Product details
Overview
IDT7132LA70JI/2703 from Integrated Device Technology (IDT) is a high-speed 2K × 8 dual-port static RAM configured as a MASTER device with on-chip arbitration logic, BUSY output flag, and battery-backed data retention at 2V. It operates at 70 ns max access time, consumes 1 mW standby power, and supports independent asynchronous read/write on left/right ports in industrial temperature range (–40°C to +85°C). It is used in real-time embedded systems requiring concurrent memory access, such as digital signal processors interfacing with host controllers.
For engineers reviewing the IDT7132LA70JI/2703 datasheet, IDT7132LA70JI/2703 pinout, IDT7132LA70JI/2703 application, or IDT7132LA70JI/2703 equivalent, key selection criteria include verified 70 ns tAA/tACE timing, open-drain BUSY output requiring 270 Ω pull-up, dual-port arbitration behavior under address contention, and LA-series 2V data retention capability - all confirmed for this exact flatpack variant.
Technical Context
The IDT7132LA70JI/2703 implements hardware-based port arbitration using address and chip enable signals - not R/W state - to assert BUSYL/BUSYR outputs when both ports access the same memory location. Its master-only arbitration logic resolves contention by granting priority based on input timing margins (tAPS = 5 ns min), ensuring deterministic write inhibition on the delayed port.
It features separate control paths per port (CEL/OEL/R/WL and CER/OER/R/WR), TTL-compatible 5V ±10% supply, and automatic power-down via CE-driven ISB3 current (0.2 mA typ. at full CMOS standby). The LA version enables battery backup operation with guaranteed 2.0 V data retention voltage and ≤4 µA ICCDR at 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 2K × 8 bits (2048 words × 8-bit wide), dual independent ports |
| Access Time (tAA / tACE) | 70 ns max - defines minimum clock-to-data delay for synchronous interface design |
| Standby Current (ISB3) | 0.2 mA typical - enables ultra-low-power battery backup mode with 2V VCC |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard TTL logic rails and industrial 5V systems |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded control and instrumentation |
| BUSY Output Type | Open-drain (BUSYL/BUSYR) - requires external 270 Ω pull-up per pin for proper arbitration signaling |
| Data Retention Voltage | 2.0 V minimum - guarantees nonvolatile data hold during main power loss or brownout |
Pinout & Package
Package: 48-lead flatpack (FP48), body size ≈ 0.75 in × 0.75 in × 0.11 in, hermetically sealed for industrial reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 24) | Ground reference | Must be connected to system ground plane; two dedicated pins reduce ground bounce in high-speed dual-port operation |
| VCC (Pin 25) | Power supply | 5V ±10% supply input; single VCC pin shared across both ports simplifies power routing |
| CEL / CER | Chip Enable (Left/Right) | Active-low enables respective port; controls ISB1/ISB2/ISB3 standby modes and arbitration activation |
| OEL / OER | Output Enable (Left/Right) | Active-low enables I/O drivers; high-Z state prevents bus contention during port switching |
| R/WL / R/WR | Read/Write Control (Left/Right) | Active-low writes data; high reads - determines direction of data flow on bidirectional I/O lines |
| BUSYL / BUSYR | Arbitration Flag (Master only) | Open-drain outputs indicating address contention; require 270 Ω pull-up to VCC per datasheet note |
| A0L–A10L / A0R–A10R | Address Inputs (Left/Right) | 11-bit address buses (2048 locations); matched propagation delays ensure synchronized arbitration |
| I/O0L–I/O7L / I/O0R–I/O7R | Data I/O (Left/Right) | Bidirectional 8-bit data paths; internally isolated to prevent cross-port leakage during simultaneous access |
Key Features
| Feature | Design Value |
|---|---|
| On-chip arbitration logic | Resolves dual-port address contention without external logic; guarantees deterministic priority via tAPS timing |
| 2V data retention (LA version) | Enables seamless battery backup with <4 µA retention current - critical for power-fail-safe applications |
| Independent port control | Separate CE/OE/RW per port allows asymmetric operation - e.g., one port reading while other writes |
| Low-power standby (1 mW) | Reduces thermal load in dense memory arrays; supports deep-sleep modes in portable instrumentation |
| TTL-compatible 5V interface | Eliminates level-shifting requirements in legacy industrial control systems using standard 5V logic families |
Applications
| Digital Signal Processor (DSP) Memory Interface | Real-Time Industrial Controller |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Cypress CY7C1371D-100AXC | 100 ns access, 3.3V core, no built-in arbitration logic - requires external BUSY management | Lacks master/slave arbitration; suitable only where software-controlled serialization is acceptable | Select only if migrating to 3.3V systems and adding external arbitration logic is feasible |
| ISSI IS61LV25616AL-10TLI | 10 ns faster (60 ns), but no BUSY arbitration or 2V retention - single-port architecture | Requires external dual-port controller IC or FPGA logic to emulate contention handling | Choose only for cost-sensitive designs where arbitration is implemented in FPGA fabric |
Compared with IDT7132LA70JI/2703, the Cypress part trades arbitration capability for lower voltage operation, while the ISSI part sacrifices hardware arbitration and battery retention for raw speed - neither offers the integrated master/slave arbitration and 2V data hold that define the IDT7132LA's role in fault-tolerant embedded systems.

FAQ
What is the maximum access time specification for IDT7132LA70JI/2703?
The IDT7132LA70JI/2703 has a maximum access time of 70 ns for both address access (tAA) and chip enable access (tACE), as specified in the commercial and industrial speed grades. This value is measured under standard conditions: VCC = 5.0 V ±10%, TA = +25°C, and load per Figure 1 (775 Ω, 5 pF). The 70 ns rating applies directly to this FP48 flatpack variant and is production-tested per IDT datasheet 2692 tbl 08a.
Does IDT7132LA70JI/2703 support battery backup operation?
Yes, IDT7132LA70JI/2703 supports battery backup operation with guaranteed data retention at VCC = 2.0 V, as confirmed in the LA-series specification table (2692 tbl 06). It draws ≤4 µA in data retention mode (ICCDR) at +25°C, enabling long-term storage during main power loss. This feature is exclusive to LA versions and is not available in SA variants.
How must the BUSY pins be connected on IDT7132LA70JI/2703?
The BUSYL and BUSYR pins on IDT7132LA70JI/2703 are open-drain outputs requiring external 270 Ω pull-up resistors to VCC, as explicitly stated in datasheet Notes 1 and 2 and Figure 3. Failure to install these resistors will prevent proper arbitration signaling. Each BUSY pin must have its own dedicated pull-up; shared pull-ups may cause timing skew or false contention detection.
Is IDT7132LA70JI/2703 pin-compatible with IDT7142LA70JI/2703?
No, IDT7132LA70JI/2703 is not pin-compatible with IDT7142LA70JI/2703. While both share the same 48-pin flatpack footprint, their BUSY pin functions differ fundamentally: IDT7132LA70JI/2703 has BUSYL/BUSYR as open-drain outputs, whereas IDT7142LA70JI/2703 uses them as inputs. Swapping them without redesigning the BUSY routing will cause functional failure.
What is the industrial temperature range qualification for IDT7132LA70JI/2703?
IDT7132LA70JI/2703 is qualified for the industrial temperature range of –40°C to +85°C, as documented in the "Recommended Operating Temperature" table (2692 tbl 02) and confirmed in the ordering information notes. This rating applies specifically to LA-series devices in FP48 packaging and is validated across all DC and AC electrical parameters in that range.
