Overview
The ATF1502ASV-15AU44 is a high-performance, electrically-erasable Complex Programmable Logic Device (CPLD) from Microchip Technology. It features 32 macrocells with up to 36 inputs and 32 bi-directional I/O pins in a 44-pin TQFP package. The device operates within a 3.0V to 3.6V supply range and delivers a maximum pin-to-pin delay of 15 ns, supporting registered operation up to 77 MHz. Key specifications include In-System Programmability (ISP) via JTAG, 10,000 program/erase cycles, and an industrial temperature range of -40°C to +85°C.
Feature Summary
- 32 Macrocells with 5 product terms each, expandable to 40 via cascade logic
- Maximum 15 ns pin-to-pin delay and 77 MHz registered frequency
- In-System Programmability (ISP) using standard 4-pin JTAG interface
- Pin-controlled power-down mode reducing current to below 15 mA
Applications
- Complex logic integration replacing TTL, SSI, MSI, or classic PLDs
- High-speed state machine implementations requiring fast registered feedback
- PCI-compliant digital design applications
- Systems requiring non-volatile configuration with field-upgrade capabilities
Procurement Notes
Verify the specific suffix 'AU44' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with 3.3V logic levels and JTAG programming interfaces during sourcing.
Selection Notes
Select this component for designs requiring 32 macrocells and 15 ns speed in a 44-pin surface-mount package. Consider the ATF1502ASV-15AC44 if commercial temperature range (0°C to 70°C) suffices, as it shares identical electrical characteristics.
Part Context
This part belongs to the ATF15xx series of EEPROM-based CPLDs. It utilizes Atmel's proven electrically-erasable technology, offering high density and low power consumption compared to older EPROM-based devices.
Replacement Considerations
ATF1502ASV-15AC44: Commercial temperature variant with identical electrical specs.
FAQ
What is the maximum operating frequency for registered operations?
The device supports registered operation up to 77 MHz.
How many product terms are available per macrocell?
Each macrocell has five product terms, which can be expanded to up to 40 product terms using cascade logic.
Is the device programmable after installation on the PCB?
Yes, it supports In-System Programmability (ISP) via the standard 4-pin JTAG interface.
