Product details
Overview
7130LA100PDG from IDT is a high-speed 1K × 8 dual-port static RAM configured as a MASTER device with on-chip arbitration logic, 100ns maximum read/write cycle time, 1μA full-standby current (CMOS-level CE), and battery-backed data retention at 2V - used in real-time interprocessor communication systems requiring concurrent access without external logic.
For engineers reviewing the 7130LA100PDG datasheet, 7130LA100PDG pinout, 7130LA100PDG application, or 7130LA100PDG equivalent, key selection criteria include BUSY arbitration timing (tBDD ≤ 65ns), dual-port I/O isolation, 2V data retention capability, and compatibility with IDT7140SLAVE devices in 16-bit memory expansion.
Technical Context
The 7130LA100PDG implements fully asynchronous dual-port operation with independent left/right address, control, and data buses. Its on-chip arbitration logic resolves port contention via BUSYL/BUSYR open-drain outputs, requiring external pull-up resistors per datasheet Note 1.
It supports R/W-controlled and CE-controlled write cycles, features INTL/INTR interrupt flags for port-to-port signaling, and enters data retention mode when VCC drops to 2.0V with CE held high - validated only for LA-grade versions per Table 07.
Key Specifications

|---|---|
| Memory Size | 1K × 8 bits (1024 words × 8-bit wide), enabling compact dual-access buffer storage |
| Access Time | 100ns max (tAA, tACE, tAOE), defining worst-case latency for deterministic real-time response |
| Standby Current | 1μA (ISB3, CMOS-level CE), enabling ultra-low-power hold during system sleep modes |
| Data Retention | 2.0V minimum VCC, supporting backup from coin-cell or supercapacitor during main power loss |
| Supply Voltage | 4.5V–5.5V (±10% of 5V), compatible with standard TTL logic rails and industrial 5V systems |
| Operating Temp | −40°C to +85°C (industrial grade), qualified for embedded control and avionics subsystems |
| Package | 48-pin plastic DIP (PDG48), through-hole mounting with 0.61″ × 0.55″ footprint and 0.19″ height |
Pinout & Package
48-pin plastic DIP (PDG48) package with dual-row through-hole leads, 0.61″ × 0.55″ body size, and 0.3″ row spacing per datasheet Note 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1, 24) | Ground reference | Two dedicated ground pins ensure low-impedance return paths for both ports' I/O and core logic |
| VCC (Pin 23) | Power supply | Single 5V supply powers all internal circuitry; all VCC pins must be decoupled locally |
| CEL / CER | Chip enable (left/right) | Active-low enables respective port; controls dynamic/standby current states (ISB1–ISB4) |
| OEL / OER | Output enable (left/right) | Active-low enables I/O drivers; high-Z state prevents bus contention during idle |
| R/WL / R/WR | Read/write direction (left/right) | High = read, low = write; determines data flow direction on bidirectional I/O lines |
| BUSYL / BUSYR | Arbitration flag (open-drain) | Indicates port contention; requires external pull-up; blocks writes when asserted low |
| INTL / INTR | Interrupt flag (open-drain) | Signals inter-port events (e.g., address match at 3FF/3FE); requires pull-up for logic-H level |
| A0L–A9L / A0R–A9R | Address inputs (left/right) | 10-bit address buses select one of 1024 memory locations independently per port |
| I/O0L–I/O7L / I/O0R–I/O7R | Bidirectional data (left/right) | 8-bit parallel data paths; tri-stated when OE high or CE high |
Key Features
| Feature | Design Value |
|---|---|
| On-chip arbitration logic | Resolves simultaneous access conflicts without external glue logic, reducing BOM count and PCB area |
| 2V data retention (LA only) | Preserves memory contents during brown-out or controlled power-down, eliminating need for external backup controller |
| Open-drain BUSY/INT outputs | Enable wired-OR interrupt or arbitration busing across multiple dual-port devices on shared control lines |
| Master/Slave expandability | 7130LA100PDG acts as MASTER; pairs with IDT7140SLAVE to build 16-bit+ word-width systems at full speed |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C131-100JC | 1K × 8, 100ns, 5V, but no built-in arbitration logic; requires external BUSY management | Lacks on-chip port arbitration; needs discrete logic or FPGA glue for contention resolution | Select when cost sensitivity outweighs design simplicity; verify external arbitration meets tAPS ≥ 5ns |
| IDT7140LA100PDG | Same 100ns speed and LA retention, but SLAVE-only; no BUSY output or arbitration logic | Designed only for expansion with 7130 MASTER; cannot operate standalone as memory controller | Use only in paired MASTER/SLAVE configurations; not a functional substitute for 7130LA100PDG |
Compared with CY7C131-100JC and IDT7140LA100PDG, the 7130LA100PDG uniquely integrates arbitration and interrupt logic, enabling true standalone dual-processor interfacing without external components - critical for space-constrained or safety-certified designs.

FAQ
What is the data retention voltage specification for the 7130LA100PDG?
The 7130LA100PDG supports data retention down to 2.0V (VDR), verified per Table 07. This allows memory contents to be preserved during brown-out conditions or when backed by a 2V battery source. The feature is exclusive to LA-grade variants and is not available in SA versions. Operation below 2.0V risks data loss, and retention current (ICCDR) is specified up to 4000µA for military/industrial grades.
Does the 7130LA100PDG require external pull-up resistors on BUSY and INT pins?
Yes, the 7130LA100PDG requires external pull-up resistors on BUSYL, BUSYR, INTL, and INTR pins because they are open-drain outputs (per datasheet Notes 1 and 2). Typical values range from 4.7kΩ to 10kΩ to +5V. Failure to install pull-ups will prevent proper assertion of BUSY during contention or generation of valid interrupt signals to connected processors.
Can the 7130LA100PDG operate as a standalone dual-port memory without a companion SLAVE device?
Yes, the 7130LA100PDG functions fully as a standalone 1K × 8 dual-port SRAM. Its MASTER designation indicates it contains on-chip arbitration logic and BUSY outputs - unlike SLAVE-only IDT7140 devices. It does not require pairing with a 7140 to operate; the MASTER/SLAVE architecture is optional for memory expansion beyond 8 bits.
What is the meaning of "PDG" in the part number 7130LA100PDG?
"PDG" denotes the 48-pin plastic DIP package per IDT's ordering nomenclature (datasheet Pin Configurations section, Note 3). PDG48 specifies a through-hole dual-in-line package with 0.61″ × 0.55″ body dimensions and 0.19″ height. It is distinct from FP48 (flatpack), LC48 (LCC), PLG52 (PLCC), or PPG64/PNG64 (TQFP/STQFP) variants.
How does arbitration work between the left and right ports of the 7130LA100PDG?
Arbitration in the 7130LA100PDG uses on-chip logic that monitors address and control timing between ports. If both ports attempt access to the same address within the arbitration priority setup window (tAPS ≥ 5ns), the port with earlier stable inputs asserts its BUSY signal low, blocking writes on the delayed port. BUSYL and BUSYR are open-drain outputs requiring pull-ups; they cannot both be low simultaneously per Truth Table III.
