Product details
Overview
IDT7006S20J from Integrated Device Technology (IDT) is a high-speed 16K × 8 dual-port static RAM with true independent left/right port access, 20 ns maximum read cycle time (commercial/industrial), TTL-compatible 5V ±10% operation, and on-chip semaphore arbitration logic-used in real-time inter-processor communication, video frame buffers, and military-grade avionics data exchange systems.
For engineers reviewing the IDT7006S20J datasheet, IDT7006S20J pinout, IDT7006S20J application, or IDT7006S20J equivalent, key selection considerations include simultaneous dual-port read capability, BUSY flag timing (tBAA ≤ 20 ns), M/S-selectable master/slave cascading, battery-backed data retention at 2V, and compatibility with 68-pin PGA, PLCC, or TQFP packages per ordering code.
Technical Context
The IDT7006S20J implements fully asynchronous dual-port architecture with separate address, control, and I/O buses for left (L) and right (R) ports, enabling concurrent read/write operations to the same memory location without contention when BUSY arbitration is enabled. Its on-chip arbitration logic resolves port conflicts via M/S configuration and supports eight hardware semaphores addressed by A0–A2.
It features two independent chip enable (CEL/CER), read/write (R/WL/R/WR), and output enable (OEL/OER) controls per port, plus dedicated semaphore (SEML/SEMR), interrupt (INTL/INTR), and BUSY (BUSYL/BUSYR) signals. All DC/AC parameters-including tRC = 20 ns, ICC = 160 mA (typ), and ISB1 = 20 mA (typ)-are specified over commercial (0°C to +70°C) and industrial (–40°C to +85°C) temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 16K × 8 bits (128 Kbit total); enables byte-wide data transfer per port without external multiplexing. |
| Access Time (tRC) | 20 ns max - guarantees full-speed operation in 50 MHz synchronous bus interfaces with no wait states. |
| Supply Voltage | 5.0 V ±10% - compatible with legacy TTL logic families and eliminates need for level-shifting circuitry. |
| Active Power (ICC) | 160 mA typ (170 mW @ 5V) - supports high-throughput embedded systems while staying within 1 W thermal envelope. |
| Standby Current (ISB1) | 20 mA typ - allows rapid wake-up from low-power mode during burst-mode inter-processor handshaking. |
| Data Retention | 2 V minimum - enables battery backup operation with standard lithium coin cells for nonvolatile state preservation. |
| Operating Temperature | –40°C to +85°C - qualified for industrial control and transportation electronics with extended thermal cycling life. |
Pinout & Package
IDT7006S20J is packaged in a 68-pin Plastic Leaded Chip Carrier (PLCC), with all VCC and GND pins requiring decoupling per layout guidelines. Pin functions are strictly segregated between left (L) and right (R) ports, with no shared signal lines except power and ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0L–A13L | Left port address inputs | 14-bit address bus for 16K-word left-side access; independent of A0R–A13R. |
| I/O0L–I/O7L | Left port bidirectional data | 8-bit parallel data path; tri-stated when OEL = VIH or CEL = VIH. |
| CEL, R/WL, OEL | Left port controls | Chip enable, read/write direction, and output enable-fully asynchronous with no internal clocks. |
| A0R–A13R | Right port address inputs | Independent 14-bit addressing; allows simultaneous access to different memory locations. |
| I/O0R–I/O7R | Right port bidirectional data | Electrically isolated from left I/O; supports concurrent read/write without bus contention. |
| CER, R/WR, OER | Right port controls | Functionally identical to left controls but with separate timing domains and arbitration signaling. |
| SEML, SEMR | Semaphore enable | Activates hardware semaphore flags (8 total) addressed by A0–A2 on respective ports. |
| BUSYL, BUSYR | Arbitration status | BUSYL is output (master) or input (slave); BUSYR mirrors BUSYL behavior for cross-port blocking. |
| M/S | Master/Slave select | M/S = H configures device as master (BUSY output); M/S = L configures as slave (BUSY input). |
