Product details
Overview
7130SA100PF8 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, 100ns maximum read/write cycle time, open-drain BUSY outputs requiring pull-up resistors, and TTL-compatible 5V ±10% operation - used in real-time inter-processor communication systems where concurrent left/right port access prevents bus contention.
For engineers reviewing the 7130SA100PF8 datasheet, 7130SA100PF8 pinout, 7130SA100PF8 application, or 7130SA100PF8 equivalent, key selection criteria include its master arbitration capability, 100ns timing grade, FP48 ceramic flatpack package, industrial temperature range (–40°C to +85°C), and compatibility with IDT7140SLAVE devices for 16-bit memory expansion.
Technical Context
The 7130SA100PF8 implements fully asynchronous dual-port architecture with independent left/right address, control, and I/O buses. Its on-chip arbitration logic resolves simultaneous access to the same memory location by asserting BUSYL/BUSYR outputs - open-drain signals that require external pull-up resistors per datasheet Note 1 and 2.
It supports port-to-port interrupt signaling via INTL/INTR pins and enables battery-backed data retention only in LA variants (not applicable here); this SA variant operates exclusively in active/standby modes with 550mW typical active power and 5mW typical standby power at 5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 1K × 8 bits (1024 words × 8-bit data width per port) |
| Max Read/Write Cycle Time | 100ns - defines minimum time between successive read or write operations on either port |
| Supply Voltage | 4.5V to 5.5V - requires single 5V ±10% rail; all VCC pins must be connected |
| Operating Temperature | –40°C to +85°C - industrial grade; validated across full range per Table 03 |
| Active Current (ICC) | 110mA typical - measured with both ports active, f = fMAX, outputs disabled |
| Standby Current (ISB1) | 20mA max - both ports disabled (CEL/CER = VIH), TTL-level inputs, f = fMAX |
| BUSY Output Type | Open-drain - requires external pull-up resistor; used for port arbitration and write inhibition |
Pinout & Package
7130SA100PF8 is supplied in a 48-pin ceramic flatpack (FP48) package measuring approximately 0.75 in × 0.75 in × 0.11 in, with gull-wing leads and index mark orientation per drawing 2689 drw 03F.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 24, 25, 48) | Ground reference | All four GND pins must be connected to system ground per Note 2 |
| VCC (Pins 23, 31) | Power supply | Both VCC pins must be connected to 4.5–5.5V supply per Note 1 |
| CEL / CER | Chip Enable (Left/Right) | Active-low enables port access; controls power-down mode when high |
| OEL / OER | Output Enable (Left/Right) | Active-low enables I/O drivers; high-Z when high |
| R/WL / R/WR | Read/Write Control (Left/Right) | High = read, low = write; controls direction of data flow per port |
| BUSYL / BUSYR | Arbitration Flag (Left/Right) | Open-drain outputs indicating port contention; require pull-up resistors |
| INTL / INTR | Interrupt Flag (Left/Right) | Open-drain outputs signaling inter-port events; require pull-up resistors |
| A0L–A9L / A0R–A9R | Address Inputs (Left/Right) | 10-bit address buses selecting one of 1024 memory locations per port |
| I/O0L–I/O7L / I/O0R–I/O7R | Data I/O (Left/Right) | Bidirectional 8-bit data paths; high-impedance when OE or CE inactive |
Key Features
| Feature | Design Value |
|---|---|
| On-chip arbitration logic | Resolves simultaneous left/right port access to same address without external logic |
| Master-only BUSY output | BUSYL/BUSYR are open-drain outputs (not inputs) - distinguishes 7130SA from SLAVE 7140 |
| Port-to-port interrupt signaling | INTL/INTR flags enable hardware-synchronized inter-processor communication |
| Full asynchronous dual-port operation | Independent control/address/I/O per port allows concurrent read/write without clock coordination |
| TTL-compatible interface | Direct connection to 5V TTL logic families without level-shifting circuitry |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C131-100AXC | 1K × 8, 100ns, 5V, but no on-chip arbitration logic; BUSY is not implemented | Requires external logic for contention resolution; unsuitable as direct MASTER replacement | Select only if arbitration handled externally and footprint compatibility confirmed |
| IDT7140SA100PF8 | Same speed/package, but SLAVE-only: BUSY pins are inputs, no arbitration logic, no INT flag generation | Cannot operate stand-alone; must pair with 7130SA as MASTER; no interrupt signaling capability | Use only in MASTER/SLAVE 16-bit expansion configurations, not as functional substitute |
Compared with CY7C131-100AXC and IDT7140SA100PF8, the 7130SA100PF8 uniquely integrates arbitration and interrupt generation - eliminating external glue logic in real-time dual-CPU systems while maintaining pin-compatibility within the IDT7130/7140 family.

FAQ
What is the operating temperature range for the 7130SA100PF8?
The 7130SA100PF8 is rated for industrial temperature operation from –40°C to +85°C, as specified in Table 03 of the datasheet. This range is validated across all DC and AC electrical characteristics, including 100ns timing performance and standby current limits. It does not support commercial (0°C to +70°C) or military (–55°C to +125°C) grades - those require different suffixes (e.g., 7130SC or 7130SM).
Does the 7130SA100PF8 support battery backup data retention?
No, the 7130SA100PF8 does not support battery backup data retention. That feature is exclusive to the LA variant (e.g., 7130LA100PF8), which specifies 2.0V data retention voltage and microamp-level retention current in Table 07. The "SA" suffix denotes standard active power consumption (550mW typical), and the 7130SA100PF8 requires continuous 4.5–5.5V supply to maintain data integrity.
How are the BUSY pins used on the 7130SA100PF8?
On the 7130SA100PF8, BUSYL and BUSYR are open-drain outputs (not inputs) used for port arbitration - asserted low when the opposite port attempts a conflicting write to the same address. Per datasheet Notes 1 and 2, external pull-up resistors are mandatory. These signals internally inhibit writes when driven low, enabling hardware-based contention resolution without software intervention.
Can the 7130SA100PF8 be used as a standalone dual-port RAM without a SLAVE device?
Yes, the 7130SA100PF8 functions fully as a standalone 8-bit dual-port SRAM. Its on-chip arbitration logic, BUSY outputs, and interrupt flags operate independently. The SLAVE (7140) is optional and only required when expanding to 16-bit or wider data buses - the 7130SA100PF8 does not depend on external devices for basic dual-port operation, read/write, or arbitration.
What package type is used for the 7130SA100PF8?
The 7130SA100PF8 uses a 48-pin ceramic flatpack (FP48) package, as indicated by the "PF8" suffix. Per drawing 2689 drw 03F, it measures approximately 0.75 in × 0.75 in × 0.11 in with gull-wing leads. This hermetically sealed ceramic package provides superior thermal stability and moisture resistance compared to plastic DIP or LCC variants, supporting industrial and extended-temperature reliability requirements.
