Tropic Square TROPIC01A Security Chip QFN32

Product detailed description

TROPIC01A is a transparent and auditable secure element developed by the Czech company Tropic Square. It is designed for applications that require a high level of security, trusted key storage, encrypted communication, digital signatures and cryptographic operations with an emphasis on openness and cryptographic auditability. The chip comes in a compact QFN32 4×4 mm package and can be easily integrated into your own PCB.
