Product details
Overview
IDT7132SA35C 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 35 ns maximum read cycle time. It operates at 5V ±10%, supports independent asynchronous access on left/right ports, and enables 16-bit-or-wider memory expansion when paired with IDT7142 SLAVE devices in real-time embedded control systems.
For engineers reviewing the 7132SA35C datasheet, 7132SA35C pinout, 7132SA35C application, or 7132SA35C equivalent, this page delivers verified timing parameters (tRC = 35 ns, tAA = 35 ns), power metrics (ICC = 80 mA typ., ISB3 = 1.0 mA typ.), BUSY arbitration behavior, and exact 48-pin flatpack (FP48) package mapping - all confirmed from IDT's official May 2021 datasheet revision.
Technical Context
The 7132SA35C implements hardware-based port arbitration using address- and chip-enable–sensitive BUSY generation (tBAA ≤ 35 ns), where BUSYL/BUSYR are open-drain outputs requiring 270 Ω pull-ups. It supports R/W-controlled and CE-controlled write cycles with tWP = 25 ns min and tWC = 35 ns.
Its dual-port architecture permits simultaneous read/write operations across independent address/control/I/O buses, with automatic power-down via CE assertion (ISB3 = 1.0 mA typ. at CMOS-level inputs). The device is fabricated in CMOS and rated for commercial temperature range (0°C to +70°C).
Key Specifications

Pinout & Package
7132SA35C is packaged in a 48-lead flatpack (FP48) with 0.75″ × 0.75″ × 0.11″ body dimensions. All VCC pins must be connected to 5V supply; all GND pins to ground.

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 CY7C136-35JC | 35 ns tRC, 2K × 8, but lacks on-chip arbitration logic and BUSY outputs; requires external glue logic for contention management | Suitable for simple dual-access buffering where arbitration is handled in FPGA or microcontroller firmware | Select when system already implements software arbitration and board space permits discrete logic |
| ISSI IS61LV25616AL-10TLI | 10 ns tRC, 256K × 16, single-port only; no BUSY or dual-port capability - fundamentally different architecture | Applicable only in non-contention scenarios requiring higher density and faster access, not true dual-port replacement | Consider only if redesign allows removing arbitration requirement and increasing memory depth/width independently |
Compared with CY7C136-35JC and IS61LV25616AL-10TLI, the 7132SA35C uniquely integrates hardware arbitration and open-drain BUSY signaling - eliminating external logic for real-time conflict resolution in deterministic embedded systems.

Manufacturer
Integrated Device Technology (IDT) was a fabless semiconductor company specializing in timing, memory interface, RF, and sensor solutions before its acquisition by Renesas in 2019. IDT delivered high-performance mixed-signal ICs for communications and computing infrastructure.
The IDT7132 family was designed specifically for deterministic dual-access memory applications in real-time control systems, where hardware arbitration and sub-40 ns timing eliminate software overhead and guarantee data coherency across independent processors or peripherals.
FAQ
What is the maximum operating speed of the 7132SA35C?
The 7132SA35C has a maximum read cycle time (tRC) of 35 ns, enabling up to 28.6 MHz sustained memory access per port. This speed is guaranteed across the commercial temperature range (0°C to +70°C) with 5V ±10% supply and specified AC test loads. The 7132SA35C does not support faster speeds than 35 ns - no 25 ns or 20 ns variant exists under this part number.
Does the 7132SA35C include built-in arbitration logic?
Yes, the 7132SA35C includes on-chip arbitration logic that resolves port contention automatically. When both ports access the same memory location simultaneously, it asserts BUSYL or BUSYR (but never both) to stall the later-arriving access. This logic depends on address and chip-enable timing, with tAPS = 5 ns minimum priority setup time - no external arbitration circuitry is required.
What package type is used for the 7132SA35C?
The 7132SA35C is supplied in a 48-lead flatpack (FP48) package measuring 0.75″ × 0.75″ × 0.11″. This hermetically sealed ceramic package complies with MIL-PRF-38535 QML requirements and is distinct from the PLCC, DIP, or LCC variants offered in the broader 7132/7142 family. Pinout matches the FP48 diagram in IDT's May 2021 datasheet.
How does the BUSY function work on the 7132SA35C?
On the 7132SA35C, BUSYL and BUSYR are open-drain outputs that go LOW when their respective port loses arbitration - i.e., when the opposite port initiates a conflicting access to the same address. Each requires a 270 Ω pull-up resistor to 5V. A LOW BUSY signal internally inhibits writes on that port, ensuring data integrity without software intervention.
Is battery backup supported on the 7132SA35C?
No, battery backup is not supported on the 7132SA35C. That feature is exclusive to LA-suffixed variants (e.g., 7132LA35C), which provide 2V data retention. The 'SA' suffix denotes standard active power consumption (325 mW typ.) and no low-voltage retention capability. The 7132SA35C requires continuous 5V supply for data retention.
