Product details
Overview
CY14B101LA-ZS20XI from Infineon Technologies (formerly Cypress) is a 1-Mbit nonvolatile SRAM (nvSRAM) with QuantumTrap technology, organized as 128 K × 8, 20 ns access time, single 3.0 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-controlled STORE/RECALL for data retention in mission-critical embedded systems.
For engineers reviewing the CY14B101LA-ZS20XI datasheet, CY14B101LA-ZS20XI pinout, CY14B101LA-ZS20XI application, or CY14B101LA-ZS20XI equivalent, key selection criteria include AutoStore timing compliance, VCAP capacitor sizing, HSB-driven hardware store sequencing, and ×8 bus interface compatibility with microcontrollers requiring persistent RAM without battery backup.
Technical Context
The device integrates standard SRAM array (1024 × 1024) with parallel QuantumTrap nonvolatile storage cells, enabling simultaneous STORE/RECALL across all memory locations. It uses internal voltage regulation to charge VCAP and triggers AutoStore when VCC drops below VSWITCH (2.7 V typical), ensuring deterministic data capture during brownout.
Control logic supports three STORE modes: AutoStore (power-loss triggered), Hardware STORE (HSB pin assertion), and Software STORE (address-based command sequence). RECALL occurs automatically at power-up or via software, with SRAM read/write inhibited during both operations to guarantee atomicity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (128 K × 8 configuration) |
| Access Time | 20 ns - guarantees sub-20 ns SRAM read latency compatible with 50 MHz bus timing |
| Supply Voltage | 3.0 V ±10% / +20% - operates across wide industrial rail without external regulator |
| Data Retention | 20 years - nonvolatile data persistence without refresh or power |
| STORE Endurance | 1 million cycles - limits field lifetime of frequent power-cycle applications |
| Operating Temperature | –40°C to +85°C - qualified for industrial control and automotive under-hood environments |
| VSWITCH | 2.7 V (typ) - precise brownout threshold for reliable AutoStore activation |
Pinout & Package
Packaged in 32-pin SOIC (ZS20XI suffix denotes 32-pin SOIC, 20 ns speed, industrial temp).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | Selects one of 131,072 bytes; A16 used only in ×8 mode |
| DQ0–DQ7 | Bidirectional Data I/O | 8-bit parallel data path; tristated when OE HIGH or during STORE/RECALL |
| CE, OE, WE | Chip/Output/Write Enable | Standard SRAM control trio; all active LOW; CE gating required for multi-chip systems |
| VCAP | AutoStore Capacitor Supply | Internal regulator charges external capacitor (4.7 µF typical); powers STORE during VCC collapse |
| HSB | Hardware STORE Busy | Open-drain status output (LOW = STORE in progress); also accepts external LOW pulse to initiate STORE |
| VSS / VCC | Ground / Power | Single-supply operation; VSS must be low-impedance return path for noise-sensitive nvSRAM core |

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 (40 MHz SPI), no VCAP capacitor, 1014 endurance, but 85 ns random read latency | Requires serial interface redesign; unsuitable for parallel-bus SRAM drop-in | Choose for ultra-high write endurance in low-bandwidth logging where latency is secondary |
| MB85RS1MT-FPN-GE1 | 1-Mbit FRAM (SPI), 30 MHz, 1014 cycles, but lacks AutoStore and requires external power-fail detection | No built-in power-loss handling; adds BOM cost and board space for supervisor IC | Prefer when system already includes dedicated reset supervisor and SPI interface is available |
Compared with FM24V10-G and MB85RS1MT-FPN-GE1, CY14B101LA-ZS20XI uniquely delivers parallel-SRAM timing, integrated AutoStore, and deterministic 20 ns access-making it optimal for legacy industrial designs needing seamless battery-free persistence without architecture changes.

FAQ
What capacitor value and type is required on the VCAP pin?
A 4.7 µF tantalum or low-ESR ceramic capacitor rated for ≥6.3 V must be placed directly at the VCAP pin with minimal trace length. The capacitor supplies energy for a single STORE operation during VCC collapse; undersizing causes incomplete STORE and data corruption. Datasheet specifies 4.7 µF minimum, with 10 µF recommended for margin in high-temperature or extended brownout scenarios.
Can CY14B101LA-ZS20XI be used as a direct replacement for standard SRAMs?
Yes, in ×8 mode with identical pinout and timing-but only if AutoStore is disabled via software sequence and VCAP is either omitted or tied to VCC through a 10 kΩ resistor. Without disabling AutoStore, uncontrolled STORE attempts occur at power-up/down, causing bus contention and potential data loss. Standard SRAM replacement requires explicit firmware control of STORE/RECALL and careful power sequencing.
How does HSB function during a Hardware STORE operation?
HSB is an open-drain bidirectional pin: when driven LOW externally, it initiates a STORE; during STORE execution, it is actively driven LOW by the device to signal busy status. After completion, it transitions HIGH via internal weak pull-up (100 µA typical), and remains HIGH until next STORE. External pull-up (10 kΩ to VCC) is recommended for noise immunity during idle periods.
Is the 20-year data retention guaranteed at maximum operating temperature?
Yes, the 20-year retention is specified over the full industrial temperature range (–40°C to +85°C), validated per JEDEC JESD22-A117 accelerated life testing. Retention is not extrapolated-it is measured at 85°C with statistical confidence, ensuring reliability in thermal-stressed environments like motor control cabinets or outdoor smart meters.
