Serial Configuration Devices
Description:
With SRAM-based devices that support active serial configuration, configuration data must be reloaded each time the device powers up, the system reconfigures, or when new configuration data is required. Serial configuration devices are flash memory devices with a serial interface that can store configuration data for FPGA devices that support active serial configuration and reload the data to the device upon power-up or reconfiguration. Table 3–1 summarizes the features of the Altera configuration devices and the amount of configuration space they hold.
For an 8-pin SOIC package, you can migrate vertically from the EPCS1 to the EPCS4 or EPCS16 because the EPCS devices are offered in the same device package. Similarly, for a 16-pin SOIC package, you can migrate vertically from the EPCS16 to the EPCS64 or EPCS128.
Applications:
1-, 4-, 16-, 64-, and 128-Mbit flash memory devices that serially configure
Arria® series, Cyclone® series, all device families in the Stratix® series except the Stratix device family, and FPGAs using the active serial (AS) configuration scheme
Easy-to-use four-pin interface
Low cost, low-pin count, and non-volatile memory
Low current during configuration and near-zero standby mode current
2.7-V to 3.6-V operation
EPCS1 and EPCS4 available in 8-pin small outline integrated circuit (SOIC) package. EPCS16 available in 8-pin or 16-pin SOIC packages. EPCS64 and EPCS128 available in 16-pin SOIC package
Enables the Nios® processor to access unused flash memory through AS memory interface
Re-programmable memory with more than 100,000 erase/program cycles
Write protection support for memory sectors using status register bits
In-system programming support with SRunner software driver
