ATECC608A-MAHDA-T 产品概述

一、产品简介

ATECC608A-MAHDA-T是Microchip出品的高安全认证芯片,封装为UDFN-8-EP(2x3),适用于空间受限且对安全性要求高的终端设备。器件提供硬件级密码运算与密钥存储,用以实现设备身份认证、固件完整性校验、加密通信等安全功能,满足物联网及嵌入式系统的可信根需求。

二、核心特性

  • 工作温度:-40℃ ~ +85℃,适应工业级环境。
  • 工作电压:2.0V ~ 5.5V,兼容单节锂电及多种微控制器供电域。
  • 待机电流极低:约150 nA,适合低功耗和电池供电场景。
  • 加密算法:硬件支持 AES-128、SHA-256 和椭圆曲线密码(ECC,支持 NIST P‑256),并内置真随机数发生器(TRNG)。
  • 接口类型:标准 I2C 接口,便于与主控MCU集成。
  • 物理封装:UDFN-8-EP (2x3),焊盘设计利于自动贴装与热散。

三、安全功能亮点

  • 私钥硬隔离存储,非导出设计,降低密钥泄露风险。
  • 支持硬件加速的 ECDSA/ECDH 运算,可用于证书签名、密钥协商与安全引导。
  • 支持 SHA-256 散列与 HMAC,用于数据完整性与认证。
  • 内置可配置的访问控制与保护机制,支持防篡改与抗重放策略。
  • 提供可编程的密钥/签名/计数器管理接口,便于实现防重放和计量机制。

四、典型应用场景

  • 物联网终端设备的设备唯一身份与安全上链。
  • 安全引导与固件签名验证,防止恶意固件注入。
  • TLS/DTLS 或 MQTT 等协议的凭证与私钥管理,减轻主控计算负担。
  • 可穿戴设备、智能家居、工业控制与边缘网关等需低功耗安全存储的场景。

五、设计与集成建议

  • 推荐将器件靠近主控I2C总线并设计合适的电源去耦,以保证通信与时序稳定。
  • 在 PCB 布局时预留热焊盘(EP)便于散热与焊接质量控制。
  • 利用芯片提供的密钥管理与访问控制策略,设计分级安全策略(例如区分引导验证与运行时认证)。
  • 在量产阶段结合生产安全流程进行密钥注入与认证,以保证供应链端到端可信。

Electronic component sourcing availability dashboard with ESD-protected samples

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
