Magnetic Card Reader | Cypress Semiconductor
Magnetic Card Readers (also known as Magnetic Stripe Readers or MSRs) read data from a 3-track magnetic stripe via a peak detection circuit and process that data for downstream users. After extracting data from the magnetic stripe, it is converted to binary data and formatted for encryption.
PSoC 3 and PSoC 5 allow a scalable solution that enables 3-channel peak detection, data conversion and formatting, and encryption on a single chip. Integration into a single chip allows small form factor designs that can be put into the reader head assembly to improve security. PSoC's scalability also allows for optional capsense button pads and/or LCD displays.
AN57821 introduces basic PCB layout practices to achieve 12- to 20-bit performance for the PSoC 3, PSoC 4, and PSoC 5LP family of devices.
AN58304 provides an overview of the analog routing matrix in PSoC® 3 and PSoC 5LP.
AN58827 discusses how internal trace and switch resistance can affect the performance of a design and how these issues can be avoided by understanding a few basic details about the PSoC® 3 and PSoC 5LP internal analog architecture.
This application note describes several techniques for implementing a peak detector in PSoC 3 and PSoC 5LP.
AN60594 describes how to create a frequency shift keying (FSK) modulator and demodulator with PSoC® 3 or PSoC 5LP, with digital 0s represented by 2100 Hz, and digital 1s, represented by 1300 Hz.
This application note describes how to configure the direct memory access (DMA) to buffer the analog-to-digital converter (ADC) data. It discusses how to overcome some of the limitations of the DMA when buffering the ADC data.
AN86233 shows how to use the PSoC 4 low-power modes and features to operate at very low power levels while retaining essential functionality. Major topics include the five power modes, PSoC Creator power management functions, and other power saving techniques and considerations. Three PSoC Creator example projects are included to demonstrate different aspects of low-power programming.
The CY8CKIT-001 PSoC® Development Kit (DVK) provides a common development platform where you can prototype and evaluate different solutions using any one of the PSoC 1, PSoC 3, PSoC 4, or PSoC 5 architectures.
