# BM1397 (Component) ## Description The Antminer BM1397 BM1397AG chip supports the SHA256 algorithm, which can be used for BTC, BCH and other encrypted digital currency mining, and will be used in the next-generation SHA256 algorithm of the new Antminer S17 and T17. BM1397 adopts global TSMC FinFET technology, a single chip integrates more than 1 billion transistors, and has been continuously optimized in terms of circuit structure and low power consumption technology. The energy efficiency ratio of BM1397 is 30J/T. The high-quality Antminer BM1397AG can replace damaged chips on S17, S17+, S17Pro, T17, T17+ hash boards. Please note that we recommend that each Hash board only replace 5 damaged chips at most. Of course, Antminer BM1397AD and Antminer BM1397AI can also replace damaged chips of S17, S17+, S17Pro, T17, T17+ hash boards. These three kinds of chips are universal and can be replaced with each other. ## Component Details - **Owner:** adrian95 - **Created:** 3/22/2025 - **Last Updated:** 3/22/2025 - **Visibility:** Public - **Manufacturer Name:** Bitmain - **License:** https://creativecommons.org/licenses/by/4.0/ - **Part Type:** Integrated Circuit - **Manufacturer Part Number:** BM1397 - **Product Info Url:** https://www.zeusbtc.com/ASIC-Miner-Repair/Parts-Tools-Details.asp?ID=230 - **Used in:** 79 projects - **Part Type:** Integrated Circuits - **Sub-Type:** Logic - **MPN:** BM1397 - **Mount Type:** Through Hole - **Pin Count:** 34 - **Logic Function:** AND ## Pins | Pin | Name | Type | |-----|------|------| | 1 | VDD3_0 | | | 2 | VDD2_0 | | | 3 | VDD1_0 | | | 4 | ADDR0 | | | 5 | ADDR1 | | | 6 | ADDR2 | | | 7 | TEST | | | 8 | CLKO | | | 9 | CO | | | 10 | RI | | | 11 | NRSTO | | | 12 | BO | | | 13 | PLL_VSS | | | 14 | PLL_VDD | | | 15 | VDDIO08_0 | | | 16 | VDDIO18_0 | | | 17 | VDDIO18_1 | | | 18 | VDDIO08_1 | | | 19 | VSS | | | 20 | PIN_MODE | | | 21 | TEMP_N | | | 22 | TEMP_P | | | 23 | RF | | | 24 | TF | | | 25 | BI | | | 26 | NRSTI | | | 27 | RO | | | 28 | CI | | | 29 | CLKI | | | 30 | VDD1_1 | | | 31 | VDD2_1 | | | 32 | VDD3_1 | | | 33 | VDD | | | 34 | VSS | | --- *Generated from [https://www.flux.ai/adrian95/bm1397](https://www.flux.ai/adrian95/bm1397)*
