Product details
Overview
CY14E116L-ZS25XIT from Infineon Technologies (formerly Cypress) is a 16-Mbit nonvolatile SRAM (nvSRAM) with ×8 organization (2048K × 8), 25-ns access time, 4.5–5.5 V operation, and TSOP II 44-pin package. It integrates QuantumTrap nonvolatile storage per cell, enabling automatic STORE on power-down and software/hardware-controlled RECALL. Used in industrial control modules requiring persistent memory without battery backup.
For engineers reviewing the CY14E116L-ZS25XIT datasheet, CY14E116L-ZS25XIT pinout, CY14E116L-ZS25XIT application, or CY14E116L-ZS25XIT equivalent, key selection criteria include AutoStore timing under voltage droop, HSB assertion behavior during STORE, sleep mode availability (not supported in this variant), and compatibility with 5-V legacy bus interfaces.
Technical Context
This nvSRAM combines a fast static RAM array (4096 × 4096) with parallel QuantumTrap nonvolatile elements, enabling bit-cell-level nonvolatility without external EEPROM or flash. STORE transfers data from SRAM to QuantumTrap using charge from VCAP; RECALL restores data on power-up via internal charge pump.
It operates in three modes: active (75 mA @ 45 ns), standby (650 µA), and - unlike the 165-ball FBGA variant - does not support Sleep mode (ZZ pin is NC in TSOP II). The device uses single CE architecture and supports hardware STORE via HSB pin assertion or automatic initiation at VCC dropout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16 Mbit (2048K × 8), providing 2 MB of byte-addressable nonvolatile RAM space. |
| Access Time | 25 ns - guarantees sub-25-ns read/write latency for real-time deterministic memory access. |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5-V TTL/CMOS bus systems and legacy industrial controllers. |
| Data Retention | 20 years at +85 °C - ensures long-term data integrity without refresh or backup power. |
| STORE Endurance | 1 million cycles to QuantumTrap - supports frequent power-cycle logging in telemetry and event-recorder applications. |
| Operating Temp | –40 °C to +85 °C - qualified for uncontrolled industrial environments including factory automation and transportation systems. |
| Active Current | 75 mA at 45 ns - defines worst-case dynamic power draw during burst reads/writes. |
Pinout & Package
Package: 44-pin Thin Small-Outline Package (TSOP II), 400-mil width, surface-mount, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address Input | 21-bit address bus for ×8 mode; selects one of 2,097,152 bytes; A20 is used only in full 16-Mbit addressing. |
| DQ0–DQ7 | Bidirectional Data I/O | 8-bit parallel data path; tristates when OE HIGH or CE HIGH; supports byte-wide legacy microprocessor interfaces. |
| CE | Chip Enable | Active-LOW single-enable signal; enables memory access when LOW; no CE1/CE2 dual-enable logic in TSOP II. |
| WE | Write Enable | Active-LOW control for write cycles; latches data on falling edge while CE and OE are asserted appropriately. |
| OE | Output Enable | Active-LOW control for output drivers; disables DQ outputs (tristate) when HIGH to prevent bus contention. |
| HSB | Hardware STORE Busy | Open-drain output indicating STORE progress (LOW); also accepts external LOW pulse to trigger STORE; requires pull-up resistor. |
| VCAP | AutoStore Capacitor Terminal | Connects external capacitor (typ. 4.7 µF tantalum) to sustain STORE during VCC dropout; critical for reliable power-fail capture. |
| VCC / VSS | Power / Ground | 5-V core supply and return; decoupling required near pins; VSS pins distributed across package for low-impedance grounding. |
Key Features
| Feature | Design Value |
|---|---|
| Hands-off AutoStore | Initiates nonvolatile STORE automatically at VCC dropout below threshold - eliminates firmware dependency for power-loss protection. |
| QuantumTrap Technology | Embedded nonvolatile element per SRAM cell enables infinite SRAM read/write cycles without degrading nonvolatile endurance. |
