HMS88T1608L/16L INTRODUCTION The HMS88T1608L/16L, a member of the standard HMS88T16XYZ family, are a serial access microcontrollers especially designed for very large volume and cost competitive smart cards applications. The HMS88T1608L/16L are based on an 8 bit CPU core and include on chip memories: 384 bytes RAM, 16K bytes ROM, 8176/16384 bytes EEPROM structured in two main sectors to be used in different combinations, as described below. As all the other HMS88T16XYZ family members, the HMS88T1608L/16L are fully compatible with the ISO standards for smart card applications. The HMS88T1608L/16L can be delivered as: either in sawn or un-sawn 6inch wafers, 180 micron thickness as well as in micromodule package. Reliability data related to the HMS88T1608L/16L products manufactured using Hynix 0.7µm CMOS EEPROM technology guarantees data retention up to 10 years and endurance up to 300,000 erase/write cycles.
