To ensure a robust and diversified module supply, Espressif has qualified the upgraded flash from the same manufacturer on ESP32-S2 series of chips. Therefore, the upgraded flash will be introduced as the new alternative source for products listed in Para 1. 3. 变更描述/ Description of Change 1) 段落 1-1)中 ESP32-S2 系列产品的芯片版本将由 v0.0 升级为 v1.0。结合使用乐鑫推荐版本的软件,芯片版本为 v1.0 的 ESP32-S2 系列产品提升了 11g,11n 中高速率发射功率。同时,芯片版本为 v1.0 的 ESP32-S2 系列产品的其他性能较变更前版本的产品有提升。具体信息参见附录 I-1 中勘误表信息。段落 1 中列出的 1-1)中模组产品中使用的主芯片为 ESP32-S2FH4 芯片,因此也进行相应变更。 2) 段落 1 中的所有芯片产品内置 flash 更新,因此段落 1 对应模组产品也进行相应变更。 1) Upgrade ESP32-S2 series of chips from chip revision v0.0 to chip revision v1.0 for products listed in Para 1-1). With the recommended ESP-IDF versions, the ESP32-S2 series products based on chip revision v1.0 have improved transmit power in high rates for 11g and 11n. The ESP32-S2 series products based on chip revision v1.0 have other performance improvements. For details, please refer to Appendix I-1 for Errata Information. Related module products listed in Para 1-1) are based on ESP32-S2FH4, and thus will change accordingly. 2) Flash integrated in all chip products listed in Para 1 will be upgraded. Related module products listed in Para 1 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. 识别方式/ Identification Method: 芯片产品:通过 eFuse  及产品丝印。 模组产品:通过主芯片的 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 eFuse bits and chip marking.   www.espressif.com Page 3 / 9 Module products: Identified by the chip eFuse, 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: 结合使用乐鑫推荐版本的软件,芯片版本为 v1.0 的 ESP32-S2 系列产品相比于芯片版本为 v0.0 的产品提升了 11g,11n 中高速率发射功率, 低速率及 11b 的发射功率未做调整,对认证无直接影响。 具体射频功率参见附录 I-1 中 射频功率信息。结合使用需求版本的乐鑫软件,芯片版本为 v1.0 的 ESP32-S2 系列产品射频功率无变化。芯片版本为 v1.0 的 ESP32-S2 系列产品的其他性能较变更前版本的产品有提升。具体信息参见附录 I-1 中勘误表信息。 更新后的 flash 已经通过了物料验证测试,乐鑫确认该 flash 的品质和性能满足乐鑫的要求。 With the recommended ESP-IDF versions, the ESP32-S2 series products based on chip version v1.0 have improved transmit power in high rates for 11g and 11n. The transmit power in low rates and for 11b remains unchanged, which does not have a direct impact on certification. For details about RF transmit power, please refer to Appendix I-1 for RF Power Information. The RF transmit power of the ESP32-S2 series products based on chip version v1.0 remains unchanged as before. The ESP32-S2 series products based on chip revision v1.0 have other performance improvements. For details, please refer to Appendix I-1 for Errata Information. Updated flash has completed the qualification test. Espressif confirms it fully meets the Espressif’s requirements for quality and performance. 2) 交期/ Delivery: 无影响/No impact. 3) 生产料号/ Material Part Numbers (MPN): 段落 1 中列出芯片的产品名称不变更,客户可以继续使用原有的芯片产品名称下单; 段落 1 中列出的模组的 MPN 不变更,客户可以继续使用原有的产品 MPN 进行下单。For affected Espressif chip products listed in Para 1, there is no change to the product name.
