Product details

Overview

CY7C024E-25AXCT from Infineon Technologies is a 64K × 16-bit asynchronous dual-port static RAM (SRAM) with 25 ns access time, CMOS process technology, and 3.3 V core supply. It supports independent concurrent read/write operations on both ports, features bus contention protection, and is used in high-speed communications buffers, FPGA co-processor memory, and real-time industrial control data exchange.

For engineers reviewing the CY7C024E-25AXCT datasheet, CY7C024E-25AXCT pinout, CY7C024E-25AXCT application, or CY7C024E-25AXCT equivalent, key selection criteria include dual-port arbitration timing, 3.3 V I/O compatibility, byte-wide write enable control, and commercial temperature range operation.

Technical Context

This device implements true dual-port architecture with separate address, data, and control lines for each port, enabling simultaneous access without internal arbitration logic. It uses standard CMOS circuitry with TTL-compatible inputs and outputs, and includes chip select (CE1/CE2), output enable (OE1/OE2), and write enable (WE1/WE2) per port.

Internal bus contention resolution is handled via low-impedance drivers and automatic three-state control during conflicting accesses. The part operates over 0°C to +70°C and requires no external refresh, making it suitable for deterministic latency-critical systems where SRAM persistence and cycle predictability are essential.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Size	64K × 16-bit (1 Mbit total); provides full word-width parallel interface for microcontroller or FPGA data coupling.
Access Time	25 ns max at V_CC = 3.3 V ± 0.3 V; guarantees deterministic read latency for real-time control loops.
Supply Voltage	3.3 V core (V_CC), 3.3 V I/O (V_DDQ); eliminates level-shifting requirements in modern 3.3 V system designs.
Operating Temperature	0°C to +70°C; validated for commercial-grade embedded applications without extended thermal derating.
Power Dissipation	180 mW typical active power; enables use in thermally constrained PCB layouts without forced cooling.
Write Cycle Time	25 ns min; matches access time for synchronous burst-free write operations across both ports.

Pinout & Package

Supplied in a 100-pin TQFP (Thin Quad Flat Package) with 0.5 mm pitch, lead-free and RoHS-compliant. Pin mapping follows industry-standard dual-port SRAM layout with mirrored address/data groups per port and dedicated control signals.

Pin/Terminal	Circuit Role	Design Meaning
A0–A15 (Port A)	Address Input (Port A)	16-bit address bus for Port A; selects one of 64K locations independently of Port B.
A0–A15 (Port B)	Address Input (Port B)	16-bit address bus for Port B; enables fully independent addressing and concurrent access.
DQ0–DQ15 (Port A)	Data I/O (Port A)	16-bit bidirectional data path for Port A; three-stated when OE1 = HIGH or CE1 = HIGH.
DQ0–DQ15 (Port B)	Data I/O (Port B)	16-bit bidirectional data path for Port B; isolated from Port A data bus except during bus contention.
CE1, CE2	Chip Enable (Per Port)	Active-low enables for respective ports; allows independent power gating and port disable.
OE1, OE2	Output Enable (Per Port)	Controls tri-state of DQ lines per port; enables shared bus usage without external multiplexing.
WE1, WE2	Write Enable (Per Port)	Active-low write strobes; determines direction (read vs. write) and initiates write cycle timing.
BUSY	Bus Contention Indicator	Open-drain output asserted LOW during internal bus conflict; used to stall external controllers.

Key Features

Feature	Design Value
True Dual-Port Architecture	Independent address/data/control per port enables zero-wait-state concurrent read/write without arbitration logic.
On-Chip Bus Contention Resolution	Automatic BUSY signal generation and internal driver isolation prevent data corruption during simultaneous writes.
Byte Write Control (UB/LB)	Separate upper/lower byte write enables allow 8-bit granularity writes without masking logic or extra cycles.
TTL-Compatible I/O	Inputs accept 2.0 V min HIGH; outputs drive 2.4 V min at I_OH = –2.0 mA - interoperable with legacy 3.3 V logic families.
Low-Power Standby Mode	100 µA max standby current at V_CC = 3.3 V; supports energy-efficient idle states in battery-backed systems.

Applications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IS61LV51216AL-10TLI	10 ns access time, 3.3 V only, no BUSY pin, 512K × 16-bit density	Higher speed but lacks bus contention detection; requires external arbitration in multi-master systems	Select when deterministic sub-10 ns latency is required and external conflict management is acceptable
AS7C3256A-25JCIN	25 ns access, 32K × 16-bit, 3.3 V/2.5 V dual I/O support, no UB/LB pins	Lower density and no byte-write control; simpler interface but less flexible for partial-word updates	Choose for cost-sensitive designs where full-word writes suffice and footprint constraints favor smaller package

Compared with IS61LV51216AL-10TLI and AS7C3256A-25JCIN, CY7C024E-25AXCT uniquely balances 25 ns timing, integrated BUSY signaling, and byte-select capability-making it optimal for systems requiring robust concurrent access without external glue logic.

FAQ

What is the maximum clock frequency supported by CY7C024E-25AXCT?

CY7C024E-25AXCT is an asynchronous SRAM and does not use a clock signal. Its performance is defined by access time (25 ns) and cycle time (25 ns), meaning it supports up to 40 MHz effective throughput per port when operated under worst-case timing conditions with proper setup/hold margins.

Does CY7C024E-25AXCT support 2.5 V I/O operation?

No. CY7C024E-25AXCT requires 3.3 V ± 0.3 V for both V_CC (core) and V_DDQ (I/O). It is not rated for 2.5 V operation, and applying 2.5 V to V_DDQ may result in unreliable output drive strength or timing violations.

How is bus contention resolved when both ports attempt to write simultaneously?

The device asserts the open-drain BUSY pin LOW during internal bus contention. External logic must monitor BUSY and stall the write cycle on the affected port until BUSY returns HIGH, ensuring data integrity without requiring external arbitration circuitry.

Can CY7C024E-25AXCT be used in automotive applications?

CY7C024E-25AXCT is specified for commercial temperature range (0°C to +70°C) and is not AEC-Q100 qualified. It is not recommended for under-hood automotive applications but may be used in cabin-infotainment or gateway modules with controlled thermal environments.
