Product details
Overview
7130LA20PFG from IDT (Integrated Device Technology) is a high-speed 1K × 8 dual-port static RAM with master arbitration logic, 20 ns maximum access time, 5 V ±10% supply, and battery-backed data retention down to 2 V - used in real-time inter-processor communication systems requiring concurrent read/write access without external logic.
For engineers reviewing the 7130LA20PFG datasheet, 7130LA20PFG pinout, 7130LA20PFG application, or 7130LA20PFG equivalent, key selection criteria include dual-port arbitration timing (tBAA ≤ 20 ns), low standby current (ISB3 = 0.2 mA typ.), open-drain BUSY flag behavior, and compatibility with IDT7140LA slave devices in 16-bit memory expansion.
Technical Context
The 7130LA20PFG implements fully asynchronous dual-port operation with independent left/right address, control, and I/O buses. Its on-chip arbitration logic resolves port contention via BUSY output assertion and supports interrupt-driven inter-port signaling using INTL/INTR flags.
It features TTL-compatible inputs, open-drain BUSY outputs requiring external pull-ups, and automatic power-down controlled by CE/CER. The LA variant enables data retention at 2 V with ICCDR ≤ 4000 µA (military grade) or ≤ 1500 µA (commercial grade).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1K × 8 bits (1024 words × 8-bit wide), enabling compact buffer or register-file applications |
| Access Time | 20 ns max (commercial grade), defining minimum cycle time for deterministic real-time response |
| Supply Voltage | 5.0 V ±10%, compatible with legacy 5 V TTL/CMOS system rails without level-shifting |
| Standby Current | 0.2 mA typical (ISB3, CMOS-level inputs), enabling ultra-low-power hold mode during idle periods |
| Data Retention | 2.0 V minimum VCC, allowing backup from coin-cell or supercapacitor during main power loss |
| Operating Temp | –40°C to +85°C (industrial grade), validated for embedded control and instrumentation environments |
| Package | 64-pin STQFP (PPG64), 10 mm × 10 mm footprint with exposed thermal pad for thermal management |
Pinout & Package
7130LA20PFG is housed in a 64-pin STQFP (PPG64) package with 0.5 mm pitch, 10 mm × 10 mm body, and exposed thermal pad. Pin functions are electrically symmetric across left/right ports but physically assigned to dedicated pins per side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0L–A9L | Left port address inputs | 10-bit address bus for left-side memory access (0x000–0x3FF) |
| I/O0L–I/O7L | Left port bidirectional data | 8-bit data path supporting concurrent read/write with right port |
| CEL, OEL, R/WL | Left port control signals | Chip Enable, Output Enable, Read/Write select - fully asynchronous timing |
| BUSYL, INTL | Left port open-drain flags | BUSYL asserts low during port contention; INTL sets interrupt on right port write to address 0x3FF |
| A0R–A9R | Right port address inputs | Independent 10-bit address space, enabling true dual-access concurrency |
| I/O0R–I/O7R | Right port bidirectional data | Electrically isolated from left I/Os - no bus contention risk |
| CER, OER, R/WR | Right port control signals | Functionally identical to left controls but with separate timing domains |
| BUSYR, INTR | Right port open-drain flags | BUSYR mirrors BUSYL behavior; INTR responds to left port writes to 0x3FF |
| VCC, GND | Power and ground | Multiple VCC/GND pins distributed for low-noise operation and EMI reduction |
Key Features

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-20AXC | 2K × 16 organization, 3.3 V core, no battery retention, integrated BUSY arbitration | Requires voltage translation in 5 V systems; larger density but incompatible pinout and power domain | Select when migrating to 3.3 V architecture and needing higher density without external retention circuitry |
| IDT7140LA20PFG | Slave-only device, no on-chip arbitration, BUSY inputs only, identical timing and retention | Cannot operate standalone; must be paired with 7130LA as master in 16-bit expansion configurations | Select only as companion to 7130LA20PFG in widened memory systems - not a functional replacement |
Compared with CY7C024AV-20AXC and IDT7140LA20PFG, the 7130LA20PFG uniquely combines standalone master arbitration, 5 V compatibility, and 2 V data retention - making it irreplaceable in legacy industrial controllers requiring drop-in upgrade paths and brown-out resilience.

FAQ
What is the maximum operating temperature range for the 7130LA20PFG?
The 7130LA20PFG is rated for industrial temperature operation from –40°C to +85°C, verified per manufacturer specifications and qualified for use in harsh embedded environments including factory automation and transportation systems. This range applies to all speed grades of the LA variant, including the 20 ns version.
Does the 7130LA20PFG support true simultaneous read/write operations on both ports?
Yes, the 7130LA20PFG supports fully asynchronous, concurrent read and write operations on left and right ports. However, if both ports access the same memory location simultaneously, on-chip arbitration asserts BUSYL or BUSYR to inhibit the later-arriving write - ensuring data integrity without external logic. The 7130LA20PFG implements this via tAPS (5 ns setup) and tBDD timing.
How does the BUSY signal behave on the 7130LA20PFG during port contention?
On the 7130LA20PFG, BUSYL and BUSYR are open-drain outputs requiring external pull-up resistors. During address match contention, the port with earlier stable address/enable asserts its BUSY line low within tBAA ≤ 20 ns, blocking writes on the contending port until the BUSY line deasserts after tBDC. The 7130LA20PFG guarantees that only one BUSY output goes low per contention event.
Can the 7130LA20PFG retain data when main power drops below 5 V?
Yes, the 7130LA20PFG supports battery-backed data retention down to 2.0 V VCC, drawing ≤1500 µA (commercial) or ≤4000 µA (military) in retention mode. This allows seamless operation during brown-out events or controlled shutdowns when backed by a coin cell or supercapacitor - a feature absent in SA variants and most competing dual-port SRAMs.
Is the 7130LA20PFG pin-compatible with other members of the IDT7130/7140 family?
The 7130LA20PFG shares identical pinout and package (64-pin STQFP) with all other 7130X20 variants (e.g., 7130SA20PFG) and matches the 7140LA20PFG in physical layout - but differs functionally as a master device with arbitration logic and BUSY outputs. Pin compatibility enables footprint reuse across speed and power variants, though electrical behavior (e.g., BUSY vs. BUSY input) must be verified per design.
