XC9536XL-5VQG44C

Complex Programmable Logic Devices Overview

The AMD XC9536XL-5VQG44C is a Complex Programmable Logic Device (CPLD) from the XC9500XL family, manufactured by AMD. It features 36 macrocells and 800 usable gates within two logic array blocks. The device operates at a supply voltage of 3.0 V to 3.6 V with a typical current consumption of 10 mA. Key electrical parameters include a maximum operating frequency of 100 MHz, a maximum propagation delay of 10 ns, and a maximum clock-to-output delay of 12 ns. It utilizes Flash memory technology for non-volatile storage and supports in-system programming. The component is housed in a 44-pin Very Thin Quad Flat Package (VQFP) with a 10x10 mm footprint.

Complex Programmable Logic Devices Feature Summary

• Flash-based non-volatile architecture enabling unlimited reprogramming cycles without external erasure.
• High-speed performance with 10 ns max propagation delay and 100 MHz system frequency.
• Low power consumption with 10 mA operating current and support for 3.3 V I/O levels.
• In-system programmability via JTAG interface for simplified design verification.

Complex Programmable Logic Devices Applications

• Replacement for legacy E²PROM-based CPLDs in existing hardware designs.
• Simple state machine implementation and glue logic in industrial control systems.
• Address decoding and bus bridging in embedded computing architectures.
• Level shifting between 5 V and 3.3 V domains in mixed-signal circuits.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'C' indicates commercial temperature range (-40°C to +85°C). Confirm package integrity as the VQFP-44 is sensitive to moisture. Check for obsolescence notices from AMD/Xilinx as this part may be discontinued or subject to limited availability. Ensure compatibility with existing JTAG programming tools for Flash-based devices.

Complex Programmable Logic Devices Selection Notes

Select this model when upgrading from the older XC9536 series due to its lower voltage operation (3.3 V vs 5 V) and improved speed. Ensure the design requires only 34 I/O pins and 36 macrocells. Verify that the PCB layout accommodates the 0.8 mm pitch of the VQFP-44 package. Consider thermal dissipation requirements given the low static power consumption.

Complex Programmable Logic Devices Part Context

The XC9536XL-5VQG44C belongs to the XC9500XL family, which succeeded the original XC9500 series. This family introduced Flash memory technology, eliminating the need for UV erasure and allowing higher density in smaller packages. The XL series offers faster speeds and lower power compared to its predecessors, making it suitable for modern 3.3 V systems.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements are limited due to the transition from 5 V to 3.3 V operation. The XC9536 (original 5 V version) is not electrically compatible without level shifting. Alternative CPLDs from other manufacturers require careful review of I/O voltage tolerances and programming interfaces.
