ATF1508ASV-15QI160

Complex Programmable Logic Devices Overview

The ATF1508ASV-15QI160 is a high-performance, high-density Complex Programmable Logic Device (CPLD) manufactured by Microchip Technology. It features 128 macrocells with up to 100 inputs and operates within a 3.0V to 3.6V supply range. The device provides a maximum pin-to-pin delay of 15 ns and supports registered operation up to 77 MHz. It utilizes electrically-erasable technology for complete reprogrammability and includes In-System Programmability (ISP) via JTAG. The component is housed in a 160-lead PQFP package and is rated for industrial temperature ranges from -40°C to +85°C.

Complex Programmable Logic Devices Feature Summary

• Maximum 15 ns pin-to-pin delay with enhanced routing resources
• In-System Programmability (ISP) via 4-pin JTAG interface compliant with IEEE Std. 1149.1
• Advanced power management including automatic standby and pin-controlled power-down modes

Complex Programmable Logic Devices Applications

• Logic integration replacing TTL, SSI, MSI, LSI, and classic PLDs
• PCI-compliant system designs requiring fast ISP capabilities
• Industrial applications operating within -40°C to +85°C temperature ranges

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'QI' against official Microchip documentation to confirm package type and temperature grade. Confirm current production status as legacy CPLD families may have discontinuation notices. Ensure design files support the 160-lead PQFP footprint and JTAG boundary-scan requirements.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 128 macrocells and 160 pins with 3.3V operation. Compare against the ATF1508ASVL variant if lower standby current (5 µA) is critical. Verify that the 15 ns speed grade meets the system timing requirements for registered and combinatorial paths.

Complex Programmable Logic Devices Part Context

This part belongs to the ATF1508ASV family of Electrically Erasable PLDs. It shares architectural similarities with other ATF15xxSE devices but is distinguished by its 3.3V operating voltage and specific pin count. The 'ASV' designation indicates the standard performance version within the low-voltage series.
