AT17F32-30BJC

Overview

The AT17F32-30BJC is a 32-Mbit In-System Programmable Configuration PROM designed for Field Programmable Gate Arrays. It operates on a single 3.3V supply with 5V tolerant I/O pins and supports serial download speeds up to 33 MHz. The device features a low-power CMOS FLASH process, offering an endurance of 10,000 write cycles typical. It is housed in a 44-lead PLCC package and includes support for cascading read-back to accommodate higher-density arrays or additional configurations.

Feature Summary

• Supports In-System Programming via a 2-wire bus
• Enables simple interface to SRAM FPGAs
• Provides compatibility with major FPGA families including Altera, Lattice, and Xilinx devices
• Allows storage of multiple configuration bitstreams through page select functionality

Applications

• Configuration of Atmel AT40K and AT94K FPGAs
• Configuration of Altera FLEX, APEX, and Stratix devices
• Configuration of Lattice Semiconductor ORCA FPGAs
• Configuration of Xilinx Spartan and Virtex FPGAs

Procurement Notes

Verify the specific ordering suffix to confirm the operating temperature range and environmental compliance. The 'J' suffix indicates commercial grade operation, while 'I' denotes industrial grade. Ensure the package type matches the required 44-lead PLCC footprint. Confirm that the programming equipment supports the 2-wire serial protocol for ISP operations.

Selection Notes

Select this component when a cost-effective configurator for SRAM-based FPGAs is required. It is suitable for designs needing fast serial download capabilities and low standby power consumption. Consider the 44-lead PLCC package constraints and verify compatibility with the target FPGA's master serial mode requirements before implementation.

Part Context

This device belongs to the AT17F Series of Configurators, which provide programmable memory solutions for FPGA initialization. The series utilizes a low-power CMOS FLASH process and supports emulation of serial EEPROMs. It is designed to simplify system reconfiguration by allowing a single device to hold multiple bitstream files.

Replacement Considerations

Compatible replacements include other devices within the AT17F series such as the AT17F32-30BJI for industrial temperature ranges. Verify pinout and electrical specifications against current design requirements when substituting.
