Product details
Overview
CY14B104L-ZS45XIT from Cypress Semiconductor is a 4 Mbit nonvolatile SRAM (nvSRAM) with QuantumTrap® technology, organized as 512K × 8, 45 ns access time, single 3V (+20% to –10%) supply, and integrated AutoStore® on power loss. It serves as drop-in SRAM replacement in systems requiring persistent data retention without external battery or EEPROM backup - e.g., industrial PLCs, medical data loggers, and telecom control cards.
For engineers reviewing the CY14B104L-ZS45XIT datasheet, CY14B104L-ZS45XIT pinout, CY14B104L-ZS45XIT application, or CY14B104L-ZS45XIT equivalent, key selection criteria include VCAP capacitor sizing for reliable AutoStore, HSB pin handling during power sequencing, software STORE/RECALL address sequence compliance, and x8 vs. x16 configuration compatibility with host bus timing.
Technical Context
This nvSRAM integrates parallel SRAM and QuantumTrap nonvolatile cells per bit, enabling simultaneous STORE/RECALL across all memory locations. It supports three STORE initiation methods: hardware (HSB pin), software (6-address read sequence), and automatic (on VCC drop below VSWITCH).
During AutoStore, internal regulation charges an external VCAP capacitor from VCC; when VCC falls, the capacitor powers a full-array STORE in ≤20 ms. RECALL occurs automatically at power-up or via software sequence, restoring data to SRAM in ≤15 ms while preserving nonvolatile cell integrity for ≥20 years.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 4 Mbit (512K × 8 organization) |
| Access Time | 45 ns - defines maximum clock-to-data delay for synchronous read/write cycles |
| Supply Voltage | 3.0 V ±10% - operates within industrial 2.7–3.6 V range without level shifters |
| STORE Endurance | 200,000 cycles - limits total nonvolatile write events over product lifetime |
| Data Retention | 20 years at +85°C - guaranteed nonvolatile data hold without refresh or power |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded control environments |
| AutoStore Trigger | VCC < VSWITCH (2.5 V typ.) - initiates capacitor-powered STORE before system brownout |
Pinout & Package
Package: 48-ball FBGA (9 mm × 9 mm, 0.8 mm pitch), RoHS-compliant, lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Input | 19-bit address bus for 512K × 8 addressing; A18 used only in x8 mode |
| DQ0–DQ7 | Bidirectional Data I/O | 8-bit data bus shared for read/write; tri-stated when OE HIGH or during STORE/RECALL |
| WE, CE, OE | Control Inputs | Active-low write enable, chip enable, output enable - standard SRAM timing interface |
| VCAP | Power Supply Terminal | Connects external 0.1 µF storage capacitor; powers STORE operation during VCC collapse |
| HSB | I/O with Open-Drain | Indicates STORE busy (LOW); also initiates hardware STORE when externally pulled LOW |
| VCC / VSS | Power / Ground | Single 3V supply rail; requires local decoupling per JEDEC FBGA layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| QuantumTrap® Nonvolatile Cell | Embedded per-bit NV element enables true infinite SRAM reads/writes while retaining 20-year data persistence |
| AutoStore® on Power Loss | Zero-software, capacitor-backed STORE triggered autonomously at VCC < 2.5 V - eliminates external supervision circuitry |
| Software-Controlled STORE/RECALL | 6-address read sequence (e.g., 0x4E38 → 0x8FC0) enables deterministic nonvolatile operations without hardware intervention |
| Hardware Store Busy (HSB) Pin | Open-drain status signal provides real-time STORE progress visibility and safe synchronization with host processor |
| Byte-Level Control (x16 mode) | BHE/ BLE pins allow independent 8-bit writes in 16-bit bus configurations - critical for legacy MPU compatibility |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar nonvolatile SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STK14C88-45I-M1F | 4 Mbit nvSRAM, 45 ns, 3V, but uses SONOS nonvolatile technology; no HSB pin; requires external voltage monitor for STORE trigger | Lacks hardware store acknowledgment and AutoStore autonomy - demands additional supervisor IC and firmware logic | Select only if existing design already uses STK14C88 footprint and can accommodate added supervision circuitry |
| FM24V04-G | 4 Mbit F-RAM, 3V, 55 ns, unlimited endurance, but lacks AutoStore and requires continuous VDD monitoring for write protection | No built-in power-loss STORE; relies on host MCU to detect brownout and initiate save - increases firmware complexity and failure risk | Prefer where high write-cycle count dominates over power-loss resilience; not suitable for unattended systems |
Compared with STK14C88-45I-M1F and FM24V04-G, CY14B104L-ZS45XIT uniquely delivers autonomous capacitor-backed STORE, real-time HSB feedback, and software-initiated nonvolatile control - making it the only option that fully replaces battery-SRAM without compromising reliability or increasing system-level validation burden.

FAQ
What capacitor value is required on the VCAP pin for reliable AutoStore operation?
A 0.1 µF X7R ceramic capacitor rated for ≥10 V must be placed directly between VCAP and VSS, with minimal trace length and no series resistance. This value ensures sufficient charge to complete a full 4 Mbit STORE within the tSTORE specification (≤20 ms) under worst-case VCC droop conditions down to 2.0 V.
Can CY14B104L-ZS45XIT be used in x16 mode?
No - CY14B104L-ZS45XIT is factory-configured for 512K × 8 (x8) organization. The CY14B104N variant supports 256K × 16 (x16); pinout, timing, and byte-enable (BHE/ BLE) behavior differ significantly between the two, making them non-interchangeable without PCB redesign.
How does the HSB pin behave during a software-initiated STORE?
During software STORE, HSB transitions from HIGH to open-drain LOW within 100 ns after the sixth address read (0x8FC0), remains LOW for the full tSTORE duration (max 20 ms), then returns HIGH. Host firmware must poll HSB or use interrupt-on-fall to synchronize post-STORE execution - no timeout fallback is provided.
Is the 45 ns access time guaranteed over the full industrial temperature range?
Yes - the 45 ns tAA (address-access time) is specified and tested from –40°C to +85°C at VCC = 2.7 V to 3.6 V. This includes margin for process variation and aging; no derating is required for thermal or voltage extremes within the published operating conditions.
