Product details
Overview
71V3577S75PFG from Renesas Electronics is a 128K × 36-bit (4.608 Mb), 3.3V synchronous SRAM with flow-through output architecture, 7.5 ns access time at up to 117 MHz, and burst counter support for high-bandwidth cache and buffer applications in networking and telecom systems.
For engineers reviewing the 71V3577S75PFG datasheet, 71V3577S75PFG pinout, 71V3577S75PFG application, or 71V3577S75PFG equivalent, this device delivers deterministic timing, single-cycle deselect, linear/interleaved burst mode selection via LBO, and industrial-grade reliability across –40°C to +85°C.
Technical Context
The 71V3577S75PFG implements a synchronous, clock-driven interface with registered address and data inputs, flow-through (unregistered) outputs, and internal burst address generation triggered by ADV. Its dual-bank chip select (CS0/CS1) and CE enable hierarchical memory mapping in multi-processor systems.
Burst operation is controlled by ADV (active-low), LBO (linear/interleaved mode), and synchronized write logic using GW, BWE, and BW1–BW4 byte enables. Power management includes asynchronous ZZ sleep mode with guaranteed data retention and sub-35 µA ISB1 standby current.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address Inputs | Synchronous address latching on rising CLK edge with ADSP/ADSC; A0–A16 used for 128K×36 mode |
| CLK | Clock Input | Primary timing reference; all synchronous operations aligned to rising edge |
| CE, CS0, CS1 | Chip Enable / Selects | Three-level decode (CE active-low, CS0 active-high, CS1 active-low) enables bank isolation in multi-SRAM systems |
| ADV | Burst Address Advance | Active-low signal that increments internal burst counter; HIGH suspends burst sequence |
| LBO | Linear/Interleaved Burst Order | Asynchronous static input: LOW = linear (00→01→10→11), HIGH = interleaved (00→01→11→10) |
| GW, BWE, BW1–BW4 | Write Control Inputs | GW enables full 36-bit writes; BWE gates byte enables; BW1–BW4 each control one 9-bit byte (I/O0–7+I/OP1, etc.) |
| OE | Output Enable | Asynchronous control of I/O drivers; LOW enables flow-through output, HIGH forces high-Z |
| ZZ | Sleep Mode | Asynchronous HIGH entry into full sleep mode; internal clock gating and <35 µA IZZ current |
| I/O0–I/O31, I/OP1–I/OP4 | Data I/O | 36-bit bidirectional synchronous data path; no output register (true flow-through) |
| VDD, VDDQ, VSS | Power/Ground | Dual-supply design: VDD powers core logic, VDDQ powers I/O buffers - minimizes switching noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| Flow-through output architecture | Zero-cycle output registration eliminates pipeline delay - critical for cache tag lookups and real-time buffering |
| Single-cycle deselect | Chip deactivation completes within one clock cycle - prevents bus contention during rapid context switches |
| Self-timed write cycle | Internal timing decision deferred until end of cycle - simplifies system timing margining and supports variable-latency buses |
| Programmable burst order (LBO) | Hardware-selectable linear or interleaved addressing - matches CPU cache line layouts (e.g., ARM vs. x86) |
| Industrial temperature range | –40°C to +85°C operation with full AC/DC specs - validated for uncontrolled ambient deployments |
| Low-power sleep mode (ZZ) | Full clock gating and <35 µA supply current - enables energy-proportional memory in always-on edge nodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C1371DV33-7BBXC | 128K × 36, 7 ns, 144-ball FBGA only; no TQFP option; requires external termination resistors | Targeted at space-constrained ATE and high-density modules where BGA is acceptable | Choose when board area is constrained and BGA assembly is available; avoid if TQFP rework or thermal cycling reliability is critical. |

FAQ
What memory organization does the 71V3577S75PFG support?
The 71V3577S75PFG supports two configurations: 128K × 36-bit (4.608 Mbit) and 256K × 18-bit (4.608 Mbit), selected via pin strapping. In 128K × 36 mode, address lines A0–A16 are used; in 256K × 18 mode, A0–A17 are active. Both deliver identical total capacity with different data bus widths to match system interface requirements.
Does the 71V3577S75PFG support both linear and interleaved burst modes?
Yes, the 71V3577S75PFG supports both burst orders via the LBO (Linear Burst Order) pin. When LBO is LOW, the device uses linear addressing (00→01→10→11); when HIGH, it uses interleaved order (00→01→11→10). This hardware-selectable feature ensures compatibility with diverse CPU cache architectures without firmware changes.
What is the significance of the flow-through output architecture in the 71V3577S75PFG?
The flow-through output architecture means the 71V3577S75PFG has no output register - data appears at the I/O pins after tCD (e.g., 7.5 ns) from the rising CLK edge, with no additional clock-cycle delay. This eliminates pipeline latency, enabling true zero-cycle-read performance essential for cache tag arrays and real-time packet inspection engines.
How does the 71V3577S75PFG handle power management in low-activity periods?
The 71V3577S75PFG implements three power states: active (IDD ≤ 255 mA), standby (ISB1 ≤ 35 mA), and full sleep (IZZ ≤ 35 µA). Sleep mode is entered asynchronously via the ZZ pin, which gates the internal clock and retains data without refresh. This allows dynamic power scaling in burst-oriented traffic patterns common in networking gear.
Is the 71V3577S75PFG pin-compatible with other devices in the 71V3577/79 family?
Yes, the 71V3577S75PFG shares identical pinout and package (100-pin TQFP) with other speed grades (e.g., 71V3577S85PFG) and the 71V3579S variants. However, 71V3579S omits BW3/BW4 pins and supports only 256K × 18 mode - so direct substitution requires verification of byte-enable usage and memory configuration in the target design.
