Product details
Overview
CY15V104QN20BFXITXUMA1 from Infineon is a 4-Mb serial ferroelectric RAM (F-RAM) organized as 512K × 8, operating on SPI interface at up to 50 MHz with 1.71–1.89 V supply, 10¹⁵ write endurance, and 151-year data retention. It serves as nonvolatile memory in real-time data logging systems where rapid, reliable byte-level writes eliminate flash/EEPROM latency and wear-out risks.
For engineers reviewing the CY15V104QN20BFXITXUMA1 datasheet, CY15V104QN20BFXITXUMA1 pinout, CY15V104QN20BFXITXUMA1 application, or CY15V104QN20BFXITXUMA1 equivalent, this F-RAM delivers deterministic zero-latency writes, industrial temperature support (–40°C to +85°C), hardware/software write protection, and dedicated 256-byte reflow-survivable sector for board identification and calibration storage.
Technical Context
The CY15V104QN20BFXITXUMA1 implements an SPI slave interface compliant with modes 0 (CPOL=0, CPHA=0) and 3 (CPOL=1, CPHA=1), supporting continuous read/write transfers without polling. Its internal architecture includes a 512K × 8 main F-RAM array, a separate 256-byte special sector, nonvolatile status register, Device ID/Unique ID registers, and serial number registers.
Write operations complete within one SPI bus cycle - no internal write delay or erase phase - enabled by ferroelectric capacitor switching instead of charge trapping. The device uses dedicated WP pin control and software-configurable block protection (1/4, 1/2, or full array), with DNU pin explicitly designated as unused and requiring floating or VDD tie.
Key Specifications

Pinout & Package
Package: 8-pin SOIC (Small Outline Integrated Circuit), 208-mil body width, surface-mount, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select input | Active-low enable; places device in standby (2.3 µA) when HIGH; required falling edge before each opcode |
| SCK | Serial clock input | Synchronizes all I/O; rising edge samples inputs, falling edge drives outputs; supports 0–50 MHz with interruptible clock |
| SI | Serial data input | Accepts opcodes, addresses, and write data; must be driven to valid logic level to meet IDD specs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar nonvolatile serial memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY15B104QN20BFXITXUMA1 | Wider VDD range (1.8–3.6 V); same density, timing, and F-RAM architecture | Supports mixed-voltage systems (e.g., 3.3 V MCU with 1.8 V peripherals); not suitable for strict 1.8 V-only designs | Select when system rail exceeds 1.89 V or requires backward compatibility with legacy 3.3 V interfaces |
| MB85RS4MT-Y25-PFGE1 | Fujitsu 4-Mb FRAM; 1.8–3.6 V; 40 MHz max SPI; no special sector or serial number registers | Lacks reflow-survivable sector and unique ID; limited write-protection granularity (full-array only) | Choose for cost-sensitive, lower-feature applications where board ID and advanced protection are unnecessary |
Compared with CY15B104QN20BFXITXUMA1 and MB85RS4MT-Y25-PFGE1, the CY15V104QN20BFXITXUMA1 uniquely combines ultra-narrow 1.71–1.89 V operation, dedicated reflow-hardened sector, and full hierarchical write protection - making it optimal for next-gen 1.8 V industrial edge nodes demanding guaranteed data integrity and traceability.

FAQ
Is CY15V104QN20BFXITXUMA1 pin-compatible with standard SPI EEPROM 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 AT25DF041 or flash devices such as W25Q40, though timing and protection behavior differ fundamentally due to F-RAM architecture.
Does the 256-byte special sector require special initialization or access commands?
Yes - it is accessed using dedicated opcodes (0x77 for read, 0x78 for write) distinct from main array commands. The sector is pre-qualified to survive three JEDEC J-STD-020 reflow cycles; no user initialization is required, but writes must observe 5 ms maximum pulse width and avoid concurrent main-array operations.
What happens if the WP pin is left unconnected?
If WP is left floating, the device may enter unintended write-protection states due to noise coupling, risking failure to update status register or memory. Infineon specifies that WP must be tied to VDD when unused - this disables hardware write protection and ensures predictable software-controlled operation per the datasheet's absolute maximum ratings.
Can the Unique ID be overwritten or reset by the user?
No - the 64-bit Unique ID is factory-programmed laser-fused ROM and is read-only. It cannot be altered, erased, or regenerated. Only the 8-byte serial number register is user-writable via instruction 0x1B; its contents persist across power cycles and reflows but are not cryptographically secured.
