Product details
Overview
7130SA20TF from IDT 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, TTL-compatible 5 V ±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 control systems.
For engineers reviewing the 7130SA20TF datasheet, 7130SA20TF pinout, 7130SA20TF application, or 7130SA20TF equivalent, key selection criteria include BUSY output flag timing (tBAA ≤ 20 ns), dual-port asynchronous access independence, master arbitration capability, and compatibility with 48-pin flatpack (FP48) packaging for legacy military/industrial PCB layouts.
Technical Context
The 7130SA20TF implements fully asynchronous dual-port operation with separate address, data, and control buses for left and right ports. 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.
It features open-drain BUSYL/BUSYR outputs requiring external pull-up resistors, supports R/W-controlled and CE-controlled write cycles, and provides INTL/INTR flags for inter-port communication - all while maintaining independent active/standby power states per port (ISB1 = 30 mA typ. at 5 V).

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C1354V25 | 3.3 V core, 25 ns access, 1K × 18 organization, QCC56 package | Requires level-shifting for 5 V systems; wider data bus suits FPGA-based designs | Select when migrating to 3.3 V infrastructure or needing 18-bit word width |
| AS7C31025B | 5 V, 25 ns access, single-port only, 32-pin SOJ package | No arbitration or BUSY logic; requires external semaphore management | Select only for cost-sensitive, non-contention use cases with software-managed access |
Compared with CY7C1354V25 and AS7C31025B, the 7130SA20TF uniquely delivers 5 V TTL compatibility, on-chip arbitration, and 20 ns speed in a hermetically sealed flatpack - making it irreplaceable for legacy military/industrial dual-processor systems requiring guaranteed hardware-enforced coherency.

FAQ
What is the maximum operating temperature range for the 7130SA20TF?
The 7130SA20TF is rated for industrial temperature operation from –40°C to +85°C, verified per manufacturer specifications and qualified for use in embedded control systems deployed in uncontrolled environmental enclosures. This range is explicitly defined in the Recommended Operating Temperature table and applies to all AC/DC electrical characteristics unless otherwise noted.
Does the 7130SA20TF support battery backup data retention?
No, the 7130SA20TF does not support battery backup data retention. That feature is exclusive to LA-suffixed variants (e.g., 7130LA20TF), which specify VDR = 2.0 V minimum and ICCDR ≤ 4000 µA at 2 V. The "SA" suffix denotes standard active power profile without retention mode.
How many ground and power pins does the 7130SA20TF have in its FP48 package?
The 7130SA20TF in the 48-pin ceramic flatpack (FP48) has four GND pins (pins 1, 24, 25, 48) and two VCC pins (pins 23, 47), as confirmed in the Pin Configurations section and Absolute Maximum Ratings table. This dual-VCC/dual-ground layout minimizes supply noise coupling between port domains.
Is the 7130SA20TF pin-compatible with the IDT7140 series?
No, the 7130SA20TF is not pin-compatible with IDT7140 devices. While both share functional similarity as dual-port SRAMs, the 7130SA20TF is a MASTER device with BUSY outputs and arbitration logic, whereas IDT7140 is a SLAVE with BUSY inputs. Their pinouts differ significantly - e.g., BUSYL/BUSYR are outputs on 7130SA20TF but inputs on IDT7140 - and cannot be substituted without PCB redesign.
What is the purpose of the INTL and INTR pins on the 7130SA20TF?
The INTL and INTR pins on the 7130SA20TF are open-drain interrupt flags used for port-to-port signaling. Writing to specific addresses (e.g., 0x3FF on left port sets INTR on right port) generates hardware interrupts, enabling event-driven synchronization between independent processors without polling. These signals require external pull-up resistors per datasheet Note 2.
