The component supports unidirectional data transfer with a maximum clock frequency of 50 MHz and a typical access time of 12 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and has a maximum power supply current of 125 mA. The device is housed in a 56-TSSOP package and functions within an operating temperature range of 0°C to 70°C.

FIFOs Memory Feature Summary

• Asynchronous dual FIFO architecture enabling simultaneous independent read and write operations for multiprocessing applications.
• 9-bit wide data array designed to accommodate user-defined control and parity bits for error checking.
• Supports rate buffering between high-speed processors and slower peripherals through first-in/first-out data handling.

FIFOs Memory Applications

• Multiprocessing systems requiring asynchronous data exchange between multiple processors.
• Rate buffering interfaces between high-speed digital signal processors and lower-speed peripheral devices.
• Data communications applications utilizing the 9-bit width for transmission error checking via parity bits.

FIFOs Memory Procurement Notes

Verify RoHS compliance status carefully, as historical records indicate variations across the 7285 series. Confirm the specific suffix PA8 against the manufacturer's latest datasheet to ensure accurate pinout and electrical specifications. Check for end-of-life notices or obsolescence warnings prior to procurement, as availability may be restricted.

FIFOs Memory Selection Notes

Select this component when designing systems that require asynchronous dual-port memory with a 9-bit data width. Ensure the system voltage aligns with the 4.5 V to 5.5 V operating range. Consider the 56-TSSOP package constraints for PCB layout. Verify if the 50 MHz speed meets the timing requirements of the target application interface.

FIFOs Memory Part Context
