Product details
Overview
CY14V101PS-SF108XIT from Cypress Semiconductor is a 1-Mbit (128K × 8) Quad SPI nonvolatile SRAM with integrated real-time clock, operating at up to 108 MHz interface speed, supporting AutoStore via VCAP capacitor and hardware STORE/RECALL via HSB pin, and delivering 54 MBps read/write bandwidth for industrial data logging and power-fail-safe memory applications.
For engineers reviewing the CY14V101PS-SF108XIT datasheet, CY14V101PS-SF108XIT pinout, CY14V101PS-SF108XIT application, or CY14V101PS-SF108XIT equivalent, key selection considerations include QPI/DPI/SPI mode flexibility, RTC register access via RDRTC/WRRTC instructions, VRTCbat-backed timekeeping, and hardware STORE initiation via HSB pin assertion.
Technical Context
The device integrates SRAM and SONOS FLASH Quantum Trap nonvolatile cells in a unified 128K × 8 array, enabling infinite SRAM read/write cycles while guaranteeing 20-year data retention at 85 °C and one million STORE cycles to nonvolatile elements. It supports SPI modes 0 and 3 with configurable clock polarity and phase.
QPI operation enables 4-bit-per-cycle transfers using I/O0–I/O3 pins; dual and quad I/O modes require tri-stating unused I/O pins during CS assertion. RTC functionality includes programmable square wave output (1 Hz to 32.768 kHz), alarm, watchdog timer, and interrupt generation on INT/SQW pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 1 Mbit (128K × 8): Full SRAM-accessible memory space with parallel STORE/RECALL between volatile and nonvolatile layers. |
| Interface Speed | 108 MHz QPI: Enables 54 MBps throughput for burst-wrap reads/writes in quad mode, critical for high-speed data capture before power loss. |
| Data Retention | 20 years at 85 °C: Guaranteed nonvolatile data integrity without refresh, validated for industrial thermal environments. |
| STORE Endurance | 1 million cycles: Maximum supported hardware/software STORE operations to SONOS FLASH Quantum Trap cells. |
| Supply Voltages | VCC = 2.7–3.6 V (core); VCCQ = 1.71–2.0 V (I/O): Dual-rail operation isolates I/O signaling from core logic, reducing noise coupling. |
| RTC Backup | VRTCBAT pin: Dedicated battery input sustaining RTC registers and oscillator during main power failure, independent of VCAP function. |
| Power Modes | Sleep = 380 µA; Hibernate = 8 µA (both at 85 °C): Ultra-low quiescent current for extended battery-backed RTC operation. |
Pinout & Package
16-pin SOIC package with 300-mil body width, surface-mount compatible, JEDEC MS-012AC compliant. Pin 1 index marker located at top-left corner when viewed from top side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select Input | Active-low enable for SPI instruction decoding; HIGH places device in standby with reduced current draw. |
| SCK | Serial Clock Input | Drives all SPI timing; latches SI on rising edge, drives SO on falling edge; supports up to 108 MHz in QPI mode. |
| SI (I/O0) | Serial Input / I/O0 | Primary instruction/data input in SPI mode; becomes bidirectional I/O0 in DPI/QPI for command/address/data multiplexing. |
| SO (I/O1) | Serial Output / I/O1 | Primary data output in SPI mode; becomes bidirectional I/O1 in DPI/QPI for full-duplex transfer. |
| WP (I/O2) | Write Protect / I/O2 | Hardware write lock in SPI/DPI; reconfigured as I/O2 in QPI for quad-mode address/data transfer. |
| NC (I/O3) | No Connect / I/O3 | Floating in SPI/DPI; becomes active I/O3 in QPI for fourth data lane-must be tri-stated during CS assertion in dual/quad modes. |
| HSB | Hardware STORE Busy | Open-drain status output (LOW = busy); also accepts external LOW pulse to trigger hardware STORE independently of power state. |
| VCAP | AutoStore Capacitor | Connects external capacitor (typically 4.7–10 µF) to sustain STORE during VCC collapse; must not be grounded. |
