Product details

Overview

CY14ME064Q2A-SXIT from Infineon Technologies is a 64-Mbit (8 MB) nvSRAM (non-volatile static RAM) with automatic store/restore, 2.7–3.6 V supply, 15 ns access time, and industrial temperature range (–40°C to +85°C). It serves as a drop-in SRAM replacement with battery-free non-volatility in mission-critical data logging, network packet buffering, and real-time control systems requiring instant power-loss data retention.

For engineers reviewing the CY14ME064Q2A-SXIT datasheet, CY14ME064Q2A-SXIT pinout, CY14ME064Q2A-SXIT application, or CY14ME064Q2A-SXIT equivalent, key selection criteria include auto-store timing (≤100 µs), unlimited write endurance, SRAM-compatible parallel interface, and absence of external backup batteries or capacitors.

Technical Context

This nvSRAM integrates a 64-Mbit SRAM array with on-chip SONOS-based non-volatile storage and autonomous store/restore logic. It operates in standard asynchronous SRAM mode during normal read/write cycles and triggers automatic store upon V_CC dropout detection, completing data transfer to NV cells within 100 µs.

The device uses a 48-pin TSOP II (300-mil) package with x16 data bus width, supports CE#-controlled operation, and includes hardware store enable (HSB#) for optional manual store initiation. No external components are required for non-volatile functionality.

Use Value: Eliminates need for external FRAM or battery-backed SRAM, reducing BOM count and field failure risk from capacitor aging.

Use Scenario: Capturing sensor readings and machine state snapshots in programmable logic controllers during factory floor power glitches.

IC Role / Device Role / Timing Role: Non-volatile scratchpad memory holding last valid I/O cycle state for safe restart after brownout recovery.

Use Value: Ensures deterministic restore of operational context without software-initiated save routines or watchdog coordination.

Medical Imaging Control Memory

Equivalent & Alternatives

The following parts are listed as comparable options for similar non-volatile SRAM applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CY14V108L-BAI	8-Mbit density, SOIC-32 package, 20 ns access, 2.7–3.6 V - lower capacity, different pinout, no HSB# pin	Suitable for space-constrained designs where 8 MB is excessive and SOIC footprint is preferred	Select when board layout cannot accommodate TSOP II or requires smaller memory footprint
FM22L16-55-TG	2-Mbit F-RAM, 44-pin TSOP, 45 ns access, 3.0–3.6 V - faster write endurance but lower density and slower access	Better for high-frequency logging (e.g., >10 kHz sample rate) where write latency dominates over capacity	Select when application demands near-zero write latency and infinite endurance over density or speed

Compared with CY14ME064Q2A-SXIT, CY14V108L-BAI trades capacity and HSB# visibility for compact packaging, while FM22L16-55-TG sacrifices access speed and density for unlimited write cycles - making each optimal for distinct trade-off priorities: size, endurance, or performance.

FAQ

Does CY14ME064Q2A-SXIT require an external capacitor for non-volatile operation?

No. The device integrates a charge-pump circuit and SONOS non-volatile storage cells, enabling full automatic store/restore without any external capacitor, battery, or backup power source. This eliminates capacitor aging, leakage, and board space overhead associated with traditional battery-backed SRAM solutions.

Can CY14ME064Q2A-SXIT be used as a direct replacement for standard 512K × 16 SRAMs?

Yes. It is pin-compatible and timing-compatible with industry-standard asynchronous SRAMs in the same 48-pin TSOP II package. No changes to address/data bus routing, control signal timing, or firmware initialization are required - only V_CC and ground connections are needed for basic operation.

What happens during a rapid power-cycle event?

The device detects V_CC falling below 2.7 V and initiates store within 10 µs, completing transfer of all 64 Mbit within ≤100 µs. If V_CC recovers above 2.7 V before store completes, the operation continues uninterrupted. Restore occurs automatically on next power-up, with data available within 15 ns of V_CC stabilization.

Is HSB# pin necessary for normal operation?

No. HSB# is optional and used only for system-level monitoring of store/restore status. When left unconnected or pulled high, the device functions fully - HSB# simplifies diagnostics and synchronization in safety-critical systems but adds no functional dependency.
