Product details
Overview
7006L35GB from IDT is a high-speed 16K × 8 dual-port static RAM with true independent left/right port access, 35 ns maximum read cycle time, 2 V battery backup data retention, and industrial temperature range (–40°C to +85°C). It implements on-chip arbitration, semaphore signaling, and BUSY flag logic for real-time inter-processor communication in embedded control systems.
For engineers reviewing the 7006L35GB datasheet, 7006L35GB pinout, 7006L35GB application, or 7006L35GB equivalent, this page delivers verified timing specs, validated pin functions, confirmed package mapping to 64-pin TQFP, and two field-proven alternative parts for memory coherency designs requiring simultaneous dual-access SRAM.
Technical Context
The 7006L35GB uses fully asynchronous CMOS architecture with separate address, control, and I/O buses per port. Its on-chip arbitration logic resolves contention via M/S-selectable master/slave configuration and supports both address-match and chip-enable BUSY assertion modes.
It integrates eight hardware semaphores addressed by A0–A2, with dedicated SEM/INT/BUSY terminals enabling lock-step synchronization between heterogeneous processors. The device operates at 5.0 V ±10% and enters ultra-low-power standby (1 µA typ.) when CE is deasserted.

| SEML / SEMR | Semaphore Enable (Left / Right) | Activates hardware semaphore register bank (8 flags) for inter-processor locking |
| INTL / INTR | Interrupt Flag (Left / Right) | Open-drain outputs signaling semaphore state change or write completion |
| BUSYL / BUSYR | Busy Flag (Left / Right) | Push-pull output (Master) or input (Slave); indicates port contention during concurrent access |

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-35AXC | 35 ns access, 16K × 16 organization, 3.3 V core, 5 V tolerant I/O | Wider data bus reduces interface complexity but requires voltage translation in 5 V systems | Select when 16-bit word alignment simplifies processor bus interface and lower core voltage is acceptable |
| AS7C3256B-35JCIN | 35 ns access, 32K × 8 organization, 3.3 V only, no BUSY/SEM hardware | Larger memory depth but lacks integrated arbitration - requires external logic for multi-processor sync | Select when higher density is needed and software-managed semaphores are viable in the RTOS environment |
Compared with CY7C024AV-35AXC and AS7C3256B-35JCIN, the 7006L35GB uniquely delivers 5 V native operation, hardware BUSY arbitration, and battery-retained 2 V data hold - making it optimal for legacy industrial and avionics platforms where voltage compatibility and deterministic contention resolution are mandatory.

FAQ
What is the guaranteed maximum read cycle time for the 7006L35GB?
The 7006L35GB has a guaranteed maximum read cycle time (tRC) of 35 ns across its specified industrial temperature range (–40°C to +85°C) and supply voltage (5.0 V ±10%). This value is production-tested and applies to both ports under worst-case operating conditions, enabling reliable 28.6 MHz dual-port operation without external wait-state insertion.
Does the 7006L35GB support battery backup operation, and what is the minimum retention voltage?
Yes, the 7006L35GB supports battery backup operation with a minimum data retention voltage of 2.0 V. In retention mode (VCC ≤ 2.0 V, CE high), the device maintains stored data while drawing less than 4 mA typical current - verified per IDT specification table 2739 tbl 09. This capability is exclusive to the "L" (low-power) variant, such as the 7006L35GB.
How does the M/S pin configure arbitration behavior in a multi-device 7006L35GB system?
When M/S = VIH, the 7006L35GB operates as a Master: BUSYL and BUSYR are push-pull outputs that assert during port contention. When M/S = VIL, it operates as a Slave: BUSYL and BUSYR become inputs, allowing external BUSY signals from a Master device to gate local write operations - enabling hierarchical arbitration in cascaded configurations without additional logic.
What are the key differences between the 7006L35GB and the 7006S35GB variants?
The 7006L35GB and 7006S35GB share identical speed grade (35 ns), pinout, and functionality, but differ in power profile: the "L" variant consumes 700 mW typical active power and 1 µA typical standby current, while the "S" variant consumes 750 mW active and 5 µA standby. The 7006L35GB is optimized for battery-backed or thermally constrained applications where ultra-low standby current is critical.
Which package type is used by the 7006L35GB, and are thermal pads exposed?
The 7006L35GB uses a 64-pin thin quad flatpack (TQFP) package, designated PNG64, with dimensions 14 mm × 14 mm × 1.4 mm. Per IDT documentation (2739 drw 03), this package has no exposed thermal pad - all thermal dissipation occurs through leads and package body. PCB layout must follow standard TQFP thermal relief guidelines for 5 V, 128 Kbit SRAM power density.
