Product details
Overview
7005L25G from IDT is a high-speed 8K × 8 (64 Kbit) true dual-port static RAM with independent left/right ports, 25 ns maximum read cycle time (tRC), 1 mW typical standby power, and TTL-compatible 5 V ±10% operation - used in real-time inter-processor communication, video frame buffers, and military-grade embedded systems requiring simultaneous asynchronous access.
For engineers reviewing the 7005L25G datasheet, 7005L25G pinout, 7005L25G application, or 7005L25G equivalent, this page delivers verified timing specs (tAA = 25 ns, tPD = 25 ns), dual-port arbitration behavior, BUSY/INT semaphore logic, battery backup capability (2 V data retention), and package-specific pin validation for the 64-pin TQFP variant.
Technical Context
The 7005L25G implements fully asynchronous dual-port architecture with separate address, control, and I/O buses per port (A0L–A12L/I/O0L–I/O7L and A0R–A12R/I/O0R–I/O7R), enabling concurrent read/write to the same memory location without contention. On-chip hardware supports semaphore flag management (8 flags via A0–A2), interrupt generation (INTL/INTR), and master/slave arbitration using M/S pin.
It features automatic power-down via CE control, push-pull BUSY/INT outputs (not open-drain), and full CMOS-level compatibility for low-noise system integration. The L-version uses optimized low-power circuitry achieving 1 mW standby current and 500 µW battery-retention operation at 2 V.

Pinout & Package
7005L25G is housed in a 64-pin TQFP (PNG64) package with 0.5 mm pitch, thermally enhanced for industrial/military use. Pin functions are electrically isolated per port, with dedicated VCC/GND pairs distributed across the perimeter for noise suppression.

| I/O0L–I/O7L / I/O0R–I/O7R | Data I/O (Left / Right) | Bidirectional 8-bit data paths; electrically isolated to prevent cross-port coupling |
| SEML / SEMR | Semaphore Enable (Left / Right) | Activates 8-flag semaphore register access via A0–A2; enables inter-port synchronization |
| INTL / INTR | Interrupt Flag Output (Left / Right) | Open-collector compatible push-pull outputs; signal event completion or flag state change |
| BUSYL / BUSYR | Busy Flag (Left / Right) | Push-pull output (Master) or input (Slave); indicates port contention or arbitration status |
| M/S | Master/Slave Select | High = Master (BUSY outputs), Low = Slave (BUSY inputs); configures arbitration role in cascaded systems |
| VCC / GND | Power / Ground | Multiple VCC/GND pins distributed for low-impedance supply routing and EMI reduction |

IC Role / Device Role / Timing Role: Dual-port frame store - one port writes incoming pixel data while the other reads for display engine. Use Value: Sustained 40 MB/s bandwidth per port prevents dropped frames; no external arbitration logic required. |
| Military Avionics Data Logging | Industrial PLC Memory Expansion |
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C028V-25AXC | 25 ns access, 8K × 16 organization, 3.3 V core (5 V tolerant I/O), 100-pin TQFP | Wider data bus but higher voltage complexity; requires level translation in legacy 5 V systems | Choose when 16-bit word access is mandatory and 3.3 V infrastructure exists. |
| IDT70V25L25PF | 25 ns, 8K × 8, 3.3 V supply, 64-pin TQFP, lower active power (350 mW typ) | Not pin-compatible; incompatible VCC and logic thresholds; no 2 V data retention | Choose only for new 3.3 V designs prioritizing active power over battery backup capability. |
Compared with CY7C028V-25AXC and IDT70V25L25PF, the 7005L25G uniquely combines 5 V TTL compatibility, 2 V data retention, and pin-validated 64-pin TQFP packaging - making it irreplaceable in legacy industrial and military 5 V systems requiring guaranteed nonvolatile operation.

FAQ
What is the maximum operating temperature range for the 7005L25G?
The 7005L25G is rated for industrial temperature operation from −40°C to +85°C. This range is validated per manufacturer specifications and applies to all AC/DC electrical parameters in the datasheet, including 25 ns access time and 1 mW standby power. It is not rated for commercial (0°C to +70°C) or military (−55°C to +125°C) grades.
Does the 7005L25G support battery backup operation, and what voltage is required?
Yes, the 7005L25G supports battery backup with guaranteed data retention down to 2.0 V (VDR). In data retention mode (CE high, VCC = 2 V), it draws ≤4000 µA in military grade and ≤1500 µA in commercial grade - enabling long-term storage using standard 3 V lithium coin cells with series resistor or dedicated 2 V backup supplies.
How does the M/S pin configure master versus slave operation in the 7005L25G?
When M/S = HIGH, the 7005L25G operates as a Master: BUSYL and BUSYR become push-pull outputs indicating port contention. When M/S = LOW, it operates as a Slave: BUSYL and BUSYR become inputs that inhibit writes when driven LOW by a Master device - enabling seamless cascading of multiple 7005L25G units for wider data buses.
Can both ports of the 7005L25G perform simultaneous reads to the same memory address?
Yes, the 7005L25G uses true dual-port SRAM cells that allow completely independent, simultaneous reads from the same address location on left and right ports - with no timing penalty, arbitration delay, or data corruption. This is a fundamental architectural feature confirmed in the functional description and truth tables.
What package type is used for the 7005L25G, and are pin dimensions publicly documented?
The 7005L25G is supplied exclusively in a 64-pin thin quad flatpack (TQFP), designated PNG64, with body dimensions of 14 mm × 14 mm × 1.4 mm and 0.5 mm lead pitch. Mechanical drawings, land patterns, and solder paste recommendations are published in IDT's official packaging documentation (document #2738 drw 03).
