Description
ST7LCRE4U1 and ST7LCRDIE6 are 8-bit
microcontrollers dedicated to smartcard reading
applications. They have been developed to be the
core of smartcard readers communicating
through USB link. Optimized for mass-market
applications, it offers a single integrated circuit
solution with very few external components.
