Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The Intel EPCQ4ASI8N is a 4MB capacity serial configuration memory belonging to the EPCQ-A series of products, primarily used for configuration storage in FPGAs (Field-Programmable Gate Arrays) and CPLDs (Complex Programmable Logic Devices). The device is housed in an 8-pin SOIC package (3.90mm wide) and supports in-system programming (ISP) functionality. It operates within a voltage range of 2.7V to 3.6V and is designed to function reliably within the industrial temperature range of -40°C to 85°C.

EPCQ4ASI8N Core Features

High-speed serial interface and storage performance:

Supports a four-wire SPI (Quad SPI) interface with a maximum clock frequency of up to 100MHz

4Mbit (512K × 8) storage capacity, meeting the configuration requirements of most FPGAs

Synchronous operating mode with high data transfer rates, enabling rapid loading of FPGA configuration data

Reliable storage characteristics:

Supports block programming and electrical erasure functionality, enhancing flash memory write efficiency

Data retention time of at least 20 years, with durability of 100,000 erase/write cycles

Utilises EEPROM technology, supporting electrical erasure and reprogramming

Low Power Consumption and High Integration Design:

Extremely low operating current, with a maximum standby current of only 0.00005A

8-pin SOIC small package, saving PCB space

Compliant with RoHS standards, environmentally friendly design

• 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.
