Product details
Overview
CY15B102QM-50SWXI from Infineon is a 2 Mb serial ferroelectric RAM (F-RAM) organized as 256K × 8, operating over SPI at up to 50 MHz with 1.8–3.6 V supply, –40°C to +85°C industrial temperature range, and 10¹⁵ write endurance. It delivers instant nonvolatile writes without polling, enabling real-time data logging in power-constrained industrial controllers.
For engineers reviewing the CY15B102QM-50SWXI datasheet, CY15B102QM-50SWXI pinout, CY15B102QM-50SWXI application, or CY15B102QM-50SWXI equivalent, key selection criteria include SPI mode 0/3 compatibility, hardware WP pin behavior, 256-byte special sector reflow survivability, deep power-down current (0.70 µA), and Device ID/serial number register accessibility.
Technical Context
The CY15B102QM-50SWXI implements a synchronous SPI slave interface with zero-latency write execution-data commits immediately upon byte transfer completion, eliminating wait states and status polling. Its F-RAM core uses lead zirconate titanate (PZT) ferroelectric capacitors to achieve 151-year data retention and 10¹⁵ endurance without charge-pump circuitry or block erase cycles.
It integrates dedicated on-die logic for SPI opcode decoding, nonvolatile status register control, and dual protection schemes: hardware WP pin gating of Status Register writes and software-configurable block protection (1/4, 1/2, or full array). The 256-byte special sector supports up to three standard reflow cycles while retaining calibration or configuration data.

Pinout & Package
Package: 8-pin SOIC (Small Outline Integrated Circuit), 150 mil width, RoHS-compliant, moisture sensitivity level (MSL) 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select input | Active-low enable: drives device into standby (2.3 µA) when HIGH; initiates SPI transaction 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 | Receives opcodes, addresses, and write data; must be held valid during active CS to meet IDD specs |
| SO | Serial output | Drives read data and status bits; tristated except during read cycles; transitions on SCK falling edge |
| WP | Write protect input | Hardware gate: blocks Status Register writes when WPEN=1 and WP=LOW; must tie to VDD if unused |
| VSS | Ground | Reference return path for all internal circuits; requires low-impedance connection to system ground plane |
| VDD | Power supply | 1.8–3.6 V input; powers core logic, F-RAM array, and I/O buffers; bypass capacitor required per datasheet |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial nonvolatile memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY15B102QN-50ZSXI | Same die, 8-pin TSSOP package (3 × 4.4 mm); 50 MHz max clock; identical timing and command set | Better thermal dissipation and higher board density; requires different footprint and reflow profile | Select for space-constrained designs where SOIC footprint is unavailable or thermal performance is critical |
| FM25V02A-G | Cypress (now Infineon) 2 Mb F-RAM; 40 MHz max SPI; 2.7–3.6 V only; no special sector or serial number registers | Lacks reflow-survivable sector and unique ID; lower max clock limits burst logging bandwidth | Select when cost sensitivity outweighs need for 50 MHz speed or board-unique identification |

FAQ
Does CY15B102QM-50SWXI require external high-voltage programming pulses like EEPROM?
No. The CY15B102QM-50SWXI uses ferroelectric capacitor switching at standard VDD levels (1.8–3.6 V) for all write operations. It performs true byte-level writes at bus speed with no charge pumps, erase cycles, or high-voltage generators-eliminating the 5–20 ms write delays inherent in EEPROM and flash.
Can the DNU pin be used as a general-purpose I/O or left unconnected?
The DNU pin has no internal connection and must never be driven or loaded. Per Infineon's datasheet, it must either float (unconnected) or be tied to VDD. Using it as an I/O risks undefined behavior, increased leakage, or failure to meet AC timing specifications under temperature variation.
How does the 256-byte special sector survive three reflow cycles?
The special sector uses hardened ferroelectric material and optimized metallization that withstands repeated exposure to 260°C peak solder profiles without depolarization or intermetallic diffusion. Its contents remain intact post-reflow, enabling storage of board-unique calibration data that persists across manufacturing and field repair.
Is SPI mode 3 support mandatory for interfacing with an ARM Cortex-M4 MCU?
No. SPI mode 3 (CPOL=1, CPHA=1) is optional. The CY15B102QM-50SWXI supports both mode 0 (CPOL=0, CPHA=0) and mode 3. Most Cortex-M4 implementations default to mode 0; mode 3 is only required if the host MCU's SPI peripheral is hard-configured to that polarity/phase and cannot be reprogrammed.
