9 / 14 page SLE 4432 SLE 4442 SLE 4440 SLE 4441 Semiconductor Group 9 Data Sheet Extension 09.98 2.2. Extended Coding Scheme Due to the available memory space the coding principle according to ISO/IEC 7816-4 applies for SLE 4432, SLE 4442, SLE 4440 and SLE 4441. Data are coded according to the ASN 1 data objects basic encoding rules using the structure Tag - Length - Value (BER TLV).
