Product details
Overview
CY14E116N-Z30XIT from Infineon Technologies (formerly Cypress) is a 16-Mbit nonvolatile SRAM organized as 1024K × 16, operating at 5 V with 30-ns access time. It integrates QuantumTrap nonvolatile storage per cell, enabling automatic STORE on power-down and software/hardware-controlled RECALL. Used in industrial control systems requiring persistent memory without battery backup.
For engineers reviewing the CY14E116N-Z30XIT datasheet, CY14E116N-Z30XIT pinout, CY14E116N-Z30XIT application, or CY14E116N-Z30XIT equivalent, key selection criteria include 5 V operation, ×16 bus interface, TSOP II packaging, AutoStore timing, and HSB signaling for STORE status monitoring.
Technical Context
This nvSRAM combines a high-speed 30-ns SRAM array with embedded QuantumTrap nonvolatile elements-each memory cell retains data independently. STORE transfers data from SRAM to nonvolatile storage either automatically at VCC dropout (with external VCAP capacitor), via HSB pin assertion, or through software command.
RECALL restores data from QuantumTrap to SRAM on power-up or via software; both operations are atomic and non-disruptive to ongoing reads. The device supports dual CE in TSOP I and FBGA packages but CY14E116N-Z30XIT uses single CE in 54-pin TSOP II package with dedicated BHE/ BLE byte enables for ×16 mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16 Mbit (1024K × 16) - provides 2 MB of directly addressable, byte-accessible nonvolatile memory space. |
| Access Time | 30 ns - guarantees sub-30-ns read/write latency under 5 V, 25 °C conditions for deterministic real-time system timing. |
| VCC Range | 4.5 V to 5.5 V - compatible with legacy 5 V logic systems and tolerant of ±10 % supply variation without regulation. |
| Data Retention | 20 years - ensures long-term data integrity in unpowered storage without refresh or external power sources. |
| STORE Endurance | 1 million cycles - supports frequent power-cycle logging in industrial PLCs or metering applications. |
| Operating Temp | –40 °C to +85 °C - qualified for extended temperature operation in factory automation and outdoor infrastructure. |
| Standby Current | 650 µA - enables low-power hold state during system sleep without compromising STORE readiness. |
Pinout & Package
Package: 54-pin Thin Small-Outline Package (TSOP II), 0.8 mm pitch, 20.0 mm × 10.0 mm body size, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Input | 1024K-word addressing for ×16 configuration; A0 selects LSB of 16-bit word, A19 selects MSB. |
| DQ0–DQ15 | Bidirectional Data I/O | Full 16-bit parallel data bus; tristates when OE HIGH or CE HIGH to prevent bus contention. |
| CE | Chip Enable | Single active-low chip select; enables internal logic and memory access only when LOW (TSOP II variant). |
| WE | Write Enable | Active-low write strobe; latches DQ0–DQ15 into SRAM on falling edge while CE and OE are asserted. |
| OE | Output Enable | Active-low output gate; controls DQ drivers during read; must be LOW for valid data output. |
| BHE, BLE | Byte Enable | BHE enables upper byte (DQ15–DQ8), BLE enables lower byte (DQ7–DQ0); supports 8-bit subsystem interfacing. |
| HSB | Hardware STORE Busy | Open-drain status signal: LOW during STORE execution; can initiate STORE when externally pulled LOW. |
| VCAP | AutoStore Capacitor Terminal | Connects to 4.7 µF tantalum capacitor; supplies energy for STORE during VCC collapse (tSTORE ≤ 20 ms). |
Key Features
| Feature | Design Value |
|---|---|
| QuantumTrap Nonvolatile Storage | Embedded per-cell nonvolatile element enables infinite SRAM read/write cycles without wearing out NV storage. |
| Hands-off AutoStore | Zero-software intervention STORE triggered by VCC drop below threshold, using only external VCAP capacitor. |
| Hardware STORE Initiation | HSB pin doubles as input: pulling it LOW initiates immediate STORE independent of power rail behavior. |
| Software-Controlled STORE/RECALL | Two-byte command sequence over SRAM interface allows precise timing control of nonvolatile operations. |
| Sleep Mode Support | Not available on this TSOP II variant - Sleep mode is exclusive to 165-ball FBGA package per datasheet. |
Applications
| Industrial PLC Data Logging | Point-of-Sale Transaction Buffer |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar nonvolatile SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY14E116N-Z25XIT | 25-ns access time, same 5 V VCC range and 1024K × 16 organization. | Requires tighter timing margins in high-speed bus interfaces; higher active current (85 mA vs. 75 mA). | Select when system clock domain demands sub-25-ns setup/hold timing for burst writes. |
| CY14B116N-Z30XI | 3.3 V operation (2.7–3.6 V), identical 30-ns speed and ×16 configuration. | Designed for modern low-voltage microcontrollers; incompatible with 5 V bus signaling without level translation. | Choose for new designs targeting 3.3 V domains where power efficiency and compatibility with ARM Cortex-M MCUs are prioritized. |
Compared with CY14E116N-Z25XIT and CY14B116N-Z30XI, the CY14E116N-Z30XIT balances 5 V legacy compatibility, moderate 30-ns latency, and optimized 75 mA active current-making it ideal for cost-sensitive industrial retrofits where voltage margin and timing slack are constrained.

FAQ
What is the required VCAP capacitor value and type for reliable AutoStore operation?
A 4.7 µF solid tantalum capacitor rated for ≥6.3 V must be placed between VCAP and VSS, within 10 mm of the package. This value ensures sufficient energy for full 16-Mbit STORE within 20 ms after VCC drops below 3.0 V. Ceramic capacitors are not recommended due to insufficient capacitance retention under bias.
Can CY14E116N-Z30XIT operate in Sleep mode?
No. Sleep mode (activated via ZZ pin) is only supported in the 165-ball FBGA package variant per datasheet Section 7. The CY14E116N-Z30XIT uses a 54-pin TSOP II package, which lacks the ZZ pin and associated internal circuitry required for Sleep mode entry and wake-up sequencing.
How does the HSB pin function during a STORE operation?
HSB is an open-drain output that goes LOW at STORE initiation and remains LOW until STORE completes (typically ≤20 ms). When used as input, pulling HSB LOW externally triggers immediate STORE regardless of VCC level. After completion, HSB is driven HIGH for tHHHD (100 ns min) then held HIGH by weak internal pull-up.
Is byte-level STORE possible with CY14E116N-Z30XIT?
No. STORE always operates on the entire 16-Mbit array-there is no partial or byte-selective STORE capability. However, BHE/ BLE pins allow selective 8-bit reads/writes to upper/lower bytes during normal SRAM operation, preserving data integrity in mixed-width subsystems.
