smart card clock frequency At startup, there should be a ratio of 372 between the CLK frequency and the baud rate. Then, you can negociate higher speeds using the PPS protocol (this allows you to change this ratio, and also eventually use clock frequencies above 5MHz). Goodluck my friend. Depending on the image you would like to print and the quality of your .

At startup, there should be a ratio of 372 between the CLK frequency and the baud rate. Then, you can negociate higher speeds using the PPS protocol (this allows you to change this ratio, and also eventually use clock frequencies above 5MHz).Clock frequency and bit rate There is a linear relationship between the bit rate on the I/O line and the clock frequency provided by the clock interface device on CLK. Any clock frequency . At startup, there should be a ratio of 372 between the CLK frequency and the baud rate. Then, you can negociate higher speeds using the PPS protocol (this allows you to change this ratio, and also eventually use clock frequencies above 5MHz).

Clock frequency and bit rate There is a linear relationship between the bit rate on the I/O line and the clock frequency provided by the clock interface device on CLK. Any clock frequency between 7kHz and 50kHz may be chosen for the reset sequence.The Teridian 73S8009CN is the world’s first single-chip smart card electrical interface circuit that supports all types of smart cards: 5V, 3V and 1.8V, including traditional ISO-7816-3 asynchronous and synchronous type 1 and type 2, as well as USB, ISO-7816-12 cards.♦ Automatic Card Activation and Deactivation Controlled by Dedicated Internal Sequencer ♦ I/O Lines from Host Directly Level Shifted for Smart Card Communication ♦ Flexible Card Clock Generation, Supporting External Crystal Frequency Divided by 1, 2, 4, or 8 ♦ High-Current, Short-Circuit and High-Temperature Protection ♦ Low Active .I/O Lines from Host Directly Level Shifted for Smart Card Communication. Flexible Card Clock Generation, Supporting External Crystal Frequency Divided by 1, 2, 4, or 8. High-Current/Short-Circuit and High-Temperature Protection.

As per the ISO 7816 standard - maximum frequency of clk should be less than 5MHz with default fi and di values. with this configuration maximum speed attaniable is 9600 (With system clock 160Mhz and Clock UART will be 5 Mhz).

There are two commonly used clock speeds, 3.5795 MHz and 4.9152 MHz. The lower speed is most commonly used to date in Europe but this may change in the future. One may be tempted to ask why these strange frequencies were chosen, why not just a straight 5 MHZ.a smart card and how to use an MCU to communicate with it. For ease of use, a graphic user interface (GUI) is provided as an example. There are many types of IC cards. The communication method determines if the cards are contact cards or contactless (wireless) cards.The device has multiple power saving modes and also supports power saving in the smartcard itself by “clock stop” or lowering clock frequency to lowest allowable levels per the ISO7816 - 3 standard.

A contactless smart card includes an embedded smart card secure microcontroller or equivalent intelligence, internal memory and a small antenna and communicates with a reader through a contactless radio frequency (RF) interface. At startup, there should be a ratio of 372 between the CLK frequency and the baud rate. Then, you can negociate higher speeds using the PPS protocol (this allows you to change this ratio, and also eventually use clock frequencies above 5MHz).Clock frequency and bit rate There is a linear relationship between the bit rate on the I/O line and the clock frequency provided by the clock interface device on CLK.
