EPCQ16ASI8N is a configuration memory series developed by Cypress, a leading provider of memory products. This series is found to be useful in system-on-chip (SoC) designs, including applications requiring low emissions, faster boot and program times and high reliability. It is especially suited for microcontroller based designs, Field Programmable Gate Arrays (FPGAs) and other logic devices.

Types of EPCQ16ASI8N

The EPCQ16ASI8N series offers two types of parallel configuration PROMs that are designed to configure the FPGAs. The first type is the Serial Flash memory. This is a type of non-volatile memory that stores data in an array of floating gate transistors even after the power is turned off. The second type is the In-System Programming (ISP) PROM. This is a non-volatile memory device that can be programmed to a specific configuration via an external programming device.

Features

Apart from these two types, the EPCQ16ASI8N series features two other features that make it a suitable choice for configuring FPGAs. First, the series provides a maximum read access time of 70 nanoseconds which is quite fast compared to other Flash memory products. Secondly, the devices are designed for enhanced environmental operation, meaning that they are able to operate in temperatures ranging from -40°C to +100°C as well as higher shock and vibration levels.

Application Field and Working Principle

One of the main application fields for EPCQ16ASI8N is the FPGA configuration. This series is a cost-effective alternative to conventional Flash memory products and provides the necessary features to support efficient FPGA configuration. The EPCQ16ASI8N works as follows. During power-up, the FPGA device itself looks for its configuration data. When it finds the required data, it is programmed. This process is known as configuration data loading. Since the EPCQ16ASI8N is a non-volatile memory device, it is able to retain its stored data even after the power is turned off.

Benefits

EPCQ16ASI8N provides many benefits over other memory products for FPGA configuration. First, its fast read access time of 70 nanoseconds offers a quicker boot time for applications. Additionally, the In-System Programming (ISP) PROM available in the series can be programmed directly from the FPGA, thus eliminating the need for an external programming device. Finally, the series is designed for enhanced environmental conditions and thus reliable in a wide range of environmental conditions such as humidity and vibration.

Conclusion

In conclusion, EPCQ16ASI8N is a configuration memory series developed by Cypress and is suitable for applications requiring faster boot and programming times, as well as enhanced environmental operation. This series features two types of parallel configuration PROMs, Serial Flash memory and In-System Programming (ISP) PROM, that are used to configure the FPGAs. Additionally, the EPCQ16ASI8N series offers a maximum read access time of 70 nanoseconds, further enhancing the boot time of applications, and can be programmed directly from the FPGA, eliminating the need for an external programming device.
