ST19XL34V2 2 / 4 hardware description the product, member of the st19x platform, is a serial access microcontroller specially designed for cost effective secure portable applications. it is manufactured using an advanced highly reli- able st cmos eeprom tec hnology. it is based on a stmicroelectronics 8 bit cpu and includes on-chip memories: user rom, user ram and eeprom with state of the art security fea- tures. rom, ram and eeprom memories can be configured into partitions with customized access rules. an additional st rom contains all st provided functions and libraries. 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 an enhanced des accelerator which is accessible via cryptographic software li- braries located in st rom. 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 enhanced des accelerator are designed to speed up cryptographic calculations using public key al- gorithms and secret key algorithms. as with all the other st19x products, a serial inter- face fully compatible with the iso7816 standard for smartcard applications is available. a crc calculation block is also available and is di- rectly accessible by the user. figure 2. block diagram internal bus memory access firewall i/o 1 serial i/o inter- face gnd 8 bit cpu 3 x 8 bit timers crc module clk clock gene- rator module st rom, map and edes firewall ram user rom st rom and crypto library edes accele- rator map 432 vcc gun a & gun b secu- rity admin. reset eeprom
