EPCS16集成电路（IC）的用于FPGA的配置PROM规格书PDF中文资料

Functional 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.

特性 Features

The serial configuration devices provide the following features:

■ 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

■ In-system programming support with USB Blaster™, EthernetBlaster, or ByteBlaster™ II download cables

■ Additional programming support with the Altera® Programming Unit (APU) and programming hardware from BP Microsystems, System General, and other vendors

■ Delivered with the memory array erased (all the bits set to 1)
