ST19NA18 Datasheet - STMicroelectronics

Description
   The product, member of the ST19N platform, is a serial access microcontroller specially designed for cost-effective secure portable applications.
   It is manufactured using an advanced highly reliable ST CMOS EEPROM technology.
   It is based on the STMicroelectronics 8-bit CPU already implemented on the ST19X product family and includes on-chip memories: User ROM, User RAM and EEPROM with state-of-the-art security features. ROM, RAM and EEPROM memories can be configured into partitions with customized access rules.
