Product details
Overview
CY15B016J-SXE from Infineon Technologies (formerly Cypress) is a 16-Kbit (2K × 8) serial I²C ferroelectric RAM (F-RAM) optimized for automotive-grade nonvolatile data logging. It delivers NoDelay™ writes, 10¹³ read/write endurance, 121-year data retention at +125°C, operates from 3.0–3.6 V, and is AEC-Q100 Grade 1 qualified for use in engine control units, battery management systems, and ADAS sensor modules.
For engineers reviewing the CY15B016J-SXE datasheet, CY15B016J-SXE pinout, CY15B016J-SXE application, or CY15B016J-SXE equivalent, key selection criteria include write-speed-critical logging, high-cycle-count field deployment, automotive temperature compliance, and drop-in replacement feasibility versus I²C EEPROM in legacy designs.
Technical Context
The CY15B016J-SXE implements a true nonvolatile memory architecture using lead zirconate titanate (PZT) ferroelectric capacitors, enabling RAM-like random-access reads/writes without write latency or wear leveling. Its I²C interface supports 100 kHz, 400 kHz, and 1 MHz modes with full backward timing compatibility.
It features hardware write protection via the WP pin, no internal charge pump (eliminating EEPROM-style high-voltage generation), and an 11-bit internal address latch supporting sequential and random access across its 2K-byte space. The device lacks power management circuitry beyond POR, requiring strict VDD regulation per datasheet limits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 16 Kbit (2,048 × 8 bytes): sufficient for firmware parameter storage, calibration tables, or event logs in compact ECUs. |
| Interface | I²C (2-wire serial): enables minimal PCB footprint and direct integration with microcontrollers lacking SPI peripherals. |
| Max clock frequency | 1 MHz: supports sub-10 µs byte writes-no polling required-enabling real-time capture of transient vehicle events. |
| Endurance | 10¹³ cycles: allows >27,000 writes/second continuously for 10+ years-ideal for black-box recording or CAN message buffering. |
| Data retention | 121 years at +125°C: guarantees integrity over full automotive lifecycle without refresh or backup power. |
| Operating voltage | 3.0 V to 3.6 V: matches standard automotive 3.3 V rail tolerances without level-shifting components. |
| Temperature range | –40°C to +125°C (AEC-Q100 Grade 1): validated for under-hood and transmission control module environments. |
Pinout & Package
8-pin SOIC (Small Outline Integrated Circuit) package with 1.27 mm pitch, RoHS-compliant, surface-mountable. Pin 1 marked by notch or dot; top-side marking includes "CY15B016J" and date code.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (WP) | Write Protect input | Hardware-enables full-memory lock when pulled to VDD; internally pulled down-default state is write-enabled. |
| 2 (SCL) | I²C clock input | Master-generated synchronous edge (rising for sampling, falling for output); requires external pull-up. |
| 3 (SDA) | I²C bidirectional data | Open-drain bus line with Schmitt trigger input and slew-rate-controlled output; shared with other I²C slaves. |
| 4 (NC) | No-connect | Internally unconnected die pad-must be left floating or tied to ground per layout best practices. |
| 5 (VSS) | Ground reference | Primary return path for all internal logic and I/O; must be low-impedance connection to system GND plane. |
| 6 (NC) | No-connect | Internally unconnected die pad-no electrical function; avoid routing signals underneath. |
| 7 (VDD) | Power supply input | 3.0–3.6 V nominal; requires local 100 nF ceramic decoupling within 5 mm of pin. |
| 8 (NC) | No-connect | Internally unconnected die pad-no thermal or electrical role; may be used for mechanical anchoring only. |
Key Features
| Feature | Design Value |
|---|---|
| NoDelay™ write architecture | Eliminates write latency and polling loops-data commits immediately after I²C ACK, enabling deterministic timing-critical logging. |
| Ferroelectric memory cell | Uses PZT capacitor switching instead of floating-gate charge trapping-no degradation mechanism, enabling 10¹³ cycles. |
| Automotive-grade qualification | AEC-Q100 Grade 1 certification verified across temperature, humidity, vibration, and ESD stress-no derating needed for under-hood use. |
| I²C timing compatibility | Supports legacy 100 kHz and 400 kHz timings while adding 1 MHz mode-enables seamless upgrade from EEPROM without firmware changes. |
| Low-power write operation | 120 µA active current at 100 kHz and 20 µA standby-reduces system-level power budget vs. EEPROM's high-voltage pump current. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial nonvolatile memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C16D-SSHM-T (Microchip) | 16-Kbit I²C EEPROM; 1M write cycles; 40 µs typical write time; no NoDelay™ capability. | Limited to infrequent parameter storage; unsuitable for high-frequency logging or real-time event capture. | Select only if cost sensitivity outweighs endurance and latency requirements. |
| FM24V10-G (Cypress/Infineon) | 1-Mbit F-RAM; same NoDelay™ and endurance; wider VDD range (2.0–3.6 V); 8-lead TDFN package. | Higher density for extended log buffers; lower voltage support enables direct connection to 2.5 V MCUs. | Choose when >16 Kbit capacity or dual-voltage operation is required. |
Compared with AT24C16D-SSHM-T, CY15B016J-SXE eliminates write latency and extends endurance by 10 million×; versus FM24V10-G, it trades density and voltage flexibility for smaller footprint and optimized automotive qualification at identical 8-pin SOIC form factor.

FAQ
Is CY15B016J-SXE pin-compatible with standard I²C EEPROMs like AT24C16?
Yes-CY15B016J-SXE uses identical 8-pin SOIC packaging and I²C protocol framing, including slave address (0xA0/0xA1) and memory addressing. Hardware replacement requires no PCB changes, though firmware benefits from eliminating write polling loops due to NoDelay™ operation.
Does CY15B016J-SXE require external high-voltage circuitry for writes?
No-unlike EEPROM, CY15B016J-SXE performs writes using standard VDD (3.0–3.6 V) without internal charge pumps or elevated voltages. This eliminates associated power spikes, EMI, and reliability concerns inherent in EEPROM write operations.
What is the significance of "Automotive-E" temperature grading?
"Automotive-E" denotes qualification to AEC-Q100 Grade 1 standards (–40°C to +125°C ambient), with full characterization and screening across that range-including HTOL, TC, and ESD testing. It certifies suitability for under-hood and transmission-mounted electronic control units.
Can CY15B016J-SXE be used in non-automotive industrial applications?
Yes-its 121-year data retention at +125°C, 10¹³ endurance, and wide VDD range make it equally suitable for industrial PLCs, medical diagnostics equipment, and energy metering systems where long-term reliability and frequent writes are critical.
