Product details
Overview
IDT7006L20JI8 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 (tRC), TTL-compatible 5V ±10% operation, and industrial temperature range (–40°C to +85°C). It supports simultaneous reads of the same memory location and provides on-chip semaphore signaling for inter-port coordination in real-time embedded systems.
For engineers reviewing the IDT7006L20JI8 datasheet, IDT7006L20JI8 pinout, IDT7006L20JI8 application, or IDT7006L20JI8 equivalent, key selection considerations include its 20 ns access timing, low-power standby current (1 µA typ.), BUSY/INT flag support, master/slave arbitration capability, and compatibility with 64-pin TQFP packaging for space-constrained designs.
Technical Context
The IDT7006L20JI8 implements fully asynchronous dual-port architecture with separate address, control, and I/O buses per port-enabling concurrent read/write operations without external logic. Its on-chip arbitration logic resolves contention via BUSY flag assertion and supports semaphore-based resource locking using A0–A2 address lines to select among eight flags.
It features two distinct power modes: active operation at 700 mW typical (L-version), and ultra-low standby at 1 µW typical under CE-high conditions. Battery backup data retention is supported down to 2 V, enabling nonvolatile operation during main supply interruption.
Key Specifications

| Package | 64-pin TQFP (PNG64), 14 mm × 14 mm × 1.4 mm - surface-mount compatible with automated PCB assembly |
| Bus Arbitration | Hardware-supported BUSY/INT flags and semaphore logic - eliminates need for external arbitration logic in multi-processor systems |
Pinout & Package
Package: 64-pin Thin Quad Flatpack (TQFP), body size 14 mm × 14 mm × 1.4 mm, lead pitch 0.5 mm, RoHS-compliant and green-part qualified.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| A0L–A13L | Left Port Address Inputs | 14-bit address bus for left-side memory access; decodes 16K locations independently of right port |
| A0R–A13R | Right Port Address Inputs | 14-bit address bus for right-side memory access; fully asynchronous with left port |
| I/O0L–I/O7L | Left Port Data I/O | Bi-directional 8-bit data path; tri-stated when OEL high or CEL high |
| I/O0R–I/O7R | Right Port Data I/O | Bi-directional 8-bit data path; tri-stated when OER high or CER high |
| CEL / CER | Chip Enable (Left/Right) | Active-low enables respective port; controls power-down mode when high |
| OEL / OER | Output Enable (Left/Right) | Active-low enables output drivers; used with R/WL/R/WR to control read direction |
| R/WL / R/WR | Read/Write Control (Left/Right) | Active-low write enable; high = read (outputs enabled if OE low), low = write (inputs sampled) |
| SEML / SEMR | Semaphore Enable (Left/Right) | Active-low selects semaphore register access instead of RAM array; enables inter-port signaling |
| BUSYL / BUSYR | Busy Flag (Left/Right) | Open-drain output (BUSYL) or input (BUSYR) in slave mode; signals port contention during shared-address writes |
| INTL / INTR | Interrupt Flag (Left/Right) | Open-drain outputs indicating semaphore or memory event; requires external pull-up |
| M/S | Master/Slave Select | High = master (BUSY output); low = slave (BUSY input); configures arbitration behavior in cascaded systems |
| VCC / GND | Power Supply | Four VCC and six GND pins distributed for low-noise, low-impedance power delivery across high-speed operation |
Key Features
| Feature | Design Value |
|---|---|
| True Dual-Port Architecture | Enables simultaneous, independent read/write access from both ports - no internal arbitration delay for non-contentious operations |
| On-Chip Semaphore Logic | Eight hardware semaphore flags accessible via A0–A2 and SEML/SEMR - eliminates software polling or external lock registers |
| Automatic Power-Down | CE-driven transition to 1 µA standby current - reduces system power without requiring external sleep controllers |
| 2V Data Retention | Maintains stored data during main supply loss using optional 2V backup battery - supports graceful shutdown and fast resume |

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 52-pin PLCC; no integrated semaphore logic; higher standby current (5 µA typ.) | Lacks hardware semaphore and BUSY arbitration - requires external logic or firmware for multi-processor coordination | Choose when footprint compatibility with legacy PLCC layouts is required and arbitration is handled externally. |
| AS7C316000B-20TIN | 20 ns access, 16K × 8, 64-pin TQFP package; CMOS-only interface (not TTL-compatible); 3.3V supply only | Requires level translation for 5V systems; no BUSY/INT flags or M/S configuration - limited to simple dual-buffer use cases | Choose only in new 3.3V designs where TTL compatibility and hardware arbitration are unnecessary. |
Compared with CY7C136-20JC and AS7C316000B-20TIN, the IDT7006L20JI8 uniquely delivers 5V TTL compatibility, integrated semaphore/BUSY logic, and 1 µA standby in a 64-pin TQFP - making it the sole option for industrial 5V systems requiring hardware-coordinated dual-processor memory sharing.

FAQ
What is the maximum operating speed of the IDT7006L20JI8?
The IDT7006L20JI8 has a guaranteed maximum read cycle time (tRC) of 20 ns across the full industrial temperature range (–40°C to +85°C), supporting reliable operation at up to 50 MHz clock rates. This timing applies to both ports independently and is validated under worst-case voltage (4.5 V) and temperature conditions.
Does the IDT7006L20JI8 support battery backup operation?
Yes, the IDT7006L20JI8 supports battery backup data retention at 2 V (VDR = 2.0 V min), maintaining stored contents with typical current draw of 100 µA. This feature is exclusive to the "L" (low-power) version and is specified for all temperature grades, enabling fail-safe memory preservation during main power loss.
How does the BUSY arbitration mechanism work on the IDT7006L20JI8?
The IDT7006L20JI8 uses hardware BUSY flag assertion to manage port contention: when both ports attempt to write to the same address simultaneously, the master port (M/S = H) asserts BUSY on the slave port, blocking its write until the master completes. The tBDD parameter (30 ns max) defines the delay from BUSY deassertion to valid read data.
Can the IDT7006L20JI8 be used in a 3.3V system?
No - the IDT7006L20JI8 is strictly a 5V device, specified for operation at 4.5 V to 5.5 V. Its inputs are TTL-compatible (VIH = 2.2 V min), and outputs swing rail-to-rail within 5V margins. Interfacing with 3.3V logic requires level translation; it is not 3.3V tolerant and may be damaged if VCC falls below 4.5V or exceeds 5.5V.
What is the function of the M/S pin on the IDT7006L20JI8?
The M/S (Master/Slave Select) pin configures arbitration behavior: when high, the device operates as master with BUSYL as an output flag; when low, it operates as slave with BUSYL as an input. This enables cascaded configurations where one IDT7006L20JI8 coordinates multiple devices without external logic.
