Details
The IDT7130/IDT7140 are high-speed 1K x 8 Dual-Port Static RAMs. The IDT7130 is designed to be used as a stand-alone 8-bit Dual-Port RAM or as a "MASTER" Dual-Port RAM together with the IDT7140 "SLAVE" Dual-Port in 16-bit-or-more word width systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 16-or more-bit memory system applications results in full-speed, error free operation without the need for additional discrete logic.Features ◆ High-speed access – Commercial: 20/25/35/55/100ns (max.) – Industrial: 25/55/100ns (max.) – Military: 25/35/55/100ns (max.) ◆ Low-power operation – IDT7130/IDT7140SA — Active: 550mW (typ.) — Standby: 5mW (typ.) – IDT7130/IDT7140LA — Active: 550mW (typ.) — Standby: 1mW (typ.) ◆ MASTER IDT7130 easily expands data bus width to 16-or more-bits using SLAVE IDT7140 ◆ Fully asynchronous operation from either port ◆ Battery backup operation–2V data retention (LA only) ◆ TTL-compatible, single 5V ±10% power supply ◆ Military product compliant to MIL-PRF-38535 QML ◆ Industrial temperature range (–40°C to +85°C) is available for selected speeds ◆ Available in 48-pin DIP, LCC and Ceramic Flatpack, 52-pin PLCC, and 64-pin STQFP and TQFP ◆ Green parts available, see ordering information

FAQs
What is IDT7130?
The IDT7130 is a high-speed 1K x 8 Dual-Port Static RAM (SPRAM) designed by Integrated Device Technology (IDT). It is suitable for applications requiring fast access times, high bandwidth, and simple interfacing, such as networking equipment, telecommunications, and industrial control systems.
How Does IDT7130 Work?
The IDT7130 works by providing dual-ported access to its memory array, allowing independent read and write operations from two different sources. It features a fully asynchronous operation, enabling concurrent access to the memory from different clock domains. This makes it suitable for multi-processor systems and peripheral interfacing applications.
How Many Pins does IDT7130 have and What are the Functions of the Pinout Configuration?
The IDT7130 is typically housed in a 48-pin TSOP (Thin Small Outline Package) or similar package. The pinout configuration includes:
- A0-A9: Address input pins.
- Q0-Q7: Data input/output pins for Port A.
- BHE: Byte High Enable, controls the upper byte of the data bus for Port A.
- BLE: Byte Low Enable, controls the lower byte of the data bus for Port A.
- CEA1, CEA2: Chip Enable inputs for Port A.
- WEA1, WEA2: Write Enable inputs for Port A.
- CLKA1, CLKA2: Clock inputs for Port A.
- IRQ: Interrupt output pin.
- VCC, GND: Power supply and ground pins.
- Other address, data, and control pins for Port B are similarly present.
What are the Pros and Cons of IDT7130?
Pros:
- High Speed: Offers fast access times and high bandwidth for demanding applications.
- Dual-Ported Design: Allows simultaneous access for independent read and write operations.
- Asynchronous Operation: Enables concurrent access from different clock domains, supporting multi-processor applications.
- Simple Interface: Provides straightforward interfacing with minimal control signals.
- Reliability: Features static RAM technology for reliable and predictable behavior.
Cons:
- Complex Timing Requirements: Requires careful consideration of timing parameters for correct operation in multi-processor systems.
- Power Consumption: May consume higher power compared to asynchronous SRAM devices in certain operating conditions.
- Package Size: The larger package size may not be suitable for space-constrained designs.
Are There Any Equivalents/Alternatives to IDT7130 for Recommendation?
- The CY7C1460AV25 from Cypress Semiconductor offers similar dual-port SRAM functionality.
- Alternatives to the IDT7130 include the AS6C1008-55SIN from Alliance Memory and the MCM6290BP25 from Motorola.
