Canaan Technology Launches New Avalon A13 Series Bitcoin Miners

Canaan Technology Launches New Avalon A13 Series Bitcoin Miners According to the latest news, Canaan Technology announced the launch of the new Bitcoin miner Avalon Made A13 series, including Avalon A1346 and Avalon A1366. Canaan Technology said that the new generation of miners uses advanced ASIC technology, and the A13 series will include two different models. Compared with the 90 to 100TH/s hash rate offered by the A12 series, the A13 series has both hash rate, and energy efficiency has been enhanced. Canaan's CEO said the all-new A13 is a milestone in the company's over-computational energy consumption analysis. The model A1346 has a hash rate of 110 TH/s and an energy efficiency of 30J/TH. Model A1366 has a hash rate of 130TH/s and an energy efficiency of 25J/TH. Comparing the energy efficiency ratio of Bitmain's flagship S19 XP of 21.5 J/TH with that of Bitmain's M50S of 0.026j/Gh, the new series of A1346 is "very competitive" in terms of efficiency at

Easily damaged parts of Antminer S17 hash board introduction

After counting, I found more than ten different chips on the S17 hash board, which roughly include ASIC chips, temperature sensor chips, MOS chips, voltage regulator chips, converter chips, etc. So, where exactly are they on the hash board? Let's find out together!

Easily damaged parts of Antminer S17 hash board introduction:

BM1397AD ASIC chip

BM1397AD ASIC chip
The Antminer S17 hash board has 48 built-in BM1397AD ASIC chips, which are located under the heat sink and fixed with thermal adhesive, mainly used for the calculation of the hash rate of the miner.

CT1F

CT1F converter chip location
SN74LVC1T45DBVR CT1F is a 6-pin dual-power bus transceiver chip IC using SOT23-6 packaging technology; the operating temperature is between -40℃~+80℃, and the working voltage is between 1.65V~5.5V.

AP431SAN1TR-G1 GCC:

GCC adjustable shunt regulator location
The AP431SAN1TR-G1 is a 3-terminal adjustable shunt regulator. Available in SOT23 package technology, with its sharp turn-on characteristics, the AP431SAN1TR has a low minimum cathode current for regulation, and a typical value of 50µA, making the device ideal for very low power applications.

U165: T451

T451 temperature sensor chip
The S17 hash board has 4 built-in T451 temperature sensor chips located around the hash board. The chips use WSON-8 packaging technology to sense the temperature of the hash board when it is running. If the temperature sensor chip is damaged, it will cause abnormal temperature readings. Likewise, if the temperature sensor chip temperature is too low, the hash board will not start, or if the temperature is too high, the miner will stop running.

Q8: P34M4SS

MOS chip DMP34M4SPS
The MOS DMP34M4SPS-13 is an enhancement mode MOS 30V 21A P-channel designed to minimize RDS(ON) and maintain excellent switching performance; the chip has high conversion efficiency and is mainly suitable for power management and load switching.

U7: MPSK301517DR377900

MPSK391517DR boost converter chip
The MPSK391517DR chip is a 3A, 25V, 1.1MHz boost converter chip. Packaged in a tiny 4mm*4mm 16-pin QFN package technology, it regulates the output voltage to 25V with up to 95% efficiency and operates over a temperature range of –40°C to +85°C.

U252: SXE1923

SXE1923 voltage monitoring chip
The SXE1923 voltage monitoring chip is mainly used to monitor the real-time voltage of the hash board voltage domain. This component is on the back of the boost circuit. When damaged, the front booster chip will not be able to receive the returned data and stop working, causing the hash board to fail to start. In addition, the hash board is susceptible to electromagnetic interference from adjacent hash boards, which affects the 25Mhz clock signal, resulting in unstable operation, inaccurate temperature monitoring, repeated startup, and other failures.

U3: dsPIC33EP16

dsPIC33EP16 microcontroller chip
dsPIC33EP16 GS202 is a hash board 16-bit microcontroller chip in the SOIC-28 package specification, which is used to store Hashboard's configuration data (ie, PIC file). After the chip is damaged, the hash board does not work, and the voltage and resistance of the whole board are normal, but it cannot start normally.

U6: ATH81402DMCN

EEPROM chip
The AT24C002D provides 2,048-bit serial electrically erasable and programmable read-only memory (EEPROM) in an 8-pin TSSOP package. The operating voltage is between 1.7V and 3.6V.

U170: MP2019JC859121MPSK25

MP2019 linear regulator chip
MP2019JC859121MPSK25 is the product number of the MP2019 series of linear regulators; it comes in the SOP8 package and is suitable for hash board maintenance. It has a voltage input range of 3V to 40V and a current rating of 300mA.

U228: CADMLF

CADMLF voltage domain control chip
CADMIZ is a hash board voltage domain control chip whose operating input voltage range between 1.7V to 5.5V; using UDFN 1×1mm packaging technology, it supports low input and output voltage requirements, robustly designed and reliable high applications.

U156: SQ7JL SGM2036-ADJ

SGM2036-ADJ linear regulator chip
The SGM2036-ADJ is a 300mA, low power, low dropout, RF linear regulator in an OT-23-5 package with an input voltage between 1.6V and 5.5V; there are functions such as short-circuit automatic discharge and high output voltage progress, which can prolong the life of the battery.
