ATF1508AS-10QC160

Complex Programmable Logic Devices Overview

The ATF1508AS-10QC160 is a high-performance, high-density Complex Programmable Logic Device (CPLD) featuring 128 macrocells and up to 96 I/O pins in a 160-pin PQFP package. It utilizes electrically-erasable technology with a maximum pin-to-pin delay of 10 ns and registered operation up to 125 MHz. The device supports both 3.3V and 5.0V I/O operations via separate VCCINT and VCCIO supplies. Key specifications include 10,000 program/erase cycles, 20-year data retention, and support for In-System Programmability (ISP) via JTAG.

Complex Programmable Logic Devices Feature Summary

• 128 Macrocells with 5 product terms each, expandable to 40 via cascade logic
• 10 ns maximum propagation delay with registered operation up to 125 MHz
• In-System Programmability (ISP) via IEEE Std. 1149.1 JTAG interface
• Dual power supply architecture: VCCINT at 5.0V and VCCIO at 3.3V or 5.0V

Complex Programmable Logic Devices Applications

• PCI-compliant interface designs requiring high current drivers
• Complex logic integration replacing TTL, SSI, MSI, LSI, and classic PLDs
• Systems requiring boundary-scan testing (BST) per IEEE 1149.1
• Applications needing fast field design modifications via ISP

Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix '10' corresponds to the 10 ns delay specification required for the target application timing constraints. Confirm that the 160-lead PQFP package dimensions match the PCB footprint requirements. Ensure the design compiler supports the ATF1508AS family features such as buried feedback and cascade logic if utilizing advanced functionality.

Complex Programmable Logic Devices Selection Notes

Select this component when high density (128 macrocells) and fast performance (10 ns delay) are required in a surface-mount package. Choose the 'AS' variant over 'AL' if the automatic low-power standby mode is not needed. Ensure the design accounts for the separate VCCINT (5.0V) and VCCIO (3.3V/5.0V) power domains. Verify that the 160-pin PQFP package is suitable for the assembly process.

Complex Programmable Logic Devices Part Context

The ATF1508AS belongs to the ATF1508AS(L) series of high-performance EE PLDs from Microchip Technology (formerly Atmel). This series offers enhanced routing resources and flexible macrocell configurations compared to earlier generations. The '160' in the part number denotes the 160-lead PQFP package option, which provides up to 96 I/O pins and four dedicated input pins.
