1. INTRODUCTION

The SPI SecureHead™ magnetic stripe reader can read 1, 2, or 3 tracks of magnetic stripe information.

When connected to the host, the SecureHead is completely compatible with SPI Specification. The raw

data or decoded data send to host through the SPI.

The SecureHead supports both unencrypted and encrypted data output. When the encryption is not

turned on, the decoded data can be formatted with preamble/postamble and terminator characters to

match the format expected by the host.

This document is to describe the electrical, firmware and mechanical information of SecureHead SPI

interface with Flexible Printed Circuit (FPC).

3. SPI OPERATION

This section describes the SPI (Serial Peripheral Interface), the SPI bus interface timing,

communication protocol, timeouts, and data output format.

3.1. SPI Data Transmission

A serial peripheral interface (SPI) is an interface that enables the serial exchange of data between two

devices, one called a master and the other called a slave. The host (master) generates the clock signal

(SPCK) to trigger data exchange on the SPI bus.

During each SPI clock cycle, the data is transmitted in both directions at the same time (full duplex

transmission)

on the MOSI line, the master sends a bit and the slave reads it

on the MISO line, the slave sends a bit and the master reads it

The SPI bus transmits data in an 8-bit data groups, sending data one bit at a time from MSB to LSB.

An example of bit transmission for byte A and byte B would be

A(bit 7) A(bit 6) … A(bit 0) B(bit 7) B(bit 6) … B(bit 0)

3.2. Clock Polarity and Phase

The clock polarity and phase can be configured with respect to the data. The serial clock input

frequency can go up to 400k bps.

1.2 .

When clock polarity =0 the base value of the clock is 0

1.2.1.

For clock phase=0, data are read on the clock's rising edge (low->high transition) and data

are changed on a falling edge (high->low transition).

1.2.2.

For clock phase=1, data are read on the clock's falling edge and data are changed on a

rising edge.

1.3 .

When clock polarity=1 the base value of the clock is 1

1.3.1.

For clock phase=0, data are read on clock's falling edge and data are changed on a rising

edge.

1.3.2.

For clock phase=1, data are read on clock's rising edge and data are changed on a falling

edge.

The signal is required to read card data from the device. See SPI clock phase and polarity property in

section 3 for commands to configure clock phase and polarity.The device defaults to clock phase = 0

and clock polarity = 0

The following picture shows an example of clock polarity=0 and clock phase=0. The data is read on

the rising edge of the clock and is changed on the falling edge. On MOSI line, the host sends out data

00000010, which is 02h.

3.3. Master Input, Slave Output (MISO)

The MISO signal is the serial data output sent from for the device, it’s also the data line that is received

by the host. When the device is not active (Chip Select is high), the MISO becomes high impedance

(disconnected). The MISO signal would be in an indeterminate state after the device is power cycled or

reset for a maximum of 1 second. This signal should be ignored during this time.

3.4. Master Output, Slave Input (MOSI)

The MOSI signal is the serial data input for the device and serial data output for the host. This signal is

sent from the host (master) to the device (slave). The signal might not be required once some device

parameters such as the device key has been set and saved. Set the signal to be high if it is not being

used.
