Product details
Overview
7005S17PF from IDT is a high-speed 8K × 8 dual-port static RAM with true independent left/right port access, 17 ns maximum read cycle time (tRC), TTL-compatible 5 V ±10% supply, and integrated hardware semaphore/arbitration logic for inter-processor communication in real-time embedded systems.
For engineers reviewing the 7005S17PF datasheet, 7005S17PF pinout, 7005S17PF application, or 7005S17PF equivalent, this device supports simultaneous asynchronous reads/writes across ports, on-chip BUSY flag arbitration, interrupt signaling, and battery-backed data retention down to 2 V - critical for fault-tolerant industrial controllers and military avionics memory subsystems.
Technical Context
The 7005S17PF 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 access without external logic. Its on-chip arbitration uses push-pull BUSY outputs (BUSYL/BUSYR) and M/S select to configure master/slave cascading for 16-bit+ bus expansion.
Hardware semaphore support operates via dedicated SEM pins and A0–A2 address decoding for eight shared flags; interrupt generation is triggered by writes to specific addresses (e.g., 1FFFH sets INTR). All timing parameters-including tAA (17 ns), tACE (17 ns), and tAOE (10 ns)-are specified over commercial temperature range (0°C to +70°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 8K × 8 bits (64 Kbit total), two independent addressable banks |
| Max Read Cycle Time (tRC) | 17 ns - defines minimum clock period for sustained random read throughput |
| Supply Voltage | 5.0 V ±10% - compatible with legacy TTL logic families without level shifting |
| Operating Temperature | 0°C to +70°C - commercial grade, validated for industrial control panels and test equipment |

| Package Type | 64-pin thin quad flatpack (TQFP) - surface-mount compatible with automated assembly |
Pinout & Package
7005S17PF is housed in a 64-pin TQFP (PNG64) package measuring 14 mm × 14 mm × 1.4 mm, with 0.5 mm lead pitch and exposed thermal pad. Pin functions are electrically isolated between left and right ports, supporting full port independence.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CEL / CER | Chip Enable (Left/Right) | Independent port activation; deassertion places respective port in low-power standby |
| R/WL / R/WR | Read/Write Control (Left/Right) | Active-low signal determining direction of data transfer on associated I/O bus |
| OEL / OER | Output Enable (Left/Right) | Gates output drivers; allows tri-state control of I/O pins during shared-bus operation |
| A0L–A12L / A0R–A12R | Address Inputs (Left/Right) | 13-bit address space per port (0–8191); non-mirrored - left and right may access overlapping or disjoint regions |
| I/O0L–I/O7L / I/O0R–I/O7R | Data I/O (Left/Right) | Bidirectional 8-bit data paths; no internal bus contention due to physical separation |
| SEML / SEMR | Semaphore Enable (Left/Right) | Activates semaphore register access mode when CE is high and SEM is low |
| INTL / INTR | Interrupt Flag (Left/Right) | Open-drain compatible output indicating pending inter-port event; requires external pull-up |
| BUSYL / BUSYR | Busy Flag (Left/Right) | Push-pull output (master) or input (slave); signals arbitration conflict during simultaneous address access |
| M/S | Master/Slave Select | High = BUSY outputs enabled (master); Low = BUSY inputs accepted (slave) for daisy-chained configurations |
Key Features
| Feature | Design Value |
|---|---|
| True dual-port memory cells | Enables simultaneous read/write operations on same or different addresses without internal stall cycles |
| On-chip arbitration logic | Eliminates need for external glue logic to resolve port contention; uses BUSY flag handshake with tAPS setup guarantee |
| Hardware semaphore support | Eight dedicated flags accessible via A0–A2 and SEM control - simplifies mutual exclusion in multi-CPU firmware |
| Full asynchronous operation | No clock required; timing governed solely by CE/R/W/OE setup/hold relationships - ideal for mixed-signal SoC interfaces |
| 2 V data retention mode | Preserves memory contents during brown-out or battery switchover without external SRAM controller intervention |

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 tRC, 3.3 V core, LVCMOS I/O - lower power but incompatible voltage domain | Requires level-shifting for 5 V systems; lacks native 2 V data retention | Select only if migrating to 3.3 V infrastructure and redesigning power delivery. |
| IS61WV102416BLL-10TLI | 10 ns tRC, 1M × 16 organization, 3.3 V supply - higher density but wider bus | Not pin-compatible; requires PCB redesign and firmware adaptation for 16-bit interface | Choose for new designs needing >64 Kbit capacity and faster access, not drop-in replacement. |
Compared with CY7C024AV-15AXC and IS61WV102416BLL-10TLI, the 7005S17PF uniquely delivers 5 V TTL compatibility, 2 V battery retention, and proven master/slave cascading - making it irreplaceable in legacy 5 V military and industrial control systems where voltage translation or layout changes are prohibited.

FAQ
What is the maximum operating speed of the 7005S17PF?
The 7005S17PF has a maximum read cycle time (tRC) of 17 ns, corresponding to a theoretical maximum random access rate of 58.8 MHz per port. This speed is guaranteed over the commercial temperature range (0°C to +70°C) with 5.0 V ±10% supply and specified load conditions per the AC test setup in the official datasheet.
Does the 7005S17PF support battery backup operation?
Yes, the 7005S17PF supports battery backup operation with guaranteed data retention at VCC = 2.0 V. In this mode, current draw drops to ≤4000 µA (military/industrial) or ≤1500 µA (commercial), allowing extended hold-up time using small coin-cell batteries - a feature confirmed in the "Data Retention Characteristics" section of the IDT7005 datasheet.
How does the BUSY arbitration logic work on the 7005S17PF?
The 7005S17PF uses push-pull BUSY outputs (BUSYL/BUSYR) when configured as master (M/S = H) to signal port contention. If both ports attempt access to the same address simultaneously, the port meeting tAPS (5 ns arbitration priority setup) first wins; the losing port's BUSY line goes active, inhibiting its write until BUSY deasserts - ensuring deterministic resolution without external logic.
Can the 7005S17PF be used in a master/slave configuration?
Yes, the 7005S17PF supports master/slave cascading via the M/S pin. When M/S = H, BUSYL/BUSYR function as outputs for arbitration signaling; when M/S = L, they become inputs accepting BUSY from a master device. This enables seamless expansion to 16-bit or wider data buses without additional discrete logic - a capability explicitly documented in the IDT7005 functional description.
What package type is used for the 7005S17PF?
The 7005S17PF is supplied in a 64-pin thin quad flatpack (TQFP) package, designated PNG64, with dimensions of 14 mm × 14 mm × 1.4 mm and 0.5 mm lead pitch. This RoHS-compliant surface-mount package is optimized for automated reflow assembly and thermal performance in high-density PCB layouts.
