Overview
The ATF1502ASVL-30AC44 is a Complex Programmable Logic Device (CPLD) from Microchip Technology's ATF15xxASV/L series. It features 32 macrocells and operates within a supply voltage range of 3.0V to 3.6V. The device utilizes EEPROM storage technology for non-volatile configuration retention. It supports In-System Programming (ISP) with a minimum of 10,000 program/erase cycles. The component is housed in a 44-pin TQFP package and is designed for surface mount installation.
Feature Summary
- 32 Macrocells with 1500 system gates
- EEPROM-based non-volatile memory
- In-System Programmable (ISP)
- 3.0V to 3.6V operating voltage
Applications
- Logic replacement in low-power embedded systems
- Address decoding and bus interfacing
- State machine implementation
- Timing control circuits
Procurement Notes
Verify the specific suffix 'AC44' against official Microchip documentation to confirm package and temperature grade details. Confirm current production status as older ATF15xx variants may be subject to discontinuation notices. Ensure compatibility with 3.3V logic levels required by this specific model variant.
Selection Notes
Select this model when 32 macrocells are sufficient for the design logic requirements. The 3.0V-3.6V voltage range makes it suitable for modern low-voltage applications compared to the 5V ATF1502AS variants. Consider the 30ns propagation delay for timing constraints. Verify that the TQFP-44 package fits the PCB footprint constraints.
Part Context
This part belongs to the ATF15xxASV/L family, which offers lower power consumption than the standard ATF15xxAS series. The 'L' suffix typically denotes the low-voltage 3.3V operation. It serves as a drop-in replacement for legacy PALs/GALs in designs requiring reprogrammability without external configuration memory.
Replacement Considerations
Direct pin-compatible replacements within the same family include ATF1502ASVL-10AC44 or ATF1502ASVL-15AC44 for faster switching speeds. For higher density needs, consider the ATF1504ASVL series. Verify that any substitute maintains the 3.3V I/O voltage level.
