Product details
Overview
CY14V101NA-BA45XIT from Infineon Technologies (formerly Cypress) is a 1-Mbit non-volatile SRAM organized as 64 K × 16, featuring QuantumTrap technology for automatic STORE on power loss, software-controlled STORE/RECALL, and industrial-grade operation. It supports 45 ns access time, dual VCC/VCCQ supply (3.0–3.6 V core / 1.65–1.95 V I/O), and delivers 20-year data retention with 1 million STORE cycles.
For engineers reviewing the CY14V101NA-BA45XIT datasheet, CY14V101NA-BA45XIT pinout, CY14V101NA-BA45XIT application, or CY14V101NA-BA45XIT equivalent, key selection criteria include ×16 bus interface support, HSB-driven hardware STORE control, VCAP-backed AutoStore reliability, and FBGA-48 packaging for high-density industrial PCB layouts.
Technical Context
The CY14V101NA implements a parallel architecture where each memory cell integrates a standard SRAM array and a QuantumTrap non-volatile element. STORE and RECALL operations execute in parallel across all cells, with SRAM access inhibited during non-volatile transfers.
It supports three STORE initiation modes: AutoStore triggered by VCC drop below VSWITCH (using charge from VCAP), Hardware STORE via active-low HSB assertion, and Software STORE via six-address sequence. RECALL occurs automatically at power-up or via software command, restoring full 64 K × 16 content to SRAM in tHRECALL ≤ 20 ms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 64 K × 16 (1 Mbit total); enables 16-bit wide data bus interfacing without external byte multiplexing. |
| Access Time | 45 ns; ensures compatibility with legacy microcontrollers and FPGAs operating at ≤22 MHz asynchronous timing. |
| VCC Core Supply | 3.0 V to 3.6 V; matches standard 3.3 V system rails while tolerating ±10% regulation drift. |
| VCCQ I/O Supply | 1.65 V to 1.95 V; supports low-voltage 1.8 V logic interfaces, reducing signal integrity risk and power consumption. |
| Data Retention | 20 years at TA = −40 °C to +85 °C; guarantees long-term firmware/state storage in unpowered industrial edge nodes. |
| STORE Endurance | 1 million cycles; sufficient for daily firmware update logging over 27 years of continuous operation. |
| AutoStore Trigger | VCC < VSWITCH (typ. 2.7 V); initiates reliable STORE before system brownout causes logic corruption. |
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–A15 | Address inputs | Select one of 65,536 16-bit words; A16 is NC in ×16 mode, enabling pin-compatible migration path to larger densities. |
| DQ0–DQ15 | Bidirectional data I/O | Full 16-bit parallel data path; eliminates need for external data multiplexers in 16-bit MCU/FPGA designs. |
| WE, CE, OE | Control inputs (active LOW) | Standard SRAM control protocol; interoperable with ARM Cortex-M, Renesas RX, and Xilinx Zynq PS interfaces. |
| BHE, BLE | Byte enable inputs | Enable upper/lower 8 bits independently; supports mixed 8/16-bit peripheral access without glue logic. |
| HSB | Hardware STORE busy / trigger | Open-drain status output and STORE request input; enables deterministic STORE timing and MPU synchronization. |
| VCAP | AutoStore capacitor connection | Connects to 0.1 µF ceramic capacitor; provides regulated energy for single STORE execution during power failure. |
| VCC, VCCQ, VSS | Power supply terminals | Separate core and I/O supplies allow independent voltage domain management and noise isolation. |
Key Features
| Feature | Design Value |
|---|---|
| QuantumTrap non-volatile cell | Enables true nvSRAM behavior - infinite SRAM reads/writes plus 1M STOREs - without battery or EEPROM emulation overhead. |
| Hardware STORE via HSB pin | Allows deterministic, externally initiated STORE with status feedback, critical for safety-critical shutdown sequences. |
| Software STORE/RECALL | Permits controlled non-volatile updates during runtime (e.g., configuration save before reconfiguration), avoiding power-loss dependency. |
| AutoStore with VCAP | Eliminates external power-fail detection circuitry; stores last valid state autonomously when main supply collapses. |
| Industrial temperature range | Operates reliably from −40 °C to +85 °C, validated for deployment in motor drives, PLC backplanes, and outdoor gateways. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar non-volatile SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY14V101LA-BA45XIT | Same die, ×8 organization (128 K × 8); identical timing, voltage, and endurance specs. | Requires 8-bit data bus; unsuitable for 16-bit MPU/FPGA interfaces without external demultiplexing. | Select only when system uses 8-bit parallel bus or requires pin-compatible upgrade from legacy CY14B101LA. |
| FM24V10-G | F-RAM-based (1 Mbit, 64 K × 16); unlimited STORE cycles but slower 55 ns access; no VCAP required. | Lacks AutoStore on power loss; relies on host-controlled STORE, increasing firmware complexity and failure risk. | Prefer for high-cycle-count logging where power-fail STORE is managed externally; avoid where deterministic autonomous STORE is mandatory. |
Compared with CY14V101LA-BA45XIT, the CY14V101NA offers native 16-bit bus efficiency and eliminates byte-enable logic; versus FM24V10-G, it provides guaranteed power-loss STORE without host coordination - essential for fail-safe industrial control.

FAQ
What is the minimum VCAP capacitance required for reliable AutoStore operation?
The datasheet specifies a nominal 0.1 µF ceramic capacitor on the VCAP pin. This value ensures sufficient stored energy to complete one full STORE cycle when VCC drops below VSWITCH (2.7 V typ.). Using a lower-value capacitor risks incomplete STORE and data corruption; higher values (e.g., 0.22 µF) improve margin but do not reduce tSTORE duration.
Can CY14V101NA-BA45XIT operate with VCCQ = 1.8 V and VCC = 3.3 V simultaneously?
Yes - the device is explicitly rated for VCCQ = 1.65–1.95 V and VCC = 3.0–3.6 V concurrently. This dual-supply architecture isolates I/O signaling from core logic, allowing direct interface with 1.8 V FPGAs or microcontrollers while maintaining robust 3.3 V SRAM cell stability.
How does the HSB pin behave during a Software STORE cycle?
During Software STORE, HSB is driven LOW by the device to indicate STORE busy status, exactly as during Hardware STORE or AutoStore. It remains LOW for tHSTORE (max 20 ms), then transitions HIGH - first with strong drive (tHHHD), then sustained by internal 100 kΩ pull-up - signaling completion and readiness for next SRAM access.
Is BHE/ BLE functionality active in ×8 configuration?
No - BHE and BLE pins are reserved and must be left unconnected (NC) in ×8 mode. The datasheet confirms these signals apply exclusively to the 64 K × 16 organization. In ×8 mode, DQ0–DQ7 constitute the full data bus, and byte enable logic is irrelevant.
