Complex Programmable Logic Devices Procurement Notes

Verify that the specific ordering suffix corresponds to the required speed grade (-10) and package type (TQFP-100). Confirm that the component meets the necessary environmental specifications for the intended application, as datasheet details regarding temperature ranges or compliance certifications should be cross-referenced with official manufacturer documentation prior to procurement.

Complex Programmable Logic Devices Selection Notes

Select this device when designs require 256 macrocells and 2.5-V operation within the MAX 7000B family. Ensure the design fits within the 5,000 usable gate limit and utilizes the available 100 user I/O pins. Consider the 5.0 ns tPD specification for timing closure and verify that the TQFP-100 package footprint aligns with the PCB layout constraints.

Complex Programmable Logic Devices Part Context

This component is part of the MAX 7000B series, which succeeded the MAX 7000A family by introducing 2.5-V operation while maintaining pin compatibility with previous generations. The MAX 7000B devices are designed for applications needing high performance and density in a CPLD form factor, leveraging EEPROM technology for non-volatile configuration.

Complex Programmable Logic Devices Replacement Considerations

The EPM7256BTC100-10 is pin-compatible with other MAX 7000B devices in the same package. For migration within the family, consider the EPM7128B or EPM7512B depending on resource requirements. Direct replacements from other manufacturers are not explicitly listed in the provided documentation.
