2/3 ST19XT34 hardware description this ST19XT34, a member of the st19x platform, is a serial access microcontroller especially de- signed for very large volume and cost effective se- cure portable applications. the chip includes also a map which is based on a 1088 bits processor architecture. it processes modular multiplication, squaring and additional calculations up to 2176 bit operands. internal modular arithmetic processor (map) and des accelerator are designed to speed up crypto- graphic calculations using public key algorithms and secret key algorithms. this product is based on a stmicrolectronics 8 bit cpu and includes on chip memories: user rom, user ram and user eeprom with state of the art security features. rom, ram and eeprom memories can be con- figured into partitions with customized access rules. access from any memory area to another are pro- tected by hardware firewalls. access rules are user defined and can be selected by mask options or during the life of the product. the chip includes a des accelerator which is ac- cessible via cryptographic system rom software library. as with all the other st19x products, serial inter- faces fully compatible with the iso7816 standard for smartcard applications are available. in addition, the chip includes an 2.0 standard usb serial interface and 2 serial access iso7816-3 i/os. a crc calculation block is also available and is di- rectly accessible by the user. this product is manufactured using an advanced highly reliable st cmos eeprom technology. figure 2. block diagram internal bus memory access firewall i/o 2 x serial inter- face gnd 8 bit cpu 3 x 8 bit timers crc module clk clock gene- rator module vcc gun a & gun b system rom, map and des firewall ram user rom system rom and crypto libraries des accele- rator map 290 secu- rity admin. reset usb inter- face eeprom d+ d-
3/3 ST19XT34 software development software development and firmware generation (rom and options) are supported by a compre- hensive set of development tools, dedicated at de- velopment and validation of softwares: ? smartcard ics emulator, ? st19x simulation package, ? scdevtools environment for all windows tm based stations, ? powerful c/c++ compiler and debugger are also available (third party tools). cryptographic libraries for an easy and sufficient use of the modular arithmetic processor (map), st proposes a com- plete set of firmware subroutines. this library is lo- cated in a specific rom area. this library saves the operating system designer from coding first layer functions and allows the designer to concen- trate on algorithms, public key cryptography and secret key cryptography protocols implementa- tion. this library contains firmware functions for: asymmetrical algorithms ? loading and unloading parameters and results to or from the map ? calculating montgomery constants ? basic mathematics including modular squaring and multiplication for various lengths ? modular exponentiation using or not the chinese remainder theorem (crt) ? more elaborate functions such as rsa signatures and verifications for modulo length up to 2176 bits long, dsa signature and authentication. ? full internal key generation for signatures/ verifications. this guarantees that the secret key will never be known outside the chip and contributes to overall system security. ? long random number generation ? rsa up to 2176 bits ? dsa up to 1088 bits ? sha-1 ? rsa key generation symmetrical algorithms ? des, triple des, desx computations ? cbc chaining mode ? loading/unloadings from/to registers are secured against spa information furnished is believed to be accurate and reliable. however, stmicroelectronics assumes no responsibility for the co nsequences of use of such information nor for any infringement of patents or other rights of third parties which may result from its use. no license is granted by implication or otherwise under any patent or patent rights of stmicroelectronics. specifications mentioned in this publicati on are subject to change without notice. this publication supersedes and replaces all information previously supplied. stmicroelectronics prod ucts are not authorized for use as critical components in life support devices or systems without express written approval of stmicroelectro nics. the st logo is a registered trademark of stmicroelectronics. all other names are the property of their respective owners ? 2003 stmicroelectronics - all rights reserved bull cp8 patents stmicroelectronics group of companies australia - belgium - brazil - canada - china - czech republic - finland - france - germany - hong kong - india - israel - italy - japan - malaysia - malta - morocco - singapore - spain - sweden - switzerland - united kingdom - united states www.st.com
