XCR3512XL-10PQ208I

Overview

The XCR3512XL-10PQ208I is a complex programmable logic device (CPLD) from AMD's XC5000XL family, housed in a 208-pin PQFP package. It features 12 macrocells and supports up to 10 ns propagation delay. The device operates with a supply voltage range of 2.7V to 3.6V and includes 4 I/O blocks for flexible interface configurations. Designed for high-density applications, it offers non-volatile configuration storage via Flash technology, eliminating the need for external configuration memory devices.

Feature Summary

• Flash-based non-volatile configuration for instant-on operation without external PROMs
• 12 macrocells with 10 ns maximum propagation delay in 208-pin PQFP package
• Supports 2.7V to 3.6V VCC operating voltage for low-power applications
• In-system programmable via JTAG interface for field updates

Applications

• Address decoding and bus bridging in embedded systems
• State machine implementation for control logic
• Translation between different voltage domains or protocol interfaces
• Replacement for legacy GALs and PALs in modern designs

Procurement Notes

Verify the suffix 'I' indicates industrial temperature range (-40°C to +85°C). Confirm the 'XL' designation corresponds to the Flash-based XC5000XL family rather than older EPROM versions. Ensure the PQ208 package matches the footprint requirements on the target PCB. Check for RoHS compliance status if required by specific regional regulations.

Selection Notes

Select this component when non-volatile configuration is required without external memory overhead. The 12 macrocell count suits moderate complexity logic functions. Consider the 10 ns speed grade if timing constraints are tight. Verify that the 208-pin package size fits within the available board space compared to smaller pin-count alternatives like the 100-pin variants.

Part Context

This part belongs to AMD's XC5000XL series, which introduced Flash technology to replace UV-erasable EPROM cells found in earlier XC5000 parts. The XL series provides higher density and lower power consumption while maintaining compatibility with existing design tools. The PQ208 package offers a balance between pin count and physical footprint for mid-range CPLD applications.

Replacement Considerations

Direct replacements include other XC5000XL variants with similar macrocell counts but different package types, such as XCR3512XL-10TQ100 for surface mount QFP packages. Cross-family migration to newer CoolRunner-II or UltraScale+ devices requires significant redesign due to architectural differences. Verify pinout compatibility before substituting with older XC5000 EPROM-based parts.
