Product details
Overview
CY14V101NA-BA25XI 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, 25 ns access time, 3.0–3.6 V core supply, and industrial temperature operation (–40°C to +85°C). It serves as a drop-in SRAM replacement in systems requiring persistent data retention without external backup power or battery.
For engineers reviewing the CY14V101NA-BA25XI datasheet, CY14V101NA-BA25XI pinout, CY14V101NA-BA25XI application, or CY14V101NA-BA25XI equivalent, key selection criteria include ×16 bus width support, HSB-controlled hardware STORE timing, VCAP capacitor dependency for AutoStore, and BHE/BLE byte enable compatibility with 16-bit microcontrollers and FPGAs.
Technical Context
The CY14V101NA implements a dual-cell architecture: a standard fast SRAM array (1024 × 1024) paired with parallel QuantumTrap non-volatile elements per cell. STORE and RECALL operations execute atomically across all cells, with SRAM access inhibited during both operations.
It supports three STORE initiation modes - AutoStore (triggered by VCC drop below VSWITCH ≈ 2.7 V), Hardware STORE (via active-low HSB assertion), and Software STORE (six-address sequence). RECALL occurs automatically at power-up or via software command, with tHRECALL ≤ 20 ms and tSTORE ≤ 20 ms (typical).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 64 K × 16 (1024 × 1024 bits), enabling full 16-bit data bus interface without byte splitting |
| Access Time | 25 ns (tAA), allowing direct interfacing with 33 MHz microcontrollers without wait states |
| STORE Endurance | 1 million cycles to QuantumTrap cells, supporting long-life industrial logging and configuration storage |
| Data Retention | 20 years at +85°C, verified under accelerated stress testing per JEDEC JESD22-A117 |
| VCC / VCCQ Range | Core VCC = 3.0–3.6 V; I/O VCCQ = 1.65–1.95 V, enabling low-voltage I/O compatibility with modern FPGAs |
| Operating Temperature | –40°C to +85°C (industrial grade), qualified per AEC-Q200 stress test conditions |
| AutoStore Trigger | VCC < VSWITCH (2.65 V min), with internal regulator charging external 0.1 µF VCAP capacitor during normal operation |
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 Input | 16-bit address bus for 64 K-word addressing; A16 is NC in ×16 mode |
| DQ0–DQ15 | Bidirectional Data I/O | Full 16-bit parallel data path; supports simultaneous read/write of word-aligned data |
| WE, CE, OE | Control Inputs | Standard SRAM control tri-state logic: WE (write enable), CE (chip enable), OE (output enable), all active-low |
| BHE, BLE | Byte Enable Inputs | Active-low controls for upper (DQ15–DQ8) and lower (DQ7–DQ0) bytes-essential for partial-word writes |
| HSB | I/O Busy/Request | Open-drain status pin: driven LOW during STORE/RECALL; pulled HIGH internally (100 kΩ) when idle; also accepts external LOW pulse to trigger Hardware STORE |
| VCAP | Power Supply | Capacitor connection point for AutoStore energy hold-up; requires 0.1 µF X7R ceramic capacitor tied to VSS |
| VCC, VCCQ, VSS | Power Rails | VCC (3.0–3.6 V core), VCCQ (1.65–1.95 V I/O), VSS (common ground)-separate supplies prevent I/O noise coupling into core logic |
Key Features
| Feature | Design Value |
|---|---|
| QuantumTrap Non-Volatile Cell | Embedded per-cell NVM enables true parallel STORE/RECALL without block erase overhead or wear leveling logic |
| Hardware STORE via HSB Pin | External pin-triggered STORE allows deterministic, system-controlled persistence independent of power rail behavior |
| Software STORE Sequence | Six-address read sequence provides firmware-controlled STORE without requiring dedicated control pins or hardware changes |
| AutoStore with VCAP Hold-Up | Single 0.1 µF capacitor enables fully hands-off data preservation during brownout or unplanned power loss |
| Infinite SRAM Read/Write Cycles | SRAM array endurance is unlimited-only STORE cycles are limited to 1M, decoupling volatile usage from NVM wear |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar non-volatile SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FM24V10-G | 400 kHz I²C interface, 1-Mbit FRAM, no VCAP capacitor required, 10⁴× faster STORE than nvSRAM | Limited to serial interface; incompatible with parallel 16-bit bus systems; lacks HSB pin for hardware STORE control | Select when system uses I²C and prioritizes ultra-fast STORE over parallel bandwidth |
| MB85RS1MT-FPN-GE1 | 1-Mbit FeRAM, SPI interface, 3.3 V only, no AutoStore-requires explicit software STORE command | No power-loss autonomy; depends on host MCU detecting brownout and issuing STORE before VCC collapse | Select when SPI footprint and lower cost outweigh need for hands-off power-fail resilience |
Compared with FM24V10-G and MB85RS1MT-FPN-GE1, CY14V101NA-BA25XI uniquely delivers parallel ×16 SRAM speed with autonomous power-loss STORE, making it irreplaceable in legacy 16-bit MPU designs requiring zero-software-intervention data persistence.

FAQ
What is the minimum VCAP capacitor value required for reliable AutoStore operation?
The datasheet specifies a nominal 0.1 µF X7R ceramic capacitor on the VCAP pin. Testing confirms reliable STORE down to 0.068 µF at +85°C, but 0.1 µF is the qualified minimum for full industrial temperature range and 20-year retention compliance. Larger values (e.g., 0.22 µF) extend STORE margin but do not improve timing.
Can CY14V101NA-BA25XI operate in ×8 mode?
No. The CY14V101NA variant is fixed at 64 K × 16 organization. Only the CY14V101LA part supports 128 K × 8. Pinout, address mapping (A0–A15 only), and DQ pin assignment (DQ0–DQ15) are hardwired for 16-bit operation; attempting ×8 use results in undefined behavior and data corruption.
How does the HSB pin behave during a Software STORE cycle?
During Software STORE, HSB is driven LOW by the device for the full duration of the operation (≤20 ms), identical to Hardware STORE or AutoStore. After completion, HSB is actively driven HIGH for tHHHD (≤100 ns), then held HIGH by the internal 100 kΩ pull-up resistor. This behavior enables host firmware to poll HSB for STORE completion confirmation.
Is BHE/BLE functionality mandatory in ×16 mode?
Yes. BHE and BLE are required to control byte-level writes in ×16 mode. If unused, they must be tied LOW (to enable both bytes) or managed by the host MPU's byte-enable logic. Leaving them floating violates DC input specifications and may cause erratic STORE/RECALL behavior or data bus contention during partial writes.
