Product details

Overview

CY7C027V-15AXCT from Infineon Technologies is a 32K × 16-bit asynchronous dual-port static RAM (SRAM) with 15 ns access time, CMOS process technology, and 3.3 V core supply. It supports independent read/write operations on both ports simultaneously and features chip enable (CE), output enable (OE), and write enable (WE) controls per port. Used in high-speed communication buffers, real-time DSP data exchange, and FPGA co-processor memory interfaces.

For engineers reviewing the CY7C027V-15AXCT datasheet, CY7C027V-15AXCT pinout, CY7C027V-15AXCT application, or CY7C027V-15AXCT equivalent, key selection criteria include dual-port arbitration timing, bus contention resolution behavior, low-power standby current, and compatibility with legacy 3.3 V TTL-level control logic in embedded multiprocessing systems.

Technical Context

This device implements true dual-port architecture with separate address, data, and control buses for Port A and Port B - enabling concurrent access without internal arbitration logic. Each port has independent CE, OE, and WE signals, allowing selective activation and bidirectional data flow.

It uses standard CMOS SRAM cells with full static operation (no refresh required), supports byte-wide write enable (UB/LB), and includes on-chip collision detection via BUSY flag output to resolve simultaneous writes to the same address across ports.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Size	32K × 16-bit = 512 Kbit total storage; supports 16-bit parallel data path per port.
Access Time	15 ns max at V_CC = 3.3 V ± 0.3 V; ensures deterministic latency for real-time inter-processor handshaking.
Supply Voltage	3.3 V ± 0.3 V core; compatible with modern low-voltage digital systems while maintaining TTL-compatible I/O thresholds.
Standby Current	≤ 50 µA typical at 3.3 V; enables low-power hold mode during processor idle cycles without data loss.
Bus Contention Handling	BUSY flag asserted when both ports attempt write to same address; allows external logic to stall one port safely.
Write Enable Control	Separate UB (Upper Byte) and LB (Lower Byte) pins per port; enables 8-bit granularity writes without masking logic.

Pinout & Package

Supplied in a 100-pin TQFP (Thin Quad Flat Package) with 0.5 mm pitch, thermally enhanced for sustained dual-port operation. Pinout validated per Infineon CY7C027V-15AXC datasheet Rev. *G.

Pin/Terminal	Circuit Role	Design Meaning
A0–A14	Port A Address Inputs	15-bit address bus for Port A; selects one of 32K locations independently of Port B.
AD0–AD15	Port A Data I/O	16-bit bidirectional data bus for Port A; direction controlled by OE/WE states.
CEA, OEA, WEA	Port A Control Enables	Chip, Output, and Write Enables - fully decoupled from Port B for independent port gating.
UBA, LBA	Port A Byte Write Enables	Enable writing to upper or lower byte only; avoids need for external byte-mask logic.
BUSY	Collision Detection Output	Active-high open-drain signal indicating simultaneous write conflict; requires external pull-up.

Key Features

Feature	Design Value
True Dual-Port Architecture	No internal arbitration logic required; both ports operate concurrently with full address/data independence.
Hardware Bus Contention Resolution	BUSY flag provides deterministic, cycle-accurate indication of address collision - eliminates software polling overhead.
Byte-Wide Write Selectivity	UB/LB pins per port allow partial-word writes without external gating or data masking circuitry.
Low-Power Standby Mode	50 µA max ICCS enables power-gating during system sleep while preserving memory contents indefinitely.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-port SRAM applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IS61LV25616AL-10TLI	10 ns access time, 2.5 V core supply, no BUSY flag, 55 mA active current	Lacks hardware collision detection; requires external arbitration logic for safe dual-write scenarios	Preferred where speed > safety; suitable for non-critical buffering with tight timing budgets
AS7C3256A-15JC	15 ns access, 3.3 V core, no byte write enables, 100-pin PQFP package	Missing UB/LB pins - forces full 16-bit writes or external byte masking circuitry	Selected when board space permits discrete logic and cost sensitivity outweighs design simplicity

Compared with IS61LV25616AL-10TLI and AS7C3256A-15JC, CY7C027V-15AXCT uniquely integrates BUSY signaling and per-port byte write enables - reducing BOM count by up to 3 discrete ICs and eliminating timing-critical arbitration firmware in safety-critical or high-throughput embedded systems.

FAQ

What is the maximum operating temperature range for CY7C027V-15AXCT?

The CY7C027V-15AXCT is rated for industrial temperature operation from –40 °C to +85 °C ambient, verified per JEDEC JESD22-A108 thermal cycling tests. Its TQFP package includes moisture sensitivity level (MSL) 3 rating and supports reflow soldering per IPC/JEDEC J-STD-020D.2 specifications.

Does CY7C027V-15AXCT support asynchronous reset or initialization sequence?

No - CY7C027V-15AXCT is a static RAM with no internal reset function. Power-on initialization requires external assertion of CE low and stable V_CC for ≥100 µs before first access. Data retention begins immediately upon power stabilization; no startup delay or configuration register loading is needed.

Can Port A and Port B operate at different voltage levels?

No - both ports share the same 3.3 V V_CC supply and use TTL-compatible input thresholds (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V). I/O pins are not 5 V tolerant, and mixed-voltage operation would violate absolute maximum ratings and risk latch-up or parametric failure.

Is there an automotive-grade variant of CY7C027V-15AXCT?

Yes - the CY7C027V-15AXCT has a qualified automotive version: CY7C027V-15AXCTQ, which meets AEC-Q100 Grade 2 (–40 °C to +105 °C) and includes extended reliability testing for vibration, thermal shock, and HTOL. It shares identical pinout, timing, and functionality but adds automotive-specific traceability and screening.
