Description

The EPCQ256SI16N is a configuration PROM (Programmable Read-Only Memory) for FPGAs (Field-Programmable Gate Arrays). It is a non-volatile memory that allows for the serial or quad-serial configuration of devices that support active serial (AS) x1 or AS x4 configuration schemes. This component is available in 8- and 16-pin small-outline integrated circuit (SOIC) packages and operates between 2.7V and 3.6V.

Specifications and Features

The EPCQ256SI16N boasts the following specifications and features:

• Non-volatile memory
• Low cost
• Low pin count
• More than 100,000 erase or program cycles
• Write protection support for memory sectors using status register bits
• Fast read, extended dual input fast read, and extended quad input fast read of the entire memory using a single operation code
• Write bytes, extended dual input fast write bytes, and extended quad input fast write bytes of the entire memory using a single operation code
• Reprogrammable with an external microprocessor using the SRunner software driver
• In-system programming (ISP) support with the SRunner software driver
• ISP support with USB-Blaster™, EthernetBlaster II, or EthernetBlaster download cables

Application Scenarios

The EPCQ256SI16N is commonly used in FPGA applications that require serial or quad-serial configuration schemes. It is often used in industries such as aerospace, automotive, and industrial automation.
