Smart card interface in a compact 28-TSSOP
The ST8024CTR is an STMicroelectronics interface IC purpose-built for smart card reader and writer applications, handling the electrical-level translation and sequencing between a host controller and a smart card slot.
Peer cross-reference: ST8024CDR
The closest functional sibling is the ST8024CDR, which shares the same smart card interface function, 2.7 V supply range, and surface-mount package — the difference is the package type (ST8024CDR is also a 28-TSSOP variant, but with different order-code suffix). Both are active and ROHS3 compliant.
