Product details
Overview
7006S35PF 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 (tRC), TTL-compatible 5 V ±10% supply, and integrated on-chip semaphore and BUSY arbitration logic. It enables simultaneous reads of 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 7006S35PF datasheet, 7006S35PF pinout, 7006S35PF application, or 7006S35PF equivalent, this device is selected for deterministic port arbitration, battery-backed data retention down to 2 V, and industrial temperature operation (–40°C to +85°C) in embedded control, avionics data buffers, and dual-CPU shared-memory architectures.
Technical Context
The 7006S35PF 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 resolves contention via BUSY flag assertion (M/S = H) or BUSY input (M/S = L), with priority set-up time tAPS = 5 ns and port-to-port write-to-read delay tDDD ≤ 35 ns.
It integrates full hardware semaphore signaling across eight flags addressed by A0–A2, supporting inter-processor synchronization without software overhead. The device operates in three power modes: active (typ. 150 mA), standby (ISB1 = 13 mA), and full standby (ISB3 = 1.0 mA), with data retention at 2 V and < 4 µA ICCDR.
Key Specifications

| Supply Voltage | 4.5 V to 5.5 V - compatible with standard TTL logic rails and industrial 5 V systems |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded control and avionics environments |
| Power Consumption | Active: 150 mA typ; Standby (ISB1): 13 mA typ - enables low-power idle states in battery-backed systems |
| Data Retention | 2 V minimum VCC - retains valid data during brown-out or backup-battery operation |
| Package | 64-pin TQFP (PNG64), 14 mm × 14 mm × 1.4 mm - surface-mount compatible with high-density PCB layouts |
Pinout & Package
7006S35PF is housed in a 64-pin thin quad flatpack (TQFP), package code PNG64, with 48 signal pins (including dual-port I/O, address, control), 8 power/ground pins (4×VCC, 4×GND), and 8 no-connect (N/C) pins. Pin layout supports symmetric routing for left/right port symmetry and EMI-reduced power distribution.
| Pin/Terminal | 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 access; no aliasing with left port addresses |
| 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) | Asynchronous enable per port; controls active/standby current state independently |
| R/WL / R/WR | Read/write control (left/right) | Active-low write enable; determines direction of I/O buffer for each port |
| OEL / OER | Output enable (left/right) | Tri-states outputs independently; allows one port to drive while other reads |
| SEML / SEMR | Semaphore enable (left/right) | Enables access to 8 semaphore flags via I/O0–I/O7 using A0–A2 |
| BUSYL / BUSYR | Busy flag (left/right) | When M/S = H: BUSY is output (master); when M/S = L: BUSY is input (slave) |
| INTL / INTR | Interrupt flag (left/right) | Open-drain push-pull output; signals semaphore or memory event to host processor |
| M/S | Master/slave select | Configures arbitration role: H = master (BUSY output), L = slave (BUSY input) |
| VCC / GND | Power and ground | Four VCC and four GND pins ensure low-noise, low-impedance supply distribution |
Key Features
| Feature | Design Value |
|---|---|
| True dual-port memory cells | Enables simultaneous read of identical address by both ports - eliminates arbitration latency for status mirroring |
| On-chip semaphore logic | Eight hardware semaphore flags accessible via A0–A2 and I/O0–I/O7 - removes need for external lock registers |
| Automatic power-down control | CE-driven transition to 1.0 mA full-standby mode - reduces system power during idle without software intervention |
| Port-to-port arbitration with BUSY | Hardware-resolved contention via tAPS = 5 ns setup and tBDD ≤ 35 ns disable-to-valid-data - ensures deterministic inter-processor sync |
| Battery backup capability | Valid data retention at 2 V VCC with ICCDR ≤ 4 µA - supports seamless switchover to backup power |
| TTL-compatible interface | VIH = 2.2 V min, VIL = 0.8 V max - interoperable with legacy 5 V microcontrollers and FPGAs without level shifters |
Applications
| Avionics Data Buffer | Dual-CPU Shared Memory |
|---|---|

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 | 32K × 16 organization, 35 ns tRC, 3.3 V core (with 5 V tolerant I/O), 100-pin TQFP | Higher density and lower voltage; requires level translation for pure 5 V systems | Select when 32K × 16 width and 3.3 V integration are required; not drop-in for 7006S35PF's 16K × 8 and 5 V native interface. |
| AS7C3256A-35JCIN | 32K × 8 organization, 35 ns tRC, 3.3 V supply only, 54-pin SOJ | No 5 V compatibility; lacks BUSY arbitration and semaphore logic; requires external arbitration logic | Choose for cost-sensitive 3.3 V designs where hardware arbitration is implemented externally; not suitable for 7006S35PF's deterministic contention resolution use cases. |
Compared with CY7C024AV-35AXC and AS7C3256A-35JCIN, the 7006S35PF uniquely delivers 5 V native operation, integrated BUSY/semaphore arbitration, and 16K × 8 organization in a compact 64-pin TQFP - making it optimal for legacy 5 V dual-processor systems requiring minimal external logic.

FAQ
What is the maximum operating temperature range for the 7006S35PF?
The 7006S35PF is rated for industrial temperature operation from –40°C to +85°C. This specification is confirmed in the Absolute Maximum Ratings table and DC Electrical Characteristics section of the official IDT datasheet (document 2739, revision Jan.30.20). It does not support military-grade –55°C to +125°C operation - that range applies only to specific military-specified variants like 7006S35PM.
Does the 7006S35PF support battery backup operation?
Yes, the 7006S35PF supports battery backup operation with guaranteed data retention at VCC = 2.0 V, as specified in Table 9 (Data Retention Characteristics). Typical data retention current (ICCDR) is 100 µA, with a maximum of 4000 µA across military and industrial grades. This feature is intrinsic to the "L" variant designation in the 7006S/L family, and the 7006S35PF implements the low-power retention mode.
How does the M/S pin configure arbitration behavior in the 7006S35PF?
The M/S pin configures the 7006S35PF as either master (M/S = H) or slave (M/S = L). In master mode, BUSY is an output flag indicating port contention; in slave mode, BUSY is an input that blocks writes until deasserted. This is explicitly defined in the Pin Names table (Note 1) and Truth Table II, and enables hierarchical multi-device systems without external glue logic.
What package type is used for the 7006S35PF?
The 7006S35PF uses a 64-pin thin quad flatpack (TQFP), identified as package code PNG64 in the IDT datasheet. Its mechanical dimensions are 14 mm × 14 mm × 1.4 mm, with 0.5 mm lead pitch. This differs from the 68-pin PGA (PLG68), flatpack (FP68), or PLCC variants offered in the broader 7006S/L family - the "PF" suffix in 7006S35PF denotes the TQFP package.
Can the 7006S35PF perform simultaneous reads from both ports to the same memory address?
Yes, the 7006S35PF features true dual-ported memory cells that allow simultaneous reads of the same memory location from both left and right ports without contention or arbitration delay. This capability is explicitly stated in the Features section ("True Dual-Ported memory cells which allow simultaneous reads of the same memory location") and is fundamental to its architecture - no BUSY assertion or timing penalty occurs during concurrent same-address reads.
