Product details
Overview
CY7C09179V-6AXC from Cypress Semiconductor is a 3.3V, 32K × 9 synchronous dual-port static RAM with true dual-port architecture enabling simultaneous independent read/write access to any memory location. It supports pipelined (100 MHz max) and flow-through (53 MHz max) modes, delivers 6.5 ns clock-to-data access in pipelined mode, and operates across commercial temperature range (0°C to +70°C) in a 100-pin TQFP package - used in high-speed inter-processor communication buffers and real-time DSP data exchange.
For engineers reviewing the CY7C09179V-6AXC datasheet, CY7C09179V-6AXC pinout, CY7C09179V-6AXC application, or CY7C09179V-6AXC equivalent, key selection criteria include dual-port timing coordination, burst counter behavior, CE0/CE1 power-down control logic, and x9 data width compatibility with 9-bit parity or extended data buses.
Technical Context
This device implements fully synchronous dual-port SRAM with independent clock domains per port (CLKL/CLKR), each supporting pipelined output registration (tCD2 = 6.5 ns) or flow-through bypass (tCD1 = 15 ns). Address strobes (ADSL/ADSR) load internal burst counters, which increment on CNTEN assertion and reset via CNTRST.
Chip enable logic requires coordinated CE0 (active-low) and CE1 (active-high) assertion per port for selection; misalignment powers down internal circuitry to 10 µA standby. FT/PIPE pins configure output path per port - HIGH enables pipelined operation with one-cycle output latency, LOW enables zero-latency flow-through mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 32K × 9 (294,912 bits), supporting 9-bit data bus with parity or extended I/O width |
| Max Clock Frequency (Pipelined) | 100 MHz - enables 10 ns cycle time for high-throughput buffer applications |
| Clock-to-Data Valid (tCD2) | 6.5 ns (max) - defines minimum latency from CLK rising edge to valid output in pipelined mode |
| Operating Current (ICC) | 175 mA (typical) - determines thermal budget and supply rail sizing at full speed |
| Standby Current (ISB3) | 10 µA (typical, both ports CMOS-level disabled) - critical for low-power idle states in battery-backed systems |
| Access Mode Support | Flow-through, pipelined, and burst - allows trade-off between latency (flow-through) and throughput (pipelined/burst) |
| Supply Voltage | 3.3 V ± 300 mV - mandates tight regulation and decoupling for stable dual-port timing |
Pinout & Package
Package: 100-pin Thin Quad Plastic Flatpack (TQFP), 14 mm × 14 mm, 0.5 mm pitch, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0L–A14L / A0R–A14R | Address Inputs | 15-bit address bus for 32K depth; left/right independence enables concurrent addressing |
| I/O0L–I/O8L / I/O0R–I/O8R | Bidirectional Data Bus | 9-bit parallel interface per port; supports byte-wide or parity-aware data transfers |
| CLKL / CLKR | Port-Specific Clock Input | Asynchronous clock domains allow independent timing control and domain bridging |
| CE0L/CE1L / CE0R/CE1R | Chip Enable Pair | Two-signal enable logic prevents partial activation; CE0 ≤ VIL AND CE1 ≥ VIH required per port |
| R/WL / R/WR | Read/Write Control | Active-HIGH read, active-LOW write - matches standard synchronous SRAM control conventions |
| OEL / OER | Output Enable | Asynchronous control of output drivers; enables tri-state management without clock dependency |
| FT/PIPEL / FT/PIPER | Mode Select | Per-port configuration of pipelined (HIGH) vs. flow-through (LOW) output path |
| ADSL / ADSR | Address Strobe | Loads current address into burst counter and qualifies external address access |
| CNTENL / CNTENR | Burst Counter Enable | Triggers auto-increment on clock edge; stalls when ADS or CNTRST asserted |
| CNTRSTL / CNTRSTR | Burst Counter Reset | Synchronously resets counter to zero; not gated by ADS or CNTEN |
Key Features
| Feature | Design Value |
|---|---|
| True Dual-Port Architecture | Enables concurrent read/write to same memory location - essential for lock-free inter-processor communication |
| Pipelined Output Mode | Registers output data to achieve 100 MHz operation and minimize cycle time (tCYC2 = 10 ns) |
| Independent Burst Counters | Each port maintains dedicated address counter for interleaved memory access without software overhead |
| Dual Chip Enable Logic | CE0/CE1 pairing reduces spurious activation risk and enables clean depth expansion across multiple devices |
| Automatic Power-Down | Asserting CE0 HIGH or CE1 LOW disables internal circuitry, reducing ICC to 10 µA without external control logic |
Applications
| Telecom Line Card Buffering | DSP Co-Processor Interface |
|---|---|
|
Use Scenario: High-speed packet buffering between line interface ASIC and network processor in 10G Ethernet line cards.

