SN74ABT3612-30PCB

FIFOs Memory Overview

The SN74ABT3612 is a high-speed, low-power BiCMOS bidirectional clocked FIFO memory containing two independent 64 × 36 dual-port SRAMs. It supports clock frequencies up to 67 MHz and features fast access times of 10 ns. The device includes programmable almost-full and almost-empty flags synchronized to respective port clocks, passive parity checking on each port, and selectable parity generation for reads. Communication between ports can bypass the FIFOs via two 36-bit mailbox registers. The PCB package variant utilizes a 120-pin Thin Quad Flat configuration.

FIFOs Memory Feature Summary

• Contains two independent 64 × 36 clocked FIFOs buffering data in opposite directions
• Includes mailbox-bypass registers for direct communication between ports
• Features programmable almost-full and almost-empty status flags
• Supports passive parity checking and selectable parity generation

FIFOs Memory Applications

• Buffering data in opposite directions between microprocessors
• Synchronous control interfaces between buses
• High-bandwidth computing applications requiring parity verification

FIFOs Memory Procurement Notes

Verify that the specific ordering suffix matches the required physical package dimensions and pinout. Confirm the temperature range rating aligns with the operational environment requirements. Ensure the component revision corresponds to the intended design specifications before finalizing procurement orders.

FIFOs Memory Selection Notes

Select this component when designing systems requiring dual-port asynchronous or coincident clock synchronization. Consider the 120-pin PCB package constraints for board layout. Evaluate the need for mailbox bypass functionality and parity error handling capabilities during the architecture phase.
