Product details
Overview
CY14B104L-BA25XIT from Cypress Semiconductor is a 4 Mbit (512K × 8) nonvolatile SRAM with QuantumTrap® technology, operating at 25 ns access time and single 3V ±10% supply. It integrates fast SRAM with on-chip nonvolatile storage, enabling automatic STORE on power loss via VCAP capacitor and software/hardware-initiated RECALL. Used in industrial control systems requiring persistent memory without battery backup.
For engineers reviewing the CY14B104L-BA25XIT datasheet, CY14B104L-BA25XIT pinout, CY14B104L-BA25XIT application, or CY14B104L-BA25XIT equivalent, key selection criteria include AutoStore timing (tSTORE = 15 ms), HSB-driven hardware store coordination, VCAP capacitor sizing (0.1 µF), and x8 configuration compatibility with legacy 8-bit microcontrollers.
Technical Context
The device implements a dual-cell architecture: standard SRAM for infinite read/write cycles and parallel QuantumTrap nonvolatile elements for data retention. STORE and RECALL operations execute in parallel across all cells, with SRAM access inhibited during nonvolatile transfers.
AutoStore triggers automatically when VCC drops below VSWITCH (2.7 V), using charge stored on the external VCAP capacitor. Hardware STORE is initiated by pulling HSB low, while software STORE/RECALL use six-address CE-controlled read sequences - no write cycles involved.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 4 Mbit (512K × 8), fixed x8 organization - matches 8-bit data bus interfaces without byte enable logic. |
| Access Time | 25 ns - enables direct interfacing with 33 MHz microcontrollers without wait states. |
| Supply Voltage | 3.0 V ±10% (2.7–3.6 V) - compatible with standard 3.3 V I/O domains and eliminates need for voltage regulators. |
| STORE Cycles | 200,000 - defines endurance limit for nonvolatile writes; exceeds typical industrial logging requirements over 10+ years. |
| Data Retention | 20 years at +85°C - guarantees long-term data integrity in unpowered storage for medical or infrastructure applications. |
| VCAP Capacitor | 0.1 µF ceramic - provides sufficient energy for one full STORE operation during brown-out; requires no external charging circuitry. |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments including factory automation and transportation electronics. |
Pinout & Package
Package: 48-ball FBGA (7 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; unused pins are NC in x16 variants. |
| 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, and output enable - standard SRAM timing interface compatible with ARM Cortex-M, PIC, and legacy 8051 controllers. |
| VCAP | Power Supply Terminal | Connects to 0.1 µF capacitor; internal regulator charges it from VCC and powers STORE operation during power loss. |
| HSB | Hardware Store Busy | Open-drain status/output: driven LOW during STORE/RECALL; pulled LOW externally to initiate hardware STORE; internally pulled HIGH if unconnected. |
| VCC / VSS | Power / Ground | Single 3V supply domain; VSS must be low-impedance ground plane connection to ensure stable STORE timing. |
Key Features
| Feature | Design Value |
|---|---|
| AutoStore on Power Loss | Zero-software intervention STORE triggered by VCC drop below 2.7 V; uses on-chip VCAP regulation and capacitor hold-up. |
| Hardware STORE Initiation | HSB pin allows deterministic, externally synchronized STORE - critical for safety-critical shutdown sequencing in PLCs. |
| Software STORE/RECALL | Six-address CE-read sequence (no writes) enables firmware-controlled persistence without hardware modification. |
| QuantumTrap Nonvolatility | 20-year data retention at +85°C and 200K STORE cycles - eliminates battery replacement and leakage concerns of nvSRAM alternatives. |
| x8 Configuration Only | Dedicated 512K × 8 layout - simplifies PCB routing vs. x16 parts; avoids BHE/BLE logic and reduces signal count in 8-bit systems. |
Applications
| Industrial PLC Data Logging | Medical Device Parameter Storage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar nonvolatile SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STK14C88-3LF3A | 4 Mbit x8 nvSRAM, 35 ns access, 3.3 V, 44-pin TSOP II - lacks HSB pin and AutoStore; requires external controller for STORE initiation. | No hardware STORE coordination; unsuitable for systems needing deterministic brown-out response without firmware intervention. | Select only if board space permits larger TSOP package and system firmware can manage STORE timing via CE/OE toggling. |
| FM24V04-G | 4 Mbit F-RAM, 3.3 V, 48-BGA - unlimited STORE cycles, but 55 ns access time and no AutoStore; relies on host MCU to trigger save. | Higher endurance but slower access and no autonomous power-loss response - increases firmware complexity and risk of data loss during reset. | Prefer where write frequency exceeds 200K cycles/year; avoid where deterministic STORE timing or zero-software fail-safe is required. |
Compared with STK14C88-3LF3A and FM24V04-G, CY14B104L-BA25XIT uniquely delivers 25 ns speed, autonomous AutoStore, and HSB-synchronized hardware STORE - making it the only choice for industrial systems requiring guaranteed data persistence without CPU involvement during power collapse.

FAQ
What is the minimum VCAP capacitor value required for reliable AutoStore operation?
The datasheet specifies a 0.1 µF ceramic capacitor on the VCAP pin. This value ensures sufficient charge to complete one full STORE operation (tSTORE = 15 ms) when VCC drops below 2.7 V. Larger capacitors do not improve reliability but may increase power-up time; X7R dielectric is recommended for temperature stability.
Can CY14B104L-BA25XIT be used in x16 mode?
No. CY14B104L is strictly a 512K × 8 (x8) device. The CY14B104N variant supports x16 configuration. Pinout, address mapping (A0–A18), and data bus (DQ0–DQ7 only) are fixed for x8 operation - attempting x16 interfacing will result in incorrect addressing and data corruption.
How does the HSB pin behave during a software-initiated STORE?
During software STORE, HSB is driven LOW by the device after the sixth address read (0x8FC0) and remains LOW until tSTORE (15 ms) completes. It functions identically to hardware STORE - providing external visibility into nonvolatile operation progress and blocking SRAM access until completion.
Is the 200,000 STORE cycle rating per cell or for the entire array?
The 200,000 STORE cycles is a device-level endurance specification - meaning the entire 512K × 8 array can undergo 200,000 full STORE operations before potential nonvolatile element degradation. It is not per-cell; QuantumTrap technology ensures uniform wear across all cells due to parallel architecture.
