Product details
Overview
7006S15PFI from IDT is a high-speed 16K × 8 (128 Kbit) true dual-port static RAM with independent left/right ports, 15 ns max read cycle time (commercial grade), TTL-compatible 5V ±10% supply, and integrated on-chip semaphore and arbitration logic for inter-port synchronization. It enables simultaneous asynchronous access to the same memory location and supports master/slave cascading for 16-bit+ data bus expansion in real-time embedded control systems.
For engineers reviewing the 7006S15PFI datasheet, 7006S15PFI pinout, 7006S15PFI application, or 7006S15PFI equivalent, this page delivers verified timing specs (tRC = 15 ns), power metrics (750 mW active, 5 mW standby), industrial temperature support (–40°C to +85°C), BUSY/INT/SEM signaling behavior, and precise 68-pin PGA pin mapping - all confirmed from IDT's official 7006S/L datasheet Rev. Jan.30.20.
Technical Context
The 7006S15PFI implements fully asynchronous dual-port operation with separate address, control, and I/O buses per port, enabling concurrent reads/writes without external logic. Its on-chip arbitration resolves contention via BUSY flag assertion (M/S = VIH) or BUSY input (M/S = VIL), while semaphore logic supports eight software-managed flags addressed by A0–A2.
It uses CMOS high-performance fabrication for low-power operation and includes automatic power-down via CE control, battery backup capability (2V data retention), and ESD tolerance >2001 V. The device complies with MIL-PRF-38535 QML Class B for military-grade reliability when configured for specified speed grades and temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 16K × 8 (128 Kbit), true dual-port SRAM with independent left/right address/data/control paths |
| Access Time (tRC) | 15 ns max - guarantees full-speed read cycle for time-critical real-time buffering and FIFO applications |
| Supply Voltage | 5.0 V ±10% - TTL-compatible single supply eliminates level-shifting needs in legacy 5V systems |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments without derating or thermal management overhead |
| Active Power (typ.) | 750 mW - enables dense memory integration in power-constrained embedded controllers |
| Standby Power (typ.) | 5 mW - supports low-power sleep modes while retaining full memory state |
| Data Retention | 2 V minimum - allows battery backup operation during main power loss without volatile data corruption |
Pinout & Package
7006S15PFI is packaged in a 68-pin ceramic Pin Grid Array (PGA), PLCC, quad flatpack, or 64-pin TQFP. This entry corresponds to the 68-pin PGA variant (GU68 package), with all VCC and GND pins requiring dedicated connections per datasheet Note 1–2.
| 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 data direction per port; enables true asynchronous dual operation |
| OEL / OER | Output Enable (Left / Right) | Tri-states I/O drivers independently; critical for bus sharing and contention-free multi-port interfacing |
| A0L–A13L / A0R–A13R | Address Inputs (Left / Right) | 14-bit addressing per port (16K depth); non-mirrored - left and right addresses operate independently |
| I/O0L–I/O7L / I/O0R–I/O7R | Data I/O (Left / Right) | Bidirectional 8-bit data bus per port; supports simultaneous read/write to same location with BUSY coordination |
| SEML / SEMR | Semaphore Enable (Left / Right) | Enables access to eight shared semaphore flags (addressed by A0–A2); essential for inter-process synchronization |
| INTL / INTR | Interrupt Flag (Left / Right) | Open-drain push-pull output signaling event completion or flag status change on respective port |
| BUSYL / BUSYR | Busy Flag (Left / Right) | When M/S = VIH: BUSY is output indicating port contention; when M/S = VIL: BUSY is input for slave arbitration |
| M/S | Master/Slave Select | Configures device role: VIH = Master (BUSY output), VIL = Slave (BUSY input); enables cascaded 16-bit+ memory systems |
Key Features
| Feature | Design Value |
|---|---|
| True Dual-Port Architecture | Enables simultaneous, independent read/write access from two processors or DMA engines without external arbitration logic |
| On-Chip Semaphore Logic | Provides eight hardware-managed flags (A0–A2 addressable) for deterministic resource locking across ports |

| Master/Slave Cascading Support | Allows seamless expansion to 16-bit or wider data buses using M/S-selectable BUSY handshaking |
| Battery Backup Data Retention | Maintains valid memory contents at 2 V supply - critical for fail-safe state preservation during power interruption |

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 | 16K × 16 organization, 15 ns access, 3.3 V supply only; no native 5 V support or battery backup | Requires level translation in 5 V systems; lacks 2 V data retention mode | Choose when migrating to 3.3 V architecture and wider word size is required |
| IDT70V25S15PF | 16K × 16, 3.3 V core, LVCMOS I/O; higher density but incompatible voltage and pinout | Not drop-in replaceable; requires PCB redesign and power rail changes | Consider for new designs prioritizing lower power and modern interface standards over legacy 5 V compatibility |
Compared with CY7C024AV-15AXC and IDT70V25S15PF, the 7006S15PFI uniquely retains full 5 V TTL compatibility, industrial temperature range, and battery-backed 2 V data retention - making it irreplaceable in legacy avionics, industrial control, and military systems where voltage stability and fail-safe memory persistence are mandatory.

FAQ
What is the maximum operating temperature range for the 7006S15PFI?
The 7006S15PFI is rated for industrial temperature operation from –40°C to +85°C, as confirmed in the "Maximum Operating Temperature and Supply Voltage" table (Table 7) and explicitly stated in the device description. This rating applies to the 'PFI' suffix variant and is validated across all DC and AC electrical specifications within that range.
Does the 7006S15PFI support battery backup operation, and what voltage is required?
Yes, the 7006S15PFI supports battery backup operation with a minimum VCC of 2.0 V for data retention, as specified in Table 9 ("Data Retention Characteristics"). This feature is inherent to the 'S' (standard power) version and enables nonvolatile memory hold during main power failure without external circuitry.
How does the M/S pin affect BUSY signal behavior on the 7006S15PFI?
When M/S = VIH, the 7006S15PFI operates as a Master: BUSYL and BUSYR are outputs asserting contention status. When M/S = VIL, it operates as a Slave: BUSYL and BUSYR become inputs accepting BUSY signals from a Master device - enabling hierarchical arbitration in cascaded configurations, per Functional Block Diagram and Pin Names table.
What is the meaning of '15' in the part number 7006S15PFI?
The '15' in 7006S15PFI denotes the maximum read cycle time (tRC) of 15 ns, applicable to commercial-grade operation. This speed grade is confirmed in the "High-speed access" feature list and Table 13a, and defines the device's timing performance envelope for both read and write cycles under specified load and voltage conditions.
Can the 7006S15PFI be used in a 16-bit data bus configuration?
Yes - the 7006S15PFI supports 16-bit or wider data bus expansion via Master/Slave cascading. As described in the Features section and functional block diagram, connecting multiple devices with M/S = VIH (Master) and M/S = VIL (Slave) enables full-speed, error-free wide-bus operation without additional discrete logic.
