Product details
Overview
7130SA25TF from IDT is a high-speed 1K × 8 dual-port static RAM configured as a MASTER device with on-chip arbitration logic, 25 ns maximum read cycle time (tRC), TTL-compatible 5V ±10% supply, and industrial temperature range (–40°C to +85°C). It enables full-speed 16-bit-or-wider memory expansion when paired with IDT7140 SLAVE devices in real-time embedded control systems.
For engineers reviewing the 7130SA25TF datasheet, 7130SA25TF pinout, 7130SA25TF application, or 7130SA25TF equivalent, this page delivers verified timing parameters, port arbitration behavior, BUSY/INT flag operation, and package-specific DC/AC electrical characteristics - all confirmed for the 7130SA25TF variant in TQFP-64 packaging.
Technical Context
The 7130SA25TF implements fully asynchronous dual-port access with independent left/right address, control, and I/O buses. Its on-chip arbitration logic resolves simultaneous access contention via BUSY flag assertion, with tBDD ≤35 ns and tAPS = 5 ns minimum priority setup time.
It supports R/W-controlled and CE-controlled write cycles, features open-drain BUSY outputs requiring external pull-ups, and provides INTL/INTR flags for inter-port communication. Data retention is not supported (LA version only retains at 2V; SA variant lacks battery backup).
Key Specifications

Pinout & Package
64-pin Thin Quad Flat Package (TQFP), body size 14 mm × 14 mm × 1.4 mm, lead pitch 0.8 mm, RoHS-compliant green variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 33, 49) | Ground reference | Two dedicated ground pins reduce ground bounce and improve noise immunity across both ports |
| VCC (Pins 32, 48) | Power supply | Dual VCC pins ensure stable core voltage delivery under high-current switching conditions |
| CEL / CER | Chip enable (left/right) | Independent enables allow selective port activation - critical for low-power partitioned memory access |
| OEL / OER | Output enable (left/right) | Controls I/O bus directionality; high-Z state prevents bus contention during multi-port sharing |
| R/WL / R/WR | Read/write control (left/right) | Asynchronous R/W signaling enables true concurrent read/write operations across ports |
| BUSYL / BUSYR | Arbitration status (open-drain) | Indicates port contention; requires external 4.7kΩ pull-up to VCC for proper logic-level generation |
| INTL / INTR | Interrupt flag (open-drain) | Signals inter-port events (e.g., flag set/clear); must be pulled up externally for interrupt controller interfacing |
| A0L–A9L / A0R–A9R | Address inputs (left/right) | 10-bit addressing per port supports full 1K memory map without external address decoding |
| I/O0L–I/O7L / I/O0R–I/O7R | Data I/O (bidirectional, left/right) | True bidirectional data paths eliminate need for external transceivers in shared-bus architectures |
Key Features
| Feature | Design Value |
|---|---|
| On-chip arbitration logic | Resolves simultaneous left/right port access without external logic - eliminates timing-critical discrete arbitration circuits |
| Open-drain BUSY/INT outputs | Enables wired-OR interrupt and BUSY signaling across multiple dual-port RAMs in daisy-chained configurations |
| Master-only BUSY flag generation | 7130SA25TF asserts BUSY on contested addresses; 7140 acts as slave with BUSY input - defines strict MASTER/SLAVE hierarchy |
| Full asynchronous operation | Eliminates clock distribution requirements - simplifies integration into mixed-signal or legacy microcontroller systems |
| TTL-compatible I/O levels | Direct interface with 5V microcontrollers, FPGAs, and ASICs without level-shifting components |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C1362BV25 | 3.3V core supply, 25 ns tRC, 5V-tolerant I/O; no built-in arbitration logic | Requires external priority encoder for contention resolution; unsuitable for MASTER/SLAVE expansion topology | Select only if migrating to 3.3V system architecture and adding discrete arbitration logic |
| IDT7142S25YG | Same 1K×8 dual-port architecture, but SLAVE-only; lacks BUSY output and arbitration logic | Cannot operate standalone; must be paired with 7130-series MASTER; no INT flag support | Use exclusively as companion SLAVE in 16-bit+ memory expansions with 7130SA25TF |
Compared with CY7C1362BV25 and IDT7142S25YG, the 7130SA25TF uniquely integrates arbitration logic and MASTER-specific BUSY/INT signaling - enabling drop-in replacement in legacy IDT-based systems while eliminating external glue logic required by alternatives.

FAQ
What is the maximum operating frequency supported by the 7130SA25TF?
The 7130SA25TF has a maximum read cycle time (tRC) of 25 ns, supporting effective operation up to 40 MHz in systems where address and control signals meet timing constraints. This value is guaranteed across the full industrial temperature range (–40°C to +85°C) and 4.5–5.5 V supply, as specified in Table 09a of the official IDT datasheet for 7130SA25TF.
Does the 7130SA25TF support battery backup or data retention below 5V?
No, the 7130SA25TF does not support battery backup or low-voltage data retention. Only LA-suffix variants (e.g., 7130LA25TF) guarantee 2.0 V data retention. The SA suffix denotes standard active power profile without retention capability - confirmed by absence of VDR and ICCDR specifications in 7130SA25TF AC/DC characterization tables.
How are BUSY and INT pins implemented on the 7130SA25TF?
BUSYL, BUSYR, INTL, and INTR are open-drain outputs on the 7130SA25TF and require external pull-up resistors (typically 4.7 kΩ to VCC). BUSY signals indicate port contention during simultaneous access; INT flags signal inter-port events like flag set/clear - both follow TTL voltage thresholds and are electrically identical per datasheet Figures 3 and 16.
Can the 7130SA25TF be used as a standalone dual-port RAM without a SLAVE device?
Yes, the 7130SA25TF functions as a complete standalone 1K × 8 dual-port SRAM. Its on-chip arbitration logic, BUSY outputs, and full port independence enable autonomous operation. The SLAVE pairing (e.g., with 7140) is optional and only required for data bus expansion beyond 8 bits - explicitly stated in IDT's functional description for 7130SA25TF.
Which package variant does the 7130SA25TF use, and what are its key mechanical dimensions?
The 7130SA25TF uses the PNG64 package: a 64-pin TQFP with 14 mm × 14 mm body size and 1.4 mm height, 0.8 mm lead pitch. This matches the "PNG64(4)" designation in IDT's Pin Configuration drawings (Document 2689 drw 05), and is distinct from STQFP (PPG64) and PLCC variants.
