General Description
MAX 7000Adevices (including MAX 7000AE) devices are high-density, highperformance devices based on Altera’s second-generation MAX architecture. Fabricated with advanced CMOS technology, the EEPROMbased MAX 7000A devices operate with a 3.3-V supply voltage and provide 600 to 10,000 usable gates, ISP, pin-to-pin delays as fast as 4.5 ns, and counter speeds of up to 227.3 MHz. MAX 7000A devices in the -4, -5, -6, -7, and some -10 speed grades are compatible with the timing requirements for 33 MHz operation of the PCI Special Interest Group (PCI SIG) PCI Local Bus Specification. EPM7032AELC44-4N Altera IC MAX 7000A CPLD 32 PLCC44
The MAX 7000Adevices architecture supports 100% transistor-to-transistor logic (TTL) emulation and high-density integration of SSI, MSI, and LSI logic functions. It easily integrates multiple devices including PALs, GALs, and 22V10s devices. MAX 7000A devices are available in a wide range of
packages, including PLCC, BGA, FineLine BGA, Ultra FineLine BGA, PQFP, and TQFP packages.EPM7032AELC44-4N Altera IC MAX 7000A CPLD 32 PLCC44
MAX 7000A devices use CMOS EEPROM cells to implement logic functions. The user-configurable MAX 7000A 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.
EPM7032AELC44-4N Altera IC MAX 7000A CPLD 32 PLCC44
MAX 7000A devices contain from 32 to 512 macrocells that are combined into groups of 16 macrocells, called logic array blocks (LABs). EPM7032AELC44-4N Altera IC MAX 7000A CPLD 32 PLCC44. Each macrocell has a programmable-AND/fixed-OR array and a configurable register with independently programmable clock, clock enable, clear, and preset functions. To build complex logic functions, each macrocell can be supplemented with both shareable expander product terms and highspeed parallel expander product terms, providing up to 32 product terms per macrocell. MAX 7000Adevices 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 at 50% or lower power while adding only a nominal timing delay. MAX 7000A 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 7000Adevices can be set for 2.5 V or 3.3 V, and all input pins are 2.5-V, 3.3-V, and 5.0-V tolerant, allowing MAX 7000A devices to be used in mixed-voltage systems.
