Overview
The ATF1502AS-10JU44 is a high-performance, electrically-erasable Complex Programmable Logic Device (CPLD) manufactured by Microchip Technology. It features 32 macrocells with up to 40 product terms per macrocell and operates at a maximum pin-to-pin delay of 10 ns. The device supports registered operation up to 125 MHz and utilizes In-System Programmability (ISP) via JTAG. It functions within a supply voltage range of 4.5 V to 5.5 V and is available in a 44-lead PLCC package.
Feature Summary
- 32 Macrocells with expandable logic capacity up to 40 product terms per macrocell
- In-System Programmability (ISP) via standard 4-pin JTAG interface
- Flexible macrocell architecture supporting D/T latch configurable flip-flops and global register control
- Advanced power management including automatic standby and pin-controlled power-down modes
Applications
- PCI-compliant digital design applications
- High-speed state machine initialization and control
- Complex logic integration replacing TTL/SSI/MSI components
- Field programmable logic modifications via ISP
Procurement Notes
Verify the specific suffix 'JU44' against official documentation to confirm the package type and temperature grade. Ensure the design toolchain supports the ATF15xx series for proper compilation and programming. Confirm that the target system provides the required 4.5V to 5.5V supply voltage range for correct operation.
Selection Notes
Select this component when 32 macrocells are sufficient for the logic density requirements. Choose the -10 speed grade if a maximum propagation delay of 10 ns is acceptable. Consider the -7 grade for higher performance or -25 for lower cost if timing margins allow. Verify that the 44-lead PLCC package fits the PCB layout constraints.
Part Context
This part belongs to the ATF1502AS(L) family of CPLDs from Microchip Technology (formerly Atmel). The 'AS' designation indicates the standard 5V version, while 'L' variants offer enhanced low-power features. The ATF1502AS-10JU44 specifically denotes the 10 ns speed bin packaged in a 44-lead PLCC.
Replacement Considerations
Direct replacements include other ATF1502AS speed grades such as ATF1502AS-7JU44 (7 ns delay) or ATF1502AS-25JU44 (25 ns delay), provided timing requirements permit. For low-power applications, consider the ATF1502ASL series, though electrical characteristics differ significantly.
