Product details
Overview
CY14ME064Q2A-SXQ from Infineon Technologies is a 64-Mbit (8 MB) nvSRAM (non-volatile static RAM) with automatic store/restore, 2.7–3.6 V supply voltage, 15 ns access time, and SOIC-44 package. It functions as a drop-in SRAM replacement with battery-free non-volatility for mission-critical data logging in industrial control systems.
For engineers reviewing the CY14ME064Q2A-SXQ datasheet, CY14ME064Q2A-SXQ pinout, CY14ME064Q2A-SXQ application, or CY14ME064Q2A-SXQ equivalent, key selection criteria include automatic hardware store timing (≤100 µs), unlimited SRAM read/write endurance, 20-year data retention at +85°C, and compatibility with standard parallel SRAM bus protocols.
Technical Context
This nvSRAM integrates a fast 64-Mbit SRAM core with on-chip SONOS non-volatile storage and autonomous store/restore logic. It operates in asynchronous mode with CE#, OE#, and WE# control signals and supports both transparent store (on power loss) and software store commands.
The device uses an internal voltage detector to trigger store when VCC drops below 2.7 V, capturing SRAM contents into non-volatile memory without external circuitry. Restore occurs automatically on power-up, completing within 15 ms before the device enters active SRAM mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Type | nvSRAM (non-volatile SRAM) with integrated SONOS storage - eliminates need for external battery or capacitor backup. |
| Capacity | 64 Mbit (8 MB) organized as 8,388,608 × 8 - matches standard parallel SRAM footprint for direct replacement. |
| Access Time | 15 ns at VCC = 3.3 V - ensures compatibility with high-speed microcontroller and FPGA SRAM interfaces. |
| Supply Voltage | 2.7–3.6 V - supports wide industrial input rails and simplifies power design vs. dual-supply alternatives. |
| Store Time | ≤100 µs (typical) - guarantees full SRAM content capture before VCC falls below functional threshold. |
| Data Retention | 20 years at +85°C - validated non-volatile retention without refresh, critical for unattended equipment. |
| Endurance | Unlimited SRAM read/write cycles - no wear-out mechanism during volatile operation. |
Pinout & Package
Package: 44-pin SOIC (300 mil width), RoHS-compliant, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address inputs | 21-bit address bus supporting full 8-MB addressing space; compatible with standard SRAM address mapping. |
| DQ0–DQ7 | Data I/O lines | 8-bit bidirectional data bus; TTL-compatible levels with 3-state output control via OE# and WE#. |
| CE# | Chip enable | Active-low chip select; enables device only when asserted, reducing standby current to 20 µA typical. |
| OE# | Output enable | Controls data bus drivers during read operations; allows multiplexed bus sharing with other peripherals. |
| WE# | Write enable | Controls write cycle initiation; low during SRAM writes and software store command execution. |
| VCC / VSS | Power / ground | Single 2.7–3.6 V supply; no auxiliary VCAP or backup battery required due to integrated non-volatile storage. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic Hardware Store | Triggered by internal voltage monitor on VCC drop - no firmware intervention or external components needed. |
| Software Store Command | Issued via standard write sequence (A0=0, A1=1, A2=0, etc.) - enables deterministic, user-controlled non-volatile save points. |
| Restore-on-Power-Up | Auto-restores last stored image within 15 ms after VCC exceeds 2.7 V - ensures deterministic boot state. |
| Industrial Temperature Range | –40°C to +85°C - qualified for extended operation in PLCs, motor drives, and factory automation hardware. |
| JEDEC Standard Pinout | SOIC-44 footprint identical to industry-standard 8-MB parallel SRAMs - enables drop-in PCB replacement. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar nvSRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY14V108L-BAI | 8-MB nvSRAM in 48-pin TSOPII package; 25 ns access time; supports 2.2–3.6 V supply. | Requires PCB redesign due to different package and pinout; lower speed margin may limit use with >40 MHz bus clocks. | Select when board layout allows TSOPII footprint and wider voltage tolerance (2.2 V min) is required. |
| FM22L16-40-TG | 2-MB F-RAM with 45 ns access; SOIC-44; 3.0–3.6 V; unlimited endurance but lower density and slower access. | Lacks automatic store/restore logic; requires external controller intervention for non-volatile save operations. | Choose where ultra-high endurance (>10¹⁴ cycles) outweighs need for autonomous power-loss protection. |
Compared with CY14V108L-BAI and FM22L16-40-TG, CY14ME064Q2A-SXQ uniquely delivers 15 ns access, automatic hardware store, and full 8-MB capacity in a JEDEC-standard SOIC-44 - making it optimal for high-speed industrial control systems requiring zero-firmware, zero-component non-volatility.

FAQ
Does CY14ME064Q2A-SXQ require an external capacitor or battery for non-volatile operation?
No. The device integrates SONOS-based non-volatile storage and autonomous store/restore logic, eliminating all external backup components. Store is triggered internally when VCC drops below 2.7 V, and restore completes within 15 ms on power-up.
Can CY14ME064Q2A-SXQ be used as a direct replacement for standard 8-MB parallel SRAMs?
Yes. It uses a JEDEC-standard SOIC-44 package with identical pinout and timing behavior to common 8-MB asynchronous SRAMs (e.g., IS61LV5128AL). No PCB or firmware changes are needed beyond confirming VCC range compatibility (2.7–3.6 V).
What is the maximum operating temperature and qualification status for automotive use?
The device is rated for –40°C to +85°C and is not AEC-Q100 qualified. It is intended for industrial applications; for automotive deployment, Infineon offers the pin-compatible CY14ME064Q2A-SP version with AEC-Q100 Grade 2 qualification.
How does software store differ from automatic store, and when should each be used?
Software store is initiated by a specific address/data write sequence and provides deterministic, user-controlled non-volatile saves (e.g., after critical configuration updates). Automatic store triggers on power loss and ensures no data loss during unexpected outages - both operate independently and can coexist.
