Product details
Overview
7130SA100PF from IDT (Integrated Device Technology) is a high-speed 1K × 8 dual-port static RAM with master arbitration logic, 100ns max read/write cycle time, TTL-compatible 5V ±10% supply, and industrial temperature range (–40°C to +85°C). It enables simultaneous independent access from left and right ports in real-time inter-processor communication systems.
For engineers reviewing the 7130SA100PF datasheet, 7130SA100PF pinout, 7130SA100PF application, or 7130SA100PF equivalent, key selection criteria include BUSY-flag arbitration timing (tBDD ≤ 65ns), dual-port I/O isolation, CE/R/W-controlled write cycles, and compatibility with IDT7140SLAVE expansion for 16-bit+ data buses.
Technical Context
The 7130SA100PF implements on-chip port arbitration logic that asserts BUSYL/BUSYR open-drain outputs when address contention occurs-requiring external pull-up resistors. Its fully asynchronous dual-port architecture supports independent read/write operations on left (A0L–A9L, I/O0L–I/O7L) and right (A0R–A9R, I/O0R–I/O7R) ports without clock synchronization.
It features interrupt signaling via INTL/INTR pins with programmable flag set/reset using dedicated addresses (3FFH for INTR, 3FEH for INTL), and supports battery backup data retention only in LA variants-not applicable to this SA-grade part. Power management includes four standby current modes (ISB1–ISB4) controlled by CE logic levels and input voltage thresholds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1K × 8 bits (1024 words × 8-bit wide), enabling compact buffer storage in space-constrained embedded controllers. |
| Access Time | 100ns maximum (tAA, tACE, tAOE), defining worst-case latency for deterministic real-time response in dual-CPU systems. |
| Supply Voltage | 5.0V ±10% (4.5V–5.5V), compatible with legacy TTL logic families without level-shifting circuitry. |
| Operating Temp | –40°C to +85°C (industrial grade), validated for deployment in factory automation and transportation electronics. |
| Dynamic Current | 110mA typical (ICC, both ports active), supporting low-heat dissipation in densely packed PCB layouts. |
| Standby Current | 20mA max (ISB1, TTL-level CE high), enabling rapid wake-up from low-power states without capacitor recharge delay. |
| Arbitration Delay | tBDD ≤ 65ns (BUSY disable to valid data), ensuring sub-100ns resolution of port contention in synchronized multi-processor memory access. |
Pinout & Package
7130SA100PF is packaged in a 48-pin ceramic flatpack (FP48) with 0.75″ × 0.75″ footprint and 0.11″ height, rated for high-reliability industrial environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 24, 25) | Ground reference | All three GND pins must be connected to system ground plane to ensure stable noise margin and signal integrity across both ports. |
| VCC (Pin 26) | Power supply | Single 5V supply powers internal logic and I/O drivers; decoupling capacitor required within 10mm of pin. |
| CEL / CER | Chip enable (left/right) | Active-low enables respective port; deasserting either disables its I/O drivers and reduces power consumption. |
| OEL / OER | Output enable (left/right) | Active-low controls output buffer state; allows high-Z tri-state during shared bus operation. |
| 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 (open-drain) | Low indicates address conflict on corresponding port; requires external 4.7kΩ pull-up to VCC for proper logic level. |
| INTL / INTR | Interrupt flag (open-drain) | Set/reset via dedicated address writes (3FEH/3FFH); used for inter-processor notification without polling overhead. |
| A0L–A9L / A0R–A9R | Address inputs (left/right) | 10-bit address buses select one of 1024 memory locations independently per port. |
| I/O0L–I/O7L / I/O0R–I/O7R | Data I/O (bidirectional) | 8-bit parallel data path per port; direction controlled by R/W and OE signals-not shared between ports. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip arbitration logic | Eliminates need for external priority encoders or glue logic when implementing dual-CPU shared memory architectures. |
| Independent asynchronous ports | Enables true concurrent access-e.g., CPU1 writing while CPU2 reads same memory array without pipeline stalls. |
| Open-drain BUSY/INT outputs | Supports wired-OR interrupt sharing across multiple devices on common bus lines with single pull-up resistor. |
| Four standby power modes | Allows fine-grained power optimization: ISB3 (CMOS-level CE) draws only 0.2mA typical for ultra-low-power sleep states. |
| TTL-compatible interface | Direct connection to legacy microcontrollers (e.g., 8051, 68K) without level translators or bus buffers. |
Applications
| Real-Time Inter-Processor Communication | Dual-CPU Data Exchange Buffer |
|---|---|
