AT17F16A-30JI

Overview

The AT17F16A-30JI is a 16-Mbit In-System Programmable (ISP) Configuration PROM designed for Field Programmable Gate Arrays. It operates at a supply voltage of 3.3V with 5V tolerant I/O pins and supports serial download speeds up to 33 MHz. The device features a 2-wire bus programming interface, low-power CMOS FLASH process, and an endurance rating of 10,000 write cycles. It is housed in a 20-lead Plastic Leaded Chip Carrier (PLCC) package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports In-System Programming via a 2-wire serial bus for flexible configuration updates.
• Provides compatibility with Altera FLEX, Excalibur, Stratix, Cyclone, and APEX devices.
• Enables cascading read-back capabilities to support additional configurations or higher-density arrays.

Applications

• Configuration memory storage for Altera FPGA devices
• Field Programmable Gate Array system reconfiguration
• Emulation of Atmel AT24CXXX serial EEPROMs

Procurement Notes

Verify the specific ordering suffix 'JI' confirms the 20-lead PLCC package and industrial temperature range (-40°C to +85°C). Ensure the component source matches Microchip Technology specifications, as the device was originally manufactured by Atmel before acquisition. Confirm lead-free (LHF) status if required by environmental regulations.

Selection Notes

Select this component when a 16-Mbit capacity is required for SRAM-based FPGA configuration. It is suitable for designs needing 5V tolerant I/O interfaces while operating on a 3.3V supply. Consider the 20-lead PLCC package for through-hole mounting requirements and verify that the 33 MHz maximum clock speed meets the system's timing constraints.

Part Context

This part belongs to the AT17FxxA series of In-System Programmable Configuration PROMs. These configurators provide cost-effective memory solutions for loading configuration programs into FPGAs. The series includes variants with different capacities and packages, such as the 8-lead LAP and 20-lead PLCC options.

Replacement Considerations

Compatible substitutes include other AT17FxxA series devices like the AT17F080A for smaller capacities or the AT17F32A for larger capacities, provided pinouts and electrical characteristics align with the design requirements.
