Texas Instruments SN74V283-10GGM

Overview

SN74V283-10GGM from Texas Instruments is a 32,768 × 18 / 65,536 × 9 high-speed CMOS FIFO memory with independent read/write clocks, 166-MHz operation, 6-ns read/write cycle time, and user-selectable ×9/×18 bus sizing - deployed in network buffering, DSP interfacing, and video data stream synchronization.

For engineers reviewing the SN74V283-10GGM datasheet, SN74V283-10GGM pinout, SN74V283-10GGM application, or SN74V283-10GGM equivalent, key selection criteria include FWFT vs. standard timing mode, retransmit latency configuration (zero- or normal-latency), big/little-endian data formatting, programmable almost-empty/full flag offsets, and 5-V-tolerant input compatibility with 3.3-V core operation.

Technical Context

This FIFO implements dual-clock asynchronous architecture with independent WCLK and RCLK domains supporting 0–166 MHz operation and zero inter-clock frequency dependency. It integrates configurable read/write port widths (×9 or ×18), selectable first-word fall-through (FWFT) or standard timing modes, and dual-mode retransmit control (zero-latency enabled via RM pin during master reset).

Flag logic supports five status outputs - EF/OR, FF/IR, HF, PAE, PAF - with PAE/PAF independently programmable via serial or parallel loading and configurable as synchronous or asynchronous using PFM. Bus-matching, endian selection (BE), and interspersed parity (IP) are all set during master reset and retained through partial reset (PRS).

Key Specifications

FAQ

What is the maximum operating frequency of the SN74V283-10GGM?

The SN74V283-10GGM supports up to 166 MHz for both read and write clocks, enabling high-throughput data transfer in demanding applications like real-time video streaming and packet switching. This specification is guaranteed across commercial temperature range and 3.3-V supply, with 6-ns read/write cycle time directly derived from this frequency rating. The SN74V283-10GGM maintains full functionality even when RCLK and WCLK operate at different frequencies or phases.

Does the SN74V283-10GGM support first-word fall-through (FWFT) mode?

Yes, the SN74V283-10GGM supports FWFT mode, selected by asserting FWFT/SI high during master reset. In FWFT mode, the first word written to an empty FIFO appears on Q0–Q17 after exactly three RCLK rising edges without requiring REN assertion. Subsequent words still require REN activation. This behavior is intrinsic to the SN74V283-10GGM's architecture and documented in SCAS669D Section 3. The SN74V283-10GGM also supports standard mode for applications requiring strict read-enabling discipline.

How is retransmit latency configured on the SN74V283-10GGM?

Retransmit latency on the SN74V283-10GGM is configured via the RM pin during master reset: a low level selects zero-latency mode, where the first retransmitted word appears on Q-bus synchronously with the RCLK edge that samples RT low; a high level selects normal latency. This setting is latched and remains active until next MRS. The SN74V283-10GGM's zero-latency capability is confirmed in datasheet Section 5 and enables precise replay in protocol analyzers and test equipment without introducing timing uncertainty.

Can the SN74V283-10GGM interface directly with 5-V logic devices?

Yes, the SN74V283-10GGM features 5-V-tolerant inputs - all control and data input pins (WEN, REN, WCLK, RCLK, D0–D17, etc.) accept 0–5.5-V signals while operating from a 3.3-V supply. This eliminates external level shifters when interfacing with legacy 5-V microcontrollers or FPGAs. However, outputs (Q0–Q17) are not 5-V tolerant and must connect only to 3.3-V–compatible receivers. This 5-V-tolerant input specification is explicitly stated in the SN74V283-10GGM datasheet front page and Section 7.

What package type does the SN74V283-10GGM use?

The SN74V283-10GGM uses a 100-pin Ball Grid Array (BGA) package designated as GGM, corresponding to TI's PZ mechanical outline. This package is verified in the SCAS669D datasheet Figure 2 (GGM PACKAGE top view) and supports fine-pitch surface-mount assembly for high-density PCBs. The SN74V283-10GGM's GGM package differs from the PZA (80-pin TQFP) variant used by other members of the SN74V2xx3 family and is not pin-compatible with TQFP versions.
