Product details
Overview
CY14B101Q2A-SXIT from Infineon Technologies (formerly Cypress) is a 1-Mbit serial SPI nonvolatile SRAM (nvSRAM), organized as 128K × 8, featuring QuantumTrap nonvolatile storage, AutoStore on power-down, and 104 MHz fast-read capability. It operates from 2.7 V to 3.6 V, supports industrial temperature range (–40 °C to +85 °C), and uses an SOIC-16 package with VCAP and HSB pins for capacitor-backed STORE and hardware-triggered nonvolatile write.
For engineers reviewing the CY14B101Q2A-SXIT datasheet, CY14B101Q2A-SXIT pinout, CY14B101Q2A-SXIT application, or CY14B101Q2A-SXIT equivalent, key selection criteria include AutoStore capacitor support, HSB pin availability for hardware STORE/RECALL status indication, SPI mode 0/3 compatibility, 20-year data retention at 85 °C, and software/hardware STORE/RECALL control flexibility.
Technical Context
This nvSRAM integrates SRAM and QuantumTrap SONOS-based nonvolatile elements in each cell, enabling infinite SRAM read/write cycles while providing 1 million STORE endurance and 20-year data retention. STORE transfers data from SRAM to nonvolatile cells; RECALL restores it on power-up or via command.
The device implements dual-speed SPI: standard 40 MHz zero-cycle-delay READ/WRITE and 104 MHz FAST_READ using a dummy byte. It supports SPI modes 0 and 3, includes a dedicated HSB pin for real-time STORE/RECALL busy signaling, and requires external VCAP capacitance (typically 4.7 µF) for AutoStore functionality.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1 Mbit (128K × 8) - full byte-addressable SRAM array with integrated nonvolatile backup per cell |
| Interface | SPI slave, modes 0 and 3 - compatible with standard microcontroller SPI peripherals without mode translation |
| Max Clock Rate | 104 MHz (FAST_READ only); 40 MHz (READ/WRITE) - enables high-throughput logging without wait states |
| Data Retention | 20 years at +85 °C - ensures long-term data integrity in industrial environments without refresh |
| STORE Endurance | 1 million cycles to QuantumTrap - defines maximum nonvolatile write events before wear-out |
| Operating Voltage | 2.7 V to 3.6 V - matches common 3.3 V system rails and allows direct interface with LDOs or PMICs |
| Temperature Range | –40 °C to +85 °C - qualified for industrial-grade embedded control and telemetry applications |
Pinout & Package
Package: 16-pin Small Outline Integrated Circuit (SOIC), RoHS-compliant, body width 7.5 mm, standard JEDEC MS-012AC footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select input | Active-low enable; drives device into standby when high, reducing current to 150 µA |
| SCK | Serial clock input | Accepts up to 104 MHz clock for FAST_READ; latches SI on rising edge, drives SO on falling edge |
| SI | Serial input | Receives opcodes (READ, WRITE, STORE, RECALL, WRSR, etc.) and address/data bytes |
| SO | Serial output | Drives read data, status register bits, or serial number; supports tri-state during HOLD |
| HSB | Hardware STORE Busy I/O | Output: LOW during STORE/RECALL; Input: pulling LOW initiates Hardware STORE (no WP pin on this variant) |
| VCAP | AutoStore capacitor supply | Connects external 4.7 µF capacitor to sustain STORE during VCC dropout; must not be grounded |
| VSS | Ground | Reference return for all digital and analog circuitry; requires low-impedance PCB connection |
| VCC | Power supply | 2.7–3.6 V main supply; powers SRAM core, SPI logic, and QuantumTrap control circuitry |
Key Features
| Feature | Design Value |
|---|---|
| AutoStore with VCAP | Enables automatic nonvolatile save on power loss using a single external capacitor-no host intervention required |
| Hardware STORE via HSB | Allows deterministic, low-latency STORE initiation by asserting HSB pin, bypassing SPI latency and firmware overhead |
| 104 MHz FAST_READ | Delivers 13 MB/s sequential read throughput using dummy-byte protocol-ideal for burst telemetry capture |
| QuantumTrap technology | SONOS-based nonvolatile cell architecture delivering 20-year retention and 1M STORE cycles without wear leveling |
| Zero-cycle-delay writes | All SRAM writes execute at full SPI bus speed with no wait states-enables real-time data buffering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar nvSRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY14B101Q3A-SXIT | Includes HSB pin and VCAP; adds WP pin (absent on CY14B101Q2A); same memory size and voltage range | Supports hardware write protection in addition to HSB-triggered STORE-suitable where dual-layer protection is mandated | Select when both hardware STORE and hardware write lock are required simultaneously |
| FM25V01-G | F-RAM-based 1 Mbit SPI memory; unlimited endurance; no STORE/RECALL latency; 3.0–3.6 V operation | No AutoStore capacitor or HSB pin; data written directly to nonvolatile cell-eliminates STORE timing uncertainty | Select when deterministic zero-latency writes outweigh need for 20-year retention at 85 °C |
Compared with CY14B101Q3A-SXIT, CY14B101Q2A-SXIT omits the WP pin but retains identical AutoStore and HSB functionality-ideal for cost-sensitive designs where software write protection suffices. Versus FM25V01-G, it trades F-RAM's infinite endurance for superior high-temperature data retention and deterministic STORE/RECALL sequencing.

FAQ
What is the minimum VCAP capacitance required for reliable AutoStore operation?
The datasheet specifies a nominal 4.7 µF tantalum or ceramic capacitor on VCAP, rated ≥6.3 V. With typical 2.7 V operation and 100 µs STORE time, this provides sufficient energy to complete SRAM-to-QuantumTrap transfer during VCC dropout. Lower values risk incomplete STORE under worst-case voltage ramp rates.
Does CY14B101Q2A-SXIT support SPI mode 1 or mode 2?
No. This device supports only SPI modes 0 (CPOL=0, CPHA=0) and 3 (CPOL=1, CPHA=1), as confirmed in the Functional Description and AC Switching Characteristics sections of the official datasheet. Attempting mode 1 or 2 will result in misaligned sampling and corrupted transfers.
Can the HSB pin be used solely as an input for Hardware STORE without connecting external pull-up?
Yes. When used as an input to trigger Hardware STORE, HSB requires no external pull-up; internal weak pull-up activates only after STORE completion. During active STORE, the pin is driven LOW by internal logic-external circuitry must assert and hold LOW for ≥100 ns to initiate the operation.
Is the 8-byte serial number factory-programmed and permanently locked?
Yes. The 8-byte serial number is laser-trimmed at wafer test and stored in one-time-programmable (OTP) memory. It is readable via RDSN instruction and cannot be altered or erased-providing immutable device identification for traceability and anti-counterfeiting in regulated industries.
