Overview
The ATF1502AS-15JI 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 15 ns. The device supports registered operation up to 100 MHz and utilizes an EEPROM storage type for reprogramming. It functions within a supply voltage range of 4.75 V to 5.25 V and is available in a 44-lead PLCC package. The component supports industrial temperature ranges from -40°C to +85°C.
Feature Summary
- In-System Programmability (ISP) via JTAG interface
- Flexible logic macrocells with D/T latch configurable flip-flops
- Advanced power management including pin-controlled standby mode
- PCI-compliant output drivers with programmable slew rates
Applications
- Logic integration replacing TTL, SSI, MSI, LSI, and classic PLDs
- PCI-based interface designs requiring high current drivers
- State machine initialization with power-up reset options
Procurement Notes
Verify the specific suffix 'JI' against official documentation to confirm industrial temperature range (-40°C to +85°C) and package type (PLCC-44). Ensure design files account for the 5V ±5% or ±10% supply voltage requirements depending on commercial or industrial grade specifications.
Selection Notes
Select this component when 32 macrocells are sufficient for the design logic. Consider the ATF1502ASL variant if low-power standby modes are required. Verify that the 44-lead PLCC package fits the PCB layout constraints and that JTAG pins are reserved for programming if ISP functionality is needed.
Part Context
This part belongs to the ATF1502AS family of high-density CPLDs. It shares architectural similarities with other members like the ATF1502ASV but differs in speed grade and operating conditions. The '15' indicates a 15 ns maximum delay, while 'JI' specifies the industrial temperature range and PLCC packaging.
Replacement Considerations
Direct replacements include other ATF1502AS variants with compatible packages and speeds, such as ATF1502AS-15AU44 (TQFP package). Cross-family migration may require retiming analysis due to differences in routing resources and macrocell configurations.