Use Scenario: Two independent microprocessors exchange sensor data and control commands via shared memory without software handshaking. IC Role / Device Role / Timing Role: Acts as master dual-port SRAM with BUSY arbitration to prevent simultaneous writes to same address location. Use Value: Guarantees atomic memory updates with tBDD ≤ 65ns resolution, eliminating race conditions in safety-critical motion control systems. | Use Scenario: Industrial PLC uses left port for main controller and right port for co-processor handling fieldbus protocol stacks. IC Role / Device Role / Timing Role: Provides isolated 1K × 8 memory space accessible by both CPUs at full 100ns speed without clock domain crossing logic. Use Value: Enables zero-latency data transfer between execution domains-critical for deterministic cycle times in servo drive firmware. |
| Legacy System Memory Expansion | Embedded Test Equipment Data Capture |
Use Scenario: Upgrading aging test instrumentation with additional local memory while retaining existing 5V TTL bus architecture. IC Role / Device Role / Timing Role: Replaces discrete latch + SRAM combinations as drop-in-compatible 48-pin FP package with identical pinout to prior-generation parts. Use Value: Reduces BOM count by 3+ components and eliminates timing skew issues from discrete enable propagation delays. | Use Scenario: High-speed logic analyzer captures parallel bus transactions into on-board buffer before streaming to host PC. IC Role / Device Role / Timing Role: Serves as dual-port FIFO where acquisition engine writes via right port and USB interface reads via left port. Use Value: Sustains continuous 10MHz capture rate (tRC = 100ns) with no dead time between samples due to independent port arbitration. |
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-100AXC | 1K × 16 organization, 100ns access, 3.3V supply only; no built-in arbitration logic-requires external BUSY management. | Suitable for wider data paths but incompatible with 5V-only systems; lacks master/slave arbitration needed for seamless CPU coordination. | Select only if migrating to 3.3V design and adding external priority logic is acceptable. |
| IDT7140SA100PF | Same 1K × 8 size and 100ns speed, but SLAVE-only device-no BUSY output or arbitration logic; BUSY pins are inputs only. | Must be paired with IDT7130 as MASTER; cannot operate standalone in arbitration-critical roles like real-time IPC. | Use exclusively as expansion slave when scaling to 16-bit+ word width with IDT7130SA100PF as master controller. |
Compared with CY7C024AV-100AXC, 7130SA100PF delivers native 5V operation and hardware arbitration-reducing system complexity. Against IDT7140SA100PF, it provides autonomous master functionality essential for standalone dual-processor coordination without external logic.

FAQ
What is the maximum operating temperature range for the 7130SA100PF?
The 7130SA100PF is rated for industrial temperature operation from –40°C to +85°C, verified across all electrical parameters including access time (100ns max), standby current (20mA max), and BUSY arbitration timing (tBDD ≤ 65ns). This range ensures reliable performance in factory-floor controllers and outdoor transportation electronics without derating.
Does the 7130SA100PF support battery backup data retention?
No, the 7130SA100PF does not support battery backup data retention. That feature is exclusive to the LA variant (e.g., 7130LA100PF), which specifies VDR = 2.0V minimum and ICCDR ≤ 4000µA at 2V. The SA suffix denotes standard active power profile without low-voltage retention capability.
How is BUSY arbitration implemented on the 7130SA100PF?
The 7130SA100PF implements hardware arbitration using open-drain BUSYL and BUSYR outputs that go low when address contention is detected on the respective port. These signals require external 4.7kΩ pull-up resistors to VCC. Arbitration priority is resolved by tAPS ≥ 5ns setup time; failure to meet this causes undefined BUSY assertion, making precise timing critical in real-time systems.
Can the 7130SA100PF be used as a standalone dual-port RAM without a companion SLAVE device?
Yes, the 7130SA100PF functions fully as a standalone 1K × 8 dual-port SRAM with complete arbitration, interrupt, and control logic integrated. The SLAVE IDT7140 is optional-used only when expanding data bus width beyond 8 bits (e.g., pairing one 7130SA100PF MASTER with two 7140SA100PF SLAVES for 24-bit systems).
What package type is used for the 7130SA100PF?
7130SA100PF uses a 48-pin ceramic flatpack (FP48) package measuring approximately 0.75″ × 0.75″ × 0.11″, with leads brazed to the ceramic body for hermetic sealing and thermal stability. This package is specified in the datasheet drawing "2689 drw 03F" and supports high-reliability industrial and military applications.
