Product details
Overview
7130SA25TF8 from IDT is a high-speed 1K × 8 dual-port static RAM configured as a MASTER device with on-chip arbitration logic, 25ns maximum access time, TTL-compatible 5V ±10% supply, and industrial temperature range (–40°C to +85°C). It enables full-speed 16-bit-or-wider memory expansion when paired with IDT7140 SLAVE devices in real-time control systems requiring concurrent read/write access.
For engineers reviewing the 7130SA25TF8 datasheet, 7130SA25TF8 pinout, 7130SA25TF8 application, or 7130SA25TF8 equivalent, key selection criteria include BUSY output flag behavior, port-to-port interrupt signaling (INTL/INTR), arbitration priority setup timing (tAPS = 5ns), and compatibility with 48-pin TQFP packaging for space-constrained embedded designs.
Technical Context
The 7130SA25TF8 implements fully asynchronous dual-port operation with independent left/right address, control, and I/O buses - allowing simultaneous access without external logic. Its on-chip arbitration logic resolves contention via BUSY flag assertion, with tBAA/tBAC ≤ 20ns and tBDD ≤ 35ns for 25ns-grade timing.
As a MASTER-only device, it features open-drain BUSYL/BUSYR outputs requiring external pull-ups, INTL/INTR flags for inter-port communication, and no BUSY input functionality - distinguishing it functionally and electrically from SLAVE IDT7140 variants.
Key Specifications

Pinout & Package
7130SA25TF8 is supplied in a 48-pin Thin Quad Flat Package (TQFP) with 0.5mm pitch, body size 10mm × 10mm × 1.4mm (PPG64) or 14mm × 14mm × 1.4mm (PNG64), RoHS-compliant and green-part qualified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 24, 25, 48) | Ground reference | Four dedicated ground pins minimize ground bounce during simultaneous port switching |
| VCC (Pins 23, 26) | Power supply | Dual VCC pins reduce IR drop and improve noise immunity across high-speed I/O banks |

| BUSYL / BUSYR | Arbitration status (open-drain) | Indicates write contention on respective port; requires external 4.7kΩ pull-up for proper logic level |
| INTL / INTR | Interrupt flag (push-pull) | Signals inter-port events (e.g., address 3FF writes) to host controller without polling overhead |
| A0L–A9L / A0R–A9R | Address inputs (left/right) | 10-bit addressing per port supports full 1K memory map access with no external decoding |
| I/O0L–I/O7L / I/O0R–I/O7R | Data I/O (bidirectional, left/right) | True dual-port data paths enable zero-cycle handoff between processors or DMA engines |
Key Features

Applications
| Real-Time Motion Control | Digital Signal Processing Buffer |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C1354V25 | 3.3V core supply, 25ns access, 1K × 16 organization - requires external byte-enable logic for 8-bit alignment | Targets modern low-voltage systems; lacks native 8-bit dual-port configuration and BUSY arbitration | Choose when migrating to 3.3V infrastructure and accepting added logic complexity |
| IDT7140SA25TF8 | SLAVE-only variant: BUSY inputs (not outputs), no on-chip arbitration, identical speed/package | Must be used with 7130SA25TF8 in MASTER/SLAVE pairs; cannot operate stand-alone as memory controller | Required companion for 16-bit+ bus expansion; not a functional substitute for standalone MASTER use |
Compared with CY7C1354V25 and IDT7140SA25TF8, the 7130SA25TF8 uniquely delivers self-contained arbitration, 5V TTL compatibility, and stand-alone MASTER operation - making it irreplaceable in legacy industrial systems where voltage migration or external logic addition is prohibited.

FAQ
What is the exact memory organization and bus width of the 7130SA25TF8?
The 7130SA25TF8 implements a 1K × 8-bit (1024 words × 8-bit) dual-port SRAM with fully independent left and right data buses (I/O0L–I/O7L and I/O0R–I/O7R), each supporting bidirectional 8-bit transfers. It does not support 16-bit or wider native word widths - expansion to 16-bit requires pairing with an IDT7140 SLAVE device using MASTER/SLAVE architecture. The 7130SA25TF8 itself operates exclusively as a MASTER with on-chip arbitration logic.
Does the 7130SA25TF8 support battery backup or data retention below 5V?
No, the 7130SA25TF8 does not support battery backup or low-voltage data retention. That capability is exclusive to LA-suffix variants (e.g., 7130LA25TF8), which guarantee data retention down to 2.0V. The SA suffix denotes standard active power consumption (550mW typ.) and operation strictly within 4.5V–5.5V supply range. Using the 7130SA25TF8 below 4.5V risks undefined behavior and data loss.
How does BUSY arbitration work on the 7130SA25TF8, and what external components are required?
The 7130SA25TF8 provides open-drain BUSYL and BUSYR outputs that must be pulled up to VCC via external 4.7kΩ resistors. When both ports attempt writes to the same address, the device asserts the relevant BUSY line low after tBAA ≤ 20ns, blocking the later-arriving write until the line deasserts. This hardware arbitration prevents memory corruption without software intervention. The 7130SA25TF8 does not accept BUSY as an input - that function belongs only to SLAVE IDT7140 devices.
Can the 7130SA25TF8 operate in commercial or military temperature ranges?
The 7130SA25TF8 is specifically rated for industrial temperature range (–40°C to +85°C), as confirmed by its "SA" suffix and datasheet Table 3. Commercial-grade (0°C to +70°C) versions exist under different part numbers (e.g., 7130SA20J), and military-grade (–55°C to +125°C) variants carry "M" or QML-38535 compliance markings. Substituting the 7130SA25TF8 into commercial or military designs violates its qualified operating envelope and voids parametric guarantees.
What package type and pin count does the 7130SA25TF8 use, and is it RoHS compliant?
The 7130SA25TF8 uses a 48-pin Thin Quad Flat Package (TQFP) with two footprint options: PPG64 (10mm × 10mm) and PNG64 (14mm × 14mm), both 1.4mm height and 0.5mm lead pitch. It is RoHS-compliant and qualifies as a green part per IDT's ordering information. The "TF8" suffix explicitly denotes this TQFP packaging - distinct from DIP, LCC, PLCC, or ceramic flatpack variants offered in the same speed grade.
