Product details
Overview
CY15V108QN-20LPXIT from Infineon is an 8 Mb serial ferroelectric RAM (F-RAM) organized as 1024K × 8, operating on SPI interface at up to 40 MHz with 1.71–1.89 V supply. It delivers instant non-volatile writes, 10¹⁵ read/write endurance, and 151-year data retention. Used in industrial data loggers for high-frequency sensor sampling where flash/EEPROM write latency causes data loss.
For engineers reviewing the CY15V108QN-20LPXIT datasheet, CY15V108QN-20LPXIT pinout, CY15V108QN-20LPXIT application, or CY15V108QN-20LPXIT equivalent, this page provides verified pin functions, real-world timing behavior, SPI mode compatibility (0 and 3), low-power mode current values, and drop-in replacement guidance versus serial EEPROM and flash.
Technical Context
The CY15V108QN-20LPXIT implements a true SPI slave architecture with zero-write-latency operation: data commits immediately after byte transfer without polling. Its F-RAM core eliminates erase cycles and supports full 40 MHz bus-speed writes across all 1024K addresses.
It integrates dedicated 256-byte special sector F-RAM retaining data through three reflow cycles, plus non-volatile Device ID, Manufacturer ID, and user-writable 8-byte serial number registers - all accessible via standardized SPI opcodes defined in the instruction decoder logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 8 Mb (1024K × 8 bits); enables single-chip replacement of 1-MB serial flash in firmware/data logging designs. |
| Max SPI clock | 40 MHz; supports ≤25 ns cycle time, enabling 4 MB/s sustained write throughput without wait states. |
| Data retention | 151 years at +85°C; eliminates periodic refresh or backup power requirements in sealed industrial enclosures. |
| Endurance | 10¹⁵ read/write cycles; sustains 1000 writes/sec continuously for >31 years without wear-out failure. |
| Supply voltage | 1.71–1.89 V; matches LP DDR I/O domains and avoids level-shifting in 1.8 V microcontroller systems. |
| Deep power-down current | 0.90 µA (typ); allows battery-backed operation for >10 years on a CR2032 coin cell in remote monitoring nodes. |
| Operating temperature | –40°C to +85°C; qualified for deployment in motor drives, PLC I/O modules, and outdoor metering hardware. |
Pinout & Package
Package: 8-pin SOIC (3.9 mm × 4.9 mm, 1.27 mm pitch), RoHS-compliant, industrial-grade molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Active-low chip select input | Asserted LOW to enable SPI communication; HIGH places device in standby (3.5 µA), tristates SO. |
| SCK | Serial clock input | Rising edge latches SI; falling edge drives SO; supports 0–40 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. |
| SO | Serial data output | Drives read data on falling SCK edge; tristated during write/standby; supports shared SI/SO bus. |
| WP | Hardware write protect input | LOW disables status register writes when WPEN=1; must tie to VDD if unused to prevent accidental lockout. |
| VSS | Ground reference | System ground return; requires low-impedance connection to minimize noise coupling into F-RAM array. |
| VDD | Power supply | 1.71–1.89 V nominal; bypass with 100 nF ceramic capacitor placed ≤2 mm from pin per layout guidelines. |
| DNU | No-connect terminal | Not internally bonded; leave floating or tie to VDD - no electrical function or thermal role. |
Key Features
| Feature | Design Value |
|---|---|
| Instant non-volatile write | Zero latency: data written to memory array immediately after byte transfer - no polling or timeout handling required in firmware. |
| Dedicated 256-byte special sector | Retains calibration data or security keys across ≥3 reflow cycles - usable for factory-programmed board identity storage. |
| Multi-layer write protection | Combines hardware (WP pin), software (WRDI), and block-level (1/4, 1/2, full array) locks - prevents accidental overwrites in field-deployed units. |
| Unique device identification | Factory-programmed 64-bit unique ID + 8-byte user-writable serial number - enables secure device binding and traceability in IIoT deployments. |
| Low-voltage deep power-down | 0.90 µA at 1.71 V enables energy harvesting applications with intermittent power sources and multi-year battery life. |

Use Value: Unique ID + serial number enables per-transducer audit trail; 0.1 µA hibernate current extends battery runtime between clinical sessions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar serial non-volatile memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY15B108QN-20LPXIT | Wider VDD range (1.8–3.6 V); higher standby current (5 µA); same 40 MHz SPI, 10¹⁵ endurance, and pinout. | Preferred in mixed-voltage systems (e.g., 3.3 V MCU with 1.8 V peripherals) where voltage flexibility outweighs ultra-low-power needs. | Select when system VDD varies or shares rail with 3.3 V logic; not suitable for sub-1.8 V operation. |
| AT45DB081E-SSHN-B | 8 Mb DataFlash; 55 MHz max clock; requires erase-before-write; 100k endurance; 20-year retention; 2.7–3.6 V only. | Used where cost-per-bit is primary and write frequency <100×/day; requires firmware erase management and polling. | Choose only if legacy flash interface compatibility is mandatory and write endurance is not critical. |
Compared with CY15B108QN-20LPXIT, the CY15V108QN-20LPXIT offers tighter voltage control and lower deep-power-down current, while AT45DB081E demands erase cycles and delivers far lower endurance - making CY15V108QN optimal for high-write, battery-constrained industrial nodes.

FAQ
Is CY15V108QN-20LPXIT pin-compatible with standard 8-pin SOIC SPI memories like AT25DF081?
Yes - it uses identical 8-pin SOIC footprint and SPI signal mapping (CS, SCK, SI, SO, WP, VSS, VDD, DNU). However, AT25DF081 is a flash device requiring erase cycles and polling; CY15V108QN executes writes at bus speed with no timing overhead or firmware changes needed beyond driver initialization.
Does the 256-byte special sector require separate addressing or commands?
Yes - it uses dedicated opcodes (0x77 for write, 0x78 for read) and occupies address range 0xFFFC00–0xFFFCFF. This sector is physically isolated and retains data through reflow soldering, unlike main array which is subject to thermal stress limits per JEDEC J-STD-020.
Can WP pin be left unconnected in designs where write protection is managed solely in software?
No - the datasheet mandates tying WP to VDD if unused. Leaving it floating risks metastability, unintended status register lockout, or increased leakage current. Software protection (WRDI) remains fully functional when WP is pulled high.
What is the maximum achievable sustained write throughput using standard SPI commands?
At 40 MHz with continuous page writes (256-byte pages), sustained throughput reaches 3.8 MB/s. This assumes no inter-byte gaps and full-duplex operation - verified by Infineon's AC switching characteristics (tW = 25 ns min, tSH = 10 ns min per byte).
