XC9536XL-7CSG48I

Complex Programmable Logic Devices Overview

The XC9536XL-7CSG48I is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500XL family. It features 36 macrocells, 800 usable gates, and two Logic Array Blocks (LABs). The device operates at a supply voltage of 3.3V (range 3.0V to 3.6V) with a maximum operating frequency of 178 MHz and a typical propagation delay of 7 ns. Packaged in a 48-pin CSBGA, it utilizes non-volatile Flash memory for configuration, supporting in-system programming and industrial temperature ranges.

Complex Programmable Logic Devices Feature Summary

• 36 Macrocells and 800 usable logic gates across 2 LABs
• Flash-based non-volatile storage enabling instant-on operation
• In-System Programmability (ISP) via JTAG interface
• 5V tolerant I/O pins for mixed-voltage system compatibility

Complex Programmable Logic Devices Applications

• Address decoding and bus bridging in embedded systems
• Power-on reset generation and supervisor circuits
• Clock buffering and distribution networks
• General-purpose digital logic replacement

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' indicates an industrial temperature range (-40°C to +85°C) rather than commercial grade. Confirm package authenticity as the CSBGA form factor requires specialized surface-mount handling. Check current availability status as older CPLD variants may have limited stock or discontinuation notices.

Complex Programmable Logic Devices Selection Notes

Select this model when 36 macrocells are sufficient for the design logic. Ensure the PCB layout supports the 48-pin CSBGA footprint. Verify that the target system voltage aligns with the 3.3V core requirement while utilizing the 5V-tolerant inputs for interfacing with legacy components.

Complex Programmable Logic Devices Part Context

This component belongs to the XC9500XL series, which succeeded the original XC9500 line by integrating Flash memory to eliminate the need for external EPROM programmers. The XL series offers improved speed and lower power consumption compared to its predecessors while maintaining pin-compatible packages.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements include other XC9536XL variants with different speed grades or packages, such as XC9536XL-5CSG48I or XC9536XL-10CSG48I, provided the timing requirements are met.
