Espressif has updated the ordering codes to distinguish between them. 3. 变更描述/ Description of Change 段落 1 中 ESP32-H2 系列产品的芯片硬件金属层变更，芯片版本将由 v0.1 升级为 v1.2，最新的 ESP32-H2 版本 v1.2 与需求版本的 ESP-IDF 搭载使用，可优化产品安全等性能。ESP32-H2 v1.2 新功能及功能优化信息可参见附录 I。段落 1 中列出的模组和开发板产品中使用的主芯片为 ESP32-H2 芯片，因此也进行相应变更。 The ESP32-H2 chip revision v1.2 involves a metal layer change to the chip revision v0.1, providing enhanced security performance when used with the required ESP-IDF version. For the new features and improvements in chip revision v1.2, please refer to Appendix I. Modules and development boards listed in Para 1 are based on ESP32-H2 series of chips and thus will change accordingly. 4. 变更对比/ Change Comparison 请见附录 I：变更对比。 Please refer to Appendix I: Change Comparison. www.espressif.com Page 3 / 8 识别方式/ Identification Method: 芯片产品：通过产品型号，eFuse 及产品丝印。 模组和开发板产品：通过产品型号，主芯片的 eFuse，模 组 屏 蔽 盖 丝 印 的 产 品 规 格 标 识 位 ，或 产 品 外 箱 标 签 中的 PW 号。 Chip products: Identified by part number, eFuse bits and chip marking. Module and Development Board products: Identified by the part number, chip eFuse, specification identifier on the module shield marking, or PW No. on carton box. 5. 变更影响/ Impact of Change 1) 品质和性能/ Quality & Performance: ESP32-H2 芯片版本 v1.2 必须搭配指定版本的 ESP-IDF 使用，具体 ESP-IDF 版本请参见下面段落 5-5）中 的 表 格 “ESP32-H2 v1.2 所需 ESP-IDF 版本”。使 用 需求版本的 ESP-IDF 可正常使用 ESP32-H2 v1.2 系列产品并可应用 ESP32-H2 v1.2 所提供的新的功能及获得功能优化，ESP32-H2 v1.2 新功能及功能优化信息可参见附录 I。 The ESP32-H2 chip revision v1.2 must be used with a specified version of ESP-IDF. For details, refer to Table Required ESP-IDF Version for ESP32-H2 v1.2 in Para 5-5) below. With the required ESP-IDF version, you can use the new features and the improved existing features in chip revision v1.2, see Appendix I > New Features and Improvements. 2) 交期/Delivery: 对于变更后的新版本，乐鑫将保持产品标准交货周期（Standard Lead Time）不变。 对于变更前的旧版本，乐鑫未来无供应计划；若您有订单需求，请务必尽快联系乐鑫商务人员。 为保障供应，请您及时确认版本变更并完成软件升级。 The upgraded products will maintain the standard lead time. For products with ESP32-H2 chips prior to revision v1.2, Espressif has no future supply plans. If you have order requirements, please contact Espressif's sales team as soon as possible. To ensure the smooth delivery of future orders, customers are advised to promptly complete software upgrades and verify the updated product. 3) 订购代码/ Ordering Code: 芯片，模组和开发板产品：请使用新的订购代码下单，变更后订购代码参见段落 1。 www.espressif.com Page 4 / 8 Chips, modules, and development boards: Please place orders using the new ordering code. Refer to Para 1 for the updated ordering code. 4) 认证/ Certification: 不影响/ No impact 5）软件/ Software: 随着 ESP32-H2 系列升级为 v1.2 版本芯片，如果您当前使用的是早于 v1.2 的芯片版本，则现有的 ESP-IDF 版本可能无法兼容 v1.2 芯片。为确保兼容性，请将 ESP-IDF 升级至需求版本或更高版本（参见下表“ESP32-H2 v1.2 所需 ESP-IDF 版本”）。 将 ESP-IDF 升级至需求版本或更高版本后，请保持 Kconfig 中 ` ESP32H2_REV_MIN` 的配置不变，然后重新编译二进制文件。编译后的二进制文件可在之前的芯片版本以及 v1.2 上运行。如已使用上述 ESP-IDF 需求版本或更高版本编译了二进制文件，则无需再更新软件。 As the ESP32-H2 chip series upgrades to the v1.2 chip revision, if you are using a pre-v1.2 chip version, your existing ESP-IDF version may not be compatible with the v1.2 chip. To ensure compatibility and to have the same binary supporting ESP32-H2 v1.2 and the older version of the chip you are using, please make sure the binary is built with ESP-IDF version equal to or higher than the required version (see Table Required ESP-IDF Version for ESP32-H2 v1.2). If not, please upgrade ESP-IDF to the required version or higher and rebuild your binary with Kconfig option ` ESP32H2_REV_MIN` unchanged. The built binary is able to run on all existing chips and on ESP32-H2 v1.2 as well. If your binary is already built with these versions, there is no need to upgrade your software.
