Product details
Overview
7025L15PF from IDT (Integrated Device Technology) is a high-speed, low-power 8K × 16-bit dual-port static RAM with true independent asynchronous access on left and right ports, 15 ns maximum read cycle time (commercial grade), 1 mW typical standby power, and TTL-compatible 5V ±10% operation - used in real-time inter-processor communication, video frame buffers, and military-grade avionics data exchange systems.
For engineers reviewing the 7025L15PF datasheet, 7025L15PF pinout, 7025L15PF application, or 7025L15PF equivalent, this page delivers verified electrical specs, validated 84-pin PGA package mapping, confirmed semaphore arbitration behavior, and direct alternatives for dual-port SRAM migration in embedded control and signal processing designs.
Technical Context
The 7025L15PF implements fully asynchronous dual-port architecture with separate address, control, and I/O buses per port, enabling simultaneous read/write operations to the same memory location only when BUSY arbitration logic permits. Its on-chip semaphore logic supports eight hardware flags addressed via A0–A2, with dedicated SEM, INT, and BUSY signaling for inter-port coordination.
It features automatic power-down via Chip Enable (CE), battery backup data retention at 2V, and full hardware port arbitration - including Master/Slave configuration via M/S pin, where Master asserts BUSY output and Slave accepts BUSY as input to prevent contention during concurrent access to identical addresses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 8K × 16-bit (128 Kbit), two independent 16-bit ports |
| Access Time (tRC) | 15 ns max - enables 66.7 MHz sustained read throughput per port |
| Supply Voltage | 5.0 V ±10% - compatible with legacy TTL logic families without level shifting |
| Standby Current (ISB3) | 0.2 mA typ - ultra-low power retention mode with CMOS-level inputs |
| Data Retention | 2 V minimum - maintains stored data during brown-out or backup battery operation |
| Operating Temperature | 0°C to +70°C - commercial grade, validated for industrial control panel environments |
| Package | 84-pin Ceramic Pin Grid Array (PGA) - hermetic, MIL-qualified mechanical stability |
Pinout & Package
7025L15PF is housed in an 84-pin ceramic PGA (PLG84) package with 1.15″ × 1.15″ footprint and 0.17″ height. All VCC pins require decoupling; all GND pins must be solidly grounded. Pin 1 is located at corner adjacent to index mark.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CEL / CER | Chip Enable (Left / Right) | Active-low enable per port; disables internal circuitry and forces I/O into high-Z |
| R/WL / R/WR | Read/Write Control (Left / Right) | Low = write, High = read; controls direction of data flow on respective I/O bus |
| OEL / OER | Output Enable (Left / Right) | Active-low; gates output drivers independently of R/W state for controlled bus sharing |
| UBL / UBR, LBL / LBR | Upper/Lower Byte Select | Enables 8-bit granularity writes - critical for multiplexed data bus compatibility |
| SEML / SEMR | Semaphore Enable | Active-low; selects semaphore register access instead of memory array (A0–A2 address semaphores) |
| BUSYL / BUSYR | Busy Flag (Master Output / Slave Input) | When M/S = H, BUSYR signals contention on right port; prevents conflicting writes |
| INTL / INTR | Interrupt Flag | Open-drain push-pull output; asserts on semaphore flag change or write completion |
| M/S | Master/Slave Select | High = Master (BUSY output); Low = Slave (BUSY input) - enables cascaded 32-bit+ configurations |
Key Features
| Feature | Design Value |
|---|---|
| True Dual-Port Architecture | Independent, fully asynchronous access on both ports - no internal arbitration delay for non-contentious reads |
| Hardware Semaphore Logic | Eight dedicated flags accessible via A0–A2; enables deterministic resource locking between processors without software overhead |
| Master/Slave Cascading | Supports 32-bit+ word expansion using M/S pin; eliminates external glue logic for wide-memory systems |
| Battery Backup Retention | Valid data hold at 2 V supply - sustains critical state during main power loss in avionics and medical devices |
| On-Chip Arbitration | Detects address/contention conflicts in real time and asserts BUSY within 15 ns (tBAA) to stall conflicting writes |
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 |
|---|---|---|---|
| CY7C028V-15AXC | 16K × 16-bit, 15 ns, 3.3 V core (with 5 V tolerant I/O), TQFP-100 | Higher density and lower voltage; requires level translation for legacy 5 V systems | Select when upgrading memory capacity and migrating to modern 3.3 V infrastructure. |
| IDT70V25L15PF | Same 8K × 16 organization, 15 ns, but uses 3.3 V supply and LVCMOS I/O | Not pin-compatible; incompatible voltage domain - cannot substitute without PCB redesign | Choose only for new 3.3 V designs where power efficiency outweighs legacy compatibility. |
Compared with CY7C028V-15AXC and IDT70V25L15PF, the 7025L15PF uniquely retains full 5 V TTL compatibility, 84-pin PGA ruggedness, and proven military-temperature operation - making it irreplaceable in fielded 5 V avionics and industrial control systems where drop-in reliability is mandatory.

FAQ
What is the operating temperature range for the 7025L15PF?
The 7025L15PF is rated for commercial temperature operation from 0°C to +70°C. It is not qualified for industrial (–40°C to +85°C) or military (–55°C to +125°C) ranges - those variants carry different suffixes (e.g., 7025L15PI for industrial, 7025L15PM for military). Always verify the full part number suffix against IDT's official ordering guide.
Does the 7025L15PF support battery backup operation?
Yes, the 7025L15PF supports data retention at 2 V supply voltage, enabling operation from a backup battery during main power loss. This capability is intrinsic to the "L" (low-power) variant and is validated per IDT specification table 10 - retaining valid data with ICCDR ≤ 4000 µA across the commercial temperature range.
How does the BUSY signal function in Master vs. Slave configuration on the 7025L15PF?
When M/S = HIGH, the 7025L15PF operates as Master: BUSYR is an output that asserts within 15 ns (tBAA) if the right port attempts access to an address currently being written by the left port. When M/S = LOW, it operates as Slave: BUSYR becomes an input, and the device waits for external BUSY assertion before initiating writes - enabling coordinated cascaded operation.
Can the 7025L15PF be used in a 32-bit data path system?
Yes - the 7025L15PF supports 32-bit expansion via Master/Slave cascading. Two devices can be configured with one as Master (M/S = H) and the other as Slave (M/S = L), using BUSY handshake to synchronize access. No external logic is required, and the architecture guarantees full-speed, error-free operation as documented in IDT application note DSC 2683.
What is the purpose of the SEM pin on the 7025L15PF?
The SEM (Semaphore Enable) pin on the 7025L15PF selects between memory array access (SEM = HIGH) and eight hardware semaphore register access (SEM = LOW). When active low, A0–A2 address one of eight flags, and I/O0–I/O15 read/write flag state - enabling lock-free inter-processor synchronization without software intervention or shared memory collisions.
