TriMag IV Chip

PCI SRED Triple-Track Decoding ASIC
with Micro Processor and Encryption Engine


Three Track Decoding in a Small Footprint
TriMag IV is ID TECH’s MSR decoding ASIC that is 5mm x 5mm, 36-pin component. It integrates MSR functions with the triple DES encryption engine, physical security protection hardware, and UART/SPI interface. Upon receipt of the magnetic head signals, the card data is recovered, encrypted, and transferred to the external interfaces via UART or SPI interface. The chip supports up to 3 tracks of card reading at the same time. Signal processing techniques are employed to recover F2F encoded MSR data reliably from head signals with severe fluctuation of signal amplitude, widely varying bit interval, and jittery bit position.
