General Description ¡El MAX 7000 family of high-density, high-performance PLDs is based on Altera’s second-generation MAX architecture. Fabricated with advanced CMOS technology, the EEPROM-based MAX 7000 family provides 600 to 5,000 usable gates, ISP, pin-to-pin delays as fast as 5 ns, and counter speeds of up to 175.4 MHz. Features... ■ High-performance, EEPROM-based programmable logic devices (PLDs) based on second-generation MAX® architecture ■ 5.0-V in-system programmability (ISP) through the built-in IEEE Std. 1149.1 Joint Test Action Group (JTAG) interface available in MAX 7000S devices – ISP circuitry compatible with IEEE Std. 1532 ■ Includes 5.0-V MAX 7000 devices and 5.0-V ISP-based MAX 7000S devices ■ Built-in JTAG boundary-scan test (BST) circuitry in MAX 7000S devices with 128 or more macrocells ■ Complete EPLD family with logic densities ranging from 600 to 5,000 usable gates (see Tables 1 and 2) ■ 5-ns pin-to-pin logic delays with up to 175.4-MHz counter frequencies (including interconnect) ■ PCI-compliant devices available ■ Open-drain output option in MAX 7000S devices ■ Programmable macrocell flipflops with individual clear, preset, clock, and clock enable controls ■ Programmable power-saving mode for a reduction of over 50% in each macrocell ■ Configurable expander product-term distribution, allowing up to 32 product terms per macrocell ■ 44 to 208 pins available in plastic J-lead chip carrier (PLCC), ceramic pin-grid array (PGA), plastic quad flat pack (PQFP), power quad flat pack (RQFP), and 1.0-mm thin quad flat pack (TQFP) packages ■ Programmable security bit for protection of proprietary designs ■ 3.3-V or 5.0-V operation – MultiVoltTM I/O interface operation, allowing devices to interface with 3.3-V or 5.0-V devices (MultiVolt I/O operation is not available in 44-pin packages) – Pin compatible with low-voltage MAX 7000A and MAX 7000B devices ■ Enhanced features available in MAX 7000E and MAX 7000S devices – Six pin- or logic-driven output enable signals – Two global clock signals with optional inversion – Enhanced interconnect resources for improved routability – Fast input setup times provided by a dedicated path from I/O pin to macrocell registers – Programmable output slew-rate control ■ Software design support and automatic place-and-route provided by Altera’s development system for Windows-based PCs and Sun SPARCstation, and HP 9000 Series 700/800 workstations ■ Additional design entry and simulation support provided by EDIF 2 0 0 and 3 0 0 netlist files, library of parameterized modules (LPM), Verilog HDL, VHDL, and other interfaces to popular EDA tools from manufacturers such as Cadence, Exemplar Logic, Mentor Graphics, OrCAD, Synopsys, and VeriBest ■ Programming support – Altera’s Master Programming Unit (MPU) and programming hardware from third-party manufacturers program all MAX 7000 devices – ¡El BitBlasterTM serial download cable, ByteBlasterMVTM parallel port download cable, and MasterBlasterTM serial/universal serial bus (USB) download cable program MAX 7000S devices
