Product details
Overview
CY14B116L-Z45XI from Infineon Technologies (formerly Cypress) is a 16-Mbit nonvolatile SRAM (nvSRAM) with QuantumTrap technology, organized as 2048K × 8, supporting 45-ns access time, 2.7–3.6 V operation, and industrial temperature range (–40 °C to +85 °C). It enables hands-off STORE on power-down using only an external capacitor and supports software/hardware-triggered STORE/RECALL in embedded systems requiring persistent memory without battery backup.
For engineers reviewing the CY14B116L-Z45XI datasheet, CY14B116L-Z45XI pinout, CY14B116L-Z45XI application, or CY14B116L-Z45XI equivalent, key selection considerations include its 44-pin TSOP II package, AutoStore timing under voltage droop, SRAM-to-QuantumTrap STORE endurance (1 million cycles), and compatibility with legacy Cypress nvSRAM designs in metering, networking, and industrial control.
Technical Context
This nvSRAM integrates volatile SRAM and nonvolatile QuantumTrap storage in each cell, enabling atomic STORE/RECALL without external controllers. Its dual-mode operation-standard SRAM read/write plus deterministic nonvolatile backup-eliminates write latency penalties during power loss and avoids EEPROM-like wear-out limitations.
The device uses internal voltage monitoring to trigger AutoStore when VCC drops below threshold, backed by VCAP-supplied energy. Pin-controlled HSB provides hardware handshake for STORE completion, while ZZ enables Sleep mode (in FBGA variants) - though CY14B116L-Z45XI's 44-pin TSOP II does not support ZZ-based sleep.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar nvSRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY14B116L-Z35XI | 35-ns access time; identical 44-pin TSOP II package and pinout | Suitable where system timing margin allows slower access; reduces power slightly due to lower drive strength | Select when 35 ns meets bus timing budget and lower active current (65 mA) is prioritized over peak speed |
| FM16W08-45-TG | F-RAM-based 8-Mbit device (not nvSRAM); 45 ns access; SOIC-28 package | Limited density (half capacity); no STORE/RECALL latency; unlimited endurance but shorter data retention (10 years) | Choose only if application requires ultra-high write endurance (>10¹⁴ cycles) and can accept reduced density and retention |
Compared with CY14B116L-Z35XI and FM16W08-45-TG, the CY14B116L-Z45XI uniquely delivers 16-Mbit density with 45-ns SRAM performance, 20-year retention, and seamless AutoStore-making it optimal for next-generation smart infrastructure where capacity, speed, and long-term reliability are jointly critical.

FAQ
What is the minimum VCAP capacitance required for reliable AutoStore on CY14B116L-Z45XI?
The datasheet specifies a minimum 4.7 µF tantalum capacitor on VCAP, rated ≥6.3 V, with ESR ≤5 Ω. This value ensures sufficient energy to complete STORE before VCC falls below the retention threshold (≈2.0 V). Ceramic capacitors are not recommended due to insufficient charge capacity and voltage coefficient effects.
Does CY14B116L-Z45XI support byte-level STORE operations?
No. STORE always transfers the entire SRAM array (16 Mbit) to QuantumTrap elements. There is no partial or byte-selective STORE function-the operation is atomic and full-array, triggered by power loss, software command, or HSB assertion.
Can CY14B116L-Z45XI be used in place of standard SRAM without modifying PCB layout?
Yes, for pin-compatible replacements like CY14B116L-Z35XI or CY14B116L-Z25XI-same 44-pin TSOP II footprint and signal mapping. However, VCAP addition and decoupling adjustments are mandatory; omitting VCAP disables AutoStore and risks data loss on power loss.
Is the HSB pin strictly an output, or can it be driven externally?
HSB is bidirectional: it outputs LOW during active STORE and accepts external LOW assertion to initiate STORE. When used as input, it must be pulled LOW for ≥100 ns to trigger hardware STORE; the internal weak pull-up returns it HIGH post-operation unless actively held.