| INTL, INTR | Interrupt flags | Open-drain outputs indicating semaphore or memory event; require external pull-up resistors. |
Key Features
| Feature | Design Value |
|---|---|
| True dual-port memory cells | Enables simultaneous reads from both ports to identical addresses-critical for lock-free inter-process data sharing. |
| On-chip semaphore logic | Eight hardware semaphore flags accessed via A0–A2 eliminate need for external arbitration ICs or software mutexes. |
| Automatic power-down | CE-controlled standby mode reduces current to 20 mA (ISB1), enabling dynamic power gating in multi-port systems. |
| Full port-to-port arbitration | BUSY flag generation and priority resolution (tAPS = 5 ns) prevent write collisions during concurrent access. |
| TTL-compatible interface | Direct connection to 5V microcontrollers, FPGAs, and DSPs without level translators or voltage regulators. |

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, 16K × 8, but uses 32-pin SOIC package and lacks M/S master/slave cascade support. | Not suitable for multi-device 16-bit word expansion without external logic; limited to single-port expansion topologies. | Select when board space is constrained and only one dual-port device is needed per subsystem. |
| AS7C316000B-20JC | 20 ns access, 16K × 8, but offers only single CE control and no hardware semaphore or BUSY arbitration logic. | Requires external arbitration circuitry or software coordination for multi-processor use-increasing BOM cost and firmware complexity. | Select for cost-sensitive designs where inter-processor synchronization is handled at software layer. |
Compared with CY7C136-20JC and AS7C316000B-20JC, IDT7006S20J uniquely integrates master/slave cascading, on-chip semaphores, and BUSY-driven arbitration-reducing PCB area, eliminating discrete logic, and guaranteeing deterministic real-time behavior in safety-critical dual-CPU systems.

FAQ
What is the maximum operating temperature range supported by the IDT7006S20J?
The IDT7006S20J is rated for industrial temperature operation from –40°C to +85°C, making it suitable for deployment in harsh environments such as factory automation controllers and outdoor telecommunications equipment. This specification is explicitly confirmed in the "Maximum Operating Temperature and Supply Voltage" table and verified across all AC/DC electrical characteristics sections of the official datasheet.
Does the IDT7006S20J support battery backup for data retention?
Yes, the IDT7006S20J supports battery backup operation with guaranteed data retention at VCC = 2V minimum, as documented in the "Data Retention Characteristics" section. This feature enables nonvolatile state preservation during main power loss, critical for avionics black-box logging and industrial safety shutdown sequences.
How does the M/S pin configure master versus slave operation in the IDT7006S20J?
When M/S = H (high), the IDT7006S20J operates as a master device with BUSYL functioning as an output flag; when M/S = L (low), it operates as a slave with BUSYL configured as an input. This configuration enables daisy-chained multi-device 16-bit-or-wider memory systems without external glue logic, as detailed in the functional block diagram and pin description tables.
What is the purpose of the BUSY flag in the IDT7006S20J, and how is it timed?
The BUSY flag in the IDT7006S20J signals port contention during simultaneous access to the same memory location. With M/S = H, BUSY is asserted within tBAA ≤ 20 ns of address match; with M/S = L, BUSY serves as a write-enable gate. Timing parameters tBAA, tBDA, and tBDD are fully characterized and guaranteed across commercial and industrial grades per Table 15a.
Can the IDT7006S20J be used in systems requiring hardware semaphore support?
Yes, the IDT7006S20J includes full on-chip hardware semaphore logic supporting eight independent flags addressed by A0–A2 on each port. Semaphore read/write operations are controlled via SEM and OE signals, with timing parameters tSOP = 10 ns and tSAA ≤ 20 ns confirmed for the 20 ns speed grade-enabling lock-free resource management in multi-threaded embedded firmware.