Use Value: 32K × 9 organization accommodates 9-bit header+payload alignment; pipelined mode sustains 100 MHz throughput for sustained 900 MB/s data transfer. |
Use Scenario: Real-time data exchange between main CPU and floating-point DSP in radar signal processing subsystems. IC Role / Device Role / Timing Role: Shared memory resource enabling zero-copy data sharing; left port driven by CPU, right port accessed by DSP DMA engine. Use Value: Simultaneous access eliminates arbitration delays; burst counter support accelerates FFT coefficient table reads with minimal address bus cycles. |
| Industrial PLC Communication Module | Medical Imaging Data Pipeline |
|
Use Scenario: Deterministic I/O data aggregation in modular PLC backplanes with distributed motion controllers. IC Role / Device Role / Timing Role: Memory-mapped register bank synchronized to deterministic scan cycle clocks on both master and slave sides. Use Value: Flow-through mode provides sub-20 ns access for time-critical status updates; CE0/CE1 gating ensures precise power sequencing during hot-swap events. |
Use Scenario: Pixel data staging between CT scanner front-end ADC array and reconstruction FPGA. IC Role / Device Role / Timing Role: High-bandwidth frame buffer accepting parallel 9-bit pixel streams from 16-channel ADCs while feeding 256-bit wide FFT engines.

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IDT70V9279L10PF | 3.3V, 32K × 9, 10 ns access, but uses single CE and lacks per-port burst counter | Requires external address generation logic for burst transfers; less suitable for autonomous DMA-driven interfaces | Select when system-level address control is centralized and latency tolerance exceeds 6.5 ns |
| ISSI IS61WV3209-10ML | 3.3V, 32K × 9, 10 ns access, no pipelined mode - flow-through only; lower ICC (125 mA typ) | Lacks pipelined output path and dual CE logic; simpler control but limited to 50 MHz max frequency | Select for cost-sensitive industrial controls where 100 MHz operation is unnecessary and power budget is constrained |
Compared with IDT70V9279L10PF and ISSI IS61WV3209-10ML, CY7C09179V-6AXC uniquely combines per-port pipelining, independent burst counters, and dual CE power gating - making it optimal for high-frequency, autonomous dual-processor data exchange where latency predictability and hardware-accelerated addressing are critical.

FAQ
What is the maximum operating frequency in pipelined mode for CY7C09179V-6AXC?
The CY7C09179V-6AXC supports up to 100 MHz in pipelined mode, corresponding to a 10 ns clock cycle time (tCYC2). This is validated under specified load conditions (Load 2, C = 5 pF) and requires proper termination and layout to maintain signal integrity at this rate.
Can both ports access the same memory location simultaneously, and what happens during concurrent writes?
Yes, both ports can simultaneously access the same memory location - reads are fully supported, and writes are permitted. However, when both ports write to the same address concurrently, the final stored value is indeterminate due to race conditions in the true dual-port cell; system-level arbitration is required to avoid data corruption.
How does the burst counter operate, and what triggers its reset?
The burst counter loads the current address on ADS assertion and increments on each rising CLK edge when CNTEN is LOW. It wraps automatically after reaching the end of the memory space. CNTRST asynchronously resets the counter to zero regardless of ADS or CNTEN state, providing deterministic restart capability for circular buffer applications.
Is CY7C09179V-6AXC compatible with 5V logic interfaces?
No - CY7C09179V-6AXC is strictly a 3.3V core and I/O device with VIH = 2.0 V and VIL = 0.8 V. Direct connection to 5V logic violates absolute maximum ratings and risks damage. Level-shifting circuitry is required for interoperability with 5V systems.
