Product details
Overview
CY15V108QI-20BFXIT from Infineon is an 8-Mbit serial ferroelectric RAM (F-RAM) organized as 1024K × 8, operating on SPI interface at up to 20 MHz, with 1.71–1.89 V supply, industrial temperature range (–40°C to +85°C), and 10¹⁵ write endurance - deployed in real-time data logging systems requiring instant nonvolatile writes without delay.
For engineers reviewing the CY15V108QI-20BFXIT datasheet, CY15V108QI-20BFXIT pinout, CY15V108QI-20BFXIT application, or CY15V108QI-20BFXIT equivalent, this F-RAM delivers deterministic write latency, zero polling overhead, 151-year data retention, and hardware/software write protection - critical for high-cycle telemetry, industrial control registers, and power-fail-safe sensor buffers.
Technical Context
The CY15V108QI-20BFXIT implements a true SPI slave interface supporting modes 0 and 3, with opcode-driven command protocol including read, write, status register access, and special sector operations. Its internal architecture eliminates erase-before-write and page-programming constraints inherent to flash/EEPROM.
It integrates dedicated 256-byte special sector F-RAM tolerant to three reflow cycles, a 8-byte programmable serial number register, and Device ID/Manufacturer ID read-only identification - all accessible via standard SPI opcodes without address extension or timing penalties.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 8 Mbit (1024K × 8); supports byte-level random writes without block erase. |
| SPI clock frequency | Up to 20 MHz; enables 2.5 MB/s sustained write throughput with no wait states. |
| Write endurance | 10¹⁵ read/write cycles; eliminates wear leveling firmware and extends field lifetime beyond 20 years in high-frequency logging. |
| Data retention | 151 years at +85°C; guarantees nonvolatile storage integrity without refresh or backup power. |
| Supply voltage | 1.71 V to 1.89 V; compatible with 1.8 V logic domains and low-power SoC interfaces. |
| Operating temperature | –40°C to +85°C; qualified for industrial control, automotive body electronics, and outdoor metering. |
| Deep power-down current | 0.90 µA (typ); enables battery-backed operation for >10 years on coin cell in sleep mode. |
Pinout & Package
Package: 8-pin ultra-thin fine-pitch land grid array (UFLGA), 2.0 mm × 2.5 mm × 0.5 mm, RoHS-compliant, NRND status.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select input | Active-low enable; places device in standby (3.5 µA) when HIGH; initiates SPI transaction on falling edge. |
| SCK | Serial clock input | Synchronizes all I/O; rising edge samples SI, falling edge drives SO; supports 0–20 MHz with interruptible clock. |
| SI | Serial input | Accepts opcodes, addresses, and data; must be driven to valid logic level to meet IDD specs; may share pin with SO in single-line mode. |
| SO | Serial output | Drives read data on falling SCK edge; tristated during non-read cycles; supports standard SPI full-duplex or half-duplex. |
| WP | Write protect input | Hardware lock for Status Register when WPEN = 1; prevents accidental configuration changes; must tie to VDD if unused. |
| VSS | Ground | Reference return path for all digital and analog circuitry; requires low-impedance PCB connection. |
| VDD | Power supply | 1.71–1.89 V input; includes internal inrush current control to limit peak startup surge. |
| DNU | Do-not-use terminal | No internal connection; must remain floating or tied to VDD; not electrically bonded in die assembly. |
Key Features
| Feature | Design Value |
|---|---|
| Instant nonvolatile write | Writes complete at bus speed - no delay, no polling, no timeout handling required in host firmware. |
| Dedicated special sector | 256-byte F-RAM region survives ≥3 reflow cycles - ideal for storing calibration data or board IDs pre-assembly. |
| Multi-layer write protection | Combines hardware (WP pin), software (WRDI), and block-level (1/4, 1/2, full array) locks - prevents unintended overwrites in fielded systems. |
| Unique device identification | Factory-programmed 64-bit unique ID + 8-byte user-writable serial number - enables secure device authentication and traceability. |
| Inrush current control | Internal circuitry limits peak startup current - avoids brown-out in power-constrained systems with multiple F-RAMs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar nonvolatile serial memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY15B108QI-20BFXIT | Wider VDD range (1.8–3.6 V); lacks inrush current control; same pinout and SPI command set. | Suitable for mixed-voltage systems but less optimal for strict 1.8 V rail designs with tight inrush budgets. | Select when system operates above 1.89 V or requires broader supply flexibility. |
| MB85RS8MT-FPN-GE1 | Fujitsu 8-Mbit F-RAM; 20 MHz SPI; 1.8–3.6 V; no special sector or unique ID; different pinout (SO/IO shared). | Requires PCB redesign; lacks reflow-tolerant sector and device serialization - limits traceability in regulated markets. | Choose only if Infineon supply constraints exist and serial number/ID features are nonessential. |
Compared with CY15B108QI-20BFXIT and MB85RS8MT-FPN-GE1, the CY15V108QI-20BFXIT uniquely combines 1.8 V optimization, inrush control, reflow-hardened special sector, and factory-unique ID - making it the only choice for compact, safety-critical, long-lifecycle 1.8 V embedded systems.

FAQ
Is CY15V108QI-20BFXIT pin-compatible with CY15B108QI-20BFXIT?
Yes - both use identical 8-pin UFLGA packaging and share identical pin functions, signal timing, and SPI command structure. The only electrical differences are VDD range (1.71–1.89 V vs. 1.8–3.6 V) and presence of inrush current control, which does not affect pin behavior or layout.
Does the special sector survive reflow soldering more than three times?
No - the datasheet specifies survival through up to three standard reflow cycles (J-STD-020 profile). Beyond that, ferroelectric polarization stability is not characterized; for post-assembly programming, use the main array or external secure provisioning.
Can the serial number be overwritten after initial programming?
Yes - the 8-byte serial number register is user-writable via SPI command 0x1B (WRITE SERIAL NUMBER), subject to software write enable and status register protection settings. It retains data across power cycles and supports unlimited rewrites.
What happens if the WP pin is left floating?
Leaving WP floating violates the datasheet requirement. It must be tied to VDD if unused; otherwise, noise-induced LOW transitions can inadvertently lock the Status Register, preventing future configuration changes until power cycle and WRDI execution.
