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 V9 hash board

Today, let's look at the detailed report of the Antminer V9 hash board, which includes the types, locations, and functions of all chips on the V9 hash board.

Easily damaged parts of Antminer V9 hash board:

BM1580 ASIC chip

Below the dense heat sink are the ASIC chips of the V9 hash board; each of the hash boards carries 45 BM1580 ASIC chips. Connected to the heat sink by thermosetting adhesive, they are mainly responsible for the hash rate calculation of the V9 miner.

U1: 27402S

synchronous buck controller chip
LM27402S is a new original high-performance synchronous buck controller with DCR current sensing function, mainly used to maintain hash boards. A 0.6V±1% voltage reference enables high accuracy and low voltage capability at the output. In addition, the 3V to 20V input operating voltage range makes the LM27402S suitable for many input rails.

Q3: TPHR9003NL

MOS chip TPHR9003NL
The MOS chip TPHR9003NL is mainly used to check the voltage output in the voltage domain. By measuring the output of the power supply terminal of the hash board, it can judge whether the MOS is short-circuited. Under normal circumstances, the voltage is unstable, and the lightning surge will cause damage to the MOS.

U111: 37501739

boost converter chip
The SGM3750 is a 650kHz boost converter for driving series LEDs. The chip integrates LED open circuit protection, preventing the chip from being damaged due to overvoltage under LED open circuit conditions. It is packaged in a green TDFN-2×2-6L technology, with an operating temperature range of -40°C to +85°C and an operating voltage between 2.7V and 20V.

U64: 4VK4

voltage regulator chip
LN1134A182MR-G 4VK4 is a high-speed, low-dropout, high-precision output voltage, low-current-consumption positive voltage regulator developed using CMOS technology. The chip has a built-in low on-state resistance transistor, its output voltage is between 1.0V and 5.0V, and the maximum output current is 300mA.

L3: PIC16F1704

microcontroller chip
The PIC16F1704 is an 8-bit microcontroller processor that combines intelligent analog integration with low cost and shallow power consumption, mainly used to maintain hash boards. The operating temperature of the chip is between -40°C and 85°C.

U100: TMP757CK

TMP75 temperature sensor chip
TMP757CK is the product number of the miniature temperature sensor chip TMP75 series, in small 8-pin MSOP and 8-pin SOIC packages, mainly used for sensing hash board temperature; it can be accurate to -1°C (typ), -40° C to +125°C ambient temperature, it is suitable for Antminer S9, T9+, S9se, S11, S15, V9, and other hash boards.

U70: DD7R

CMOS LDO regulator chip
The BL9198 DD7R is a CMOS LDO regulator designed for portable RF and wireless applications with demanding performance and space requirements. Performance is optimized for battery-powered systems, delivering ultra-low noise and low quiescent current. The device consumes less than 0.01µA in shutdown and has a fast turn-on time of less than 50µs.
