Product details
Overview
CY15B102QN-50LHXIT from Infineon is a 2 Mb serial ferroelectric RAM (F-RAM) organized as 256K × 8, operating over SPI at up to 50 MHz with 1.8 V–3.6 V supply, 10¹⁵ write endurance, and 151-year data retention. It serves as a nonvolatile memory replacement for EEPROM/flash in high-write-cycle industrial data logging and control systems.
For engineers reviewing the CY15B102QN-50LHXIT datasheet, CY15B102QN-50LHXIT pinout, CY15B102QN-50LHXIT application, or CY15B102QN-50LHXIT equivalent, key selection criteria include SPI mode 0/3 compatibility, hardware/software write protection, deep power-down current (0.1 µA), dedicated 256-byte special sector, and industrial temperature range (–40°C to +85°C).
Technical Context
The CY15B102QN-50LHXIT implements an SPI slave interface with zero-latency writes-no polling required-and supports full-speed read/write at bus clock rates up to 50 MHz. Its ferroelectric memory array eliminates erase cycles and enables byte-level random access without page constraints.
It integrates a nonvolatile status register, device ID (manufacturer + product ID), unique ID, and 8-byte writable serial number. The dedicated 256-byte special sector survives up to three reflow soldering cycles, enabling board-level traceability and calibration storage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 2 Mb (256K × 8 bits); supports byte-addressable random access without erase overhead |
| SPI max frequency | 50 MHz; enables sub-microsecond write latency per byte, eliminating system wait states |
| Data retention | 151 years at +85°C; guaranteed nonvolatile storage without refresh or backup power |
| Write endurance | 10¹⁵ cycles; supports continuous logging at 1 kHz for >31,700 years without wear-out |
| Supply voltage | 1.8 V to 3.6 V; compatible with 1.8 V, 2.5 V, 3.3 V logic domains without level shifters |
| Deep power-down current | 0.1 µA typical; enables ultra-low-energy operation in battery-backed or energy-harvested systems |
| Operating temperature | –40°C to +85°C; qualified for industrial control, metering, and factory automation environments |
Pinout & Package
Package: 8-pin SOIC (Small Outline Integrated Circuit), RoHS-compliant, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select input | Active-low enable; places device in standby (2.3 µA) when HIGH; initiates all SPI transactions on falling edge |
| SCK | Serial clock input | Synchronizes all I/O; rising edge samples SI, falling edge drives SO; supports 0–50 MHz with interruptible clock |
| SI | Serial input | Accepts opcodes, addresses, and write data; must be driven to valid logic level to meet IDD specs |
| SO | Serial output | Drives read data during read cycles only; tristated otherwise; transitions on SCK falling edge |
| WP | Write protect input | Hardware lock for status register when WPEN = 1; must tie to VDD if unused to prevent accidental lockout |
| VSS | Ground | System reference return path; requires low-impedance connection to PCB ground plane |
| VDD | Power supply | 1.8–3.6 V core supply; decoupling capacitor (0.1 µF) required within 10 mm of pin |
| DNU | Do-not-use | No internal connection; leave floating or tie to VDD-never connect to signal or ground |
Key Features
| Feature | Design Value |
|---|---|
| Virtually unlimited write endurance | 10¹⁵ cycles enables lifetime data logging in smart sensors without wear leveling firmware |
| Instant nonvolatile write | No write delay or polling; next SPI transaction starts immediately after byte transfer completes |
| Dedicated 256-byte special sector | Survives ≥3 reflow cycles; stores board-specific calibration, MAC address, or firmware version |
| Multi-layer write protection | Combines hardware (WP pin), software (WRDI), and block-level (1/4, 1/2, full array) locking |
| Device identification | Read-only Device ID + Unique ID + writable 8-byte serial number for traceability and anti-counterfeiting |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial nonvolatile memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY15B102QN-40LAXI | 40 MHz max SPI speed (vs. 50 MHz); same package, voltage, endurance, and retention | Limited bandwidth for high-throughput logging; suitable where <20 MB/s throughput suffices | Select when system clock budget or EMI constraints require lower SCK frequency |
| FM25V02A-G | Cypress (now Infineon) 2 Mb F-RAM; 40 MHz, 2.0–3.6 V, SOIC-8; identical architecture but different status register map | Requires firmware adaptation for status bit interpretation and WP behavior | Choose for legacy design continuity where FM25V02A-G footprint and codebase already exist |
Compared with CY15B102QN-40LAXI, the -50LHXIT delivers 25% higher SPI bandwidth for time-critical logging; versus FM25V02A-G, it offers identical reliability but simplified migration via unified Infineon EXCELON™ LP register set and enhanced special sector robustness.

FAQ
Is CY15B102QN-50LHXIT pin-compatible with standard SPI EEPROMs or flash devices?
Yes-it uses industry-standard 8-pin SOIC with identical CS/SCK/SI/SO/WP/VSS/VDD pin assignments and SPI command set compatibility. No PCB redesign is needed for drop-in replacement of serial EEPROMs like AT25DF021 or flash devices such as W25Q20, though firmware must disable polling loops due to instant-write behavior.
Does the 256-byte special sector require separate addressing or commands?
Yes-the special sector is accessed using dedicated opcodes (0x77 for read, 0x76 for write) and occupies fixed addresses 0x00000–0x000FF. It operates independently from main array commands and retains data through ≥3 reflow cycles due to hardened ferroelectric cell design and thermal isolation.
How does write protection work when both WP pin and software lock are enabled?
Hardware WP takes precedence: when WP is LOW and WPEN=1 in the status register, all status register writes-including block protection bits-are blocked. Software WRDI instruction disables write enable latch globally, while block protection bits restrict writes to defined memory regions regardless of WP state.
Can CY15B102QN-50LHXIT operate reliably at 1.8 V while sustaining 50 MHz SPI?
Yes-datasheet Section 6 specifies full 50 MHz operation down to VDD = 1.8 V. At this voltage, active current is 2.4 mA (typ), and timing parameters including tSU, tH, and tV remain within spec. No derating or reduced functionality applies across the entire 1.8–3.6 V range.
