Overview
The ATF1502ASV-20JC44 is a high-performance, electrically-erasable Complex Programmable Logic Device (CPLD) manufactured by Microchip Technology. It features 32 logic macrocells and up to 36 inputs within a 44-pin PLCC package. The device operates on a 3.0V to 3.6V supply voltage and supports In-System Programmability (ISP) via JTAG. Key electrical parameters include a maximum pin-to-pin delay of 20 ns, a registered operation frequency up to 77 MHz, and an industrial temperature range of -40°C to +85°C.
Feature Summary
- Contains 32 macrocells with 5 product terms each, expandable to 40 via cascade logic.
- Supports In-System Programmability (ISP) using the standard 4-pin JTAG interface.
- Features advanced power management including pin-controlled standby mode at 0.75 mA.
- Includes programmable pin-keeper circuits to prevent floating inputs and reduce noise.
Applications
- Replacing TTL, SSI, MSI, LSI, and classic PLDs in digital logic designs.
- Implementing state machines requiring robust power-up reset initialization.
- Designs utilizing boundary-scan testing for manufacturing verification.
Procurement Notes
Verify that the specific ordering suffix corresponds to the required package type and temperature grade. Confirm that the design compiler settings match the target speed grade (-20 variant). Ensure programming hardware supports the ISP protocol if field updates are planned.
Selection Notes
Select this part when 32 macrocells are sufficient for the logic density requirements. The -20 speed grade offers a 20 ns delay compared to the faster -15 grade. Consider the PLCC-44 package availability against TQFP alternatives. Verify power supply stability within the 3.0V to 3.6V range for reliable operation.
Part Context
This component belongs to the ATF1502ASV family of EEPROM-based CPLDs. It utilizes Atmel's proven electrically-erasable technology, allowing complete reprogrammability. The device is designed to integrate logic functions while offering enhanced routing resources to improve design success rates for pin-locked modifications.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing should be performed carefully as speed grades and package types vary within the ATF1502ASV series.
