Product details
Overview
7006L20PFGI8 from IDT is a high-speed 16K × 8 (128 Kbit) true dual-port static RAM with independent left/right ports, 20 ns maximum access time (industrial grade), 1 mW typical standby power, and TTL-compatible 5 V ±10% operation. It supports simultaneous reads of the same memory location and is used in real-time inter-processor communication systems requiring deterministic arbitration.
For engineers reviewing the 7006L20PFGI8 datasheet, 7006L20PFGI8 pinout, 7006L20PFGI8 application, or 7006L20PFGI8 equivalent, key selection considerations include BUSY/INT semaphore timing (tBAA ≤ 20 ns), dual-port arbitration latency, battery backup data retention at 2 V, and compatibility with 64-pin TQFP layouts for space-constrained embedded controllers.
Technical Context
The 7006L20PFGI8 implements fully asynchronous dual-port architecture with on-chip arbitration logic, enabling conflict-free concurrent access from two independent buses. Its Master/Slave select (M/S) pin configures BUSY as output (Master) or input (Slave), supporting cascaded 16-bit+ word expansion without external logic.
It integrates full hardware semaphore signaling across ports via SEML/SEMR pins and supports both RAM array access (CE = VIL, SEM = VIH) and semaphore flag access (CE = VIH, SEM = VIL), with dedicated interrupt flags (INTL/INTR) and busy arbitration timing validated per MIL-PRF-38535 Class B for industrial temperature operation.

Pinout & Package
7006L20PFGI8 is housed in a 64-pin thin quad flatpack (TQFP, package code PNG64), with 48 I/O and control signals distributed across four sides, plus 8 VCC and 8 GND pins for robust power integrity and noise immunity in high-speed dual-port operation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| A0L–A13L | Left port address inputs | 14-bit address bus for left-side memory access; fully asynchronous with right port |
| A0R–A13R | Right port address inputs | Independent 14-bit address bus; no timing dependency on left port addressing |
| I/O0L–I/O7L | Left port bidirectional data | 8-bit data path; tri-state controlled by OEL/R/WL; supports simultaneous read/write arbitration |
| I/O0R–I/O7R | Right port bidirectional data | 8-bit data path; tri-state controlled by OER/R/WR; electrically isolated from left port I/O |
| CEL / CER | Chip enable (left/right) | Active-low enables respective port; allows independent power-down of unused port to reduce ICC |
| OEL / OER | Output enable (left/right) | Active-low controls output drivers; enables high-impedance state during contention or write cycles |
| R/WL / R/WR | Read/write control (left/right) | Active-low write enable; high = read; supports non-overlapping or overlapping cycle timing |
| SEML / SEMR | Semaphore enable (left/right) | Active-low selects semaphore register access (A0–A2 address semaphore flags); decouples flag management from main RAM |
| INTL / INTR | Interrupt flag (left/right) | Open-drain outputs; asserted low to signal event completion or flag acquisition to host processor |
| BUSYL / BUSYR | Busy flag (left/right) | Push-pull outputs (Master) or inputs (Slave); indicates port contention or arbitration wait state |
| M/S | Master/Slave select | High = BUSY output (Master); Low = BUSY input (Slave); enables daisy-chained multi-device configurations |
| VCC / GND | Power supply | Eight VCC and eight GND pins distributed across package perimeter to minimize IR drop and ground bounce |
Key Features
| Feature | Design Value |

