Product details
Overview
CY7C006A-15AXC from Cypress Semiconductor is a 16K × 8 true dual-port static RAM with independent left/right ports, 15 ns access time, 5 V supply, and integrated arbitration logic for interprocessor communication. It supports simultaneous read/write to the same memory location using BUSY flags and enables software handshaking via semaphores and INT pins in embedded multi-CPU systems.
For engineers reviewing the CY7C006A-15AXC datasheet, CY7C006A-15AXC pinout, CY7C006A-15AXC application, or CY7C006A-15AXC equivalent, key selection criteria include asynchronous dual-port timing, master/slave expandability, CMOS-level standby current (0.05 mA), and PLCC/TQFP package compatibility for legacy industrial control and video buffer designs.
Technical Context
This device implements fully asynchronous dual-port SRAM architecture with separate address, data, and control buses per port (A0L–A13L/I/O0L–I/O7L/CEL/OEL/R/WL on left; A0R–A13R/I/O0R–I/O7R/CER/OER/R/WR on right). On-chip arbitration resolves contention via BUSYL/BUSYR signals with tBLA = 4 ns and tBLC = 5 ns response latency.
Semaphore logic includes eight dedicated latches accessible via SEML/SEMR with tSOP = 10 ns setup and tSWRD + tDOE = 15 ns read delay. Interrupts use fixed mailbox addresses (7FFEL, 7FFFR) with automatic reset-on-read behavior and BUSY-gated assertion to prevent race conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 16K × 8 bits (131,072 total bits), addressing via A0L–A13L and A0R–A13R |
| Access Time | 15 ns maximum (tACE), enabling 66.7 MHz synchronous interface clocking |
| Supply Voltage | 5 V ±10%, compatible with legacy TTL/CMOS logic families without level shifters |
| Standby Current | 0.05 mA typical (ISB3) at CMOS-level CE disable, critical for low-power idle states |
| Operating Current | 180 mA typical (ICC), defining thermal budget for dense PCB layouts |
| I/O Voltage Levels | VIH = 2.2 V, VIL = 0.8 V - ensures noise margin >0.4 V in industrial EMI environments |
| Input Capacitance | 10 pF max (CIN), limiting trace length to ≤10 cm for signal integrity at 15 ns edges |
Pinout & Package
Available in 68-pin PLCC (standard) and 64-pin TQFP; both packages support full dual-port functionality with identical pin mapping except for NC placements. Thermal pad not present; power dissipation managed via VCC/GND pin pairs distributed across perimeter.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CEL / CER | Chip Enable (Left/Right) | Independent port activation; CE HIGH disables output drivers and triggers ISB3 power-down mode |
| OEL / OER | Output Enable (Left/Right) | Gates I/O bus drivers; allows read operation while CE remains active for arbitration readiness |
| R/WL / R/WR | Read/Write Control (Left/Right) | Active-HIGH write strobe; rising edge samples data for write, falling edge initiates read output enable |
| SEML / SEMR | Semaphore Enable (Left/Right) | Activates 3-bit semaphore address decoding (A0–A2); overrides normal memory access when asserted |
| INTL / INTR | Interrupt Flag (Left/Right) | Open-drain output signaling mailbox write; requires external pull-up for interrupt controller interfacing |
| BUSYL / BUSYR | Arbitration Status (Left/Right) | Indicates port contention: HIGH = blocked access, LOW = granted memory access |
| M/S | Master/Slave Select | HIGH = BUSY outputs drive slave devices; LOW = BUSY inputs accept arbitration signals from master |
| A0L–A13L / A0R–A13R | Address Bus (Left/Right) | 14-bit parallel address path; no internal multiplexing - supports burst-free random access |
| I/O0L–I/O7L / I/O0R–I/O7R | Data Bus (Left/Right) | 8-bit bidirectional I/O; tristate-controlled per port to prevent bus conflicts during arbitration |
Key Features
| Feature | Design Value |
|---|---|
| True Dual-Port Architecture | Simultaneous independent read/write to identical memory locations without external logic or wait states |
| On-Chip Arbitration Logic | Hardware-resolved contention with deterministic BUSY assertion timing (tBLA/tBLC), eliminating software polling overhead |
| Dedicated Semaphore Latches | Eight hardware-managed resource locks with atomic set/clear semantics for cross-processor synchronization |
| Configurable Master/Slave Mode | M/S pin enables 16-bit+ data bus expansion using multiple CY7C006A-15AXC devices without discrete glue logic |
| Automatic Power-Down | Per-port CE control reduces ICC to ISB3 (0.05 mA) when inactive - critical for battery-backed systems |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IDT70V25L15PF | 32K × 8 organization, 3.3 V supply, 15 ns access, LVDS-compatible I/O | Requires level-shifting for 5 V systems; higher density but incompatible voltage rail | Select only if migrating to 3.3 V infrastructure and needing larger memory footprint |
| CY7C028V-15AC | 128K × 16 organization, 5 V supply, 15 ns access, 100-pin TQFP | Higher pin count and board space; lacks M/S pin for simple width expansion | Choose when 16-bit data path and >128K capacity are mandatory; verify PCB layout impact |

FAQ
What is the function of the M/S pin in CY7C006A-15AXC?
The M/S pin configures the device as master (M/S = HIGH) or slave (M/S = LOW). In master mode, BUSYL/BUSYR are outputs driving slave BUSY inputs; in slave mode, they become inputs accepting arbitration signals. This enables 16-bit+ data bus expansion using multiple CY7C006A-15AXC chips without external logic.
How does semaphore operation prevent resource conflicts between ports?
Semaphores use eight dedicated latches accessed via SEML/SEMR. Writing '0' to a semaphore grants exclusive control; reading returns '0' if acquired or '1' if contested. The latch state is mirrored across ports, ensuring atomic ownership transfer with tSOP = 10 ns setup and tSWRD + tDOE = 15 ns read delay - preventing race conditions during shared peripheral access.
Can CY7C006A-15AXC operate with mixed voltage interfaces (e.g., 3.3 V processor + 5 V RAM)?
No - CY7C006A-15AXC requires 5 V ±10% VCC and specifies VIH = 2.2 V, VIL = 0.8 V. Direct connection to 3.3 V logic violates input voltage limits and risks damage. Level-shifting circuitry (e.g., TXB0304) is mandatory for interfacing with 3.3 V controllers, adding propagation delay and board area.
What happens during simultaneous access to the same memory location by both ports?
On-chip arbitration asserts BUSYL/BUSYR within tBLA = 4 ns (address match) or tBLC = 5 ns (CE assertion). The winning port gains immediate access; the losing port's BUSY flag goes HIGH, blocking its R/W cycle until arbitration completes. Data integrity is preserved - no corruption occurs, and the losing port retries automatically upon BUSY deassertion.
