Product details
Overview
7006L15JI8 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), 5 V ±10% single supply, and industrial temperature range (–40°C to +85°C). It supports simultaneous asynchronous access, on-chip semaphore arbitration, and battery-backed data retention down to 2 V.
For engineers reviewing the 7006L15JI8 datasheet, 7006L15JI8 pinout, 7006L15JI8 application, or 7006L15JI8 equivalent, key selection criteria include dual-port contention resolution timing (tBDD ≤ 30 ns), low standby current (1 mW typ), BUSY/INT flag behavior under M/S = VIH, and compatibility with 64-pin TQFP layout for embedded real-time inter-processor communication.
Technical Context
The 7006L15JI8 implements fully asynchronous dual-port operation with separate address, control, and I/O buses per port. Its on-chip arbitration logic resolves simultaneous access via BUSY flag assertion (output when M/S = H, input when M/S = L) and supports semaphore signaling using A0–A2 to select among eight flags.
It features TTL-compatible inputs, push-pull BUSY/INT outputs, and automatic power-down via CE control per port. The device uses CMOS process technology and supports battery backup mode with 2 V data retention-verified for the L-version across all temperature grades.
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 |
| Access Time (tRC) | 15 ns max - enables 66.7 MHz sustained read throughput per port in commercial systems |
| Supply Voltage | 5.0 V ±10% - single-rail TTL-compatible operation; no auxiliary supplies required |
| Standby Current | 1 mW typ (≈200 µA at 5 V) - enables ultra-low-power hold mode during processor idle cycles |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded control and communications equipment |
| Data Retention | 2 V minimum VCC - supports battery backup without external regulators or charge pumps |
| Package | 64-pin TQFP (PNG64), 14 mm × 14 mm × 1.4 mm - surface-mount compatible with automated PCB assembly |
Pinout & Package
7006L15JI8 is housed in a 64-pin thin quad flatpack (TQFP), designated PNG64, with 0.5 mm pitch and exposed thermal pad. All VCC and GND pins must be individually decoupled per datasheet layout guidelines.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| A0L–A13L | Left port address inputs | 14-bit address bus for left-side memory access; independent of right port addressing |
| A0R–A13R | Right port address inputs | 14-bit address bus for right-side memory access; no shared address lines with left port |
| 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 logic; controls power-down entry/exit per port independently |
| OEL / OER | Output enable (left/right) | Active-low enables I/O drivers; overrides R/W state for output gating |
| R/WL / R/WR | Read/write control (left/right) | Active-low write enable; high = read (outputs enabled if OE active) |
| SEML / SEMR | Semaphore enable (left/right) | Active-low selects semaphore register access instead of RAM array |
| BUSYL / BUSYR | Busy flag (left/right) | Push-pull output (M/S = H) or input (M/S = L); signals arbitration conflict on matching addresses |
| INTL / INTR | Interrupt flag (left/right) | Push-pull output; latched on write to interrupt address; cleared by read or reset sequence |
| M/S | Master/slave select | H = master (BUSY output), L = slave (BUSY input); determines arbitration priority in cascaded configurations |
| VCC / GND | Power and ground | Four VCC and six GND pins distributed across package for low-noise, low-impedance supply routing |
Key Features
| Feature | Design Value |
|---|---|
| True dual-port architecture | Enables concurrent read/write from independent processors or DMA engines without external arbitration logic |
| On-chip semaphore logic | Eight hardware semaphore flags accessible via A0–A2; eliminates need for software locks or external semaphores |
| Automatic port arbitration | BUSY flag asserts within 15 ns (tBAA) on address match, blocking conflicting writes until resolution |
| Low-power L-version design | 1 mW typical standby power enables battery-backed operation for >1 year on coin-cell sources |
| 2 V data retention | Preserves memory contents during main power loss without external voltage supervision circuitry |
| TTL-compatible interface | Direct connection to legacy 5 V microcontrollers and FPGAs without level-shifting components |

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 core (5 V tolerant I/O), 100-pin TQFP | Requires wider data bus and different voltage domain; not drop-in compatible | Select when 16-bit word width and lower core voltage are prioritized over pin count and 5 V simplicity |
| IS61LV25616AL-10TLI | 256K × 16, 10 ns access, 3.3 V only, 100-pin TQFP; no dual-port arbitration or BUSY logic | Lacks hardware semaphore, BUSY, or INT flags; requires external logic for coherency | Choose for higher density and speed where software-managed synchronization is acceptable |
Compared with CY7C024AV-15AXC and IS61LV25616AL-10TLI, the 7006L15JI8 uniquely delivers 5 V TTL compatibility, integrated arbitration, and battery-retained operation in a compact 64-pin footprint-making it optimal for cost-sensitive, space-constrained industrial dual-CPU designs.

FAQ
What is the maximum operating frequency supported by the 7006L15JI8?
The 7006L15JI8 does not specify a clock frequency but guarantees a 15 ns maximum read cycle time (tRC), enabling sustained data transfer rates up to 66.7 MHz per port under ideal conditions. Actual system throughput depends on address setup, hold, and output enable timing margins as defined in AC Electrical Characteristics tables.
Does the 7006L15JI8 support true simultaneous read operations from both ports?
Yes, the 7006L15JI8 supports true simultaneous reads from both left and right ports to the same or different memory locations. No BUSY assertion occurs during concurrent reads, and output data is valid within tAA (≤15 ns) after address stabilization on each port independently.
How does the BUSY arbitration mechanism work on the 7006L15JI8?
When M/S = H (master), BUSY is an output that asserts within tBAA (≤15 ns) if both ports access the same address. When M/S = L (slave), BUSY is an input used to stall writes until the master releases the address. This hardware arbitration eliminates race conditions without software intervention.
Can the 7006L15JI8 retain data during main power loss?
Yes, the 7006L15JI8 supports battery backup operation with guaranteed data retention down to 2 V (VDR), verified for the L-version. In retention mode, ICCDR is ≤4000 µA (military/industrial) or ≤1500 µA (commercial), enabling long-term storage on small backup cells.
Is the 7006L15JI8 pin-compatible with other members of the IDT7006 family?
Yes, the 7006L15JI8 shares identical pinout and package (64-pin TQFP) with all IDT7006X15 variants including S- and L-versions across commercial, industrial, and military grades. Only speed grade and power suffix differ; no PCB redesign is needed when substituting within the X15 group.
