Product details
Overview
7130SA35PF from IDT (Integrated Device Technology) is a high-speed 1K × 8 dual-port static RAM configured as a MASTER device with on-chip arbitration logic, 35 ns maximum access time, TTL-compatible 5V ±10% supply, and industrial temperature range (–40°C to +85°C). It enables error-free 16-bit-or-wider memory expansion when paired with IDT7140 SLAVE devices in real-time embedded control systems.
For engineers reviewing the 7130SA35PF datasheet, 7130SA35PF pinout, 7130SA35PF application, or 7130SA35PF equivalent, this page delivers verified timing parameters (tAA = 35 ns, tRC = 35 ns), BUSY/INT arbitration behavior, dual-port I/O isolation, power modes (ISB1 = 25 mA max), and FP48 ceramic flatpack mechanical data - all critical for deterministic memory coherency in multi-processor designs.
Technical Context
The 7130SA35PF implements fully asynchronous dual-port operation with independent left/right address, control, and data buses. Its on-chip arbitration logic resolves port contention via BUSY flag assertion (open-drain, requires pull-up), with tBDD ≤ 35 ns and tAPS = 5 ns priority setup.
It supports MASTER-only functions: BUSY output (not input), INTL/INTR interrupt signaling for inter-port communication, and automatic power-down via CE-driven ISB1/ISB2/ISB3/ISB4 states. No battery backup - LA variant only provides 2V data retention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1K × 8 bits (1024 words × 8-bit wide), enabling compact dual-access buffer storage |
| Access Time (max) | 35 ns - guarantees deterministic read latency for real-time control loops |
| Supply Voltage | 5.0 V ±10% - compatible with legacy TTL logic families without level shifting |
| Operating Temp | –40°C to +85°C - qualified for industrial environments including motor drives and PLCs |
| Standby Current | 25 mA max (ISB1, both ports disabled) - enables low-power sleep in battery-backed systems |
| Package | 48-pin ceramic flatpack (FP48) - hermetic, high-reliability packaging for harsh environments |
| Arbitration Logic | On-chip BUSY generation with tAPS = 5 ns - eliminates external glue logic for port conflict resolution |
Pinout & Package
48-pin ceramic flatpack (FP48), body size ≈ 0.75 in × 0.75 in × 0.11 in, hermetically sealed, leadless, surface-mount compatible with reflow profiles per MIL-STD-202.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0L–A9L | Left port address inputs | 10-bit address bus for left-side memory access (0x000–0x3FF) |
| A0R–A9R | Right port address inputs | 10-bit address bus for right-side memory access (0x000–0x3FF) |
| I/O0L–I/O7L | Left port bidirectional data | 8-bit data path; high-impedance when OEL = VIH or CEL = VIH |
| I/O0R–I/O7R | Right port bidirectional data | 8-bit data path; high-impedance when OER = VIH or CER = VIH |
| CEL / CER | Chip enable (left/right) | Active-low enables port; controls ISB1/ISB2 standby current states |
| OEL / OER | Output enable (left/right) | Active-low enables data output drivers; disables outputs when high |
| R/WL / R/WR | Read/write control (left/right) | High = read, low = write; determines direction of I/O bus transceivers |
| BUSYL / BUSYR | BUSY flag (left/right output) | Open-drain outputs indicating port contention; require external pull-up resistors |
| INTL / INTR | Interrupt flag (left/right output) | Active-low flags for inter-port event signaling (e.g., write completion) |
| VCC / GND | Power / ground | All VCC pins must be connected; all GND pins must be connected - no floating supplies |
Key Features
| Feature | Design Value |
|---|---|
| On-chip arbitration logic | Resolves simultaneous access conflicts without external logic; tAPS = 5 ns ensures deterministic priority |
| Dual independent asynchronous ports | Full read/write concurrency - left and right ports operate at full speed without synchronization overhead |
| Open-drain BUSY outputs | Enables wired-OR arbitration across multiple MASTER devices; requires external 4.7kΩ pull-up |
| Port-to-port interrupt signaling | INTL/INTR flags support handshake protocols (e.g., producer-consumer buffering) with tINS ≤ 25 ns |
| TTL-compatible interface | Direct connection to 5V microcontrollers, FPGAs, and ASICs without level translators |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C131-35PC | 35 ns access, 5V, 1K × 8, but no on-chip arbitration logic; BUSY must be implemented externally | Requires discrete logic for port conflict resolution; increases BOM count and layout complexity | Select when arbitration is handled at system level and cost-per-pin is prioritized over integration |
| IDT7140SA35PF | Same package and timing, but SLAVE-only: BUSY pins are inputs (not outputs); no arbitration logic | Cannot operate standalone; must be paired with 7130SA35PF as MASTER in 16-bit+ configurations | Select only as companion SLAVE in MASTER/SLAVE memory expansion - not a functional substitute |
Compared with CY7C131-35PC and IDT7140SA35PF, the 7130SA35PF uniquely integrates arbitration, eliminating external logic while supporting autonomous MASTER operation - critical for space-constrained, high-reliability industrial systems where signal integrity and deterministic latency are non-negotiable.

FAQ
What is the maximum operating temperature range for the 7130SA35PF?
The 7130SA35PF is rated for industrial temperature operation from –40°C to +85°C. This range is confirmed in the "Recommended Operating Temperature and Supply Voltage" table (2689 tbl 03) and applies to all SA-speed variants in FP48, LCC, and DIP packages. It does not support military-grade –55°C to +125°C operation - that requires the MIL-PRF-38535 QML-certified 7130MA variant.
Does the 7130SA35PF support battery backup data retention?
No, the 7130SA35PF does not support battery backup data retention. That feature is exclusive to the LA variant (e.g., 7130LA35PF), which specifies VDR = 2.0 V and ICCDR ≤ 4000 µA under data retention conditions. The "SA" suffix denotes standard active power consumption (550 mW typ.) without low-voltage retention circuitry.
How is port arbitration implemented in the 7130SA35PF?
The 7130SA35PF implements hardware arbitration via open-drain BUSYL and BUSYR outputs. When address/contention is detected, the device asserts BUSY on the losing port within tBAA ≤ 35 ns. The winning port continues operation; the losing port's write is internally inhibited. tAPS = 5 ns ensures priority resolution, and no external logic is required - a key differentiator from generic dual-port SRAMs.
What package type is used by the 7130SA35PF?
7130SA35PF uses a 48-pin ceramic flatpack (FP48), as explicitly stated in the "Pin Configurations" section (2689 drw 03F) and noted in footnote 3: "FP48 package body is approximately .75 in x .75 in x .11 in." This hermetic, leadless package meets MIL-STD-883 requirements and is distinct from PLCC, TQFP, or DIP variants of the same family.
Can the 7130SA35PF be used as a standalone memory without a SLAVE device?
Yes, the 7130SA35PF functions fully as a standalone 8-bit dual-port SRAM. Its MASTER capability - including on-chip arbitration, BUSY output, and INT signaling - is operational without any SLAVE device. The SLAVE (IDT7140) is optional and only required when expanding to 16-bit or wider data paths; it does not affect basic 7130SA35PF functionality.
