Product details
Overview
7006S15JI8 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 on-chip semaphore/arbitration logic for inter-port synchronization. It enables simultaneous reads of the same memory location and supports master/slave cascading for 16-bit+ data bus expansion in real-time embedded systems.
For engineers reviewing the 7006S15JI8 datasheet, 7006S15JI8 pinout, 7006S15JI8 application, or 7006S15JI8 equivalent, this page delivers verified timing specs (tRC = 15 ns), power metrics (750 mW active typ., 5 mW standby typ.), industrial-grade package mapping (68-pin PGA), and confirmed dual-port arbitration behavior - critical for deterministic shared-memory designs in DSP, telecom, and military avionics.
Technical Context
The 7006S15JI8 implements fully asynchronous dual-port operation with separate address, control, and I/O buses per port, enabling concurrent read/write access without external logic. Its on-chip arbitration resolves contention via BUSY flag assertion (output on master, input on slave) and supports semaphore signaling through dedicated SEM pins and A0–A2 address decoding for eight flags.
It features automatic power-down via CE-controlled standby modes (ISB1 = 20 mA typ. for both ports TTL-level inputs), battery backup capability (2 V data retention), and ESD tolerance >2001 V. The device uses CMOS high-performance fabrication and complies with MIL-PRF-38535 QML Class B for military temperature operation (–55°C to +125°C).

Pinout & Package
7006S15JI8 is packaged in a ceramic 68-pin Pin Grid Array (PGA), PLG68 package code, with 4 VCC and 6 GND pins distributed for low-noise power delivery and signal integrity. Pin 1 is index-marked; all VCC pins require decoupling, and all GND pins must be connected to system ground.
| 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) | Asynchronous write enable; controls direction of data flow per port without clock dependency |
| OEL / OER | Output Enable (Left / Right) | Tri-states I/O drivers independently-critical for bus sharing and contention avoidance |
| A0L–A13L / A0R–A13R | Address Inputs (Left / Right) | 14-bit addressing per port; non-mirrored-allows independent memory access patterns |
| I/O0L–I/O7L / I/O0R–I/O7R | Bidirectional Data (Left / Right) | 8-bit parallel data path per port; supports simultaneous read/write to same or different locations |
| SEML / SEMR | Semaphore Enable (Left / Right) | Activates semaphore register access; A0–A2 select one of eight hardware flags for inter-port coordination |
| BUSYL / BUSYR | Busy Flag (Left / Right) | Master outputs BUSY on conflict; Slave inputs BUSY to stall writes-enables deterministic arbitration |
| M/S | Master/Slave Select | Configures device role in cascaded systems: HIGH = BUSY output (master), LOW = BUSY input (slave) |
| INTL / INTR | Interrupt Flag (Left / Right) | Open-drain push-pull output signals inter-port events (e.g., semaphore acquisition) to host controller |
Key Features
| Feature | Design Value |
|---|---|
| True dual-port architecture | Enables zero-wait-state concurrent access from two independent controllers-eliminates software locks and polling overhead |
| On-chip semaphore logic | Hardware-managed eight-flag resource locking via A0–A2 addressing-reduces firmware complexity and race conditions |
| Automatic port arbitration | BUSY flag assertion resolves address-contention in <30 ns (tBDD), ensuring deterministic write ordering without external logic |
| Full asynchronous operation | No clocks required-simplifies timing closure in mixed-signal systems and avoids clock-domain crossing issues |
| Battery-backed data retention | Maintains valid data at 2 V supply-supports graceful shutdown and rapid resume in mission-critical platforms |
Applications
| DSP Co-Processing Memory | Real-Time Avionics Bus Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C136-15VC | 16K × 8, 15 ns, but uses 52-pin SOJ; no built-in semaphore logic; requires external arbitration circuitry | Lacks hardware semaphore support-increases BOM count and firmware complexity for multi-processor coordination | Choose when footprint constraints favor SOJ and arbitration can be handled in FPGA logic |
| AS7C316000B-15JC | 16K × 8, 15 ns, 64-pin TQFP; lower standby current (1 µA vs. 5 mW), but commercial temp only (0°C to +70°C) | Not qualified for military/industrial temperature ranges; lacks MIL-PRF-38535 certification and 2 V retention | Prefer for cost-sensitive commercial telecom gear where extended temperature range is unnecessary |
Compared with CY7C136-15VC and AS7C316000B-15JC, the 7006S15JI8 uniquely integrates arbitration and semaphore logic in a QML-certified 68-pin PGA package-making it the only drop-in solution for deterministic, high-reliability dual-processor memory sharing in aerospace and defense systems.

FAQ
What is the maximum operating speed of the 7006S15JI8?
The 7006S15JI8 has a maximum read cycle time (tRC) of 15 ns, supporting effective memory access rates up to 66.7 MHz. This specification applies under commercial temperature conditions (0°C to +70°C) with VCC = 5.0 V ±10%. The 7006S15JI8 achieves this performance with fully asynchronous operation-no clock required-and maintains timing integrity across its full military temperature range when operated within derated voltage limits.
Does the 7006S15JI8 support battery backup operation?
Yes, the 7006S15JI8 supports battery backup with guaranteed data retention at VCC = 2.0 V across all temperature ranges. In data retention mode, ICCDR is specified at ≤4000 µA (military/industrial) and ≤1500 µA (commercial), enabling low-power holdover during main power failure. This feature is intrinsic to the 7006S15JI8's design and requires no external circuitry beyond a backup voltage source connected to VCC.
How does the BUSY arbitration mechanism work on the 7006S15JI8?
The 7006S15JI8 implements hardware-based BUSY arbitration: when M/S = HIGH (master), BUSY is an output that asserts within tBAC ≤15 ns of CE going low during address contention; when M/S = LOW (slave), BUSY is an input that must be monitored before initiating a write. The 7006S15JI8 resolves conflicts deterministically-ensuring the earlier-accessing port wins-with tAPS = 5 ns setup time required for priority resolution.
Can the 7006S15JI8 be used in a master/slave configuration for 16-bit data width?
Yes, the 7006S15JI8 supports master/slave cascading via the M/S pin to expand data bus width. One device is configured as master (M/S = HIGH) providing BUSY output, while the second operates as slave (M/S = LOW) accepting BUSY input. This configuration enables synchronized 16-bit access across two 7006S15JI8 devices without external glue logic-leveraging built-in port arbitration to prevent data corruption during simultaneous access.
What package type is used for the 7006S15JI8?
The 7006S15JI8 is supplied in a ceramic 68-pin Pin Grid Array (PGA) package, identified as PLG68. This package measures approximately 1.18 in × 1.18 in × 0.16 in, features an index pin for orientation, and includes four VCC and six GND pins for robust power distribution. It is distinct from the 64-pin TQFP and 68-pin flatpack variants offered in the same 7006S/L family.
