Product details
Overview
CY14B101NA-ZS45XIT from Infineon Technologies (formerly Cypress) is a 1-Mbit nonvolatile SRAM (nvSRAM) with QuantumTrap technology, organized as 64 K × 16, supporting 45 ns access time, single 3.0 V ±10% operation, and industrial temperature range (–40°C to +85°C). It performs automatic STORE on power-down using VCAP-supplied energy and supports software/hardware-initiated STORE/RECALL for mission-critical data retention in embedded control systems.
For engineers reviewing the CY14B101NA-ZS45XIT datasheet, CY14B101NA-ZS45XIT pinout, CY14B101NA-ZS45XIT application, or CY14B101NA-ZS45XIT equivalent, key selection factors include ×16 bus interface compatibility, HSB-controlled hardware STORE timing, VCAP capacitor sizing requirements, and BHE/BLE byte enable support for 16-bit microprocessor interfacing.
Technical Context
This nvSRAM integrates parallel SRAM and QuantumTrap nonvolatile storage per cell, enabling simultaneous STORE/RECALL across all 65,536 words without block erase or wear leveling. Its architecture decouples volatile read/write cycles (infinite endurance) from nonvolatile STORE operations (1 million cycles, 20-year retention).
AutoStore triggers when VCC drops below VSWITCH (~2.7 V), disconnecting VCAP from VCC and using stored charge to complete STORE within tSTORE (max 20 ms). Hardware STORE is initiated by pulling HSB LOW, while software STORE uses address-based command sequences-both inhibit SRAM access during execution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (64 K × 16 configuration) |
| Access Time | 45 ns - defines maximum clock rate for synchronous MPU interfaces without wait states |
| Supply Voltage | 3.0 V ±10% - compatible with standard 3.3 V LDOs with ±10% tolerance margin |
| Data Retention | 20 years at +85°C - ensures long-term firmware/state persistence in unpowered industrial equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar nonvolatile SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FM24V10-G | 1-Mbit F-RAM (45 ns access, 3 V, –40°C to +85°C); unlimited STORE endurance; no VCAP capacitor required | No power-loss STORE timing dependency; lower standby current; lacks HSB pin for hardware trigger | Choose for ultra-high STORE frequency or simplified power design; avoid if deterministic hardware-triggered STORE is required |
| MB85RS1MT-FPN-GE1 | 1-Mbit FRAM (35 ns access, 1.8–3.6 V); no VCAP; supports SPI interface only-not parallel ×16 | Serial interface reduces pin count but increases software overhead; incompatible with existing 16-bit MPU bus layout | Choose for space-constrained designs with SPI-capable MCUs; not suitable as drop-in replacement for parallel-bus systems |
Compared with FM24V10-G and MB85RS1MT-FPN-GE1, CY14B101NA-ZS45XIT uniquely delivers parallel ×16 interface, HSB-driven hardware STORE, and VCAP-based AutoStore-making it optimal for legacy MPU-based industrial controllers requiring deterministic, capacitor-backed power-loss recovery.

FAQ
What is the minimum VCAP capacitor value required for reliable AutoStore operation?
The datasheet specifies a minimum 4.7 µF tantalum capacitor on the VCAP pin, rated for ≥6.3 V, with ESR ≤ 1 Ω. Using a smaller or higher-ESR capacitor risks incomplete STORE during rapid VCC collapse, leading to data corruption. Ceramic capacitors are not recommended due to insufficient capacitance stability under bias.
Does CY14B101NA-ZS45XIT support both ×8 and ×16 configurations?
No-CY14B101NA is fixed as 64 K × 16 (16-bit bus), while CY14B101LA is the ×8 variant (128 K × 8). The -ZS45XIT suffix confirms TSOP II packaging and 45 ns speed grade, and its pinout includes BHE/BLE but omits A16, confirming exclusive ×16 organization.
Can HSB be used as an input-only pin to initiate STORE without monitoring its status?
Yes-HSB functions as an open-drain input to trigger hardware STORE when pulled LOW externally. However, monitoring HSB as an output (driven LOW during STORE) is required to prevent premature writes or reads during the STORE cycle, which would corrupt data or cause bus contention.
Is the 45 ns access time guaranteed over the full industrial temperature range?
Yes-the 45 ns tAA (address access time) is specified across –40°C to +85°C and 3.0 V ±10%, verified per JEDEC JESD22-A108 stress testing. This guarantee includes worst-case process corner, voltage, and temperature conditions, making it suitable for real-time deterministic systems.
