Product details
Overview
CY14B116N-ZSP45XIT from Infineon Technologies (formerly Cypress) is a 16-Mbit nonvolatile SRAM (nvSRAM) with ×16 organization (1024K × 16), 45-ns access time, 2.7–3.6 V supply, and QuantumTrap nonvolatile storage. It performs automatic STORE on power-down using an external capacitor (VCAP), supports software/hardware-controlled STORE/RECALL, and operates across –40 °C to +85 °C for industrial data logging systems.
For engineers reviewing the CY14B116N-ZSP45XIT datasheet, CY14B116N-ZSP45XIT pinout, CY14B116N-ZSP45XIT application, or CY14B116N-ZSP45XIT equivalent, key selection criteria include ×16 bus interface compatibility, AutoStore timing under brown-out conditions, HSB signal behavior during STORE, and TSOP II package footprint alignment with legacy PCB layouts.
Technical Context
This nvSRAM integrates a fast 45-ns SRAM array with embedded QuantumTrap nonvolatile elements per cell, enabling infinite SRAM read/write cycles and 1 million STORE endurance. STORE transfers data from volatile SRAM to nonvolatile storage either automatically at power loss (via VCAP discharge), via hardware trigger (HSB pin assertion), or via software command.
RECALL restores data from QuantumTrap to SRAM on power-up or via software, ensuring zero-latency memory recovery. The device uses dual CE logic in TSOP II configuration (CE = CE1 AND NOT CE2), supports byte enables (BHE/BLE), and enters ultra-low-power Sleep mode (10 µA) when ZZ is asserted - though Sleep is not supported in this TSOP II variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1024K × 16 organization), directly supporting 16-bit microcontroller/data bus interfaces without glue logic. |
| Access Time | 45 ns - defines maximum clock rate for synchronous read/write cycles in high-speed control applications. |
| Supply Voltage | 2.7 V to 3.6 V - compatible with 3.3 V industrial systems and tolerant of rail droop during transient events. |
| Data Retention | 20 years at +85 °C - guarantees long-term data integrity in unpowered storage without battery backup. |
| STORE Endurance | 1 million cycles - supports frequent power-cycle logging in energy-metering or event-recorder deployments. |
| Active Current | 75 mA at 45 ns - determines thermal budget and regulator sizing for continuous operation. |
| Standby Current | 650 µA - enables low-power monitoring modes between data capture intervals. |
Pinout & Package
Package: 54-pin Thin Small-Outline Package (TSOP II), 1.0 mm body height, standard JEDEC MO-141AC footprint. Pin 1 index corner marked; lead finish is matte tin.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 1024K-word addressing space; A0–A19 fully decoded for ×16 mode - no address multiplexing required. |
| DQ0–DQ15 | Bidirectional Data I/O | 16-bit parallel data path; tristated when OE HIGH or CE HIGH - matches standard SRAM bus timing. |
| CE | Chip Enable | Single active-low enable (TSOP II); asserts internal logic only when LOW - simplifies address decoding. |
| WE | Write Enable | Active-low write strobe; latches DQ inputs on falling edge - aligns with asynchronous microprocessor write protocols. |
| OE | Output Enable | Active-low output gate; controls DQ drivers independently of CE - enables shared-bus contention management. |
| HSB | Hardware STORE Busy | Open-drain status output; driven LOW during STORE execution - provides hardware handshake for system-level power sequencing. |
| VCAP | AutoStore Capacitor Terminal | Connects external 4.7 µF tantalum capacitor; supplies hold-up energy for reliable STORE during VCC collapse. |
| BHE / BLE | Byte Enable Inputs | Active-low enables for upper/lower 8 bits - allows 8-bit accesses on 16-bit bus without data corruption. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar nvSRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STK14C88-45I5F | 45 ns, ×16, 3.3 V, but uses older SONOS nonvolatile technology with 100k STORE cycles and 10-year retention. | Limited to less demanding industrial environments due to lower endurance and retention specs. | Select when cost sensitivity outweighs long-term data integrity requirements. |
| FM16W08-45-TG | 45 ns, ×16, 3.3 V, integrated capacitor - eliminates external VCAP but increases package size and limits thermal derating. | Suitable for space-constrained designs where board area > capacitor sourcing complexity. | Prefer when VCAP placement is impractical and thermal margin exceeds 15 °C above ambient. |
Compared with STK14C88-45I5F and FM16W08-45-TG, CY14B116N-ZSP45XIT delivers superior 20-year retention and 1M STORE cycles while maintaining identical ×16 timing and pinout - making it the optimal upgrade path for reliability-critical field deployments.

FAQ
What is the function of the VCAP pin, and what capacitor value is required?
The VCAP pin connects to an external 4.7 µF tantalum capacitor that supplies hold-up energy during VCC collapse, enabling reliable AutoStore execution. A minimum capacitance of 4.7 µF with ≤100 mΩ ESR is specified; deviation risks incomplete STORE under fast power-down transients. Ceramic capacitors are not recommended due to insufficient charge capacity and voltage coefficient effects.
How does the HSB pin behave during a STORE operation?
HSB is an open-drain output that goes LOW at STORE initiation and remains LOW until STORE completion (tSTORE max = 20 ms). After completion, it is actively driven HIGH for tHHHD (100 ns min), then held HIGH by a weak internal pull-up. An external 4.7 kΩ pull-up is recommended for noise immunity in noisy industrial environments.
Can CY14B116N-ZSP45XIT be used in place of a standard SRAM without firmware changes?
No - while read/write timing matches standard ×16 SRAMs, firmware must explicitly manage STORE/RECALL sequences and monitor HSB. Direct replacement requires disabling AutoStore, adding software RECALL at startup, and verifying byte-enable (BHE/BLE) handling - otherwise data loss or bus contention may occur.
Is the 54-pin TSOP II package RoHS compliant and lead-free?
Yes - CY14B116N-ZSP45XIT uses matte tin lead finish and complies with EU RoHS Directive 2011/65/EU and China RoHS GB/T 26572-2011. The package contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE, and is rated for peak reflow temperatures up to 260 °C per JEDEC J-STD-020.
