ATF1504ASV-15QC100

Complex Programmable Logic Devices Overview

The ATF1504ASV-15QC100 is a high-density, electrically erasable complex programmable logic device (CPLD) manufactured by Microchip Technology. It features 64 macrocells with up to 68 inputs and I/Os, operating within a 3.0V to 3.6V supply range. The device delivers a maximum pin-to-pin propagation delay of 15 ns and supports registered operation at frequencies up to 77 MHz. It utilizes EEPROM technology for reprogramming, offering in-system programmability via JTAG. The component is housed in a 100-lead TQFP package and is rated for industrial temperature ranges from -40°C to +85°C.

Complex Programmable Logic Devices Feature Summary

• 64 Macrocells with 5 product terms each, expandable to 40 via cascade logic
• In-System Programmability (ISP) using the standard 4-pin JTAG interface
• Flexible Logic Macrocell supporting D/T/Latch flip-flops and configurable output slew rates
• Advanced power management including pin-controlled standby and per-macrocell reduced-power options

Complex Programmable Logic Devices Applications

• Complex logic integration replacing multiple TTL or MSI components
• State machine implementation requiring robust power-up reset initialization
• High-speed digital signal processing with registered feedback paths
• PCI-compliant interface design utilizing boundary-scan testing capabilities

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'QC100' against the official datasheet to confirm the 100-lead TQFP package and industrial temperature grade (-40°C to +85°C). Ensure that the 3.3V operating voltage requirements are compatible with the target system's VCCIO and VCCINT supplies before procurement.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells and high-speed performance (15 ns delay) are required in a surface-mount package. Consider the ATF1504ASVL variant if automatic low-power standby modes are necessary. Verify that the design compiler supports the enhanced routing resources and buried feedback features available in this architecture.

Complex Programmable Logic Devices Part Context

This component belongs to the ATF1504ASV(L) family of CPLDs. It shares architectural similarities with other devices in the series but differs in package options and specific speed grades. The 'ASV' designation indicates standard power consumption, while the 'L' suffix denotes low-power variants with additional standby features.
