Description

The AT88SC101/102 family provides 1024 bits of serial E2PROM (Electrically Erasable and Programmable Read Only Memory) with additional security logic for use in secure smart card applications. The AT88SC101 is available in one 1024 x 1 bit memory zones, and the AT88SC102 is available in two 512 x 1 bit memory zones.

The security features of Atmel's AT88SC101/AT88SC102 include: data access only after validation of the security code permanent invalidation of device upon four consecutive false security code presentations read/write protection of certain memory zones device reset if power drops secure transport of devices using transport code compare sequence

The AT88SC101/AT88SC102 is manufactured using low-power CMOS technology and features its own internal high-voltage
pump for single voltage supply operation. The devices are guaranteed to 100,000 erase/write cycles and 100 year data retention. Endurance up to one-million