| VRTCBAT | RTC Battery Supply | Dedicated backup rail for RTC oscillator and registers; operates independently of VCC and VCAP functions. |
| XIN/XOUT | RTC Crystal Interface | Connects 32.768 kHz tuning-fork crystal; XIN is input, XOUT is buffered output-both unconnected if RTC disabled. |
| INT/SQW | Interrupt/Square Wave | Programmable open-drain output for RTC alarms, watchdog timeout, or calibrated square wave (1 Hz–32.768 kHz). |
| VCC/VCCQ/VSS | Power/Ground Rails | VCC powers core logic; VCCQ powers I/O buffers (1.71–2.0 V only); VSS is common ground reference for both domains. |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI Interface | Supports single/dual/quad I/O modes with opcode-based command set, enabling flexible bandwidth scaling without changing PCB layout. |
| AutoStore with VCAP | Guarantees automatic STORE on power-down using external capacitor-no firmware intervention required for data integrity. |
| Hardware STORE/RECALL | HSB pin allows external microcontroller to initiate STORE or detect completion, enabling synchronized system-level power management. |
| Integrated RTC | Full-featured real-time clock with alarm, watchdog, calibration, and programmable SQW output-no external RTC IC needed. |
| Serial Number OTP | 8-byte customer-programmable one-time-write serial number stored in nonvolatile register, enabling device traceability and anti-counterfeiting. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar nonvolatile memory with RTC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FM24V10-G | F-RAM-based 1-Mbit memory; no STORE latency; RTC lacks alarm/watchdog; VRTCbat not supported. | No battery-backed RTC features; limited to basic timekeeping without interrupt-driven events. | Select when ultra-fast STORE/RECALL (<1 µs) is critical and RTC complexity is unnecessary. |
| RV-3032-C3 | Dedicated RTC IC with I²C interface; no integrated memory; requires external nvSRAM or FRAM for data storage. | Separate memory + RTC architecture increases BOM count, PCB area, and power domain coordination effort. | Select when highest RTC accuracy (<±2 ppm) and long-term aging compensation are required over integrated simplicity. |
Compared with FM24V10-G and RV-3032-C3, CY14V101PS-SF108XIT uniquely combines QPI bandwidth, hardware STORE control, and full-featured RTC in one SOIC package-reducing system-level design effort while maintaining industrial-grade reliability and data integrity.

FAQ
What is the role of the VCAP pin and what capacitor value is recommended?
The VCAP pin supplies hold-up energy to complete STORE during VCC collapse. A 4.7 µF to 10 µF tantalum or ceramic capacitor is recommended-value selected based on worst-case voltage droop and STORE time (typically 5–10 ms). VCAP must never connect to ground or VCC; floating is acceptable only if AutoStore is disabled.
Can the RTC operate without an external crystal?
No-the RTC requires a 32.768 kHz crystal connected between XIN and XOUT pins for accurate timekeeping. Internal RC oscillators are not provided; omitting the crystal disables all RTC functions including alarm, watchdog, and SQW output, though nvSRAM remains fully operational.
How does hardware STORE differ from AutoStore?
Hardware STORE is initiated by externally pulling HSB LOW, triggering immediate data transfer from SRAM to nonvolatile cells regardless of VCC state. AutoStore activates automatically only during VCC decay, using energy from the VCAP capacitor. Both use the same SONOS FLASH storage layer but differ in trigger mechanism and timing control.
Is the CY14V101PS-SF108XIT pin-compatible with earlier CY14V101P variants?
Yes-CY14V101PS-SF108XIT uses the same 16-pin SOIC footprint and pinout as CY14V101P-SP25XIT and CY14V101P-SP40XIT. Key differences are interface speed (108 MHz vs. 25/40 MHz) and internal QPI optimization; existing layouts support drop-in replacement with firmware updates for new opcodes and timing parameters.
