| Single
Track Asic for Magnetic Stripes |
This
MagChip™ Application-Specific Integrated Chip
(ASIC) is for reading and decoding a single track on a
magnetic stripe. Because MagChip is an Integrated Circuit (IC)
designed specifically to perform reading and decoding functions,
it is smaller, consumes less power, and costs less than a generalpurpose
processor chip while delivering superior performance.
MagChip decodes the analog output from a magnetic “read”
head
and produces a digital data-bit stream with clock and “media
detect” outputs.
• Low power—sleeps when not reading
• Less than 1.0mA typical when reading a card
• Less than 30µA when in “sleep” mode
(15µA typical)
• Operation from 2.7V to 5.5V
• True AGC handles signal amplitudes from 1mV to 1V p-p
• Excellent data jitter, media glitch, and drop-out immunity
• ±2000V Electro-Static Discharge (ESD) protection
• Typical card swipe speeds from 7.5 to 200+ cm/sec (3
to 80+ IPS)
• Provided in a plastic, industry standard SOIC-8 surface
mount package
• Only two external capacitors recommended
• Compatible with a wide range of available read heads
• Supports bi-directional card swiping and decoding |
