Product details
Overview
CY15E016J-SXA from Cypress Semiconductor is a 16-Kbit (2K × 8) automotive-grade serial F-RAM with I²C interface, operating at up to 1 MHz, −40 °C to +85 °C, and 4.5–5.5 V supply. It delivers NoDelay™ writes, 10¹⁴ read/write endurance, and 151-year data retention-enabling reliable nonvolatile storage in real-time logging and control systems.
For engineers reviewing the CY15E016J-SXA datasheet, CY15E016J-SXA pinout, CY15E016J-SXA application, or CY15E016J-SXA equivalent, key selection criteria include write-speed-critical embedded logging, automotive-A temperature compliance, I²C bus timing compatibility, and hardware drop-in replacement capability for legacy serial EEPROMs.
Technical Context
The CY15E016J-SXA implements a ferroelectric memory array organized as 2,048 × 8 bits, accessed via standard I²C protocol with 7-bit slave address (1010xxxR/W) and 11-bit internal addressing (8-bit row + 3-bit segment). It requires no internal charge pump or write-cycle delay logic.
All write operations complete within one I²C byte transfer time-no polling, no wait states, and no voltage elevation. The device supports legacy I²C timings (100 kHz/400 kHz) and full-speed 1 MHz operation while maintaining strict automotive-A qualification per AEC-Q100.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16 Kbit (2,048 × 8), enabling compact firmware parameter storage without page management overhead |
| I²C Speed | Up to 1 MHz-supports high-throughput sensor data capture without bus arbitration bottlenecks |
| Write Endurance | 100 trillion (10¹⁴) cycles-eliminates wear-leveling firmware and enables sub-millisecond logging intervals |
| Data Retention | 151 years at +85 °C-guarantees long-term calibration data integrity in unpowered automotive modules |
| Operating Voltage | 4.5 V to 5.5 V-matches standard 5 V automotive microcontroller I/O rails without level-shifting |
| Temperature Range | −40 °C to +85 °C (Automotive-A)-qualified for under-hood and body-control module environments |
| Active Current | 100 µA at 100 kHz-minimizes power budget impact during frequent status updates |
Pinout & Package
8-pin SOIC (Small Outline Integrated Circuit) package, RoHS-compliant, surface-mountable with standard reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: WP | Write Protect input | Hardware-enables full-memory lock when pulled to VDD; internally pulled down for default write-enable |
| 2: SCL | I²C clock input | Master-generated synchronous edge (rising for sampling, falling for output) controlling all transfers |
| 3: SDA | I²C bidirectional data line | Open-drain, Schmitt-triggered, slope-controlled-requires external pull-up; supports multi-slave bus sharing |
| 4: NC | No-connect terminal | Die pad not bonded; must remain unconnected to avoid parasitic coupling or ESD path disruption |
| 5: VSS | Ground reference | Primary return path for all internal logic and I/O; must be low-impedance connection to system ground plane |
| 6: NC | No-connect terminal | Die pad not bonded; electrically isolated-no routing or soldering required |
| 7: VDD | Power supply input | Supplies core logic and I/O buffers; requires local 100 nF ceramic decoupling within 5 mm |
| 8: NC | No-connect terminal | Die pad not bonded; left floating per design-no PCB trace or thermal pad connection needed |
Key Features
| Feature | Design Value |
|---|---|
| NoDelay™ Write Architecture | Eliminates write latency and polling loops-data commits at I²C bus speed, enabling deterministic 100 µs worst-case write completion |
| Ferroelectric Memory Core | Provides true RAM-like write behavior with nonvolatile retention-no separate erase phase or write-protection registers required |
| Automotive-A Qualification | Validated per AEC-Q100 Rev G for temperature cycling, HTOL, and ESD-suitable for direct integration into ASIL-B supporting subsystems |
| I²C Bus Compatibility | Direct hardware replacement for 2K×8 EEPROMs (e.g., AT24C16) with identical pinout, timing, and address mapping-no firmware changes needed |
| Low-Power Write Operation | Draws only active-current-level power during writes-no elevated voltage generation reduces system-level power supply stress and noise |
Applications

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; requires 5 ms write cycle; 1 million endurance; no automotive qualification | Limited to consumer/industrial use; unsuitable for under-hood or safety-critical logging | Select only if cost sensitivity outweighs write speed, endurance, and temperature requirements |
| FM24V10-G (Cypress) | 1-Mbit F-RAM; 2.7–3.6 V operation; SPI interface; same endurance/retention specs | Requires voltage translation and interface redesign; higher density but incompatible pinout and protocol | Choose when migrating to higher capacity or lower voltage systems-not a drop-in replacement |
Compared with AT24C16D-SSHM-T and FM24V10-G, the CY15E016J-SXA uniquely combines automotive-A qualification, 1 MHz I²C, and true zero-latency writes in an 8-pin SOIC footprint-making it the only option for drop-in EEPROM replacement in thermally demanding, high-write-rate automotive subsystems.

FAQ
Is CY15E016J-SXA pin-compatible with standard 2K×8 I²C EEPROMs like AT24C16?
Yes-CY15E016J-SXA uses identical 8-pin SOIC packaging and pin assignments (WP, SCL, SDA, VSS, VDD) as AT24C16-series EEPROMs. Its I²C slave address (1010xxxR/W) and timing parameters align with legacy EEPROM specifications, enabling direct hardware substitution without PCB redesign.
Does CY15E016J-SXA require external circuitry for write protection or bus termination?
Only a single external pull-up resistor per I²C line (typically 2.2–4.7 kΩ on SDA/SCL) is required. The WP pin functions as a hardware write-lock when tied to VDD; no additional logic or voltage translators are needed. Internal Schmitt triggers and slope control eliminate need for external filtering or slew-rate compensation.
How does the 151-year data retention specification apply in real-world automotive use?
This value is measured at +85 °C per JEDEC JESD22-A117 and extrapolated using Arrhenius modeling. At typical under-dash ambient temperatures (max +70 °C), projected retention exceeds 300 years-ensuring calibration data remains intact over full vehicle service life, including long-term storage without power.
Can CY15E016J-SXA operate reliably during cold-cranking voltage dips below 4.5 V?
No-its specified minimum VDD is 4.5 V. Below this threshold, internal logic may malfunction or write operations become unreliable. System designers must implement brown-out detection or hold-up capacitance to maintain VDD ≥4.5 V during cranking transients, as confirmed in DC Electrical Characteristics Table (Section 9).
