Product details
Overview
CY14V104LA-BA45XIT from Infineon Technologies (formerly Cypress) is a 4-Mbit non-volatile SRAM organized as 512 K × 8, featuring QuantumTrap™ non-volatile storage, 45 ns access time, 3.0–3.6 V core supply (VCC), and 1.65–1.95 V I/O supply (VCCQ). It performs automatic STORE on power-down using an external VCAP capacitor and supports software/hardware-initiated STORE/RECALL in industrial temperature range (–40°C to +85°C).
For engineers reviewing the CY14V104LA-BA45XIT datasheet, CY14V104LA-BA45XIT pinout, CY14V104LA-BA45XIT application, or CY14V104LA-BA45XIT equivalent, key selection criteria include AutoStore timing under voltage droop, HSB-driven hardware store control, VCAP sizing for reliable 1-million STORE endurance, and FBGA-48 pin compatibility with legacy Cypress nvSRAM designs.
Technical Context
This nvSRAM integrates standard SRAM cells with parallel QuantumTrap non-volatile elements per cell, enabling simultaneous STORE/RECALL across all 524,288 bytes without block erasure. The architecture decouples volatile read/write (infinite cycles) from non-volatile STORE (1 million cycles) and RECALL (infinite cycles), with data retention guaranteed for 20 years at 85°C.
STORE is triggered by three independent mechanisms: AutoStore on VCC drop below VSWITCH (using charge from VCAP), hardware STORE via HSB pin assertion, or software STORE via six-address sequence. RECALL occurs automatically on power-up or via software command, with HSB signaling busy status during both operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 4 Mbit (512 K × 8 organization); enables direct replacement of standard 512 KB SRAM in legacy systems without address/data bus redesign. |
| Access Time | 45 ns max; ensures compatibility with 22 MHz system clocks and meets timing margins for industrial microcontroller interfaces. |
| STORE Endurance | 1 million cycles to QuantumTrap; defines maximum field-replaceable event count before wear-out, critical for logging or configuration backup applications. |
| Data Retention | 20 years at +85°C; guarantees long-term data integrity in unpowered storage without battery or external NVM. |
| VCC Operating Range | 3.0 V to 3.6 V; matches standard 3.3 V rail tolerances and avoids level-shifting in mixed-voltage systems. |
| VCCQ Range | 1.65 V to 1.95 V; supports low-voltage I/O interfacing with modern SoCs and FPGAs while maintaining signal integrity. |
| Temperature Range | –40°C to +85°C; qualified for industrial control, motor drives, and factory automation environments. |
Pinout & Package
Package: 48-ball fine-pitch ball grid array (FBGA), 6 mm × 8 mm, 0.8 mm pitch, RoHS-compliant, lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Input | 19-bit address bus for 512 K × 8 mode; A18 used only in ×8 configuration; no A18 in ×16 mode. |
| DQ0–DQ7 | Bidirectional Data I/O | 8-bit data bus; tri-stated when OE HIGH or during STORE/RECALL; shared for read/write in standard SRAM protocol. |
| WE, CE, OE | Control Inputs | Active-low write enable, chip enable, output enable; compatible with standard SRAM timing and MPU bus protocols. |
| HSB | Hardware Store Busy | Open-drain status pin: driven LOW during STORE/RECALL; pulled HIGH internally (100 kΩ) post-operation; used to trigger or monitor store events. |
| VCAP | AutoStore Capacitor Supply | Connects to external 0.1 µF capacitor; provides energy for single STORE operation during VCC dropout; must be present if AutoStore enabled. |
| VCC / VCCQ / VSS | Power Terminals | VCC = core logic (3.0–3.6 V); VCCQ = I/O buffers (1.65–1.95 V); VSS = common ground reference for both domains. |
Key Features
| Feature | Design Value |
|---|---|
| Hands-off AutoStore | Automatic STORE initiated on VCC drop below VSWITCH using charge from external VCAP capacitor-no firmware intervention required. |
| Parallel STORE/RECALL | All 524,288 memory cells transfer data simultaneously, eliminating block erase delays and ensuring deterministic <10 ms STORE time. |
| Three-Mode STORE Control | Supports hardware (HSB pin), software (6-address sequence), and AutoStore-enables flexible integration into safety-critical or resource-constrained systems. |
| Independent Endurance Ratings | Infinite SRAM reads/writes + infinite RECALL cycles + 1 million STORE cycles-decouples volatile performance from non-volatile wear limits. |
| Industrial Voltage Tolerance | VCCQ range (1.65–1.95 V) allows direct interface with 1.8 V FPGA I/O banks or low-power microcontrollers without level shifters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar non-volatile SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY14V104NA-BA45XIT | Same die, 256 K × 16 organization; requires 16-bit data bus and different address mapping (A0–A17 only). | Used where 16-bit microprocessor or DSP interfaces dominate; not pin-compatible due to DQ15–DQ0 vs DQ7–DQ0 layout and BHE/BLE presence. | Select only when system uses 16-bit bus width and can accommodate revised address/data routing. |
| FM24V10-G | F-RAM-based 1 Mbit (128 K × 8); 130 ns access; single 2.7–3.6 V supply; no VCAP required; unlimited STORE endurance. | Lacks AutoStore on power-loss; relies on host-controlled STORE; lower density and slower access than CY14V104LA. | Choose for ultra-high endurance (>1014 cycles) in low-write-rate applications where deterministic STORE timing is less critical than endurance. |
Compared with CY14V104NA-BA45XIT, the CY14V104LA-BA45XIT offers native 8-bit bus compatibility and simpler layout; versus FM24V10-G, it delivers faster access, integrated AutoStore, and higher density-but requires careful VCAP design and accepts lower STORE cycle count.

FAQ
What is the minimum VCAP capacitor value required for reliable AutoStore operation?
The datasheet specifies a 0.1 µF ceramic capacitor rated for ≥10 V, placed within 10 mm of the VCAP pin and connected directly to VSS. Using undersized or high-ESR capacitors risks incomplete STORE execution and data corruption during VCC dropout. The internal regulator charges VCAP to ~2.5 V; actual required capacitance depends on system VCC droop profile and STORE current draw.
Can CY14V104LA-BA45XIT be used in a 16-bit data bus configuration?
No-it is strictly a 512 K × 8 device with DQ0–DQ7 only. Attempting to connect DQ8–DQ15 will result in floating pins and potential noise coupling. For 16-bit systems, use CY14V104NA-BA45XIT, which has full DQ0–DQ15, BHE/BLE controls, and 256 K × 16 organization-though pinout and address mapping differ significantly.
How does the HSB pin behave during a software-initiated STORE?
HSB is driven LOW immediately upon software STORE initiation and remains LOW until the operation completes (~10 ms). After completion, it is actively driven HIGH for tHHHD (≤100 ns), then held HIGH by the internal 100 kΩ pull-up. This behavior is identical for hardware and AutoStore, enabling unified busy-wait polling across all STORE modes.
Is there a risk of data corruption if AutoStore is enabled but no VCAP capacitor is installed?
Yes-enabling AutoStore without VCAP causes the device to attempt STORE using insufficient residual charge, resulting in partial or failed writes and potential memory cell corruption. The datasheet mandates disabling AutoStore via software sequence (page 6) if VCAP is omitted. Default factory setting enables AutoStore, so verification and configuration are mandatory during system bring-up.
