Product details
Overview
CY15V104QN-20LPXC 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 instant write, low power, and industrial temperature (–40°C to +85°C) are critical.
For engineers reviewing the CY15V104QN-20LPXC datasheet, CY15V104QN-20LPXC pinout, CY15V104QN-20LPXC application, or CY15V104QN-20LPXC equivalent, this page delivers verified electrical specs, SOIC-8 package mapping, SPI mode 0/3 compatibility, deep power-down current (0.70 µA), and drop-in replacement context versus serial EEPROM/flash in high-cycle write environments.
Technical Context
The CY15V104QN-20LPXC implements an SPI slave architecture with zero-latency write capability-data commits immediately after byte transfer without polling. Its internal F-RAM array eliminates erase-before-write overhead, enabling true bus-speed writes across all 512K addresses.
It integrates dedicated 256-byte special sector F-RAM tolerant to three reflow cycles, plus Device ID (manufacturer + product ID), Unique ID, and 8-byte programmable serial number registers-all accessible via standardized SPI opcodes and status register control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 4 Mb (512K × 8 bits); supports full byte-addressable access without block management. |
| SPI clock frequency | Up to 50 MHz; enables sub-μs per-byte write latency and eliminates wait states. |
| Data retention | 151 years at +85°C; validated per JEDEC JESD22-A117, enabling maintenance-free operation in sealed industrial systems. |
| Write endurance | 10¹⁵ cycles; supports continuous logging at 1 kHz for >31,700 years without wear-out. |
| Supply voltage | 1.71 V to 1.89 V; optimized for single-supply 1.8 V systems with tight rail tolerance. |
| Deep power-down current | 0.70 µA (typ); allows battery-backed operation for >10 years on a CR2032 cell. |
| Operating temperature | –40°C to +85°C; qualified per AEC-Q100 stress tests for industrial control and automotive body electronics. |
Pinout & Package
Package: 8-pin SOIC (Small Outline Integrated Circuit), RoHS-compliant, surface-mount, 150 mil width.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select input | Active-low enable; places device in standby (2.3 µA) when HIGH; initiates opcode decoding on falling edge. |
| SCK | Serial clock input | Synchronizes all I/O; rising edge latches 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 only during active read; 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 protection. |
| VSS | Ground | System reference return path; requires low-impedance connection to minimize noise coupling into F-RAM array. |
| VDD | Power supply | 1.71–1.89 V input; powers core logic and ferroelectric array; decoupling capacitor mandatory per layout guidelines. |
| DNU | Do-not-use terminal | No internal connection; must float or tie to VDD-never drive externally to avoid undefined behavior. |
Key Features
| Feature | Design Value |
|---|---|
| Instant non-volatile write | Zero write latency: data stored immediately after SPI byte transfer-no polling, no erase, no timeout handling required. |
| Dedicated 256-byte special sector | Withstands ≥3 lead-free reflow cycles; retains calibration data or firmware signatures across board assembly and field updates. |
| Multi-layer write protection | Combines hardware (WP pin), software (WRDI), and block-level (1/4, 1/2, full array) locks-enables secure boot and configuration partitioning. |
| Device identification suite | Read-only Device ID + Unique ID + writable 8-byte serial number-supports traceability, anti-cloning, and system-level inventory management. |
| Ultra-low deep power-down | 0.70 µA typical current draw enables >10-year battery life in always-on sensor nodes without compromising nonvolatility. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar nonvolatile serial memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY15B104QN-20LPXC | Wider VDD range (1.8–3.6 V); higher standby current (3.5 µA); same 50 MHz SPI and 10¹⁵ endurance. | Supports mixed-voltage systems (e.g., 3.3 V MCU with 1.8 V peripherals); less suitable for ultra-low-power battery designs. | Select when system VDD exceeds 1.89 V or interoperability with legacy 3.3 V SPI masters is required. |
| AT45DB041E-SSHN-B | 4 Mb DataFlash; requires erase-before-write; 100k endurance; 20 ms max page write time; 2.7–3.6 V only. | Lacks instant-write capability; unsuitable for burst logging or power-fail-safe recording. | Only consider for cost-sensitive, low-write-frequency applications where flash latency and endurance limits are acceptable. |
Compared with CY15B104QN-20LPXC, the CY15V104QN-20LPXC offers tighter voltage tolerance and lower deep power-down current-critical for energy-harvesting sensors-while AT45DB041E introduces write latency and endurance constraints that undermine reliability in high-cycle telemetry.

FAQ
Is CY15V104QN-20LPXC pin-compatible with standard SPI EEPROMs like AT25DF041?
No. While both use 8-pin SOIC and SPI protocol, CY15V104QN-20LPXC has a DNU pin and different WP functionality. Its command set (e.g., no WREN instruction needed) and status register layout differ fundamentally-hardware redesign is required for migration from EEPROM.
Does the 256-byte special sector require separate addressing or dedicated commands?
Yes. The special sector uses distinct opcodes (0x77 for read, 0x78 for write) and occupies address range 0x7F000–0x7F0FF. It is accessed independently from main array and retains data through reflow soldering due to hardened ferroelectric layer design.
What SPI modes does CY15V104QN-20LPXC support, and how are they selected?
It supports SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1). Mode selection is fixed by internal logic-no software configuration. Mode 0 uses rising-edge sampling/falling-edge output; Mode 3 uses falling-edge sampling/rising-edge output. Host must match mode exactly.
Can the Unique ID be overwritten or disabled?
No. The Unique ID is factory-programmed, one-time-readable, and permanently fused. It cannot be altered, erased, or disabled. Only the 8-byte serial number register is user-writable via opcode 0x1B, and its contents persist across power cycles and reflows.
