产品概述

描述

STSAFE-TPM（可信平台模块）产品系列为嵌入式、PC、移动和计算应用等设备提供广泛的标准化解决方案产品组合。STSAFE是意法半导体的商标。

它包含符合可信计算组织(TCG)标准的交钥匙产品，可提供服务来保护信息和设备的保密性、完整性和真实性。

借助各种支持的接口和可用的TPM生态系统软件解决方案，使这些设备易于集成。

STSAFE-TPM芯片均通过了通用标准(Common Criteria EAL4+)和FIPS认证。

它们嵌入了具有额外安全特性的Arm® SecurCore® SC300™处理器，可帮助抵御先进形式的攻击。

ST33TPHF2XI2C提供I²C接口，并兼容TCG PC Client规范的TPM配置文件。

它在TPM固件升级过程中提供弹性服务，并能在检测到故障时自动恢复TPM固件与关键数据。

ST33TPHF2XI2C在1.8 V工作时，能够在–25至+85 °C的商业级温度范围内运行; 或在3.3 V工作时，能够在–40 °C至105 °C的扩展温度范围内运行。

该器件以VFQFPN32 ECOPACK2封装提供。ECOPACK是意法半导体的商标。
