EMTG97-3 97KB Ultra Low Cost Flash Smart Card IC
Sep 27, 2018

EMTG97-3 97KB ultra low cost flash smart card IC
EMTG97-3 contact smart card is a member of a family of devices designed specifically for Smart Card applications. The CPU is software compatible with the industry standard 8051 8 bits microprocessor, to guarantee the maximum reuse of tested software. The hardware implementation of the core is a modern design not relying on microcode, with an increase of up to 3 times on a standard 8051's clocks per instruction.
EMTG97 is using superior flash memory SuperFlash Technology licensed from SST and SuperFlash is a registered trademark of SST (silicon storage technology Inc.)..
Various and powerful security mechanisms and design for security techniques embedded in this IC allow to meet security requirements of targeted application.
Flexible memory allocation to code or data makes this IC suitable for a large range of applications.
The new concept of General purpose memory GPNVM usable as well for code or data (EEPROM) provides a very cost effective implementation.
