PRODUCT OVERVIEW
SAM87 PRODUCT FAMILY
Samsung's SAM87 family of 8-bit single-chip CMOS microcontrollers offers a fast and efficient CPU, a wide range of integrated peripherals, and various mask-programmable ROM sizes. Important CPU features include: -- Efficient register-oriented architecture -- Selectable CPU clock sources -- Release by interrupt of Idle and Stop power-down modes -- Built-in basic timer circuit with watchdog function
KS88C9408 MICROCONTROLLER
The KS88C9408 single-chip CMOS microcontroller is specially designed and packaged for "smart card" applications. The SAM87 CPU architecture supports Stop and Idle power-down modes for reduced power consumption. To increase the general-purpose register space, the physical internal register file is logically expanded. The KS88C9408 has 16-Kbyte of program memory (ROM), 8-Kbyte of data memory (EEPROM), 272-byte general-purpose register file and 256 bytes data buffer (SRAM). The following peripherals are integrated onchip: · · One 8-bit basic timer for internal reset and watchdog functions One 16-bit random number generator · · Asynchronous serial I/O interface (half-duplex) with selectable transmission baud rates EEPROM write inhibit features for data security
Data can be loaded into the EEPROM in units ranging from one byte to 32 bytes. A typical EEPROM erase or write operation takes 1.5 milliseconds. An up to 32 bytes area of the EEPROM can be used as chip and card information area. A simple yet effective hardware-level security feature based on voltage and frequency range detection circuits keeps data stored in EEPROM. The KS88C9408's 8-pin COB package and its serial I/O interface are fully compliant with ISO standards 7816, respectively.
