4. Serial Configuration Devices (EPCS1,

EPCS4, EPCS16, EPCS64, and EPCS128)

Data Sheet

Introduction

The serial configuration devices provide the following features:

■ 1-, 4-, 16-, 64-, and 128-Mbit flash memory devices that serially configure Stratix

III, Stratix II GX, and Stratix II FPGAs, Arria

™

GX FPGAs, and the Cyclone

series

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 and EPCS128 available in 8-pin or 16-pin small outline

integrated circuit (SOIC) packages

■ 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

™

, Ethernet Blaster

™

, 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

■ Software design support with the Altera Quartus

II development system for

Windows-based PCs as well as Sun SPARC station and HP 9000 Series 700/800

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

1 The term “serial configuration devices” used in this document refers to Altera EPCS1,

EPCS4, EPCS16, EPCS64, and EPCS128.

Functional Description

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 4–1 lists the serial configuration devices.

For an 8-pin SOIC package, you can migrate vertically from the EPCS1 to the EPCS4

or EPCS16 since 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.

1 EPCS16 is available in 8-pin and 16-pin SOIC packages.

Table 4–2 lists the serial configuration device used with each Stratix IV FPGA and the

configuration file size. For lager Stratix IV devices such as EPC4SGX290 and

EP4SGX360.
