Product details
Overview
CY7C006AV-25AXC from Infineon Technologies (formerly Cypress) is a 3.3 V, 16 K × 8 asynchronous dual-port static RAM with true dual-ported architecture enabling simultaneous read/write access to the same memory location, 25 ns access time, 115 mA typical active current, and 10 µA typical standby current in ISB3 mode. It is used in interprocessor communication buffers and real-time video frame storage where deterministic port arbitration and mailbox-based messaging are required.
For engineers reviewing the CY7C006AV-25AXC datasheet, CY7C006AV-25AXC pinout, CY7C006AV-25AXC application, or CY7C006AV-25AXC equivalent, key selection considerations include its 64-pin TQFP package, master/slave expandability for 16-bit bus width, on-chip semaphore latches, BUSY/INT signaling for contention resolution, and CMOS-level standby power efficiency.
Technical Context
The CY7C006AV implements fully asynchronous dual-port operation with independent left/right address buses (A0L–A13L / A0R–A13R), control signals (CEL/CER, R/WL/R/WR, OEL/OER), and dedicated arbitration logic. Its 16 K × 8 organization maps to 32,768 bytes with two 16-bit mailbox addresses (3FFFR, 3FFEL) reserved for interrupt-driven message passing.
On-chip semaphores consist of eight independent latches accessible via SEML/SEMR pins, with A0–A2 selecting latch index; each latch enforces mutual exclusion by allowing write control only to the side that first writes '0'. The M/S pin configures BUSY as output (master) or input (slave), enabling daisy-chained expansion without external logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 16 K × 8 = 131,072 bits; supports full 16-bit word addressing via A0–A13 on both ports |
| Access Time | 25 ns maximum; guarantees data valid at outputs within 25 ns after CE or OE assertion |
| Supply Voltage | 3.3 V ± 0.3 V; compatible with LVCMOS I/O interfaces and low-power embedded systems |
| Active Current | 115 mA typical (ICC); enables high-throughput burst transfers without thermal throttling |
| Standby Current | 10 µA typical (ISB3); achieved when both ports driven to CMOS levels, critical for battery-backed operation |
| Arbitration Latency | tBLA = 10 ns (address-match), tBLC = 15 ns (CE-driven); defines minimum timing window for deterministic BUSY assertion |
| Semaphore Access Delay | tSOP = 10 ns min between SEM deassertion and read attempt; ensures latch state stabilization before sampling |
Pinout & Package
Package: 64-pin thin quad flat pack (TQFP), 10 mm × 10 mm body, 0.5 mm pitch, Pb-free compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CEL / CER | Chip Enable (Left / Right) | Active-low enable for respective port; controls automatic power-down when deasserted |
| R/WL / R/WR | Read/Write Control (Left / Right) | High = read, low = write; determines direction of data flow on I/OxL/I/OxR lines |
| OEL / OER | Output Enable (Left / Right) | Active-low; gates output drivers to prevent bus contention during inactive cycles |
| A0L–A13L / A0R–A13R | Address Inputs (Left / Right) | 14-bit address bus per port; selects one of 16,384 memory locations independently |
| I/O0L–I/O7L / I/O0R–I/O7R | Data Bus (Left / Right) | 8-bit bidirectional data path; supports simultaneous read/write across ports |
| SEML / SEMR | Semaphore Enable (Left / Right) | Active-low chip select for 8 semaphore latches; overrides CEL/CER during semaphore access |
| INTL / INTR | Interrupt Flag (Left / Right) | Open-drain output; asserted when opposite port writes to mailbox (3FFEL/3FFFR) |
| BUSYL / BUSYR | Busy Flag (Left / Right) | Configurable I/O: output in master mode, input in slave mode; signals arbitration conflict |
| M/S | Master/Slave Select | High = master (BUSY outputs), low = slave (BUSY inputs); enables cascaded 16-bit bus expansion |
| VCC / GND | Power / Ground | 3.3 V supply and reference; decoupling required per JEDEC standards for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| True Dual-Port Architecture | Enables concurrent read/write to identical memory addresses without external arbitration logic |
| Hardware Semaphore Latches | Eight dedicated, mutually exclusive latches accessible via SEML/SEMR; eliminate software polling overhead |
| Mailbox-Based Interrupts | Two reserved upper addresses (3FFFR, 3FFEL) trigger INTL/INTR on write, enabling zero-latency inter-processor signaling |
| Master/Slave Expandability | M/S pin configures BUSY as output/input, allowing up to 16-bit data bus expansion using multiple devices without glue logic |
| Low-Power Standby Mode | 10 µA ISB3 current achieved with CMOS-level CE deassertion on both ports-suitable for always-on edge nodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IDT70V27L25PF | 5 V tolerant, 25 ns access, 8 K × 16 organization; no integrated semaphores or mailbox interrupts | Requires external logic for semaphore emulation and interrupt generation; suited for legacy 5 V systems | Select when upgrading from older IDT designs or when 16-bit native bus width is mandatory |
| ISSI IS61WV102416BLL-10TLI | 3.3 V, 1024 K × 16 sync burst SRAM; no dual-port architecture-requires external arbiter for multi-CPU use | Higher density but lacks true concurrency; suitable for single-processor cache extension, not inter-processor comms | Choose only if memory bandwidth >200 MB/s is needed and arbitration can be handled in FPGA fabric |
Compared with IDT70V27L25PF and IS61WV102416BLL-10TLI, the CY7C006AV-25AXC uniquely delivers integrated arbitration, semaphores, and mailbox interrupts in a 3.3 V, 25 ns dual-port package-making it irreplaceable for deterministic real-time interprocessor communication without added logic.

FAQ
What is the difference between CY7C006AV and CY7C144AV?
The CY7C006AV provides 16 K × 8 (131,072-bit) memory organization with A0–A13 addressing on both ports, while the CY7C144AV offers 8 K × 8 (65,536-bit) capacity using A0–A12. Both share identical pinout, timing (25 ns), and feature set including semaphores, interrupts, and master/slave configuration-only memory depth differs.
How does the BUSY signal resolve memory contention?
When both ports assert CE and target the same address within tPS (15 ns), internal arbitration asserts BUSYL or BUSYR within tBLA (10 ns) to block the losing port. The blocked port must wait until BUSY deasserts before retrying-ensuring deterministic, hardware-governed access order without software intervention.
Can the CY7C006AV operate with mixed voltage I/O?
No. The CY7C006AV is strictly a 3.3 V core and I/O device. Its absolute maximum ratings specify –0.5 V to +4.6 V on inputs, but DC electrical characteristics (VIH/VIL, VOH/VOL) are specified only for 3.3 V operation with TTL- or CMOS-compatible thresholds-no 5 V tolerance or level-shifting capability is provided.
Is the M/S pin required for standalone operation?
No. The M/S pin is optional and defaults to master mode (BUSY outputs) when left unconnected or pulled HIGH. It is only needed when expanding data width beyond 8 bits using multiple CY7C006AV devices in master/slave configuration-standalone 8-bit operation requires no M/S connection.
