INTRODUCTION
The HMS88T1602/04/08, a member of the standard
HMS88T16XYZ family, are a serial access microcon-
trollers especially designed for very large volume and
cost competitive smart cards applications.
The HMS88T1602/04/08 are based on an 8 bit CPU
core and include on chip memories: 480 bytes RAM,
16K bytes ROM, 2048/4096/8176 bytes EEPROM
structed in two main sectors to be used in different
combination, as described below.
Reliability data related to the HMS88T1602/04/08
products manufactured using Hynix 0.7
m CMOS
EEPROM technology guarantees data retention up to
10 years and endurance up to 300,000 erase/write
cycles.
As all the other HMS88T16XYZ family members, the
HMS88T1602/04/08 are fully compatible with the ISO
standards for smart card applications.
The HMS88T1602/04/08 can be delivered as:
either in sawn or un-sawn 6inch wafers, 180 micron
thickness as well as in micromodule package.
