MAX 7000B devices are high-density, high-performance devices based on Altera’s second-generation MAX architecture. Fabricated with advanced CMOS technology, the EEPROM-based MAX 7000B devices operate with a 2.5-V supply voltage and provide 600 to 10,000 usable gates, ISP,  pin-to-pin delays as fast as 3.5 ns, and counter speeds up to 285.7 MHz.  EPM7256BFI256-7N Altera IC MAX 7000B CPLD 256 FBGA256 ,The MAX 7000B architecture supports 100% TTL emulation and highdensity integration of SSI, MSI, and LSI logic functions. It easily integrates multiple devices ranging from PALs, GALs, and 22V10s to MACH and pLSI devices. MAX 7000B devices are available in a wide range of packages, including PLCC, BGA, FineLine BGA, 0.8-mm Ultra FineLine BGA, PQFP, TQFP, and VTQFP packages.  EPM7256BFI256-7N Altera IC MAX 7000B CPLD 256 FBGA256 MAX 7000B devices use CMOS EEPROM cells to implement logic functions. The user-configurable MAX 7000B architecture accommodates a variety of independent combinatorial and sequential logic functions.The devices can be reprogrammed for quick and efficient iterations during design development and debug cycles, and can be programmed and erased up to 100 times.EPM7256BFI256-7N Altera IC MAX 7000B CPLD 256 FBGA256 MAX 7000B devices provide programmable speed/power optimization. Speed-critical portions of a design can run at high speed/full power, while the remaining portions run at reduced speed/low power. This speed/power optimization feature enables the designer to configure one or more macrocells to operate up to 50% lower power while adding only a nominal timing delay.  EPM7256BFI256-7N Altera IC MAX 7000B CPLD 256 FBGA256. MAX 7000B devices also provide an option that reduces the slew rate of the output buffers, minimizing noise transients when non-speed-critical signals are switching. The output drivers of all MAX 7000B devices can be set for 3.3 V, 2.5 V, or 1.8 V and all input pins are 3.3-V, 2.5-V, and 1.8-V tolerant, allowing MAX 7000B devices to be used in mixed-voltage systems.
