• Supports In-System Programming (ISP) using IEEE 1149.1 JTAG interface.
• Utilizes non-volatile Flash technology for configuration retention without external memory.
• Provides 52 available I/O pins for system connectivity.

Complex Programmable Logic Devices Applications

• Interface bridging between different voltage domains or protocol converters.
• Address decoding and chip select generation in embedded systems.
• Simple state machine implementation for control logic.
• Replacement for legacy GAL or PAL devices in existing designs.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'Z' against the manufacturer's current ordering guide, as it may denote specific environmental or reliability qualifications distinct from standard variants. Confirm the package type corresponds to the 68-ball TFBGA footprint during PCB layout. Ensure that the design toolchain supports the MAX II family architecture for successful compilation and programming.

Complex Programmable Logic Devices Selection Notes

Select this component when a low pin count CPLD with Flash-based non-volatility is required. Compare the 52 I/O count against system requirements; if more I/O is needed, consider the EPM240T100 variant. Evaluate power consumption needs, as the MAX II series offers low static and dynamic power options suitable for battery-operated applications.

Complex Programmable Logic Devices Part Context

This part belongs to the Altera MAX II family, which bridges the gap between simple programmable logic and complex FPGAs. The MAX II series is characterized by its ease of use, low cost, and Flash-based architecture, allowing for rapid prototyping and high-volume production without the need for external configuration devices.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements within the MAX II family include EPM240T100C5N (100-pin) if package changes are acceptable. For functional equivalents with different packaging, check the EPM240T100C7N. Always verify electrical parameters and I/O drive strengths before substituting.
