Product details
Overview
71V3576S133PFG8 from IDT is a 128K × 36-bit, 3.3V synchronous SRAM with pipelined outputs, burst counter, and single-cycle deselect. It operates at 133MHz (4.2ns clock access time), supports linear/interleaved burst modes via LBO input, and features global/byte write control (GW/BWE/BW1–BW4) for precise memory management in high-speed cache or buffer applications.
For engineers reviewing the 71V3576S133PFG8 datasheet, 71V3576S133PFG8 pinout, 71V3576S133PFG8 application, or 71V3576S133PFG8 equivalent, this device delivers deterministic timing for pipelined read/write bursts, low-latency deselect, and industrial-grade reliability in TQFP-100 packaging - critical for networking packet buffers, FPGA co-processor caches, and real-time DSP subsystems.
Technical Context
The 71V3576S133PFG8 implements a synchronous architecture with registered address, data, and control inputs triggered on the rising edge of CLK. Its internal burst counter advances on ADV=LOW and selects sequence order (linear or interleaved) based on static LBO state - no runtime reconfiguration.
Burst operation delivers four consecutive 36-bit words per address cycle, with first-word output pipelined by one clock cycle. Write cycles are self-timed and support global (GW), byte-select (BW1–BW4), or combined (BWE + BWx) modes - all synchronized to CLK and gated by CE/CS0/CS1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 128K × 36-bit (4.608 Mbit); fixed configuration for this part number |
| Clock Frequency | 133 MHz - enables 7.5 ns minimum clock cycle time for deterministic system timing |
| Access Time | 4.2 ns clock-to-data (tCD) - guarantees pipelined output validity within one clock after rising edge |
| Supply Voltages | VDD = 3.3 V ±5% (core), VDDQ = 3.3 V ±5% (I/O) - separate rails allow I/O voltage stability during core switching |
| Operating Temperature | 0°C to +70°C (Commercial grade) - validated for stable operation across full range without derating |
| Power Consumption | 250 mA IDD (133 MHz, commercial) - enables thermal budgeting in dense PCB layouts |
| Package | JEDEC-standard 100-pin TQFP (14 mm × 20 mm) - surface-mount compatible with standard reflow profiles |
Pinout & Package
Packaged in a JEDEC-standard 100-pin plastic thin quad flatpack (TQFP), 14 mm × 20 mm body size, with 0.5 mm lead pitch. Pin 1 marked by corner cut; top-side marking includes "71V3576" and date code.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address Inputs | Synchronous address register inputs; A0–A16 used for 128K×36 mode (17-bit addressing) |
| CLK | Clock Input | Rising-edge-triggered master timing reference for all synchronous operations |
| CE, CS0, CS1 | Chip Enable / Selects | Three-level decode (CE LOW + CS0 HIGH + CS1 LOW) enables device; allows bank selection in multi-SRAM systems |
| GW, BWE, BW1–BW4 | Write Control Inputs | GW writes all 36 bits; BWE enables byte-write logic; BW1–BW4 select 9-bit bytes (I/O0–7+I/OP1, etc.) |
| ADV, ADSP, ADSC | Burst & Address Status | ADV advances burst counter; ADSP/ADSC load address register - dual-source support for processor/cache controller |
| LBO | Burst Order Select | Static input: LBO=LOW → linear burst; LBO=HIGH → interleaved burst - sets sequence before operation begins |
| ZZ | Sleep Mode Input | Asynchronous HIGH entry to full sleep mode; reduces supply current to ≤35 mA (IZZ) while retaining data |
| I/O0–I/O31, I/OP1–I/OP4 | Data I/O | 36-bit bidirectional bus; registered inputs/outputs synchronized to CLK; I/OP pins are parity bits |
| VDD, VDDQ, VSS | Power/Ground | VDD (core), VDDQ (I/O), and VSS (common ground) - require separate decoupling per JEDEC guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Pipelined Burst Outputs | First data word appears on next rising CLK edge; subsequent words follow on successive edges - eliminates wait states in burst transfers |
