Product details
Overview
CY14B104LA-BA45XIT from Cypress Semiconductor is a 4-Mbit non-volatile SRAM (nvSRAM) with QuantumTrap technology, organized as 512K × 8, supporting 45 ns access time, single 3 V (+20% / –10%) supply, and industrial temperature range (–40°C to +85°C). It performs automatic STORE on power-down using an external VCAP capacitor and supports software/hardware-initiated STORE/RECALL cycles for mission-critical data retention in systems requiring zero-battery backup.
For engineers reviewing the CY14B104LA-BA45XIT datasheet, CY14B104LA-BA45XIT pinout, CY14B104LA-BA45XIT application, or CY14B104LA-BA45XIT equivalent, key selection considerations include AutoStore timing dependency on VCAP capacitance, HSB pin behavior during STORE busy state, ×8 vs ×16 configuration compatibility, and 1 million STORE endurance versus infinite RECALL cycles.
Technical Context
This nvSRAM integrates standard SRAM cells with parallel QuantumTrap non-volatile elements per cell, enabling simultaneous STORE/RECALL across all memory locations. The architecture decouples volatile read/write performance (20–45 ns access) from non-volatile endurance (1M STOREs, 20-year retention).
STORE operations are conditionally triggered: AutoStore activates when VCC drops below VSWITCH and VCAP supplies hold-up energy; Hardware STORE initiates on HSB low assertion only if at least one write occurred since last STORE/RECALL; Software STORE bypasses that write-latch requirement via address-sequence command.
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 in high-speed SRAM read cycles |
| Supply Voltage | 3.0 V ±10% / +20% - compatible with standard 3.3 V rail with margin for brown-out tolerance |
| Data Retention | 20 years at +85°C - guaranteed non-volatile data survival without power or refresh |
| STORE Endurance | 1 million cycles - limits total number of STORE operations before QuantumTrap wear-out |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments without derating |
| AutoStore Support | Capacitor-backed (VCAP pin) - requires external 0.1 µF ceramic capacitor for hands-off power-loss STORE |
Pinout & Package
Package: 44-pin Thin Small Outline Package (TSOP II), Type II, RoHS-compliant, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Input | 19-bit address bus for 512K × 8 addressing; A17/A18 used only in ×8 mode |
| DQ0–DQ7 | Bidirectional Data I/O | 8-bit data bus; tristated when OE HIGH or during STORE/RECALL |
| WE | Write Enable (Active LOW) | Controls write initiation; must be stable before and during write cycle; pull-up recommended at power-up |
| CE | Chip Enable (Active LOW) | Enables device operation; deassertion places outputs in high-impedance state |
| OE | Output Enable (Active LOW) | Activates output drivers during read; must be HIGH during write to avoid bus contention |
| VCAP | AutoStore Capacitor Supply | Connects to 0.1 µF ceramic capacitor; powers internal STORE circuitry during VCC collapse |
| HSB | Hardware STORE Busy | Open-drain status signal: driven LOW during STORE; pulled HIGH post-completion (100 kΩ internal) |
| VCC / VSS | Power / Ground | Single 3 V supply; VSS must be low-inductance connection to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| QuantumTrap Non-Volatile Cell | Embedded per-cell NV element enables parallel STORE/RECALL without external EEPROM or battery |
| AutoStore on Power-Down | Zero-software intervention STORE triggered by VCC drop below VSWITCH, using charge from VCAP |
| Three STORE Initiation Modes | Hardware (HSB pin), Software (address sequence), and AutoStore - provides design flexibility for fail-safe logging |
| Infinite SRAM Read/Write Cycles | Standard SRAM interface behavior preserved; no endurance limitation on volatile access |
| Industrial Temperature Range | –40°C to +85°C operation without derating - suitable for factory automation and transportation control units |

Equivalent & Alternatives
The following parts are listed as comparable options for similar non-volatile SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STK14C88-3AJ5F | 4-Mbit nvSRAM, 35 ns access, 5 V operation, no HSB pin, uses lithium battery backup | Requires battery replacement planning and failsafe battery voltage monitoring circuitry | Select when legacy 5 V systems demand pin-compatible upgrade and battery maintenance is acceptable |
| FM24V10-G | 1-Mbit F-RAM, 3 V, 45 ns, unlimited endurance, no STORE latency, no VCAP capacitor needed | Limited density (1 Mbit) and no AutoStore trigger on VCC drop - requires MCU-driven STORE on interrupt | Select when infinite STORE cycles outweigh density needs and deterministic low-latency writes are critical |
Compared with STK14C88-3AJ5F and FM24V10-G, CY14B104LA-BA45XIT uniquely combines 4-Mbit density, capacitor-backed AutoStore, and hardware-managed STORE/RECALL sequencing - making it optimal for industrial systems where battery-free reliability and power-loss transparency are mandatory.

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 charge to complete a full STORE cycle when VCC collapses below VSWITCH (typ. 2.7 V). Using lower capacitance risks incomplete STORE and data corruption; larger values extend hold-up time but do not improve reliability beyond specification. X7R dielectric with low ESR is recommended.
Can CY14B104LA-BA45XIT operate in ×16 mode?
No. CY14B104LA is exclusively a 512K × 8 device. The ×16 variant is CY14B104NA (256K × 16), which uses different pinouts, adds BHE/BLE signals, and omits HSB in the 44-pin TSOP II package. Pin compatibility does not imply functional equivalence - mixing part numbers risks address/data misalignment and failed STORE/RECALL.
How does the HSB pin behave during a Software STORE cycle?
During Software STORE, HSB is actively driven LOW by the device for the entire duration of the STORE operation (tSTORE, max 10 ms), then driven HIGH for tHHHD (100 ns min), after which it remains HIGH via internal 100 kΩ pull-up. This behavior is identical to Hardware STORE and AutoStore, enabling consistent system-level busy monitoring regardless of initiation method.
Is CY14B104LA-BA45XIT qualified for automotive applications?
CY14B104LA-BA45XIT is specified for industrial temperature range (–40°C to +85°C) and carries no AEC-Q100 qualification. While its operating range overlaps automotive cabin environments, it lacks automotive-specific reliability testing (e.g., HTOL, ESD, vibration). For automotive ECUs, Cypress recommends AEC-Q100-qualified variants like the CY14B104Q series, not this industrial-grade part.
