Product details
Overview
CY14B104NA-ZS25XI from Cypress Semiconductor is a 4-Mbit non-volatile SRAM (nvSRAM) organized as 256K × 16, operating at 3 V ±10%, with 25 ns access time, AutoStore on power-down, and QuantumTrap non-volatile storage. It serves as drop-in SRAM replacement in industrial control systems requiring persistent data retention without external backup power or batteries.
For engineers reviewing the CY14B104NA-ZS25XI datasheet, CY14B104NA-ZS25XI pinout, CY14B104NA-ZS25XI application, or CY14B104NA-ZS25XI equivalent, key selection criteria include ×16 bus interface support, HSB-controlled hardware STORE capability, VCAP-based autonomous power-loss protection, and 1 million STORE endurance with 20-year data retention.
Technical Context
This nvSRAM integrates standard SRAM array logic with parallel QuantumTrap non-volatile cells per bit, enabling simultaneous STORE/RECALL across all 256K words. The architecture supports three STORE triggers: AutoStore (VCC dropout), hardware STORE (HSB assertion), and software STORE (address sequence).
It operates exclusively in ×16 mode for this variant, using A0–A17 address lines and DQ0–DQ15 bidirectional data lines, with BHE/ BLE byte enables. HSB functions both as input (STORE request) and open-drain output (busy indicator), while VCAP supplies regulated energy for reliable STORE execution during brownout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 4 Mbit (256K × 16 organization) |
| Access Time | 25 ns - guarantees read data valid within 25 ns after address/control setup |
| Supply Voltage | 3.0 V ±10% - single-rail operation compatible with 3.3 V system rails with margin |
| STORE Endurance | 1 million cycles - defines maximum number of non-volatile write operations before wear-out |
| Data Retention | 20 years at +85°C - guaranteed non-volatile data hold without refresh or power |
| Operating Temperature | –40°C to +85°C - qualified for industrial ambient environments |
| AutoStore Trigger | VCC < VSWITCH - automatic initiation when main supply drops below switch threshold |
Pinout & Package
Package: 48-ball fine-pitch ball grid array (FBGA), RoHS-compliant, 6 mm × 8 mm footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Input | 18-bit address bus for 256K-word addressing; no A18 required in ×16 mode |
| DQ0–DQ15 | I/O | 16-bit bidirectional data bus; full-width interface eliminates byte-lane multiplexing |
| WE, CE, OE | Input | Standard SRAM control trio: write enable (active low), chip enable (active low), output enable (active low) |
| BHE, BLE | Input | Byte enable controls for upper/lower 8 bits of DQ bus; required for partial-word writes |
| HSB | I/O | Hardware STORE Busy: input to initiate STORE, open-drain output indicating active STORE cycle |
| VCAP | Power | Capacitor connection point; internal regulator charges external 0.1 µF capacitor for STORE energy reserve |
| VCC, VSS | Power | Single 3 V supply and ground; decoupling required per high-speed SRAM layout practice |
Key Features
| Feature | Design Value |
|---|---|
| QuantumTrap Non-Volatile Cell | Embedded per-bit NV element enabling infinite SRAM reads/writes alongside 1M STORE cycles |
| AutoStore on Power Loss | Self-triggered STORE using VCAP-supplied energy when VCC falls below VSWITCH, no host intervention needed |
| Hardware STORE Control | HSB pin allows deterministic, externally timed STORE initiation with busy feedback for synchronization |
| Software STORE/RECALL | Address-sequence commands enable STORE/RECALL without pin toggling-ideal for firmware-controlled persistence |
| Industrial Temp Range | –40°C to +85°C operation validated across voltage and timing margins per JEDEC JESD22-A108 |
Applications
| Industrial PLC Data Logging | Medical Device Configuration Storage |
|---|---|
|

| Telecom Base Station Control Memory | Avionics Black Box Recorder Buffer |
|
Use Scenario: Caching critical configuration parameters and fault logs in LTE/5G remote radio units exposed to wide thermal swings. IC Role / Device Role / Timing Role: Industrial-grade nvSRAM interfacing with FPGA or ARM-based baseband processor via ×16 bus. Use Value: Provides deterministic STORE latency (<10 ms) and immunity to voltage droop during RF burst transmission. |
Use Scenario: Capturing flight sensor snapshots in crash-protected recorders where power interruption is abrupt and unannounced. IC Role / Device Role / Timing Role: High-reliability memory with AutoStore triggered by VCC collapse, independent of host CPU response time. Use Value: Ensures final pre-failure data is preserved even if system reset occurs mid-capture due to impact-induced brownout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar non-volatile SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STK14C88-3AJ | 3 V, 256K × 16 nvSRAM; uses SONOS non-volatile technology; 70 ns access; no HSB pin | Lacks hardware STORE trigger and busy signaling; relies solely on software STORE or power-loss detection | Select when HSB synchronization is unnecessary and slower access time is acceptable |
| FM24V10-G | 4-Mbit F-RAM (256K × 16); 3 V; 55 ns access; unlimited endurance; no STORE latency or VCAP capacitor | No STORE/RECALL latency or energy dependency; inherently non-volatile but lower speed than nvSRAM | Select when infinite write endurance outweighs 25 ns SRAM performance and deterministic STORE timing |
Compared with STK14C88-3AJ and FM24V10-G, CY14B104NA-ZS25XI uniquely delivers 25 ns SRAM speed with hardware-synchronized STORE via HSB and VCAP-backed power-loss resilience-critical for time-sensitive industrial logging where latency and reliability must coexist.

FAQ
What is the function of the VCAP pin?
The VCAP pin connects to an external 0.1 µF capacitor that stores charge during normal operation. When VCC drops below VSWITCH, the internal regulator isolates VCAP and supplies energy to complete a full STORE operation-ensuring data integrity during uncontrolled power loss without host intervention.
Does CY14B104NA-ZS25XI support ×8 operation?
No. CY14B104NA is strictly a 256K × 16 device using A0–A17 and DQ0–DQ15. The ×8 variant is CY14B104LA (512K × 8). Pinout, address depth, and data bus width are fixed per part number; mixing configurations is not supported.
How does the HSB pin behave during STORE?
HSB is driven LOW by the device during any STORE (AutoStore, hardware, or software) to signal busy status. After completion, it is actively driven HIGH for tHHHD (≤100 ns), then held HIGH by an internal 100 kΩ pull-up. External pull-up is optional but recommended for noise immunity.
Can AutoStore be disabled?
Yes-via a specific software sequence documented in the datasheet (page 8, "Preventing AutoStore"). Disabling is required if no VCAP capacitor is installed, as attempted AutoStore without sufficient charge corrupts stored data. Once disabled, STORE requires explicit hardware or software initiation.
