General Description
EM4830 integrated circuit is designed specifically for multi-application cards in access control, transportation and ticketing. It
offers dual multiprotocol interfaces to support the largest range of applications, thus combining contact and contact-less
interface technologies.
Due to integrated on-chip power switch EM4830 can be powered from contact or contactless interface. In contact power mode, the
device can communicate with both interfaces ISO7816 or ISO14443. In contactless mode, the device can provide energy, extracted
from the RF field, to external devices like CPUs or sensors.
The FLASH based architecture offers a very high degree of flexibility. A solution based on EM4830 can be rapidly and safely
deployed in the field offering a fast time to market. The need to support the emerging multifunction and dual interface cards
requires that the device can download an application under software control and run it when the device is in the field embedded in
a plastic card. This application can be in the form of a script to be executed by an interpreter or as raw binary code directly
executed by the processor.
Compatibility with the industry standard 8051 micro-controller guarantees the maximum availability of qualified software. The
hardware implementation of the core is a modern design not relying on microcode, with an increase of up to 4 times that of a
standard 8051's clocks per instruction.
