Product details
Overview
7130SA35PFI 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, 35ns maximum access time, industrial temperature range (–40°C to +85°C), and TTL-compatible 5V ±10% operation. 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 7130SA35PFI datasheet, 7130SA35PFI pinout, 7130SA35PFI application, or 7130SA35PFI equivalent, key selection criteria include BUSY flag timing (tBAA ≤ 35ns), port-to-port arbitration priority setup (tAPS = 5ns), dual independent asynchronous access, open-drain BUSY output requiring pullup, and compatibility with 48-pin plastic DIP (PDG48) packaging.
Technical Context
The 7130SA35PFI implements fully asynchronous dual-port architecture with separate address, data, and control lines for left (L) and right (R) ports - enabling concurrent read/write operations without external logic. Its on-chip arbitration logic resolves contention via BUSY flag assertion when both ports access the same address, with tBDD ≤ 35ns ensuring deterministic resolution.
As a MASTER-only device, it features open-drain BUSYL/BUSYR outputs (requiring external pullups), INTL/INTR interrupt flags for inter-port signaling, and supports battery-backed data retention only in LA variants - not applicable to this SA-grade part. It operates exclusively at 5V ±10% with no low-voltage or multi-supply capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1K × 8 bits (1024 words × 8-bit data width per port) |
| Access Time | 35ns max - defines minimum read cycle time for timing-critical real-time control loops |
| Operating Voltage | 5.0V ±10% - requires single TTL-compatible supply; no 3.3V or mixed-voltage support |
| Temperature Range | –40°C to +85°C - qualified for industrial environments including motor drives and PLCs |
| Active Current | 110mA typ. (both ports active) - determines thermal design and power rail sizing |
| Standby Current | 25mA typ. (TTL-level CE high) - impacts low-power idle mode in always-on systems |
| Package | 48-pin PDG48 plastic DIP - through-hole mounting; 0.61″ × 0.55″ footprint |
Pinout & Package
48-pin plastic DIP (PDG48) package with 0.61″ × 0.55″ body size and 0.3″ row spacing. All VCC pins (pins 24, 25, 48) must be decoupled to GND; all GND pins (pins 1, 23, 26) require low-impedance grounding.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (1,23,26) | Ground reference | Common return path for both ports; multiple pins reduce ground bounce in high-speed switching |
| VCC (24,25,48) | Power supply | 5V ±10% supply; three pins ensure adequate current delivery and noise margin |
| CEL / CER | Chip enable (left/right) | Active-low enables respective port; deassertion places port in standby (ISB1/ISB2) |
| OEL / OER | Output enable (left/right) | Active-low controls I/O drivers; high-Z state prevents bus contention during shared data bus use |
| R/WL / R/WR | Read/write control (left/right) | High = read, low = write; asynchronous operation allows independent port modes |
| BUSYL / BUSYR | Arbitration flag (open-drain) | Outputs LOW during address contention; requires external 4.7kΩ pullup to VCC per pin |
| INTL / INTR | Interrupt flag (open-drain) | Signals inter-port events (e.g., flag set/reset); also requires external pullup |
| A0L–A9L / A0R–A9R | Address inputs (left/right) | 10-bit address buses - support full 1K address space per port independently |
| I/O0L–I/O7L / I/O0R–I/O7R | Data I/O (left/right) | Bidirectional 8-bit data paths; high-impedance when OE high or CE high |
Key Features
| Feature | Design Value |
|---|---|
| On-chip arbitration logic | Eliminates need for external glue logic in MASTER/SLAVE memory expansion architectures |
| Open-drain BUSY and INT outputs | Enables wired-OR interrupt and arbitration signaling across multiple dual-port devices |
| Independent asynchronous port operation | Allows simultaneous CPU and DSP access to shared memory without clock domain synchronization |
| TTL-compatible interface | Direct connection to legacy 5V microcontrollers, FPGAs, and ASICs without level-shifting |
| Industrial temperature qualification | Validated operation from –40°C to +85°C - suitable for factory automation and transportation electronics |
Applications
| Motor Control System | Digital Signal Processor Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C024AV-35AXC | 3.3V core, 5V-tolerant I/O; 35ns access; 1K × 16 organization | Requires level translation for 5V systems; wider data bus reduces chip count in 16-bit designs | Select when migrating to lower-power 3.3V systems or needing native 16-bit width |
| IDT7140SA35PFI | SLAVE-only variant; BUSY inputs (not outputs); no on-chip arbitration logic | Must be paired with 7130SA35PFI in MASTER/SLAVE configuration; no standalone use | Select only as companion to 7130SA35PFI for 16-bit memory expansion |
Compared with CY7C024AV-35AXC and IDT7140SA35PFI, the 7130SA35PFI uniquely provides MASTER arbitration logic and 5V-native operation - making it irreplaceable in legacy industrial controllers requiring drop-in 5V dual-port memory with built-in conflict resolution.

FAQ
What is the maximum operating temperature range for the 7130SA35PFI?
The 7130SA35PFI is rated for industrial temperature operation from –40°C to +85°C. This specification is validated per the manufacturer's recommended operating conditions table and applies across the full 35ns access speed grade. It does not support military (–55°C to +125°C) or commercial (0°C to +70°C) ranges - only the industrial grade.
Does the 7130SA35PFI support battery backup data retention?
No, the 7130SA35PFI does not support battery backup data retention. That feature is exclusive to LA-suffixed variants (e.g., 7130LA35PFI), which specify VDR = 2.0V minimum and ICCDR ≤ 4000µA at 2V. The "SA" suffix denotes standard active power characteristics only, with no data retention capability below 4.5V.
How many VCC and GND pins does the 7130SA35PFI have in its PDG48 package?
The 7130SA35PFI in the 48-pin PDG48 plastic DIP package has three VCC pins (pins 24, 25, and 48) and three GND pins (pins 1, 23, and 26). This multi-pin power/ground distribution reduces impedance and improves noise immunity for high-speed dual-port operation.
Is the 7130SA35PFI pin-compatible with the IDT7140SA35PFI?
No, the 7130SA35PFI is not pin-compatible with the IDT7140SA35PFI. Although both share the same 48-pin PDG48 footprint, their pin functions differ significantly: 7130SA35PFI has BUSYL/BUSYR as open-drain outputs, while IDT7140SA35PFI has them as inputs. INTL/INTR are outputs on 7130SA35PFI but unused (N/C) on IDT7140SA35PFI.
What external components are required for proper operation of the 7130SA35PFI BUSY and INT pins?
The BUSYL, BUSYR, INTL, and INTR pins on the 7130SA35PFI are open-drain outputs and require external pullup resistors to VCC. A 4.7kΩ resistor per pin is recommended per the manufacturer's functional block diagram notes and absolute maximum ratings guidance to ensure valid HIGH levels and reliable arbitration/interrupt signaling.