| Single-Cycle Deselect | Device enters high-impedance state within one clock cycle after chip disable - prevents bus contention during rapid bank switching |
| Self-Timed Write Cycle | Internal timing logic completes write without external strobes; supports GW, BWE, or BWx activation - simplifies controller interface |
| Linear/Interleaved Burst Modes | LBO pin statically configures burst address sequence (A0/A1 progression) - matches cache line mapping requirements of x86 or PowerPC processors |
| 3.3V Core + I/O Separation | Dual 3.3V supplies (VDD/VDDQ) enable independent noise filtering and reduce crosstalk between core logic and data bus drivers |
| Industrial-Grade Option Available | Same pinout and timing as commercial version but qualified from –40°C to +85°C - supports extended-temperature embedded deployments |
Applications
| Networking Packet Buffer | FPGA Co-Processor Cache |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 71V3576S133PFGI8 | Identical electrical specs and pinout; rated for –40°C to +85°C industrial temperature range | Required for deployment in outdoor telecom cabinets or factory-floor automation where ambient exceeds 70°C | Select when extended temperature qualification is mandatory; same layout and firmware compatibility |
| 71V3578S133PFG8 | 256K × 18-bit organization (same density, different width); shares 100-pin TQFP package and timing | Better suited for 16/18-bit bus architectures (e.g., older DSPs) where 36-bit width creates unnecessary routing complexity | Choose for narrower data paths; requires address decoding adjustment due to 18-bit word addressing |
Compared with 71V3576S133PFG8, the industrial-grade 71V3576S133PFGI8 offers identical performance with extended thermal resilience, while the 71V3578S133PFG8 provides equivalent density in an 18-bit-wide format - enabling optimized bus utilization in legacy 16-bit systems without sacrificing speed or burst capability.

FAQ
What is the memory organization of the 71V3576S133PFG8?
The 71V3576S133PFG8 is organized as 128K × 36 bits (4.608 Mbit), meaning it provides 131,072 words of 36-bit data. This configuration is fixed for the 71V3576 family and differs from the 256K × 18-bit layout of the pin-compatible 71V3578 series. Address lines A0–A16 are active in this mode.
Does the 71V3576S133PFG8 support both linear and interleaved burst modes?
Yes, the 71V3576S133PFG8 supports both burst modes via the LBO (Linear Burst Order) input pin. When LBO is driven LOW, the device uses linear burst addressing; when HIGH, it uses interleaved burst. LBO is a static input and must remain stable during operation - it is not sampled dynamically.
What is the function of the ADV pin on the 71V3576S133PFG8?
The ADV (Burst Address Advance) pin controls burst counter progression on the 71V3576S133PFG8. When ADV is LOW, the internal burst counter increments after each cycle, delivering the next sequential or interleaved address. When ADV is HIGH, burst advancement halts - enabling burst suspension or single-word access within a burst sequence.
How does the 71V3576S133PFG8 handle power-down and sleep modes?
The 71V3576S133PFG8 supports two low-power states: standby (via CE/CS deactivation) and full sleep mode (via ZZ HIGH). In sleep mode, internal clocks are gated and supply current drops to ≤35 mA (IZZ), while data retention is guaranteed. Recovery time (tZZR) is 100 ns, and ZZ pulse width (tZZPW) must exceed that minimum.
Is the 71V3576S133PFG8 pin-compatible with other devices in the same family?
Yes, the 71V3576S133PFG8 is pin-compatible with other speed grades (e.g., 150 MHz) and temperature variants (e.g., 71V3576S133PFGI8) in the same 100-pin TQFP package. It is also mechanically and electrically compatible with the 71V3578 series, though memory organization (128K×36 vs. 256K×18) requires firmware and address decoding adjustments.
