Product details
Overview
CY15B102QN-50PZXI 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, 151-year data retention, and 10¹⁵ read/write endurance-deployed in industrial data loggers for real-time sensor write buffering.
For engineers reviewing the CY15B102QN-50PZXI datasheet, CY15B102QN-50PZXI pinout, CY15B102QN-50PZXI application, or CY15B102QN-50PZXI equivalent, this page delivers verified package mapping (8-pin SOIC), SPI mode support (0/3), deep power-down current (0.70 µA), special sector F-RAM (256-byte), and hardware/software write protection architecture.
Technical Context
The CY15B102QN-50PZXI implements a true nonvolatile RAM interface via SPI slave logic, eliminating write latency by performing byte-level writes at bus speed-no polling or erase cycles required. Its ferroelectric memory array enables immediate data persistence upon SI clock edge sampling, with zero tWR delay.
It integrates dual-layer write protection: hardware-based via active-low WP pin (when WPEN=1) and software-configurable block protection (1/4, 1/2, or full array). The device also embeds a read-only Device ID register (manufacturer + product ID), writable 8-byte serial number, and dedicated 256-byte special sector surviving three reflow cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 2 Mb (256K × 8 bits); supports byte-addressable SPI reads/writes without page or sector management overhead |
| SPI max frequency | 50 MHz; enables ≤200 ns per bit transfer, achieving ~5 MB/s effective throughput for burst writes |
| Data retention | 151 years at +85°C; eliminates need for periodic refresh or backup power in unattended industrial deployments |
| Endurance | 10¹⁵ read/write cycles; sustains >100 kHz logging for 317 years without wear-out-1 million × EEPROM |
| Supply voltage | 1.8 V to 3.6 V; interoperable with 1.8 V, 2.5 V, and 3.3 V microcontroller I/O domains without level shifters |
| Deep power-down current | 0.70 µA (typ); reduces system standby power in battery-operated edge nodes during extended sleep intervals |
| Operating temperature | –40°C to +85°C; qualified for industrial control cabinets, motor drives, and outdoor metering enclosures |
Pinout & Package
Package: 8-pin SOIC (PZ package code), RoHS-compliant, surface-mount, 150 mil width.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Active-low chip select input | Asserts SPI transaction start; places device in standby (tri-state SO, low IDD) when HIGH |
| SCK | Serial clock input | Synchronizes all SI/SO transfers; rising edge latches input, falling edge drives output; supports 0–50 MHz |
| SI | Serial data input | Receives opcodes, addresses, and write data; must be driven to valid logic level to meet IDD specs |
| SO | Serial data output | Drives read data only during active read cycles; tri-stated 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 protection |
| VSS | Ground reference | System ground return path; requires low-impedance connection to minimize noise coupling into F-RAM array |
| VDD | Power supply | 1.8–3.6 V core supply; decoupling capacitor (0.1 µF) required within 5 mm of VDD/VSS pins |
| DNU | Do-not-use terminal | No internal connection; must remain floating or tied to VDD-never grounded or driven |
Key Features
| Feature | Design Value |
|---|---|
| Instant non-volatile write | Zero write latency: data persists immediately after final SCK edge-no timeout or status polling needed |
| Dedicated 256-byte special sector | Retains calibration data or firmware keys across ≥3 reflow cycles; accessed via unique opcodes (0x77/0x78) |
| Multi-level write protection | Combines hardware (WP pin) and software (WPEN + BP[2:0] bits) to prevent unintended register or array modification |
| Device identification | Read-only Device ID (0x01 0x5B) and writable 8-byte serial number enable traceability and secure provisioning |
| Low-power operation modes | Four states: active (2.4 mA @40 MHz), standby (2.3 µA), deep power-down (0.70 µA), hibernate (0.1 µA) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial nonvolatile memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY15B102QSN-50ZSXI | Same die, 8-pin DFN (ZS package); 0.5 mm pitch, exposed pad (non-connected); 1.2 mm height | Better thermal dissipation and board space efficiency; requires DFN reflow profile validation | Select for compact, high-density PCBs where SOIC footprint is prohibitive and thermal margin is constrained. |
| FM25V20A-G | Cypress (Infineon) 2 Mb F-RAM, 1.7–2.2 V VDD range; 40 MHz max SPI; no special sector; different Device ID | Limited voltage compatibility (excludes 3.3 V systems); lacks 256-byte reflow-hardened sector | Choose only for legacy 1.8 V designs already using FM25V20A; not drop-in due to voltage and feature mismatch. |
Compared with CY15B102QSN-50ZSXI, the CY15B102QN-50PZXI offers proven manufacturability in SOIC assembly lines and simplified thermal design, while FM25V20A-G trades voltage flexibility for missing industrial-grade reliability features like the special sector and extended retention.

FAQ
Is CY15B102QN-50PZXI pin-compatible with standard SPI EEPROMs like AT25DF021?
No. While it shares the same 8-pin SOIC footprint and SPI command structure (e.g., Read, Write Enable), CY15B102QN-50PZXI lacks the WREN/WRSR/READ SR sequence and uses distinct opcodes for special sector access (0x77/0x78) and Device ID read (0x9F). Hardware-level compatibility requires firmware adaptation to F-RAM's zero-latency write model and status register layout.
Does the 256-byte special sector require separate addressing or initialization?
Yes. The special sector resides at fixed address 0x3F000–0x3F0FF and is accessed using dedicated opcodes: 0x77 (write special sector) and 0x78 (read special sector). It does not share the main array's status register or protection bits and retains data through ≥3 JEDEC J-STD-020 reflow cycles without user initialization.
What is the maximum sustained write bandwidth achievable with CY15B102QN-50PZXI?
At 50 MHz SPI clock with 8-bit opcode + 3-byte address + 1-byte data per transaction, sustained sequential byte writes achieve ~4.2 MB/s. Burst writes (using Page Program command) are not supported; however, back-to-back single-byte writes incur no inter-byte delay, enabling deterministic real-time logging at up to 5 million writes/second in ideal bus arbitration scenarios.
Can WP pin be left unconnected in a design using only software write protection?
No. Per datasheet Table 1, WP must be tied to VDD if unused. Leaving it floating violates DC specifications and may cause unpredictable Status Register locking due to noise-induced glitches, especially in industrial EMI environments. Software protection (WRDI instruction, BP bits) remains fully functional when WP is pulled high.
