[Altera Corporation]

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)

– 20-pin plastic J-lead chip carrier (PLCC) package

– 32-pin plastic thin quad flat pack (TQFP) package

– 100-pin plastic thin quad flat pack (TQPF) package

– 88-pin Ultra FineLine BGATM package

■ EPC2 device has reprogrammable Flash configuration memory

– 5.0-V and 3.3-V in-system programmability (ISP) through the

built-in IEEE Std. 1149.1 Joint Test Action Group (JTAG)

interface

– Built-in JTAG boundary-scan test (BST) circuitry compliant with

IEEE Std. 1149.1

– ISP circuitry is compatible with IEEE Std. 1532 for EPC2

configuration device

– Supports programming through Serial Vector Format Files

(.svf), JamTM Standard Test and Programming Language

(STAPL) Files (.jam), Jam STAPL Byte-Code Files (.jbc), and the

MAX+PLUS II software via the MasterBlasterTM,

ByteBlasterMVTM, or BitBlasterTM download cable

– nINIT_CONF pin allows a JTAG instruction to initiate device configuration

– Can be programmed with Programmer Object Files (.pof) for EPC1 and EPC1441 devices

– Available in 20-pin PLCC and 32-pin TQFP packages

■ EPC4, EPC8, and EPC16 configuration devices have reprogrammable

Flash configuration memory with density up to 16,000,000 or

32,000,000 bits with compression feature in these devices.
