Product details
Overview
7130SA20TF8 from IDT is a high-speed 1K × 8 dual-port static RAM configured as a MASTER device with on-chip arbitration logic, 20 ns maximum read cycle time, TTL-compatible 5 V ±10% supply, and industrial temperature range (–40°C to +85°C). It enables full-speed 16-bit-or-wider memory systems when paired with IDT7140 SLAVE devices in real-time digital signal processing and military avionics data buffering.
For engineers reviewing the 7130SA20TF8 datasheet, 7130SA20TF8 pinout, 7130SA20TF8 application, or 7130SA20TF8 equivalent, this page delivers verified timing parameters, dual-port arbitration behavior, BUSY/INT flag operation, package-specific DC/AC characteristics, and validated alternative part selection guidance for embedded memory subsystem design.
Technical Context
The 7130SA20TF8 implements fully asynchronous dual-port access with independent left/right address, control, and I/O buses. Its on-chip arbitration logic resolves port contention via BUSY flag assertion, with tBAA/tBDA ≤20 ns and tAPS = 5 ns priority setup time - enabling deterministic conflict resolution without external logic.
As a MASTER-only device, it features open-drain BUSYL/BUSYR outputs requiring pull-up resistors, INTL/INTR flags for inter-port signaling, and CE-controlled power-down modes yielding ISB1 ≤30 mA (TTL-level standby) and ISB3 ≤1.0 mA (CMOS-level full standby) at 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1K × 8 bits (1024 words × 8-bit wide), supporting independent concurrent reads/writes on left and right ports |
| Access Time | 20 ns max read cycle time (tRC), enabling 50 MHz sustained dual-port throughput in synchronous systems |
| Supply Voltage | 5.0 V ±10% (4.5–5.5 V), compatible with legacy TTL logic families and industrial 5 V rails |
| Operating Temp | –40°C to +85°C (industrial grade), qualified per MIL-PRF-38535 QML for ruggedized applications |
| Power Consumption | Active ICC = 110 mA typ., standby ISB1 = 30 mA typ., full CMOS standby ISB3 = 1.0 mA typ. - critical for low-duty-cycle monitoring systems |
| Arbitration Logic | On-chip port arbitration with BUSY output flag and 5 ns arbitration priority setup (tAPS), eliminating need for discrete glue logic |
| Interface Type | TTL-compatible inputs/outputs; open-drain BUSY pins require external pull-ups; no internal voltage translation |
Pinout & Package
7130SA20TF8 is supplied in a 64-pin STQFP (Small Thin Quad Flat Package) with 10 mm × 10 mm body and 1.4 mm height, pin-compatible with TQFP variants but optimized for thermal performance in dense PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 33, 47) | Ground reference | Two dedicated ground pins reduce ground bounce during simultaneous dual-port transitions |
| VCC (Pins 17, 18) | Power supply | Dual VCC pins ensure stable core voltage delivery under high-current switching conditions |
| CEL / CER | Chip enable (left/right) | Independent chip select enables selective port activation - essential for power-gated subsystems |
| OEL / OER | Output enable (left/right) | Controls tri-state of I/O bus; allows shared data bus operation without contention |
| R/WL / R/WR | Read/write control (left/right) | Active-high write mode; supports R/W-controlled or CE-controlled write cycles per AC table |
| BUSYL / BUSYR | Arbitration status (open-drain) | Asserted low during port contention; requires external pull-up resistor per datasheet Note 1 |
| INTL / INTR | Interrupt flag (open-drain) | Signals inter-port events (e.g., address match at 3FF/3FE); also requires pull-up |
| A0L–A9L / A0R–A9R | Address inputs (left/right) | 10-bit addressing per port; supports full 1K memory map independently on each side |
| I/O0L–I/O7L / I/O0R–I/O7R | Data I/O (bidirectional, left/right) | 8-bit parallel data path per port; high-impedance when OE inactive or CE deasserted |
Key Features
| Feature | Design Value |
|---|---|
| MASTER-only arbitration | Enables seamless 16-bit+ expansion with IDT7140 SLAVE without external arbitration logic or timing margin penalties |
| 20 ns access speed | Supports real-time DSP buffer applications where sub-25 ns latency is required between acquisition and processing stages |
| Open-drain BUSY/INT | Allows wired-OR interrupt aggregation across multiple dual-port SRAMs in multi-processor architectures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C133-25JC | 25 ns access time; 5 V only; no built-in arbitration logic - requires external BUSY management | Lacks on-chip arbitration; suitable only when external logic handles port contention | Select when cost sensitivity outweighs board space constraints and arbitration complexity is acceptable |
| AS7C31025B-20TIN | 20 ns access; 3.3 V supply; no BUSY/INT signals; asynchronous dual-port only | Requires level-shifting for 5 V systems; no hardware arbitration or inter-port signaling | Choose for new 3.3 V designs where inter-port coordination is handled entirely in firmware |
Compared with CY7C133-25JC and AS7C31025B-20TIN, the 7130SA20TF8 uniquely integrates arbitration logic and open-drain BUSY/INT flags in a 5 V industrial package - delivering hardware-enforced coherency without external components or voltage translation.

FAQ
What is the maximum operating temperature range for the 7130SA20TF8?
The 7130SA20TF8 is rated for industrial temperature operation from –40°C to +85°C, validated per MIL-PRF-38535 QML requirements. This range is confirmed in Table 3 of the datasheet and applies to all SA-speed grades in STQFP packaging. The 7130SA20TF8 does not support commercial (0°C to +70°C) or military (–55°C to +125°C) ranges - its qualification is strictly industrial grade.
Does the 7130SA20TF8 include on-chip arbitration logic?
Yes, the 7130SA20TF8 includes dedicated on-chip arbitration logic, distinguishing it from SLAVE devices like the IDT7140. This logic asserts BUSYL/BUSYR outputs during port contention and enforces priority via tAPS = 5 ns setup time. The 7130SA20TF8 datasheet explicitly states "On-chip port arbitration logic (IDT7130 Only)" in the Features section and confirms BUSY output behavior in Notes 1 and 2 of the Functional Block Diagram.
What package type is used for the 7130SA20TF8?
7130SA20TF8 uses a 64-pin STQFP (Small Thin Quad Flat Package) with 10 mm × 10 mm body and 1.4 mm height, as specified in the Pin Configurations section (Drawing 05) and ordering information. The "TF8" suffix in the part number directly denotes this STQFP variant - distinct from DIP, LCC, PLCC, or ceramic flatpack options available for other members of the 7130SA/LA family.
Can the 7130SA20TF8 operate with a 3.3 V supply?
No, the 7130SA20TF8 requires a 5.0 V ±10% supply (4.5–5.5 V) and is not rated for 3.3 V operation. The Recommended DC Operating Conditions table specifies VCC min/max as 4.5 V/5.5 V, and VIH/VIL thresholds are defined relative to 5 V logic levels. Attempting 3.3 V operation will result in undefined timing, increased ICC, and potential functional failure - confirmed across Tables 02, 04, and 06a/b.
How does the BUSY arbitration work on the 7130SA20TF8?
On the 7130SA20TF8, BUSY arbitration activates when both ports attempt access to the same memory location. The device asserts BUSYL or BUSYR (open-drain, requires pull-up) to block writes on the lower-priority port, with tBAA/tBDA ≤20 ns and tAPS = 5 ns ensuring deterministic resolution. Truth Table III and Waveforms 12–15 confirm that BUSY is driven low only during address matches, and the 7130SA20TF8 never asserts both BUSYL and BUSYR simultaneously.
