Product details
Overview
71V632S5PFGI from IDT is a 3.3V synchronous SRAM organized as 64K × 32 (2,097,152 bits), featuring pipelined outputs, single-cycle deselect, and burst counter logic. It supports 100 MHz operation with 5.5 ns clock access time, operates across industrial temperature range (–40°C to +85°C), and is packaged in a 100-pin TQFP for Pentium™ and PowerPC™ secondary cache applications.
For engineers reviewing the 71V632S5PFGI datasheet, 71V632S5PFGI pinout, 71V632S5PFGI application, or 71V632S5PFGI equivalent, this page delivers verified timing parameters, JEDEC-compliant TQFP package mapping, burst mode behavior under LBO control, self-timed write architecture with GW/BWE/BWx, and power-down management via ZZ input - all confirmed for the exact 71V632S5PFGI variant.
Technical Context
The 71V632S5PFGI implements a synchronous pipelined read architecture where the first output data appears one clock cycle after address presentation, followed by three additional burst words on subsequent rising edges. Its internal burst counter advances A0/A1 per cycle, with sequence order determined by LBO pin state (linear vs. interleaved).
Write operations are self-timed using global write (GW) or byte-write enable (BWE) with four independent byte write controls (BW1–BW4). Power-down is entered synchronously when ZZ = HIGH, suspending internal clocks while retaining data; recovery requires deselection before reactivation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 64K × 32 (2 Mbit); enables 32-bit wide data path for processor cache interfaces |
| Clock Access Time | 5.5 ns at 100 MHz; guarantees minimum clock-to-output delay for high-speed burst reads |
| Supply Voltage | 3.3 V ±5%; single-rail operation compatible with modern 3.3V logic families |
| Operating Temperature | –40°C to +85°C; qualified for industrial-grade embedded systems and computing modules |
| Burst Mode | Four-word pipelined burst per address; reduces bus arbitration overhead in cache line fills |
| Power-Down Control | ZZ input enables low-power sleep mode; current drops to ≤10 µA (typical) during standby |
| Package | 100-pin TQFP (14 mm × 20 mm); JEDEC-standard footprint for high-density PCB layouts |
Pinout & Package
Packaged in a JEDEC-standard 100-pin thin quad flatpack (TQFP), the 71V632S5PFGI uses a 14 mm × 20 mm body with 0.5 mm lead pitch. Pin 1 is located at top-left corner (marked dot), and pins are numbered counterclockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit address bus; selects one of 64K locations; A0/A1 drive internal burst counter |
| I/O0–I/O31 | Bi-directional Data Bus | 32-bit parallel interface; supports simultaneous read/write with byte-level granularity |
| CLK | System Clock Input | Synchronous edge-triggered reference; all operations aligned to rising edge |
| CE, CS0, CS1 | Chip/Chip Select | Three independent enables; CE active-low primary select; CS0/CS1 support multi-chip configurations |
| OE | Output Enable | Asynchronous control; places I/O bus in high-impedance state independent of CLK |
| GW, BWE, BW1–BW4 | Write Controls | Global write (GW) or byte-write (BWE + BWx) initiates self-timed write cycles per selected bytes |
| ADSP, ADSC, ADV | Address Strobe Logic | ADSP/ADSC latch address; ADV inserts wait states and suspends burst sequencing |
| LBO | Burst Order Select | Configures linear (LBO = VSS) or interleaved (LBO = VDD) burst address sequence |
| ZZ | Power-Down Enable | Active-high entry into low-power mode; retains memory contents while halting internal clocks |
| VDD / VDDQ / VSS / VSSQ | Power & Ground | VDD/VSS for core logic; VDDQ/VSSQ for I/O drivers - decoupling critical for signal integrity |
Key Features
| Feature | Design Value |
|---|---|
| Pipelined Output Architecture | Delivers first burst word one clock cycle after address; eliminates wait states in consecutive cache-line reads |
| Single-Cycle Deselect | Chip deactivation completes within one CLK period - enables rapid switching between memory banks |
| Self-Timed Write Cycle | Internal timing logic resolves write completion without external strobes; simplifies controller design |
| Byte-Write Granularity | Four independent 8-bit write lanes (BW1–BW4) allow partial-word updates without read-modify-write overhead |
| Linear/Interleaved Burst Modes | LBO pin selects burst address order - matches Pentium™ (interleaved) or PowerPC™ (linear) cache protocols |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C1332BV33-5BC | Same 64K × 32 organization, 5 ns access, but uses 119-ball BGA; no LBO pin - fixed linear burst only | Requires PCB redesign due to BGA packaging; lacks interleaved burst mode needed for Pentium™ compatibility | Select only if BGA layout is already committed and Pentium™ interface not required |
| AS7C32099B-55PCN | 64K × 32, 5.5 ns access, 100-pin TQFP, but asynchronous interface - no pipelined outputs or burst counter | Cannot support pipelined cache reads; requires external burst sequencing logic and additional timing control | Choose only for cost-sensitive non-cache applications where synchronous timing is unnecessary |
Compared with CY7C1332BV33-5BC and AS7C32099B-55PCN, the 71V632S5PFGI uniquely combines pipelined burst reads, selectable linear/interleaved addressing via LBO, and 100-pin TQFP packaging - making it irreplaceable for legacy Pentium™/PowerPC™ cache designs requiring pin- and function-level compatibility.

FAQ
What is the maximum operating frequency supported by the 71V632S5PFGI?
The 71V632S5PFGI supports up to 100 MHz operation, corresponding to a 5.5 ns clock access time. This speed grade is validated across the full industrial temperature range (–40°C to +85°C) and requires strict adherence to setup/hold timing on CLK and address inputs as specified in the AC Electrical Characteristics table.
Does the 71V632S5PFGI support both linear and interleaved burst modes?
Yes, the 71V632S5PFGI supports both burst modes via the LBO (Burst Order) pin. When LBO = VSS, it executes linear burst sequences (00→01→10→11); when LBO = VDD, it performs interleaved bursts (00→01→11→10). This dual-mode capability ensures compatibility with both PowerPC™ (linear) and Pentium™ (interleaved) processor cache protocols.
How does the single-cycle deselect feature function in the 71V632S5PFGI?
The 71V632S5PFGI achieves single-cycle deselect by completing chip disable within one CLK period upon deassertion of CE, CS0, or CS1. This allows immediate termination of ongoing burst sequences and rapid handoff to other memory devices on shared buses - critical for multi-bank cache architectures requiring low-latency arbitration.
What is the role of the ZZ pin on the 71V632S5PFGI?
The ZZ pin on the 71V632S5PFGI enables synchronous power-down mode. When ZZ = HIGH, the device enters low-power sleep, reducing ICC to ≤10 µA while retaining stored data. Recovery requires ZZ = LOW followed by a valid deselection cycle before resuming normal operation - ensuring deterministic wake-up timing.
Is the 71V632S5PFGI pin-compatible with other members of the IDT71V632 family?
Yes, the 71V632S5PFGI shares identical pinout and package (100-pin TQFP) with all speed grades in the IDT71V632 family (e.g., 71V632S6PFGI, 71V632S7PFGI). Differences are limited to AC timing parameters (tCD, tCYC); DC characteristics and functional pin behavior remain consistent across variants.
