Product details
Overview
CY14B108N-ZSP25XI from Cypress Semiconductor is an 8-Mbit nonvolatile SRAM (nvSRAM) organized as 512 K × 16, operating at 25 ns access time with single 3 V (+20%, –10%) supply, industrial temperature range (–40°C to +85°C), and QuantumTrap nonvolatile storage technology. It performs automatic STORE on power-down using VCAP capacitor, supports software/hardware STORE/RECALL, and delivers 20-year data retention with 1 million STORE cycles.
For engineers reviewing the CY14B108N-ZSP25XI datasheet, CY14B108N-ZSP25XI pinout, CY14B108N-ZSP25XI application, or CY14B108N-ZSP25XI equivalent, key selection criteria include ×16 bus interface support, HSB-controlled hardware STORE timing, VCAP capacitor sizing (0.1 µF), AutoStore enable/disable behavior, and BHE/BLE byte-enable compatibility with 16-bit microprocessor buses.
Technical Context
The CY14B108N-ZSP25XI integrates standard SRAM array (2048 × 2048 × 2) with parallel QuantumTrap nonvolatile elements per cell, enabling simultaneous STORE/RECALL across all memory locations. Its architecture decouples volatile read/write (infinite cycles) from nonvolatile STORE endurance (1M cycles) and retention (20 years).
STORE is triggered by power loss (via VCAP discharge below VSWITCH), external HSB assertion, or software address sequence; RECALL occurs automatically on power-up or via software command. The device inhibits SRAM access during STORE/RECALL and uses HSB as open-drain busy indicator with internal 100 kΩ pull-up.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar nvSRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STK14C88-3JF50 | 512 K × 16, 35 ns access, 3.3 V ±10%, 100K STORE cycles, no HSB pin | Lacks hardware STORE trigger and busy indication; relies solely on software STORE or power-loss detection | Choose when system-level STORE coordination is handled entirely in firmware and timing margin allows 35 ns latency |
| FM22L16-55-TG | 2 Mbit (128 K × 16), 55 ns access, 3.3 V, ferroelectric RAM (FRAM), unlimited STORE endurance | Lower density, slower access, no AutoStore capacitor dependency, but infinite STORE cycles | Prefer for applications requiring frequent parameter logging (>1M saves/year) where 55 ns latency is acceptable |
Compared with STK14C88-3JF50 and FM22L16-55-TG, CY14B108N-ZSP25XI uniquely balances 25 ns speed, 8 Mbit density, hardware-managed STORE via HSB, and deterministic VCAP-powered AutoStore - making it optimal for real-time industrial systems needing fast, reliable, and autonomous nonvolatile state capture.

FAQ
What is the function of the VCAP pin, and what capacitor value is required?
The VCAP pin supplies energy for automatic STORE during VCC dropout. A 0.1 µF ceramic capacitor must be connected between VCAP and VSS, placed within 10 mm of the package per layout guidelines. This capacitor charges from VCC during normal operation and discharges to power the STORE circuit when VCC falls below VSWITCH (2.7 V). Using a smaller capacitor risks incomplete STORE and data corruption.
How does the HSB pin operate during STORE and RECALL cycles?
HSB is an open-drain pin with internal 100 kΩ pull-up. It is driven LOW by the device during active STORE or RECALL to signal busy status. Externally pulling HSB LOW initiates a hardware STORE, provided at least one write has occurred since the last STORE/RECALL. After completion, HSB is actively driven HIGH for tHHHD (100 ns min), then held HIGH by the weak pull-up. It must not be left floating.
Can CY14B108N-ZSP25XI be used in ×8 mode, or is it strictly ×16?
CY14B108N is specified exclusively for 512 K × 16 organization. The CY14B108L variant supports 1024 K × 8. Pinout, address mapping (A0–A18), and data bus (DQ0–DQ15) are fixed for ×16 operation. BHE and BLE pins are present and functional only in this configuration; attempting ×8 use violates the device's electrical and timing specifications.
Is AutoStore disable supported, and how is it implemented?
AutoStore cannot be permanently disabled in hardware. However, the datasheet errata confirms the "AutoStore Disable" software feature does not function. To prevent unintended STORE, omit the VCAP capacitor and ensure HSB remains unasserted - but this voids AutoStore capability. Systems requiring conditional STORE must rely on HSB control or software STORE only, with full awareness that power-loss STORE will not occur without VCAP.