| Software STORE/RECALL | Controlled via specific address/data sequences - allows deterministic, timed persistence (e.g., after critical state update, before shutdown). |
| Hardware STORE Trigger | External LOW pulse on HSB initiates immediate STORE - enables system-level power monitoring circuits to force save on brownout detection. |
| Industrial Temperature Range | Validated operation from –40 °C to +85 °C - supports deployment in motor drives, PLC backplanes, and outdoor metering without derating. |
Applications
| Industrial PLC Data Logging | Medical Device Configuration Storage |

IC Role / Device Role / Timing Role: High-speed ring buffer with atomic STORE on voltage sag - preserves pre-failure context for root-cause analysis. Use Value: 1 million STORE cycles support continuous logging over 10+ years in always-on infrastructure; 5-V tolerance matches legacy telecom power rails. |
Use Scenario: Storing door lock sequence history, window position memory, and lighting profiles in 12-V automotive BCMs subject to load-dump transients. IC Role / Device Role / Timing Role: Power-loss-resilient parameter store interfaced directly to 8/16-bit MCU buses without level-shifting. Use Value: Qualified to –40 °C to +85 °C and immune to battery disconnect events - enables "last-action" recall after vehicle restart. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar nvSRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY14E116L-ZS35XIT | Slower 35-ns access time; identical 44-pin TSOP II package, 4.5–5.5 V, and QuantumTrap architecture. | Suitable where timing margin allows relaxed access; lower power consumption in active mode due to reduced drive strength. | Select for cost-sensitive designs where 35-ns latency is acceptable and board layout favors pin-compatible drop-in replacement. |
| FM16W08-25-SG | F-RAM-based 8-Mbit device (1024K × 8); 25-ns access; 3.3 V only; no VCAP requirement; unlimited endurance. | Lacks AutoStore on power-down - requires external voltage monitor and controlled STORE command; incompatible with 5-V systems. | Choose when system already uses 3.3-V rails and firmware can guarantee STORE execution prior to power loss; avoids capacitor placement and leakage concerns. |
Compared with CY14E116L-ZS35XIT, this 25-ns variant delivers tighter timing margins for high-throughput control loops; versus FM16W08-25-SG, it provides true hands-off power-fail STORE but demands VCAP design and operates only at 5 V.

FAQ
What is the role of the VCAP pin, and what capacitor value is required?
The VCAP pin supplies hold-up energy for the AutoStore operation during VCC dropout. A 4.7 µF tantalum capacitor (±20%, 10 V rating) is specified in the datasheet and must be placed within 10 mm of the pin with low-inductance routing. Ceramic capacitors are not recommended due to insufficient charge capacity and voltage coefficient drift under bias.
Does CY14E116L-ZS25XIT support Sleep mode via the ZZ pin?
No. Sleep mode (activated by pulling ZZ LOW) is only available in the 165-ball FBGA package variants. In the 44-pin TSOP II package (ZS25XIT), the ZZ pin is marked as NC (No Connect) and has no internal connection - it must be left unconnected or tied to VCC/VSS per PCB routing convenience.
How does hardware STORE differ from software STORE in terms of timing and reliability?
Hardware STORE triggered by external HSB LOW begins within 100 ns of assertion and completes in ≤20 ms (tSTH), independent of CPU activity. Software STORE requires precise address/data sequences and takes ~25 ms (tSW), making it vulnerable to interrupt latency or reset during execution. Hardware STORE is preferred for fail-safe contexts.
Can CY14E116L-ZS25XIT be used in a ×16 or ×32 configuration?
No. The "-L" suffix denotes ×8 organization (2048K × 8). The "-N" suffix is for ×16 (1024K × 16), and "-S" for ×32 (512K × 32). Pinouts, address/data bus widths, and byte-enable signals differ fundamentally - mixing configurations causes functional failure and is not supported.
