SN74V3670-10PEU

Overview

The SN74V3670-10PEU is a 3.3-V CMOS first-in, first-out (FIFO) memory with an organization of 8192 words by 36 bits. It operates at frequencies up to 166 MHz with a 6-ns read/write cycle time. The device features user-selectable input and output bus sizing for ×36, ×18, or ×9 configurations. It supports big-endian/little-endian byte representation and includes 5-V tolerant inputs. Key functional attributes include fixed low first-word latency, zero-latency retransmit capability, and master reset functionality.

Feature Summary

• Supports flexible bus matching on both read and write ports with selectable widths of 36, 18, or 9 bits.
• Provides independent read and write clocks allowing simultaneous data operations without frequency restrictions.
• Offers programmable almost-empty and almost-full flags with selectable offsets and timing modes.

Applications

• Network buffering
• Video signal processing
• Telecommunications systems
• Data communications interfaces

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature range. Confirm that the revision level aligns with current production data specifications. Ensure compatibility with system voltage levels and interface requirements before finalizing procurement orders.

Selection Notes

Select this component when deep memory depth combined with high-speed operation is required. Consider the SN74V3670 specifically for applications needing 8192-word capacity. Evaluate bus-matching needs to determine if the configurable port widths suit the system architecture.

Part Context

This part belongs to the SN74V36xx series of high-performance submicron CMOS FIFO memories. The series includes variants with different depths ranging from 1024 to 32768 words. All members share similar control logic and feature sets while differing in storage capacity.

Replacement Considerations

Compatible substitutes within the same family include SN74V3640, SN74V3650, SN74V3660, SN74V3680, and SN74V3690. These parts share identical pinouts and control logic but offer different memory depths.
