Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

SE98ATP is a digital temperature sensor designed by NXP for DDR2/DDR3/DDR4 memory modules compliant with the JEDEC-JC42.4 standard. It features an 8-pin HWSON package (2 mm × 3 mm) and is directly soldered onto the DIMM board to monitor the temperature of DRAM chips in real time, providing data for system thermal management, fan speed control, safe underclocking, or emergency shutdown.

SE98ATP Features

• Complies with JEDEC Class B specifications: typical error of ±0.5 °C in the 75 °C to 95 °C range, with a maximum of ±1 °C

• 11-bit ADC with a resolution of 0.125 °C and an update rate of 8 Hz

• Open-drain EVENT pin, configurable as a temperature control comparator or interrupt output, supporting three events: over-temperature, under-temperature, and critical temperature

• Shutdown current only 0.1 µA, operating current 250 µA (typical)

• I²C/SMBus interface, clock 0 Hz-400 kHz, built-in SMBus TIMEOUT anti-lockup

• Three address pins, up to 8 devices can be connected to a single bus

• ESD protection: HBM 2 kV, MM 250 V, CDM 1 kV; passed JESD78 100 mA lock test

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
