AT17LV020A-10JC

Configuration PROMs For FPGAs Overview

The AT17LV020A-10JC is a 2M-bit serial EEPROM configurator designed for Altera FLEX devices. It operates at 3.3V ± 5% with a commercial temperature range of 0°C to +70°C. The device uses a simple serial interface to store configuration programs for Field Programmable Gate Arrays (FPGAs). It supports In-System Programming via a 2-wire bus and features a system-friendly READY pin. The memory organization allows for cascading to support higher-density arrays.

Configuration PROMs For FPGAs Procurement Notes

Verify the specific voltage variant, as the 'LV' suffix denotes 3.3V operation while standard versions are 5V. Confirm the package type is the 20-lead PLCC. Ensure the temperature grade matches the application requirements, as industrial variants exist. Check for RoHS compliance status if required by the manufacturing process.

Configuration PROMs For FPGAs Selection Notes

Select this component when configuring Altera FLEX devices requiring 2M-bit capacity. Choose the LV version for 3.3V systems and the standard C version for 5V systems. Consider cascading capabilities if the target FPGA density exceeds single-device limits. Verify that the 2-wire programming interface is compatible with the available programming equipment.

Configuration PROMs For FPGAs Part Context

This part belongs to the AT17A Series of FPGA Configuration EEPROMs. These devices provide a cost-effective solution for programming Altera FLEX devices. The series includes both 5V and 3.3V versions, packaged in a 20-lead PLCC. They emulate Atmel's AT24CXXX serial EEPROMs and support simple interfaces to SRAM FPGAs.

Configuration PROMs For FPGAs Replacement Considerations

Use 2M density parts to replace Altera EPC2 devices.