Applications
| Real-Time Inter-Processor Communication | Digital Signal Processing Buffering |
|---|---|
Use Scenario: Two independent DSPs exchange filter coefficients and processed audio frames via shared memory. IC Role / Device Role / Timing Role: Dual-port SRAM acts as zero-latency mailbox; left port serves DSP-A, right port serves DSP-B. Use Value: Eliminates software polling or interrupt overhead; 20 ns access ensures sub-microsecond inter-core synchronization. |
Use Scenario: An FPGA-based FFT engine streams incoming sensor samples into one port while reading transformed results from the other. IC Role / Device Role / Timing Role: Memory buffer decouples variable-rate input capture from fixed-rate computation pipeline. Use Value: Prevents pipeline stalls; BUSY flag prevents overwrites during concurrent read/write to same address. |
| Industrial PLC Data Exchange | Avionics System Health Monitoring |
Use Scenario: PLC CPU and motion controller share I/O status, setpoints, and fault logs in real time. IC Role / Device Role / Timing Role: Acts as deterministic shared memory with hardware semaphore for resource locking. Use Value: Guarantees atomic updates to critical variables; 1 mW standby enables low-power watchdog monitoring during idle cycles. |
Use Scenario: Flight computer and redundant health monitor exchange telemetry and diagnostic flags across isolated buses. IC Role / Device Role / Timing Role: Provides radiation-tolerant (200 V ESD rated), temperature-hardened memory for safety-critical data staging. Use Value: 2 V data retention preserves last-known-good state during transient power faults; INTL/INTR flags trigger immediate fault escalation. |
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-20AXC | 20 ns access, 16K × 16 organization, 3.3 V core (5 V tolerant I/O), 100-pin TQFP | Wider data bus; requires voltage translation or 3.3 V system integration; larger footprint | Select when 16-bit word width and lower active power (120 mW typ) outweigh package size and voltage compatibility constraints. |
| AS7C31025B-20TIN | 20 ns access, 128K × 8 organization, 3.3 V only, 54-pin TSOP-II | Higher density but incompatible voltage; no BUSY/semaphore logic; no industrial temp rating | Choose only for cost-sensitive, non-critical commercial designs where arbitration logic is implemented externally and 3.3 V supply is available. |
Compared with CY7C024AV-20AXC and AS7C31025B-20TIN, the 7006L20PFGI8 uniquely delivers 5 V TTL compatibility, integrated BUSY/semaphore arbitration, and industrial temperature qualification in a compact 64-pin TQFP-making it irreplaceable for legacy 5 V real-time control systems requiring hardware-enforced coherency.

FAQ
What is the guaranteed maximum access time for 7006L20PFGI8 across its full operating temperature range?
The 7006L20PFGI8 guarantees a maximum access time of 20 ns over the full industrial temperature range of –40°C to +85°C, as specified in the AC Electrical Characteristics table for the "7006X20" speed grade under industrial conditions. This value applies to tAA, tACE, and tAOE parameters and is validated with VCC = 5.0 V ±10%.
Does 7006L20PFGI8 support true simultaneous read operations from both ports to the same memory address?
Yes, the 7006L20PFGI8 features true dual-port memory cells that allow simultaneous reads of the exact same memory location from both left and right ports without contention, arbitration delay, or data corruption-enabling lock-free status mirroring in multi-CPU systems.
How does the M/S pin affect BUSY signal behavior in 7006L20PFGI8?
When M/S = HIGH, 7006L20PFGI8 operates as a Master: BUSYL and BUSYR are push-pull outputs asserting active-high during port contention. When M/S = LOW, it operates as a Slave: BUSYL and BUSYR become inputs, allowing external BUSY signals from a Master device to gate local write operations.
Can 7006L20PFGI8 retain data during complete power loss, and what voltage is required?
Yes, the 7006L20PFGI8 supports battery backup data retention at VCC = 2.0 V minimum, with typical retention current below 4 µA. This allows the device to preserve memory contents during main power failure when backed by a coin cell or supercapacitor, as confirmed in the Data Retention Characteristics table.
What is the function of the SEM pins (SEML/SEMR) on 7006L20PFGI8, and how are they used?
SEML and SEMR enable access to the internal 8-bit semaphore register bank. When SEM = LOW and CE = HIGH, address bits A0–A2 select one of eight semaphore flags, and I/O0–I/O7 read/write the flag state-providing hardware-accelerated resource locking without consuming main RAM bandwidth or requiring software arbitration.
