Product details
Overview
7130SA20PF 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, TTL-compatible 5V ±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 embedded control systems.
For engineers reviewing the 7130SA20PF datasheet, 7130SA20PF pinout, 7130SA20PF application, or 7130SA20PF equivalent, this page delivers verified timing parameters, port arbitration behavior, BUSY/INT flag operation, dual-port power-down modes, and package-specific DC/AC electrical characteristics - all confirmed for the FP48 ceramic flatpack variant.
Technical Context
The 7130SA20PF implements fully asynchronous dual-port access with independent left/right address, data, and control buses. Its on-chip arbitration logic resolves contention via BUSY output assertion (open-drain, requires pull-up) and supports port-to-port interrupt signaling through INTL/INTR flags.
It operates in three power states: active (typ. 110 mA), standby with TTL-level CE (typ. 30 mA), and full CMOS-level standby (typ. 1.0 mA). Data retention at 2V is not supported - that feature applies only to LA variants, not SA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 1K × 8 bits (1024 words × 8-bit wide), dual-access architecture |
| Max Read Cycle Time | 20 ns - defines minimum clock period for synchronous interface or maximum burst rate in async systems |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5V TTL logic families without level translation |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded applications |
| Active Current (ICC) | 110 mA typ. - determines thermal design and regulator sizing for continuous dual-port operation |
| BUSY Output Type | Open-drain - requires external pull-up resistor to VCC for proper flag assertion |
| Interrupt Flags | INTL (left port) and INTR (right port) - enable hardware-synchronized inter-port communication |
Pinout & Package
7130SA20PF is supplied in a 48-pin ceramic flatpack (FP48) package measuring approximately 0.75 in × 0.75 in × 0.11 in, with side-brazed leads and hermetic sealing suitable for high-reliability industrial environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 24, 25, 48) | Ground reference | All four pins must be connected to system ground plane for noise immunity and stable operation |
| VCC (Pins 23, 26) | Power supply | Both pins require low-inductance connection to 5V ±10% supply; decoupling capacitors mandatory |
| CEL / CER | Chip Enable (Left/Right) | Active-low enables respective port; controls entry into standby (ISB1/ISB2) or full standby (ISB3/ISB4) |
| OEL / OER | Output Enable (Left/Right) | Active-low enables I/O drivers; high-Z state prevents bus contention during multi-port sharing |
| R/WL / R/WR | Read/Write Control (Left/Right) | High = read, low = write; determines direction of data flow on associated I/O bus |
| BUSYL / BUSYR | Arbitration Flag (Left/Right) | Open-drain outputs indicating port contention; require external pull-up resistors to VCC |
| INTL / INTR | Interrupt Flag (Left/Right) | Push-pull outputs used to signal inter-port events (e.g., write completion, address match) |
| A0L–A9L / A0R–A9R | Address Inputs (Left/Right) | 10-bit address buses enabling full 1K-word access per port; asynchronous and independent |
| I/O0L–I/O7L / I/O0R–I/O7R | Data I/O (Left/Right) | Bidirectional 8-bit data paths; tri-stated when OE high or CE high |
Key Features
| Feature | Design Value |
|---|---|
| On-chip arbitration logic | Eliminates need for external glue logic in MASTER/SLAVE configurations; resolves simultaneous access via BUSY assertion |
| Dual independent asynchronous ports | Enables concurrent CPU/DSP or host/peripheral access without software coordination or shared bus arbitration overhead |
| TTL-compatible I/O | Direct interfacing with legacy 5V microcontrollers, FPGAs, and ASICs without level shifters or voltage translators |
| Multiple standby power modes | Supports dynamic power management: ISB1 (both ports disabled), ISB2 (one active), ISB3/ISB4 (CMOS-level input hold) |
| Port-to-port interrupt signaling | Hardware-triggered INTL/INTR flags reduce latency vs. polling and simplify real-time inter-processor synchronization |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C131-20VXI | 5V, 1K × 8, 20 ns, but lacks on-chip arbitration logic and BUSY/INT flags | Requires external logic for MASTER/SLAVE expansion and inter-port signaling | Select when cost-sensitive designs can implement arbitration externally and do not require hardware interrupts |
| IDT7140SA20PF | Same FP48 package and speed grade, but SLAVE-only: BUSY inputs (not outputs), no arbitration logic | Cannot operate standalone; must pair with 7130 as MASTER; no INT flag generation capability | Select only as companion device to expand data width beyond 8 bits in systems already using 7130SA20PF |
Compared with CY7C131-20VXI, 7130SA20PF integrates arbitration and interrupt functions, reducing BOM count and PCB area; compared with IDT7140SA20PF, it provides autonomous MASTER functionality essential for stand-alone dual-port use cases.

FAQ
What is the maximum operating temperature range for the 7130SA20PF?
The 7130SA20PF is rated for industrial temperature operation from –40°C to +85°C. This specification is explicitly confirmed in the "Recommended Operating Temperature and Supply Voltage" table (2689 tbl 03) and applies to all SA-speed variants in FP48 packaging. It does not support military-grade (–55°C to +125°C) or commercial-grade (0°C to +70°C) ranges - those apply to other suffix variants.
Does the 7130SA20PF support battery backup data retention?
No, the 7130SA20PF does not support battery backup data retention. That capability is exclusive to LA-suffix variants (e.g., 7130LA20PF), which specify 2.0 V minimum retention voltage and microamp-level retention current. The SA suffix denotes standard active power performance without low-voltage retention circuitry - confirmed in DC Electrical Characteristics (2689 tbl 04) and Data Retention Characteristics tables (2689 tbl 07), which list LA-only parameters.
How does BUSY arbitration work on the 7130SA20PF?
On the 7130SA20PF, BUSYL and BUSYR are open-drain outputs that assert low when contention is detected on the opposite port. Arbitration prioritizes the port whose address and control signals stabilize first, governed by tAPS (5 ns min). If timing priority cannot be resolved, either BUSY line may assert - but both will never be low simultaneously. External pull-up resistors are required, as stated in Functional Block Diagram Note 1 and Pin Configurations notes.
Can the 7130SA20PF be used as a standalone 8-bit memory without a SLAVE device?
Yes, the 7130SA20PF functions fully as a standalone 8-bit dual-port SRAM. Its MASTER designation indicates capability to coordinate with IDT7140 SLAVE devices for wider data buses, but it operates independently with complete left/right port control, arbitration, and interrupt features. The datasheet states: "IDT7130 is designed to be used as a stand-alone 8-bit Dual-Port RAM or as a 'MASTER'... together with the IDT7140 'SLAVE'."
What package type is used for the 7130SA20PF?
The 7130SA20PF uses a 48-pin ceramic flatpack (FP48) package, with dimensions approximately 0.75 in × 0.75 in × 0.11 in. This is explicitly identified in the Pin Configurations section (2689 drw 03F) and confirmed in ordering information notes referencing "FP48(4)" and "48-Pin Flatpack Top View." It is distinct from DIP, LCC, PLCC, or TQFP variants.
