6/(( 6KRUW3URGXFW,QIRUPDWLRQ 6 / 7 *HQHUDO’HVFULSWLRQ SLE 5536/36E is designed for applications in prepaid telephone cards. The chip consists of an EEPROM memory of 221 bit, a ROM of 16 bits, a control/security unit and a special computing unit for chip authentication. The shaded blocks in the block diagram (Figure 3) contain the enhanced features of SLE 5536/36E compared to SLE 4406/06E. &RQWURO8QLW 6HFXULW\\,QWHUIDFH &/. ,2 9&&*1’567 $GGUHVV 8QLW $XWKHQWLFDWLRQ 8QLW 3URJUDPPLQJ8QLW 0HPRU\\8QLW Counter Identification Area Data Areas 16 bit Manufacturer Code 8 bit Manufacturer Data 40 bit blockable PROM Authenti- cation Key 1 6/( 6/(( Identification Area 16 bit Manufacturer Code 48 bit blockable PROM /HJHQG Shaded blocks - Enhanced features of SLE 5536/36E compared to SLE 4406/06E Blocks marked by cross hatch - Defined by chip manufacturer optional Authenti- cation Key 2 Backup Unit )LJXUH %ORFN’LDJUDP
