Product details
Overview
CY7C027V-15AXIT from Infineon Technologies is a 32K × 16-bit asynchronous dual-port static RAM (SRAM) with 15 ns access time, 3.3 V core voltage, and industrial temperature range (–40°C to +85°C). It supports independent read/write operations on both ports, features bus contention protection, and is used in real-time communication buffers and FPGA co-processor memory interfaces.
For engineers reviewing the CY7C027V-15AXIT datasheet, CY7C027V-15AXIT pinout, CY7C027V-15AXIT application, or CY7C027V-15AXIT equivalent, key selection criteria include dual-port arbitration timing, 3.3 V I/O compatibility, bus-hold functionality, and industrial-grade reliability for embedded control systems.
Technical Context
This device implements true dual-port architecture with separate address, data, and control lines per port-enabling simultaneous access without internal arbitration logic. It uses CMOS process technology with TTL-compatible I/Os and includes chip enable (CE), output enable (OE), and write enable (WE) controls per port.
Internal bus contention resolution is handled via low-impedance drivers and built-in bus-hold circuitry on data lines, preventing floating states during port switching. The device lacks on-chip arbitration logic, requiring external semaphore management for conflict-free multi-master operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 32K × 16-bit = 64 KB total storage; supports 16-bit parallel data paths on both ports. |
| Access Time | 15 ns max at VCC = 3.3 V; ensures deterministic latency for real-time inter-processor communication. |
| Supply Voltage | 3.3 V ± 0.3 V core; compatible with modern low-voltage digital logic families and FPGA I/O banks. |
| Operating Temperature | –40°C to +85°C; qualified for industrial environments including motor control and networking equipment. |
| I/O Voltage Level | TTL-compatible inputs and outputs; eliminates need for level-shifting in mixed-voltage systems. |
| Bus-Hold Feature | Active on all I/O pins; maintains last valid logic state during tri-state transitions, reducing external pull-up requirements. |
| Power Dissipation | Typical 550 mW (active), 100 µW (standby); enables low-power operation in always-on buffer applications. |
Pinout & Package
Supplied in a 100-pin TQFP (Thin Quad Flat Package) with 0.5 mm pitch, lead-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A14 | Port A address inputs | 15-bit address bus for left-side port; selects one of 32K locations. |
| AD0–AD15 | Port A bidirectional data bus | 16-bit parallel interface; direction controlled by OEA and WEA. |
| CEA, OEA, WEA | Port A control enables | Chip, output, and write enables-fully independent from Port B controls. |
| B0–B14 | Port B address inputs | 15-bit address bus for right-side port; supports concurrent addressing with Port A. |
| BD0–BD15 | Port B bidirectional data bus | 16-bit parallel interface; isolated signal path prevents coupling between ports. |
| CEB, OEB, WEB | Port B control enables | Independent control logic allows asymmetric read/write scheduling between ports. |
| INTA, INTB | Interrupt outputs | Open-drain signals indicate bus contention or semaphore status; require external pull-up. |
Key Features
| Feature | Design Value |
|---|---|
| True dual-port architecture | Independent address/data/control buses per port enable zero-wait-state concurrent access without arbitration overhead. |
| Bus-hold on all I/Os | Eliminates need for external pull resistors on data and control lines, reducing BOM count and board space. |
| On-chip port arbitration support | INTA/INTB outputs simplify external semaphore implementation for multi-processor synchronization. |
| Low-power standby mode | 100 µW typical consumption preserves system energy budget during idle periods in battery-backed systems. |
| Industrial temperature grade | Validated operation across –40°C to +85°C ensures reliability in factory automation and transportation electronics. |
Applications
| Industrial PLC Data Exchange | FPGA-Based Video Frame Buffer |
|---|---|
|
Use Scenario: Two independent PLC CPUs share status and command data via shared memory. IC Role / Device Role / Timing Role: Dual-port SRAM acts as non-blocking inter-CPU mailbox with deterministic 15 ns access. Use Value: Enables lock-free data exchange without software arbitration delays, improving cycle time predictability. |
Use Scenario: FPGA captures incoming video stream while simultaneously feeding display engine. IC Role / Device Role / Timing Role: Provides ping-pong frame buffering with independent read/write ports eliminating FIFO bottlenecks. Use Value: Sustains 60 fps HD video throughput without dropped frames or added pipeline latency. |
| Automotive ADAS Sensor Fusion | Telecom Packet Processing Buffer |
|
Use Scenario: Radar and camera processors exchange pre-processed object lists in real time. IC Role / Device Role / Timing Role: Shared memory node synchronizing heterogeneous sensor processors with sub-microsecond latency. Use Value: Reduces sensor fusion decision latency by avoiding serial message passing over CAN or Ethernet. |
Use Scenario: Network processor writes packet headers while security engine reads and verifies them. IC Role / Device Role / Timing Role: High-speed scratchpad for header metadata, decoupling packet ingress/egress pipelines. Use Value: Increases packet throughput by enabling parallel header inspection and forwarding operations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C027V-20AXI | 20 ns access time; otherwise identical pinout, voltage, and feature set. | Suitable where timing margin allows relaxed speed grade; lower cost in high-volume production. | Select when system clock domain permits 20 ns latency and cost optimization is prioritized. |
| IS61LV51216AL-10TLI | 10 ns access time; 3.3 V only; no bus-hold; different pinout (119-pin TSOP-II). | Requires PCB redesign and external pull-ups; better for ultra-low-latency designs with layout flexibility. | Choose only if 10 ns access is mandatory and board revision supports TSOP-II footprint and I/O conditioning. |
Compared with CY7C027V-15AXIT, the -20AXI offers cost savings at minor timing penalty, while the IS61LV51216AL-10TLI delivers faster access but demands hardware redesign and loses bus-hold convenience.

FAQ
What is the maximum clock frequency supported by CY7C027V-15AXIT?
CY7C027V-15AXIT is an asynchronous SRAM and does not use a clock signal. Its performance is defined by access time (15 ns) and cycle time (25 ns), not clock frequency. System timing must meet setup/hold requirements relative to CE/OE/WE edges-not a synchronous clock domain.
Does CY7C027V-15AXIT support byte-level write enable?
No. CY7C027V-15AXIT provides full 16-bit word-wide write enable per port (WEA/WEB). It lacks individual byte-write controls (e.g., UB/LB pins), so all 16 bits of a location are written simultaneously during each write cycle.
Can CY7C027V-15AXIT operate at 2.5 V?
No. The device is specified only for 3.3 V ±0.3 V (3.0 V to 3.6 V). Operation outside this range violates datasheet specifications and may cause data corruption, timing violations, or permanent damage. It is not 2.5 V tolerant.
Is there an automotive-grade version of CY7C027V-15AXIT?
No. CY7C027V-15AXIT is rated for industrial temperature (–40°C to +85°C) and is not AEC-Q100 qualified. Infineon does not offer an automotive-grade variant of this specific part number; alternative solutions would require redesign to a qualified QM or Grade 2 device.
