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.

Smartcard power supply

鈥?Selectable card V

: 1.8 V, 3 V, and 5 V
