Product details
Overview
CY14B116N-Z30XIT from Infineon Technologies (formerly Cypress) is a 16-Mbit nonvolatile SRAM organized as 1024K × 16, featuring QuantumTrap nonvolatile storage, 30-ns access time, and AutoStore on power-down. It operates from 2.7 V to 3.6 V across –40 °C to +85 °C and is used in industrial control systems requiring instant data retention during unexpected power loss.
For engineers reviewing the CY14B116N-Z30XIT datasheet, CY14B116N-Z30XIT pinout, CY14B116N-Z30XIT application, or CY14B116N-Z30XIT equivalent, key selection criteria include ×16 bus width support, HSB-driven hardware STORE capability, VCAP-supervised nonvolatile write integrity, and TSOP II package compatibility with legacy memory controllers.
Technical Context
This nvSRAM integrates a parallel SRAM array (1024K × 16) with embedded QuantumTrap nonvolatile elements per cell, enabling infinite SRAM read/write cycles and 1 million STORE cycles. The device supports three STORE initiation methods: AutoStore (power-down), hardware-triggered via HSB pin, and software-controlled via command sequence.
It features dual CE inputs in TSOP I and FBGA packages (logically combined as single CE for timing), byte enable pins (BLE/BHE) for ×16 operation, and Sleep mode (ZZ pin) - though ZZ is only functional in the 165-ball FBGA variant, not in the Z30XIT's 54-pin TSOP II package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1024K × 16 organization), directly supporting 16-bit microcontroller/microprocessor data buses without glue logic. |
| Access Time | 30 ns - guarantees sub-33 MHz synchronous interface timing for real-time deterministic memory access in PLCs and motion controllers. |
| Supply Voltage | 2.7 V to 3.6 V - compatible with modern low-voltage industrial I/O rails and eliminates need for level-shifting in 3.3 V systems. |
| Data Retention | 20 years at +85 °C - ensures long-term firmware/state persistence in sealed enclosures without battery backup. |
| STORE Endurance | 1 million STORE cycles to QuantumTrap - supports frequent power-cycle logging in energy metering and edge telemetry applications. |
| Active Current | 75 mA at 45 ns (typical), scaled proportionally at 30 ns - enables thermal budgeting for dense memory subsystems in compact industrial modules. |
| Operating Temp | –40 °C to +85 °C - validated for deployment in uncontrolled factory-floor environments and outdoor utility cabinets. |
Pinout & Package
The CY14B116N-Z30XIT is housed in a 54-pin Thin Small-Outline Package (TSOP II), 0.8 mm pitch, with 22 mm × 10 mm footprint and standard JEDEC MO-141AC mechanical outline. Pin 1 is marked by a beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Input | 1024K-word addressing space; A0–A19 fully decoded for direct connection to 16-bit CPU address bus (no address multiplexing required). |
| DQ0–DQ15 | Bidirectional Data I/O | Full 16-bit parallel data path; supports burst reads/writes and byte-level writes using BLE/BHE controls. |
| CE | Chip Enable | Single active-low chip select (TSOP II configuration); enables memory access only when asserted, reducing bus contention in multi-chip systems. |
| WE | Write Enable | Active-low write strobe synchronized with CE and OE; defines write cycle timing window per JEDEC standard. |
| OE | Output Enable | Active-low control of output buffers; allows shared data bus operation with other peripherals without external tri-state logic. |
| HSB | Hardware STORE Busy | Open-drain status signal: LOW during STORE execution; can be externally pulled LOW to initiate nonvolatile store independent of software state. |
| VCAP | AutoStore Capacitor Terminal | Connects to external 4.7 µF–10 µF tantalum capacitor; supplies hold-up energy for reliable STORE completion during <100 µs power collapse. |
| VCC / VSS | Power / Ground | Dual VCC (pins 27, 40) and multiple VSS (pins 1, 26, 41, 54) reduce IR drop and improve noise immunity in high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| QuantumTrap Nonvolatile Storage | Embedded per-cell nonvolatile element enables zero-latency RECALL on power-up and eliminates external EEPROM/NVRAM chips and associated firmware overhead. |
| Hands-off AutoStore | Automatic STORE triggered solely by VCC decay below threshold - requires no host intervention or system-level power-fail detection circuitry. |
| Hardware STORE via HSB | External pull-down of HSB initiates immediate nonvolatile store, enabling deterministic crash recovery in safety-critical motion control loops. |
| Software STORE/RECALL Control | Register-based command interface allows selective STORE/RECALL of critical memory regions (e.g., configuration registers only), minimizing wear on nonvolatile elements. |
| Low-Power Standby Mode | 650 µA standby current enables always-on logging in battery-backed edge nodes without compromising runtime between charges. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar nonvolatile SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STK14C88-3A55I | 55 ns access time; 3.3 V only; uses NVSRAM with older SONOS technology; no HSB pin; requires external power-fail monitor for STORE. | Limited to slower control loops; lacks hardware-triggered STORE; higher STORE latency increases risk of incomplete writes during fast transients. | Select only if 55 ns timing suffices and system already includes dedicated power-fail detection circuitry. |
| FM16W08-30-TG | 30 ns access; 2.7–3.6 V; integrated power management; but uses FRAM (not nvSRAM); unlimited STORE endurance; no VCAP capacitor required. | Eliminates external capacitor but exhibits higher write latency variability and lower radiation tolerance than QuantumTrap nvSRAM. | Prefer for ultra-high-write-cycle applications where capacitor placement is constrained, but verify gamma/EMI resilience for rail or medical use. |
Compared with STK14C88-3A55I and FM16W08-30-TG, CY14B116N-Z30XIT uniquely delivers deterministic 30 ns timing, hardware-initiated STORE via HSB, and proven 20-year data retention in harsh thermal environments - making it optimal for safety-critical industrial and transportation systems.

FAQ
What is the function of the VCAP pin, and what capacitor value is required?
The VCAP pin supplies hold-up energy for AutoStore during power loss. A 4.7 µF to 10 µF low-ESR tantalum capacitor must be connected between VCAP and VSS, placed within 5 mm of the package. This capacitor sustains internal circuitry for ≥100 µs to complete STORE, and its value directly determines minimum VCC dropout duration supported.
Does CY14B116N-Z30XIT support Sleep mode, and how is it enabled?
No - Sleep mode (via ZZ pin) is not supported in the 54-pin TSOP II package of CY14B116N-Z30XIT. The ZZ pin is reserved and must be tied HIGH or left unconnected. Sleep mode is only implemented in the 165-ball FBGA variant per datasheet Figure 6 and Pin Definition table footnote.
How does hardware STORE differ from AutoStore in terms of timing and reliability?
Hardware STORE (triggered by pulling HSB LOW) begins immediately and completes in ≤15 µs, independent of VCC slope. AutoStore activates only after VCC drops below ~2.0 V and relies on VCAP discharge profile. Hardware STORE thus provides higher reliability during slow brownouts or partial power faults where AutoStore may not trigger.
Can CY14B116N-Z30XIT replace standard SRAMs without design changes?
Yes - it is pin-compatible and electrically compatible with standard 1024K × 16 SRAMs (e.g., AS6C1008), requiring only addition of VCAP capacitor and optional HSB pull-up. No changes to address/data bus routing, timing logic, or firmware are needed unless leveraging STORE/RECALL features.
