Product details
Overview
7006S17PFI8 from IDT is a high-speed 16K × 8 true dual-port static RAM with independent left/right ports, 17 ns maximum access time (commercial grade), TTL-compatible 5 V ±10% supply, and on-chip semaphore/arbitration logic for concurrent multi-processor memory sharing in real-time control systems.
For engineers reviewing the 7006S17PFI8 datasheet, 7006S17PFI8 pinout, 7006S17PFI8 application, or 7006S17PFI8 equivalent, this page delivers verified timing specs, master/slave BUSY flag behavior, semiconductor-level DC/AC electrical characteristics, and industrial-grade packaging details for deterministic system integration.
Technical Context
The 7006S17PFI8 implements fully asynchronous dual-port architecture with separate address, data, and control buses per port-enabling simultaneous read/write to the same location without external logic. Its on-chip arbitration resolves contention via BUSY flag assertion (M/S = H) or BUSY input (M/S = L), supporting master/slave cascading for 16-bit+ word expansion.
It integrates full hardware semaphore signaling (8 flags, addressed by A0–A2), interrupt flag generation (INTL/INTR), and automatic power-down via CE-controlled standby modes. Battery backup operation retains data at 2 V, with guaranteed 100 µA retention current across military/industrial temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 16K × 8 bits (128 Kbit total, two independent 16K × 8 ports) |
| Access Time (tAA) | 17 ns max - guarantees deterministic read latency for real-time processor coexistence |
| Supply Voltage | 5.0 V ±10% - compatible with legacy TTL bus systems without level-shifting |
| Operating Temperature | –40°C to +85°C - qualified for industrial embedded environments |
| Active Power (typ) | 750 mW - enables thermal management in dense multi-IC control modules |
| Standby Current (ISB1) | 20 mA max (both ports disabled) - supports low-power sleep states in battery-backed systems |
| Data Retention Voltage | 2.0 V minimum - sustains memory state during brown-out or backup battery operation |
Pinout & Package
7006S17PFI8 is packaged in a 64-pin TQFP (PNG64), 14 mm × 14 mm × 1.4 mm body, with 48 I/O/control pins (including dual-port address/data/control), 4 VCC, and 4 GND pins requiring dedicated decoupling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0L–A13L | Left Port Address Inputs | 14-bit address bus for left-side memory access; independent of right port |
| A0R–A13R | Right Port Address Inputs | 14-bit address bus for right-side access; no shared address lines |
| I/O0L–I/O7L | Left Port Bidirectional Data | 8-bit data path; tri-stated when OEL = H or CEL = H |
| I/O0R–I/O7R | Right Port Bidirectional Data | 8-bit data path; tri-stated when OER = H or CER = H |
| CEL / CER | Chip Enable (Left/Right) | Active-low enables port-specific memory access and power gating |
| OEL / OER | Output Enable (Left/Right) | Active-low controls output drivers; overrides R/WL/R/WR for read enable |
| R/WL / R/WR | Read/Write Control (Left/Right) | Active-low write enable; high = read (when CE and OE active) |
| SEML / SEMR | Semaphore Enable (Left/Right) | Active-low selects semaphore register access instead of RAM array |
| INTL / INTR | Interrupt Flag Output (Left/Right) | Open-drain outputs indicating semaphore/interrupt events; require pull-up |
| BUSYL / BUSYR | Busy Flag (Left/Right) | Push-pull outputs (M/S = H) or inputs (M/S = L); resolve port contention |
| M/S | Master/Slave Select | H = BUSY output (master); L = BUSY input (slave); enables daisy-chained arbitration |
Key Features
| Feature | Design Value |
|---|---|
| True Dual-Port Architecture | Enables simultaneous reads/writes to identical addresses without external arbitration logic |
| On-Chip Semaphore Logic | Eight hardware semaphore flags (A0–A2 addressed) eliminate software overhead in multi-CPU synchronization |
| Master/Slave Cascading | Supports 16-bit+ data bus expansion using M/S pin and BUSY chaining without glue logic |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C136-20JC | 20 ns access time; 5 V only; no built-in semaphore logic; PLCC-68 package | Lacks hardware semaphore support-requires external logic for multi-CPU sync | Select when cost sensitivity outweighs arbitration complexity and 17 ns speed is non-critical |
| IDT70V27L15PF | 3.3 V supply; 15 ns access; LVDS-compatible; 128K × 16 organization | Requires voltage translation for 5 V systems; larger density but incompatible pinout | Choose for new 3.3 V designs needing higher bandwidth and lower power, not drop-in replacement |
Compared with CY7C136-20JC and IDT70V27L15PF, the 7006S17PFI8 uniquely delivers 17 ns speed at 5 V with integrated semaphore/BUSY arbitration-reducing BOM count and layout area in legacy industrial avionics where 5 V tolerance and deterministic contention resolution are mandatory.

FAQ
What is the maximum operating temperature range for the 7006S17PFI8?
The 7006S17PFI8 is rated for industrial temperature operation from –40°C to +85°C. This specification is validated per the datasheet's "Maximum Operating Temperature and Supply Voltage" table and applies to all speed grades within the 7006S/L family, including the 17 ns variant. The device maintains full 17 ns access time performance across this full range.
Does the 7006S17PFI8 support battery backup operation, and what voltage is required?
Yes, the 7006S17PFI8 supports battery backup operation with guaranteed data retention at 2.0 V minimum (VDR). Per the "Data Retention Characteristics" table, it draws ≤100 µA typical retention current at 2 V, enabling sustained memory state during main power loss-a key requirement for fail-safe industrial and medical systems.
How does the M/S pin configure master versus slave operation in the 7006S17PFI8?
When M/S = H, the 7006S17PFI8 operates as a master: BUSYL and BUSYR become push-pull outputs asserting busy status during port contention. When M/S = L, it operates as a slave: BUSYL and BUSYR become inputs, allowing external BUSY signals from a master device to gate writes-enabling daisy-chained arbitration in multi-device configurations.
What are the key differences between the 7006S and 7006L variants, and which applies to 7006S17PFI8?
The 7006S17PFI8 is an "S" (Standard) variant: active power is 750 mW typical, standby is 5 mW typical. The "L" (Low-power) variant consumes 700 mW active and 1 mW standby, with enhanced 2 V data retention capability. The "S" designation in the part number confirms it is the standard-power version optimized for speed-critical industrial applications.
Can the 7006S17PFI8 be used in a 16-bit data bus configuration, and how is that implemented?
Yes-the 7006S17PFI8 supports 16-bit expansion via master/slave cascading. Two devices are connected with M/S = H (master) and M/S = L (slave); BUSY outputs from the master drive BUSY inputs on the slave. The IDT7006 MASTER/SLAVE approach eliminates external logic, delivering full-speed error-free 16-bit operation as confirmed in the device description section.
