Overview
The ATF1504ASVL-20AU44 is a high-density, electrically-erasable CPLD from Microchip Technology's ATF15xx series. It features 64 macrocells with up to 40 product terms each and operates within a 3.0V to 3.6V supply range. The device supports In-System Programmability (ISP) via JTAG and offers industrial temperature operation (-40°C to +85°C). Key electrical specifications include a maximum pin-to-pin delay of 20 ns and registered operation up to 66 MHz. It utilizes EEPROM technology for reprogrammability and includes advanced power management features such as automatic standby mode.
Feature Summary
- 64 Macrocells with expandable logic resources
- In-System Programmability (ISP) via JTAG interface
- Automatic low-power Standby mode (ATF1504ASVL)
- Industrial temperature range (-40°C to +85°C)
Applications
- Logic replacement for TTL/SSI/MSI/LSI circuits
- State machine implementation
- Address decoding and bus interfacing
Procurement Notes
Verify the specific suffix 'AU44' corresponds to the 44-Lead TQFP package and -20 speed grade in official Microchip documentation. Confirm RoHS compliance status and current production lifecycle status directly with the manufacturer or authorized distributors, as availability may vary.
Selection Notes
Select this component for designs requiring 64 macrocells and ISP capability at 3.3V. Ensure the design compiler supports the ATF1504ASVL family. Consider the 20 ns delay specification for timing closure. Verify that the application requires the low-power standby features inherent to the ASVL variant over the standard ASV.
Part Context
This part belongs to the ATF1504ASV(L) family of Complex Programmable Logic Devices. It shares architectural similarities with other members like ATF1504ASV-15AU44 but differs in speed grade (-20 vs -15) and power characteristics (ASVL vs ASV). The AU44 suffix denotes the 44-TQFP package option.
Replacement Considerations
Direct replacements must match the 64 macrocell count, 44-TQFP package, and 3.3V operation. Check for equivalent speed grades (e.g., -15 or -20) and ensure the replacement supports ISP if required. Verify thermal and electrical compatibility.
