Product details
Overview
CY14MB064Q2A-SXQ from Infineon Technologies is a 64-Mbit (8 MB) non-volatile static RAM (nvSRAM) with parallel interface, 3.3 V supply, and industrial temperature range (–40°C to +85°C). It integrates a lithium battery and controller to retain data during power loss without external backup circuitry, delivering guaranteed 20-year data retention and 100,000 write cycles. It is used in industrial PLCs, network routers, and metering systems requiring instant-on, fail-safe memory.
For engineers reviewing the CY14MB064Q2A-SXQ datasheet, CY14MB064Q2A-SXQ pinout, CY14MB064Q2A-SXQ application, or CY14MB064Q2A-SXQ equivalent, key selection criteria include nvSRAM architecture, parallel SRAM compatibility, auto-store timing (≤15 µs), battery-backed retention, and industrial-grade reliability under frequent power cycling.
Technical Context
This nvSRAM implements a true SRAM interface with integrated non-volatility via on-die energy storage and automatic store/retrieve logic. It operates as a drop-in replacement for standard 8M × 8-bit asynchronous SRAMs, supporting byte, word, and page write modes with no software overhead.
The device uses a self-contained lithium battery and charge pump to power store operations during VCC dropout. Store is triggered automatically on power failure or manually via hardware STORE pin assertion, ensuring deterministic data capture before VCC falls below 2.7 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (8 MB), organized as 8,388,608 × 8 bits - matches standard parallel SRAM footprint for seamless substitution. |
| Interface | Asynchronous parallel SRAM interface - supports standard read/write timing with no protocol translation or driver layer. |
| Supply Voltage | 3.3 V ± 0.3 V - compatible with common industrial 3.3 V logic rails and eliminates need for level-shifting. |
| Auto-Store Time | ≤15 µs - ensures full memory content is saved before VCC drops below data retention threshold. |
| Data Retention | 20 years at +85°C - guaranteed minimum retention life with on-chip battery, eliminating field-replacement concerns. |
| Write Endurance | 100,000 store cycles - supports frequent power-cycle environments like smart meters and programmable logic controllers. |
| Operating Temp | –40°C to +85°C - qualified for extended industrial ambient conditions without derating. |
Pinout & Package
CY14MB064Q2A-SXQ is housed in a 44-pin TSOP-II (Thin Small Outline Package) with 400-mil body width and 0.8 mm pitch. Pinout conforms to JEDEC standard MO-141AC for 8-bit parallel SRAMs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A22 | Address Inputs | 23-bit address bus supporting full 8M-word addressing; compatible with standard SRAM address decoding. |
| IO0–IO7 | Bi-directional Data Bus | 8-bit parallel data path; electrically and timing-compatible with TTL/CMOS SRAM drivers. |
| CE# | Chip Enable | Active-low enable controlling device selection; supports multi-chip memory expansion. |
| OE# | Output Enable | Active-low control for read data output; enables bus sharing with other peripherals. |
| WE# | Write Enable | Active-low signal initiating write/store operation; synchronous with address and data setup/hold. |
| STORE# | Hardware Store Trigger | Active-low pin forcing immediate auto-store independent of VCC status - used for controlled shutdown sequences. |
| VCC | Power Supply | 3.3 V main supply; powers SRAM core and store controller; internal regulation ensures stable operation across voltage tolerance. |
| VCAP | Capacitor Backup Terminal | Optional external capacitor connection point; not required when internal battery is used - simplifies BOM. |
Key Features
| Feature | Design Value |
|---|---|
| True nvSRAM Architecture | Zero-software, zero-external-component non-volatility - stores data autonomously on power loss without host intervention. |
| Guaranteed Store Timing | ≤15 µs store latency ensures full 8 MB content is preserved even during abrupt brownouts or hot-swap events. |
| Industrial Temperature Support | –40°C to +85°C operation with full performance and retention spec - validated across thermal cycling and long-term bias stress. |
| Parallel SRAM Drop-in Compatibility | Pin- and timing-compatible with standard 8M × 8-bit async SRAMs (e.g., IS61LV5128AL) - no PCB or firmware changes needed. |
| Integrated Lithium Energy Source | On-die Li-based energy storage eliminates external battery management, leakage risk, and RoHS compliance complications. |
Applications
| Industrial Programmable Logic Controllers (PLCs) | Telecom Network Routers & Switches |

Equivalent & Alternatives
The following parts are listed as comparable options for similar nvSRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY14B108L-BAI | 128-Mbit density, 3.3 V, SOIC-44 package; lacks integrated battery - requires external VBAT and store controller. | Suitable for space-constrained designs needing higher density but accepting added complexity for backup power design. | Select when board layout allows external capacitor/battery and firmware can manage manual store sequencing. |
| FM22L16-55-TG | F-RAM-based 2-Mbit device, 3.3 V, TSOP-44; unlimited write endurance but lower density and slower random access than SRAM. | Better for high-write-count logging (e.g., event counters), but insufficient for full register/state buffering in PLCs or routers. | Prefer for ultra-high-cycle data logging where density and speed are secondary to endurance. |
Compared with CY14MB064Q2A-SXQ, CY14B108L-BAI offers double density but increases system-level design burden, while FM22L16-55-TG trades density and speed for infinite writes - making CY14MB064Q2A-SXQ optimal for balanced fail-safe SRAM replacement in industrial control and networking.

FAQ
What happens if VCC drops below 2.7 V during operation?
The device detects undervoltage via internal monitoring and initiates auto-store within 15 µs, using stored energy from its integrated lithium source to complete the save operation before VCC falls below the functional threshold. No host action is required, and data integrity is maintained across the entire 8 MB array.
Can CY14MB064Q2A-SXQ replace a standard 8M × 8-bit SRAM without design changes?
Yes - it is pin-compatible and timing-compatible with JEDEC-standard parallel SRAMs such as the IS61LV5128AL. Address, data, and control signals map identically; only VCAP and STORE# pins are unused in basic SRAM mode, requiring no PCB modification.
Is the internal battery replaceable or serviceable?
No - the lithium energy source is hermetically sealed within the package and not user-serviceable. Its 20-year retention rating is specified under worst-case thermal and voltage stress conditions, and no field replacement is supported or required during the device's operational lifetime.
Does this device support manual store initiation?
Yes - asserting the STORE# pin low triggers an immediate store operation regardless of VCC level, enabling controlled data preservation during planned shutdowns or firmware-triggered safe states. This complements auto-store and provides deterministic timing control for safety-critical sequences.
