AT17LV010A-10QC

Overview

The AT17LV010A-10QC is a 1-Mbit (1,048,576-bit) serial EEPROM configurator designed for FPGA configuration. It operates at 3.3V or 5V with ±10% tolerance and supports industrial temperature ranges from -40°C to +85°C. The device features a 2-wire serial interface for in-system programming and direct interfacing with SRAM FPGAs. It includes programmable reset polarity, write protection, and cascading capabilities via the nCASC output. Available in a 32-lead TQFP package, it offers high endurance of 100,000 write cycles and data retention up to 90 years.

Feature Summary

• Supports In-System Programming (ISP) via a simple 2-wire bus interface
• Enables cascading of multiple devices to support higher-density FPGA arrays
• Allows user-programmable reset polarity for flexible FPGA integration
• Provides low-power standby mode with minimal current consumption

Applications

• Configuration memory for Altera FLEX and APEX FPGAs
• Configuration storage for Xilinx XC3000, XC4000, and Spartan FPGAs
• Configuration memory for Lucent ORCA and Motorola MPA1000 FPGAs
• Emulation of Atmel AT24CXXX serial EEPROMs

Procurement Notes

Verify the specific ordering suffix 'QC' corresponds to the 32-lead TQFP package and commercial temperature range as defined in the official Microchip/Atmel ordering guide. Confirm that the device version matches the required ISP compatibility, noting that newer 'B' versions may not require external MUX components for programming. Ensure supply voltage requirements align with the target system's 3.3V or 5V rails.

Selection Notes

Select this component when a 1-Mbit capacity is required for single or cascaded FPGA configuration. Choose the industrial grade variant if operation below 0°C is necessary. Consider the TQFP package only if board space permits surface-mount assembly; otherwise, verify pin-compatible alternatives like PLCC or PDIP are available for the same density. Ensure the target FPGA supports master serial mode for direct interfacing without external controllers.

Part Context

This part belongs to the AT17A series of FPGA configuration EEPROMs, originally developed by Atmel and now managed by Microchip Technology. The series provides cost-effective, non-volatile storage for loading configuration programs into SRAM-based FPGAs. Devices in this family share pin-out compatibility across densities, simplifying design upgrades. The AT17LV010A specifically targets applications requiring 1-Mbit storage capacity.

Replacement Considerations

AT17LV010A-10PC (PDIP), AT17LV010A-10JC (PLCC), AT17LV010A-10PI (Industrial PDIP), AT17LV010A-10JI (Industrial PLCC), AT17LV010A-10QI (Industrial TQFP)
