Product details
Overview
70V06L15PFG8 from IDT (now Renesas) is a high-speed 3.3V 16K × 8 true dual-port static RAM with independent left/right ports, 15 ns max read cycle time (commercial grade), TTL-compatible I/O, and integrated port arbitration logic. It enables simultaneous asynchronous access to the same memory location and supports master/slave cascading for 16-bit+ data bus expansion in real-time inter-processor communication systems.
For engineers reviewing the 70V06L15PFG8 datasheet, 70V06L15PFG8 pinout, 70V06L15PFG8 application, or 70V06L15PFG8 equivalent, key selection considerations include BUSY/INT semaphore timing compliance, 3.3V ±0.3V supply operation, industrial temperature support (−40°C to +85°C), and PLCC-68 package mechanical compatibility with legacy board layouts.
Technical Context
The 70V06L15PFG8 implements fully asynchronous dual-port architecture with separate address, control, and bidirectional I/O buses per port. Its on-chip arbitration logic resolves contention via BUSY flag assertion (push-pull output) when both ports access identical addresses, with tBDD ≤ 18 ns (M/S = VIH) ensuring deterministic data validity after conflict resolution.
It integrates dedicated semaphore registers (8 flags, addressed by A0–A2), interrupt mailbox logic (INTL/INTR set/clear at 3FFEh/3FFFh), and automatic power-down per port via CE-driven standby modes-supporting ISB3 ≤ 0.2 mA full standby current with CMOS-level inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 16K × 8 bits (128 Kbit), two independent addressable spaces |
| Access Time (tAA) | 15 ns max - guarantees sub-67 MHz read throughput per port |
| Supply Voltage | 3.3 V ± 0.3 V - compatible with standard LVTTL and LVCMOS interfaces |
| Operating Temperature | −40°C to +85°C - qualified for industrial embedded control applications |
| Standby Current (ISB3) | 0.2 mA max - enables ultra-low-power hold mode during idle port cycles |
| Bus Interface | True dual-port: separate A0L–A13L/I/O0L–I/O7L and A0R–A13R/I/O0R–I/O7R - no external logic needed for concurrent access |
| Arbitration Logic | Hardware BUSY flag with tAPS = 5 ns setup - ensures deterministic priority resolution without software overhead |

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, TQFP-100 package | Wider data bus eliminates need for cascading but requires PCB redesign and higher pin count | Select when 16-bit native interface is required and layout revision is feasible |
| IS61LV25616AL-10TLI | 256K × 16, 10 ns access, 3.3 V, TSOP-44; single-port only with external arbitration | Lacks integrated BUSY/semaphore logic - requires FPGA or CPLD for coherency management | Select only if higher density is critical and additional logic resources are available |
Compared with CY7C024AV-15AXC and IS61LV25616AL-10TLI, the 70V06L15PFG8 uniquely delivers true dual-port operation with hardware arbitration in a legacy-compatible PLCC-68 package-enabling drop-in replacement in existing industrial designs without layout change or firmware modification.

FAQ
What is the maximum operating frequency supported by the 70V06L15PFG8?
The 70V06L15PFG8 supports a maximum read cycle time (tRC) of 15 ns, enabling reliable operation up to 66.7 MHz per port under commercial temperature conditions. Its fully asynchronous design means no clock signal is required-timing is governed solely by address and control signal propagation delays, making it suitable for mixed-signal systems with asynchronous domain crossing.
Does the 70V06L15PFG8 support battery backup operation?
Yes, the 70V06L15PFG8 supports battery backup operation with guaranteed data retention down to 2.0 V on VDD. This allows the device to maintain stored values during main power loss or brown-out events, provided backup voltage remains within absolute maximum ratings (−0.5 V to +4.6 V) and leakage current stays within specification limits.
How does the BUSY arbitration logic function in the 70V06L15PFG8?
In the 70V06L15PFG8, BUSY arbitration asserts BUSYL or BUSYR when both ports attempt to access the same memory address. When configured as Master (M/S = VIH), BUSY is an output that blocks writes on the contending port until the conflict resolves. The tBDD parameter (≤18 ns) defines the delay from BUSY deassertion to valid data availability, ensuring deterministic recovery.
Can the 70V06L15PFG8 be used in a 16-bit data path configuration?
Yes-the 70V06L15PFG8 supports 16-bit expansion using its Master/Slave select (M/S) feature. Two devices can be cascaded: one as Master (BUSY output) and one as Slave (BUSY input), with shared address/data buses and independent CE/R/W controls. This eliminates external logic and maintains full 15 ns speed across the combined 16-bit word.
What are the key differences between the 70V06L15PFG8 and the 70V06S15PFG8?
The 70V06L15PFG8 and 70V06S15PFG8 share identical pinout, timing, and functionality but differ in power consumption: the 'L' suffix denotes low-power variant (ISB3 ≤ 0.2 mA), while 'S' indicates standard power (ISB3 ≤ 1.0 mA). Both operate at 15 ns speed and support −40°C to +85°C industrial temperature range, making the 'L' version preferred for thermally constrained or battery-operated systems.
