ATF1508ASV-15QC160

Complex Programmable Logic Devices Overview

The ATF1508ASV-15QC160 is a high-performance, high-density Complex Programmable Logic Device (CPLD) manufactured by Microchip Technology. It features 128 macrocells and operates within a 3.0V to 3.6V supply range. The device supports up to 96 bi-directional I/O pins and four dedicated input pins in the 160-lead PQFP package. Key electrical parameters include a maximum pin-to-pin delay of 15 ns and a maximum clock frequency of 100 MHz. It utilizes electrically-erasable technology with In-System Programmability (ISP) via JTAG.

Complex Programmable Logic Devices Feature Summary

• Enhanced routing resources with global bus and regional foldback bus for efficient logic implementation
• Advanced power management including automatic standby mode and pin-controlled power-down

Complex Programmable Logic Devices Applications

• Logic integration replacing TTL, SSI, MSI, LSI, and classic PLDs
• State machine initialization with built-in power-up reset feature
• Boundary-scan testing using JTAG standard protocols
• PCI-compliant digital logic design

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized Microchip distributors. Confirm package integrity for the 160-lead PQFP form factor. Ensure design files account for the specific -15 speed grade timing constraints. Check for RoHS compliance documentation if required for assembly processes.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 128 macrocells with 3.3V operation and 15 ns performance. Compare against the ATF1508ASV-20QC160 if lower speed requirements allow for potential cost or availability differences. Ensure the 160-lead PQFP footprint matches the PCB layout. Verify that the 3.0V-3.6V voltage range aligns with the system power supply.

Complex Programmable Logic Devices Part Context

This component belongs to the ATF1508ASV family of Electrically Erasable Programmable Logic Devices (EEPLDs). It shares architectural similarities with other variants in the series but differs in operating voltage (3.3V vs 5V) and package options. The 'V' suffix denotes the 3.3V version, while 'QC160' specifies the commercial temperature range and 160-lead PQFP package.
