KS88C9408
CMOS Microcontroller for
Smart Card Applications
OVERVIEW
The KS88C9408 single-chip CMOS micro-controller is
designed for low voltage smart card applications and
is fabricated using an advanced 0.65-micron CSMOS
process. Its fast and reliable 8-bit CPU is based on the
proven Zilog Super8
architecture.
The KS88C9408 has 8 Kbytes of EEPROM, 528
bytes of SRAM, 16 Kbytes of program ROM, a 16-bit
random number generator, an 8-bit basic timer, a
power-on reset circuit, asynchronous serial I/O
interface and numerous security options.
The time required to complete an EEPROM
erase/write operation is a fast 1.5 ms each (typical).
The serial I/O module supports fast data transfer rates
of 9.6, 19.2, and 38.4 Kbps.
For added data security and for easier programming,
EEPROM erase/write and serial I/O subroutines are
integrated in the KS88C9408 ROM.
The KS88C9408 either meets or exceeds all relevant
ISO standards.
