from Philips Semiconductors is a long-range RFID evaluation kit for 125 kHz HITAG systems, comprising a read/write device, dual-rail ±15 V power supply, external 340 × 360 mm flat-cable antenna, RS232 interface cable, AC mains cable, DC power cable, HITAG 1 and HITAG 2 transponders, and CD-ROM with demonstration software, C source code, and user manual.

For engineers reviewing the HTEV800 datasheet, HTEV800 pinout, HTEV800 application, or HTEV800 equivalent, this kit enables rapid prototyping of long-range contactless identification systems in access control, asset tracking, and industrial automation where 1 m operating range and cryptographic security are required.

Technical Context

The HTEV800 implements a complete 125 kHz RFID system architecture centered on the HITAG core module, supporting both HITAG 1 (with anticollision) and HITAG 2 protocols. Its signal processing unit suppresses up to two harmonic disturbers to maintain range stability in electromagnetically noisy environments.

Hardware integration requires connection to a PC via RS232 (COM1 or COM2), powered by an AC mains input (110 V/60 Hz or 240 V/50 Hz selectable), and driven through a dedicated ±15 V DC supply. The included flat-cable antenna is mechanically fixed at 340 × 360 mm dimensions and electrically matched for optimal 125 kHz coupling.

FAQ

What is the HTEV800 used for?

The HTEV800 is a complete evaluation kit for developing and testing long-range 125 kHz RFID systems using Philips' HITAG 1 and HITAG 2 transponders. It includes hardware, cables, antennas, and software tools-enabling engineers to validate reader performance, implement custom applications using provided C source code, and verify cryptographic security features without designing from scratch. The HTEV800 accelerates proof-of-concept work in access control and logistics.

Does the HTEV800 support both HITAG 1 and HITAG 2 transponders?

Yes, the HTEV800 explicitly supports both HITAG 1 and HITAG 2 transponders, including HITAG 1's anticollision feature. This dual-protocol capability allows developers to evaluate interoperability across legacy and enhanced transponder versions within the same 125 kHz infrastructure. The HTEV800's read/write device uses the HITAG core module to ensure full functional compatibility with both families.

What are the power requirements for the HTEV800?

The HTEV800 requires AC mains input at either 110 V/60 Hz or 240 V/50 Hz (user-selectable via rear-panel marking), feeding a dedicated power supply unit that delivers ±15 V DC to the read/write device. This dual-voltage design ensures global usability in lab environments. The HTEV800 does not operate from USB or low-voltage DC sources-it relies entirely on its supplied AC/DC conversion system.

Can I use a custom antenna with the HTEV800?

Yes, the HTEV800 supports custom antennas, but proper impedance matching and tuning at 125 kHz are essential. Philips provides Application Note "Antenna design for the HITAG long range system" to guide implementation. When replacing the included 340 × 360 mm flat-cable antenna, users must verify resonant frequency, Q-factor, and magnetic field strength to avoid range degradation or protocol failure. The HTEV800's interface remains RS232 regardless of antenna choice.

What software is included with the HTEV800?

The HTEV800 includes a CD-ROM with RFIDDEMO demonstration software, evaluation software, portable 'C' source code for customization, and the "RFIDDEMO HITAG evaluation software" user manual. The software runs on IBM-PC compatibles (286+ CPU, 640 KB RAM, RS232 port) and enables transponder read/write, memory access, security key management, and protocol diagnostics. All software is designed exclusively for use with the HTEV800 hardware stack.
