• Single 1.8V power supply operation with 8192 bits of embedded RAM
• System-in-programmable via JTAG interface
• High-speed performance with 6.2 ns max propagation delay

Complex Programmable Logic Devices Applications

• Interface bridging between different voltage domains
• Address decoding and bus switching in embedded systems
• Simple state machine implementation for control logic
• Replacement for legacy GAL or PAL devices

Complex Programmable Logic Devices Procurement Notes

Verify RoHS compliance status through official Intel/Altera documentation, as conflicting data exists regarding lead-free certification. Confirm the specific suffix 'G' indicates Green/RoHS-compliant material composition. Check for active production status and potential obsolescence notices from the manufacturer before procurement planning.

Complex Programmable Logic Devices Selection Notes

Select this component when a single 1.8V supply is available and moderate I/O count (212 pins) is required. Compare against the EPM1270F256C5N if a dual 2.5V/3.3V supply capability is necessary instead of strict 1.8V operation. Ensure the 256-FBGA package footprint matches the PCB design constraints.

Complex Programmable Logic Devices Part Context

This part is a member of the Intel MAX II CPLD family, designed for low-cost, low-power applications requiring non-volatile programmability. It serves as a successor to older GAL technologies and complements larger FPGA families like Cyclone by handling simpler logic tasks efficiently.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible alternatives within the same density include the EPM1270T144 variants if package size reduction is acceptable. Cross-family migration to MAX V may offer improved power efficiency but requires software toolchain updates.
