SAG NEWS - TAICHUNG, December 14, 2009
EM4200, evolving from its predecessor EM4102, remains MEGA PADS on it as the greatest feature. SAG makes a good use of this by the patented 「direct bonding technology」 and brings out the ultra flat card surface which wins the confidence from those who are involved in personalization card business.
The so-called direct bonding technology is the direct combination between IC and copper coil through the help of MEGA PADS. Such structure, unlike PCB which is adopted by most card suppliers, reduces the chance for bumped surface. As a result, SAG EM4200 direct bonding ISO card is superior to those with PCB module inside when it comes to quality printing and reliability. SAG can be your answer to quality card printing.
*EM4200, 64bit Read Only chip released by EM Marin SA in 2009, is the successor from the family of EM4100, EM4102, and EM4105 low frequency ICs.
EM4200 DESCRIPTION
EM4200 is a CMOS integrated circuit intended for use in
electronic Read Only RF transponders. It is designed to
replace seamlessly the EM Microelectronic-Marin Read
Only ICs EM4100/4102 and EM4005/4105.
The circuit is powered by an external coil placed in an
electromagnetic field and gets its master clock from the
same field. By turning on and off the modulation current,
the chip sends back the unique code contained in a factory
pre-programmed laser ROM.
The 128 bit unique code is stored in laser programmed
ROM. Several options are available to use 64, 96 or 128
bits of ROM.
The IC offers also different resonant capacitor versions,
selectable by mask option (0pF, 75pF and 250pF) providing
the same reading performances to ensure seamless
replacement. |
