Product details
Overview
CY14B108N-ZSP25XIT from Cypress Semiconductor is an 8-Mbit nonvolatile SRAM (nvSRAM) with 512 K × 16 organization, single 3 V (+20%, –10%) supply operation, 25 ns access time, and QuantumTrap nonvolatile storage technology. It performs automatic STORE on power-down using a VCAP capacitor, supports software- and hardware-initiated STORE/RECALL, and guarantees 20-year data retention and 1 million STORE cycles. It is used in industrial control systems requiring persistent memory without battery backup.
For engineers reviewing the CY14B108N-ZSP25XIT datasheet, CY14B108N-ZSP25XIT pinout, CY14B108N-ZSP25XIT application, or CY14B108N-ZSP25XIT equivalent, key selection criteria include ×16 bus interface support, HSB-controlled hardware STORE timing, VCAP-based AutoStore reliability, and industrial temperature range compliance (–40°C to +85°C).
Technical Context
The CY14B108N-ZSP25XIT integrates standard SRAM and QuantumTrap nonvolatile elements in each cell, enabling parallel STORE/RECALL across all 524,288 words. Its architecture decouples volatile read/write (infinite cycles) from nonvolatile STORE (1M cycles), with automatic power-loss detection via VCC monitoring and VCAP discharge control.
STORE is triggered by falling VCC below VSWITCH (2.7 V), initiating capacitor-powered transfer from SRAM to QuantumTrap cells; RECALL occurs on power-up when VCC exceeds VSWITCH, restoring data in tHRECALL ≤ 20 ms. The HSB pin serves dual role: open-drain busy indicator during STORE and hardware trigger input with tDELAY = 100 ns minimum setup.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 8 Mbit organized as 512 K × 16 - supports 16-bit microprocessor/data bus interfaces without external byte multiplexing. |
| Access Time | 25 ns - enables direct interfacing with legacy 40 MHz bus systems (e.g., Intel 80C188, Motorola 68K) without wait states. |
| Supply Voltage | 3.0 V ±10% (2.7–3.6 V) - compatible with single-supply industrial 3.3 V rails; no separate VIO required. |
| Data Retention | 20 years at +85°C - validated for long-term unpowered storage in remote telemetry and energy metering applications. |
| STORE Endurance | 1 million cycles - sufficient for daily firmware logging in programmable logic controllers (PLCs) over 27+ years. |
| Operating Temperature | –40°C to +85°C - qualified for use in industrial automation enclosures without forced cooling. |
| VCAP Requirement | 0.1 µF ceramic capacitor - provides ~2.5 ms STORE hold time at VCC = 2.7 V; eliminates need for backup batteries or supercaps. |
Pinout & Package
Package: 48-ball fine-pitch ball grid array (FBGA), 6 mm × 8 mm, 0.8 mm pitch, RoHS-compliant, industrial-grade thermal profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Input | 19-bit address bus for 512 K-word addressing; A18 is MSB in ×16 mode; no A19 used. |
| DQ0–DQ15 | Bidirectional Data I/O | 16-bit parallel data path; supports burst writes and full-word transfers without byte enable arbitration. |
| WE, CE, OE | Control Inputs | Active-low write enable, chip enable, output enable - standard SRAM timing interface compatible with ASIC/FPGA glue logic. |
| BHE, BLE | Byte Enable Inputs | Enable upper/lower 8 bits independently; required for partial-word writes in ×16 configuration. |
| HSB | Hardware STORE Busy | Open-drain status output (LOW = STORE active); also accepts external LOW pulse to initiate hardware STORE. |
| VCAP | AutoStore Capacitor Terminal | Internal regulator charges external 0.1 µF cap; supplies energy for STORE during VCC collapse - no external charge pump needed. |
Key Features
| Feature | Design Value |
|---|---|
| QuantumTrap Nonvolatile Storage | Embedded per-cell nonvolatile element enables true nvSRAM behavior - no external EEPROM or flash required for state retention. |
| AutoStore on Power Loss | VCC monitoring circuit triggers STORE automatically when voltage drops below 2.7 V, using only VCAP capacitor - zero firmware overhead. |
| Software STORE/RECALL | Configurable via address-based command sequence (no special protocol IC or SPI interface needed) - integrates into existing memory-mapped drivers. |
| Hardware STORE Trigger | HSB pin accepts external LOW pulse to force immediate STORE - enables deterministic save-on-event (e.g., emergency stop, fault capture). |
| Industrial Temperature Range | –40°C to +85°C operation with full timing spec compliance - suitable for DIN-rail mounted PLCs and motor drives. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar nvSRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STK14C88-3LF35I | 512 K × 16, 35 ns access, 3.3 V ±10%, uses BBSRAM architecture with internal lithium battery | Requires battery replacement every 10 years; not RoHS-compliant due to Li coin cell | Select only if legacy design mandates pin-compatible upgrade with minimal layout change and battery service acceptable. |
| FM24V10-G | 1 Mbit F-RAM, 40 MHz SPI interface, 2.7–3.6 V, unlimited endurance, but serial interface adds latency and MCU overhead | No parallel bus support; requires driver rewrite and interrupt handling for STORE/RECALL coordination | Choose for low-power, high-write-cycle applications where parallel interface is unnecessary and SPI bandwidth suffices. |
Compared with STK14C88-3LF35I and FM24V10-G, CY14B108N-ZSP25XIT delivers deterministic 25 ns parallel access, zero-battery reliability, and hardware-triggered STORE - making it optimal for real-time industrial systems where timing predictability and maintenance-free operation are mandatory.

FAQ
What is the function of the VCAP pin, and what capacitor value is required?
The VCAP pin connects to an external 0.1 µF ceramic capacitor that supplies energy for the AutoStore operation during VCC collapse. Cypress specifies this value to ensure ≥2.5 ms STORE hold time at VCC = 2.7 V. Using a smaller capacitor risks incomplete STORE and data corruption; larger values do not improve performance and may delay power-up RECALL timing.
Can CY14B108N-ZSP25XIT operate in ×8 mode?
No. CY14B108N is factory-configured for 512 K × 16 organization only. The "N" suffix denotes ×16 data width; the "L" variant (CY14B108L) is the ×8 version. Pinout, address mapping (A0–A18), and DQ0–DQ15 usage are fixed for 16-bit operation - no mode-select pins or software configuration exist.
How does the HSB pin behave during a STORE operation?
HSB is driven LOW by the device during any STORE (AutoStore, Hardware, or Software) to indicate busy status. After completion, it is actively driven HIGH for tHHHD (≤100 ns), then held HIGH by an internal 100 kΩ pull-up. If externally pulled LOW, it initiates a hardware STORE after tDELAY (100 ns min), provided at least one write occurred since last STORE/RECALL.
Is the AutoStore Disable feature functional in this device?
No. The datasheet errata (page 24) explicitly states the AutoStore Disable feature does not work in CY14B108L/N devices. If VCAP is unconnected, AutoStore cannot be disabled via software - attempting AutoStore without capacitor causes data corruption. The only safe workaround is connecting the specified 0.1 µF capacitor.
