ST19XS08 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 op- tions. the chip includes a des accelerator which is ac- cessible via cryptographic software libraries locat- ed in st rom. 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 i/o 1 x serial inter- face gnd 8 bit cpu 2 x 8 bit timers crc module clk clock gene- rator module vcc gun a & gun b ram user rom st rom and des library 349 secu- rity admin. reset eeprom st rom and des firewall memory access firewall des accele- rator
