Product details
Overview
7005S17PFI from IDT is a high-speed 8K × 8 dual-port static RAM with true independent left/right ports, 17 ns maximum access time (commercial grade), TTL-compatible 5V ±10% supply, and on-chip semaphore/arbitration logic for real-time inter-processor communication in embedded control systems.
For engineers reviewing the 7005S17PFI datasheet, 7005S17PFI pinout, 7005S17PFI application, or 7005S17PFI equivalent, key selection criteria include simultaneous read capability, BUSY/INT flag timing, Master/Slave cascading support, and industrial-grade thermal stability up to +85°C.
Technical Context
The 7005S17PFI implements fully asynchronous dual-port architecture with separate address, data, and control buses per port (A0L–A12L/I/O0L–I/O7L/R/WL/CEL/OEL/BUSYL/INTL/SEML on left; symmetric right-side signals). It uses CMOS high-performance fabrication for low active power (750 mW typ.) and supports battery backup (2 V data retention).
On-chip arbitration includes hardware semaphore signaling (8 flags addressed via A0–A2), automatic BUSY flag generation during address contention, and interrupt flag set/reset via dedicated addresses (1FFFH/1FFE H), all operating without external logic when cascading MASTER/SLAVE configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 8K × 8 bits (64 Kbit), organized as two independent 8K-word × 8-bit ports |
| Access Time | 17 ns max (commercial temperature range, 0°C to +70°C) |
| Supply Voltage | 5.0 V ±10% - single rail, TTL-compatible interface levels |
| Power Consumption | 750 mW typical active; 5 mW typical standby (IDT7005S variant) |
| Data Retention | 2 V minimum VCC for data hold - enables battery backup operation |
| Operating Temp | Industrial range available; this PFI suffix denotes -40°C to +85°C qualification |
| Package | 64-pin thin quad flatpack (TQFP), 14 mm × 14 mm × 1.4 mm body |
Pinout & Package
7005S17PFI is housed in a 64-pin TQFP (PNG64) package with 0.5 mm pitch, requiring standard SMT reflow. All VCC pins must be decoupled locally; all GND pins tied to common ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0L–A12L | Left port address inputs | 13-bit address bus for left-side memory access (0000H–1FFFH) |
| I/O0L–I/O7L | Left port bidirectional data | 8-bit parallel I/O path; tri-stated when OEL = H or CEL = H |
| CEL, OEL, R/WL | Left port controls | Chip Enable, Output Enable, Read/Write Enable - fully asynchronous operation |
| BUSYL, INTL, SEML | Left port status/semaphore | BUSY output (Master) or input (Slave); interrupt flag; semaphore enable |
| A0R–A12R | Right port address inputs | Independent 13-bit address bus - no requirement for mirroring left-side addresses |
| I/O0R–I/O7R | Right port bidirectional data | Electrically isolated 8-bit path; concurrent reads/writes possible across ports |
| CER, OER, R/WR | Right port controls | Asymmetric enable logic allows independent power-down of either port |
| BUSYR, INTR, SEMR | Right port status/semaphore | Matched functionality to left side; supports cross-port synchronization |
| M/S | Master/Slave select | H = BUSY outputs asserted; L = BUSY inputs accepted - enables daisy-chained arbitration |
| VCC, GND | Power & ground | Multiple VCC/GND pins distributed for low-noise operation and EMI reduction |
Key Features
| Feature | Design Value |
|---|---|
| True dual-port memory cells | Enables simultaneous read from same location on both ports - eliminates arbitration delay for shared status registers |
| Hardware semaphore logic | Eight dedicated flags accessed via A0–A2; write to I/O0 sets, read from I/O0–I/O7 retrieves - no software overhead |
| Automatic port arbitration | BUSY flag asserts automatically on address match or CE overlap - prevents destructive write collisions without CPU intervention |
| Master/Slave cascading | M/S pin configures device as master (BUSY output) or slave (BUSY input) - enables 16-bit+ data bus expansion without glue logic |
| 2V data retention mode | Operates down to 2 V VCC while preserving contents - supports nonvolatile backup using coin-cell batteries |
Applications
| Real-Time Industrial PLC | Dual-Core Embedded Controller |
|---|---|
Use Scenario: Two independent microcontrollers share sensor data and actuator commands in a safety-critical motion control system. IC Role / Device Role / Timing Role: 7005S17PFI serves as synchronized shared memory with hardware-enforced mutual exclusion via semaphore flags.

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-15AXC | 15 ns access, 8K × 16 organization, 3.3 V core with 5 V tolerant I/O | Requires external byte-enable logic for 8-bit interfacing; lacks native M/S cascading | Select when 3.3 V system integration or wider data paths are prioritized over seamless 8-bit dual-port expansion |
| IS61LV25616AL-10TLI | 10 ns access, 256K × 16, single-port with internal burst mode | No hardware semaphore or BUSY arbitration; requires external logic for dual-processor sync | Choose for higher density and speed in non-contention scenarios where software-managed coherency suffices |
Compared with CY7C024AV-15AXC and IS61LV25616AL-10TLI, the 7005S17PFI uniquely delivers true dual-port concurrency, integrated arbitration, and Master/Slave scalability in a 5 V, 8-bit-native form factor - critical for deterministic real-time inter-processor communication.

FAQ
What is the maximum operating temperature range certified for the 7005S17PFI?
7005S17PFI is qualified for the industrial temperature range of -40°C to +85°C, as indicated by the 'PFI' suffix in the part number. This exceeds commercial-grade (0°C to +70°C) specifications and supports deployment in harsh environments such as factory automation and transportation systems where ambient thermal stress is significant.
Does the 7005S17PFI support battery backup operation, and what voltage is required?
Yes, the 7005S17PFI supports battery backup operation with data retention down to 2.0 V VCC, as specified in the data retention characteristics table. This enables use with standard 3 V lithium coin cells through a simple diode-OR circuit, maintaining memory contents during main power failure without external refresh circuitry.
How does the Master/Slave (M/S) pin affect BUSY signal behavior on the 7005S17PFI?
When M/S = H, the 7005S17PFI operates as a Master: BUSYL and BUSYR are push-pull outputs that assert automatically during address contention. When M/S = L, it operates as a Slave: BUSYL and BUSYR become inputs that inhibit writes when driven low by a Master - enabling hierarchical arbitration in multi-device systems.
Can both ports of the 7005S17PFI perform simultaneous reads from the same memory location?
Yes, the 7005S17PFI features true dual-port memory cells that allow simultaneous reads from identical addresses on the left and right ports without conflict or performance penalty - a core architectural advantage over pseudo-dual-port or single-port SRAMs with multiplexed access.
What package type is used for the 7005S17PFI, and what are its mechanical dimensions?
7005S17PFI uses a 64-pin thin quad flatpack (TQFP) package designated PNG64, with body dimensions of 14 mm × 14 mm × 1.4 mm. Its 0.5 mm lead pitch and exposed thermal pad support automated assembly and efficient heat dissipation in compact PCB layouts.
