Description
The ST7GEME4 is an 8-bit microcontroller
dedicated to smartcard reading applications. It
has been developed to be the core of smartcard
readers communicating through a serial or USB
link. It is pre-programmed using Gemplus
software, and offers a single integrated circuit
solution with very few external components.
