4 / 32 page  NXP Semiconductors Product Specification Security Transponder (HITAG2) PCF7936AS 2010 May 04 4 CONFIDENTIAL 1 FEATURES • Security Transponder for use in contactless authentication applications • Data transmission and energy supply via LF link • 32 bit quasi unique device identification (serial number) and product type identification. • Fast mutual authentication, 39ms • 48 bit Secret Key • 256 bit EEPROM for user data storage (128 bit) and device configuration/personalization (128 bit) • EEPROM read/write protection features • 20 years non-volatile data retention • More than 100 000 EEPROM erase/write cycles • Once the memory has been erased by UV, access is denied • Read Only emulation modes (H400x, ISO 11784/85 and PCF7931) • Excellent sensitivity in read and write mode • Automotive temperature range: -40°C to +85°C • Leadless plastic stick package 2 GENERAL DESCRIPTION The PCF7936AS is a high performance automotive proof Security Transponder for vehicle Immobilization applications, where the transponder has to identify itself towards the basestation as an authorized device. The Security Transponder derives its power supply from the magnetic field (LF field) established by the basestation. No additional battery supply is needed. Data is transmitted by modulating the LF field. The Security Transponder features secure contactless authentication, employing a Secret Key and a random number in order to cipher any communication between the device and the basestation. The secure contactless authentication is ideally suited for vehicle immobilization applications. In addition, the device features a factory programmed quasi unique serial number that also serves as product type identification. If desired, the device may be operated as a Read/write transponder with access control by password or as a Read Only transponder. 3 ORDERING INFORMATION EXTENDED PACKAGE TEMPERATURE TYPE NUMBER NAME DESCRIPTION OUTLINE VERSION RANGE (°C) PCF 7936AS/3851 SOT3851 leadless plastic stick package SOT385-1 -40°C to +85°C PCF 7936AS/3851/C SOT3851 leadless plastic stick package SOT385-1 -40°C to +85°C |
