XC9536XV-7PC44C

Complex Programmable Logic Devices Overview

The XC9536XV-7PC44C is a Flash-based Complex Programmable Logic Device (CPLD) from the Xilinx XC9500XV family, manufactured by AMD. It features 36 macrocells and supports up to 34 I/O lines within a 44-pin Plastic Quad Flatpack (PQFP) package. The device operates with a maximum clock frequency of 83 MHz and has a propagation delay of 7.5 ns. It utilizes CMOS technology and includes non-volatile Flash memory for configuration retention without external battery support.

Complex Programmable Logic Devices Feature Summary

• Non-volatile Flash memory architecture eliminates the need for external configuration devices or batteries.
• Supports in-system programmability via JTAG interface for flexible design updates.
• High-density logic with 36 macrocells and 800 usable gates in a compact 44-pin PQFP package.
• Operates at standard 3.3V supply voltage with low power consumption characteristics.

Complex Programmable Logic Devices Applications

• General-purpose digital logic replacement for legacy TTL/CMOS circuits.
• Address decoding and bus bridging in embedded systems.
• State machine implementation for control logic applications.
• Interface translation between different voltage domains or protocols.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'XV' indicates the extended temperature range variant if required for your application environment. Confirm the package type is PQFP-44 rather than PLCC or LCC variants. Check for RoHS compliance status as manufacturing sources may vary. Ensure programming tools support the XC9500XV family specifically, as older tools may require updates for Flash-based devices.

Complex Programmable Logic Devices Selection Notes

Select this component when non-volatile configuration is critical to avoid external EEPROM dependencies. Compare against XC9536XL for potential performance improvements if lower delay times are needed. Consider pin count requirements carefully as only 34 pins are available for I/O out of the 44 total pins. Evaluate power budget constraints as Flash CPLDs have static current draw distinct from SRAM-based FPGAs.

Complex Programmable Logic Devices Part Context

This part belongs to the AMD (formerly Xilinx) XC9500XV series, an evolution of the industry-standard XC9500 CPLD line. The 'XV' designation typically denotes enhanced features such as improved security bits or extended operating conditions compared to the base XC9500 series. It serves as a drop-in replacement for many older GAL and PAL designs while offering reprogrammability.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements include other XC9536 variants like XC9536-7PC44C or XC9536XL-7PC44C, though electrical parameters may differ slightly. Cross-family replacements from Intel (Altera) MAX 3000A series may require schematic redesign due to architectural differences. Verify that any substitute supports JTAG programming if in-system programming is required.
