Functional Description

With SRAM-based devices, configuration data must be reloaded each time the system initializes, or when new configuration data is needed. Altera configuration devices store configuration data for SRAM-based APEX II, APEX 20K, Mercury, ACEX, and FLEX devices. Table 1 lists Altera configuration devices.

Features

■ Serial device family for configuring APEXTM II, APEX 20K (including
APEX 20K, APEX 20KC, and APEX 20KE), MercuryTM, ACEX® 1K,
and FLEX® (FLEX 6000, FLEX 10KE, and FLEX 10KA) devices
■ Easy-to-use 4-pin interface to APEX II, APEX 20K, Mercury, ACEX,
and FLEX devices
■ Low current during configuration and near-zero standby current
■ 5.0-V and 3.3-V operation
■ Software design support with the Altera® Quartus® II and
MAX+PLUS® II development systems for Windows-based PCs as
well as Sun SPARCstation, and HP 9000 Series 700/800
■ Programming support with Altera’s Master Programming Unit
(MPU) and programming hardware from Data I/O,
BP Microsystems, and other manufacturers
■ Available in compact plastic packages (see Figures 1 and 2)
– 8-pin plastic dual in-line package (PDIP)
