Product details
Overview
7130LA20TFG 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, 20 ns maximum read cycle time, 2V data retention capability, and TTL-compatible 5V ±10% operation - used in real-time inter-processor communication systems requiring concurrent access without external logic.
For engineers reviewing the 7130LA20TFG datasheet, 7130LA20TFG pinout, 7130LA20TFG application, or 7130LA20TFG equivalent, key selection criteria include BUSY arbitration timing (tBAA ≤ 20 ns), battery-backed data retention at 2V, industrial temperature range (–40°C to +85°C), and compatibility with IDT7140SLAVE devices for 16-bit expansion.
Technical Context
The 7130LA20TFG implements fully asynchronous dual-port architecture with independent left/right address, control, and I/O buses. Its on-chip arbitration logic resolves port contention via BUSY flag assertion, with tAPS = 5 ns priority setup time ensuring deterministic resolution when addresses match.
As a MASTER-only device, it features open-drain BUSYL/BUSYR outputs requiring external pull-up resistors, INTL/INTR interrupt flags for cross-port signaling, and automatic power-down controlled by CEL/CER - enabling ultra-low standby current (1 µA typical in full CMOS standby mode).
Key Specifications

|---|---|
| Memory Size | 1K × 8 bits (1024 words × 8-bit wide), supporting independent read/write per port |
| Access Time | 20 ns max read cycle time (tRC), enabling 50 MHz sustained throughput per port |
| Data Retention | 2.0 V minimum VCC for data retention - supports battery backup operation without system power |

| Operating Temp | –40°C to +85°C (industrial grade), qualified per MIL-PRF-38535 QML for reliability-critical use |
| Standby Current | 1 µA typical (ISB3, CMOS-level inputs), 1 mA typical (ISB1, TTL-level inputs) - enables low-power embedded operation |
| Package | 64-pin STQFP (PPG64), 10 mm × 10 mm × 1.4 mm body, lead-free and RoHS-compliant |
Pinout & Package
64-pin STQFP (PPG64) package with 0.5 mm pitch, thermally enhanced exposed pad, and dual-row perimeter I/O layout optimized for signal integrity in high-speed memory interfaces.
| 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; tri-stated when OEL = VIH or CEL = VIH |
| I/O0R–I/O7R | Right port bidirectional data | 8-bit data path; tri-stated when OER = VIH or CER = VIH |
| CEL / CER | Chip enable (left/right) | Active-low enables port access and disables internal circuitry for standby current reduction |
| OEL / OER | Output enable (left/right) | Active-low controls I/O drivers; high-Z when deasserted, regardless of CE state |
| R/WL / R/WR | Read/write control (left/right) | High = read, low = write; determines direction of data flow on respective I/O bus |
| BUSYL / BUSYR | Arbitration status (open-drain) | Low = port write inhibited due to address conflict; requires external 4.7 kΩ pull-up to VCC |
| INTL / INTR | Interrupt request (open-drain) | Low-active flags for inter-port event signaling; requires external pull-up |
| VCC / GND | Power supply | Multiple VCC (pins 33, 48, 55, 56) and GND (pins 32, 47, 63, 64) pins for low-noise decoupling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C131-25JC | 25 ns access, 5V only, no data retention below 4.5V, PLCC-52 package | Lacks 2V retention and open-drain BUSY; requires external arbitration logic for MASTER/SLAVE | Choose for cost-sensitive commercial designs where battery backup is unnecessary and PCB space allows PLCC |
| AS7C31026B-20TIN | 20 ns access, 3.3V supply, LVCMOS interface, TQFP-48 package | Not pin-compatible; incompatible voltage and signaling - requires level shifters and layout redesign | Choose only for new 3.3V systems prioritizing lower power over legacy 5V interoperability |
Compared with CY7C131-25JC and AS7C31026B-20TIN, the 7130LA20TFG uniquely delivers 20 ns performance with true 2V data retention, industrial temperature rating, and integrated arbitration - making it irreplaceable in battery-backed, safety-critical dual-processor architectures without redesign.

FAQ
What is the guaranteed data retention voltage for the 7130LA20TFG?
The 7130LA20TFG guarantees data retention down to 2.0 V VCC, as specified in Table 7 of the official datasheet. This enables reliable battery backup operation during main power failure. The 7130LA20TFG must be operated within its industrial temperature range (–40°C to +85°C) for this specification to hold, and retention current is limited to 4000 µA maximum at 25°C ambient.
Does the 7130LA20TFG support MASTER/SLAVE configuration with IDT7140 devices?
Yes, the 7130LA20TFG is explicitly designed as the MASTER device in a MASTER/SLAVE dual-port SRAM architecture with IDT7140 SLAVE devices. It provides on-chip arbitration logic, BUSY output flags, and INTL interrupt generation - allowing seamless 16-bit or wider memory expansion without external logic. The 7130LA20TFG's BUSYL/BUSYR outputs connect directly to the corresponding BUSY inputs of IDT7140 devices.
What is the meaning of "TFG" in the 7130LA20TFG part number?
The "TFG" suffix in 7130LA20TFG denotes the package and screening: "T" = STQFP (64-pin thin quad flatpack), "F" = industrial temperature range (–40°C to +85°C), and "G" = lead-free/RoHS-compliant construction. This matches the PPG64 package code referenced in the datasheet's pin configuration diagrams and ordering information.
Can the 7130LA20TFG operate with only one port enabled while the other remains in standby?
Yes, the 7130LA20TFG supports asymmetric power management: when CEL = VIH and CER = VIL, the left port enters ISB2 standby (50 µA typical), while the right port remains fully operational. This feature reduces total system current in applications where traffic is unidirectional or bursty, and is confirmed in Table 6a under ISB2 test conditions for LA versions.
Are BUSYL and BUSYR pins on the 7130LA20TFG push-pull or open-drain outputs?
BUSYL and BUSYR on the 7130LA20TFG are open-drain outputs, as explicitly stated in Note 1 of the Functional Block Diagram and Truth Table I. They require external pull-up resistors (typically 4.7 kΩ to VCC) to assert HIGH. This design enables wired-OR arbitration across multiple dual-port devices - a requirement for scalable multi-master memory systems.
