Product details
Overview
CY15E016J-SXET from Infineon Technologies (formerly Cypress) is a 16-Kbit (2K × 8) serial I²C ferroelectric RAM (F-RAM) designed for automotive nonvolatile data logging and control. It delivers NoDelay™ writes, 10¹³ read/write endurance, 121-year data retention at +125°C, operates from 4.5 V to 5.5 V, and is AEC-Q100 Grade 1 qualified for –40°C to +125°C environments.
For engineers reviewing the CY15E016J-SXET datasheet, CY15E016J-SXET pinout, CY15E016J-SXET application, or CY15E016J-SXET equivalent, key selection criteria include write-speed-critical logging, high-cycle-count industrial telemetry, automotive ECU parameter storage, and drop-in I²C EEPROM replacement without firmware changes.
Technical Context
The CY15E016J-SXET implements a true nonvolatile memory core using lead zirconate titanate (PZT) ferroelectric capacitors, enabling RAM-like random-access reads/writes with no write latency or page programming overhead. Its I²C interface supports 100 kHz, 400 kHz, and 1 MHz modes with full backward timing compatibility.
It uses an 11-bit internal address space (8-bit row + 3-bit segment), requires no internal charge pump or write-cycle polling, and relies solely on external pull-up resistors on SDA/SCL - eliminating power-supply complexity seen in EEPROMs and flash-based serial memories.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 16 Kbit (2,048 × 8), enabling compact storage of calibration tables or event logs without external addressing logic |
| Interface | I²C (2-wire), directly replaces legacy serial EEPROMs without hardware or software redesign |
| Max clock frequency | 1 MHz, supporting real-time data capture at up to 100 ksamples/s with byte-level writes |
| Write endurance | 10¹³ cycles - sustains continuous 100-Hz logging for >3,170 years before wear-out |
| Data retention | 121 years at +125°C - guaranteed retention over full automotive E-life without refresh |
| Supply voltage | 4.5 V to 5.5 V - compatible with 5 V microcontroller I/O domains and legacy automotive power rails |

Pinout & Package
8-pin small outline integrated circuit (SOIC) package with standard 1.27 mm pitch, surface-mount footprint, and RoHS-compliant matte tin lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: WP | Write Protect input | Hardware-level lock for entire memory map; tied to VDD disables all writes, tied to GND enables full access |
| 2: SCL | I²C clock input | Master-generated synchronous edge-triggered clock; rising edge samples SDA, falling edge outputs data |
| 3: SDA | I²C bidirectional data line | Open-drain bus line with Schmitt trigger input and slope-controlled output; requires external pull-up |
| 4: NC | No connect | Internally unconnected die pad; must remain floating or grounded per PCB layout best practice |
| 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 | Internally unconnected die pad; must remain floating or grounded per PCB layout best practice |
| 7: VDD | Power supply input | Single 4.5–5.5 V rail powers all logic, memory array, and I/O; no auxiliary supplies required |
| 8: NC | No connect | Internally unconnected die pad; must remain floating or grounded per PCB layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| NoDelay™ write architecture | Eliminates write polling and timeout handling in firmware - data commits immediately after I²C ACK, enabling deterministic sub-μs write completion |
| Ferroelectric memory cell | Enables 10¹³ endurance and 121-year retention without oxide degradation mechanisms inherent to flash or EEPROM |
| I²C timing compatibility | Supports legacy 100 kHz and 400 kHz timings while adding 1 MHz mode - preserves interoperability across MCU generations |

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 built-in write protection pin | Limited to infrequent parameter updates; requires firmware polling and timeout handling | Select only if cost sensitivity outweighs write endurance and latency requirements |
| FM24V10-G (Cypress/Infineon) | 1-Mbit F-RAM; 3.0–3.6 V operation; SOIC-8; same NoDelay™ and endurance specs | Higher density but incompatible voltage range - not suitable for 5 V systems | Choose for 3.3 V designs needing >16 Kbit capacity without changing interface or timing |
Compared with AT24C16D-SSHM-T, CY15E016J-SXET eliminates write latency and extends endurance by 10 million×; versus FM24V10-G, it supports 5 V operation and AEC-Q100 Grade 1, making it the sole option for legacy 5 V automotive modules requiring drop-in EEPROM replacement.

FAQ
Is CY15E016J-SXET pin-compatible with standard 8-pin SOIC EEPROMs like AT24C16?
Yes - CY15E016J-SXET uses identical 8-pin SOIC packaging and I²C pin assignments (SCL, SDA, WP, VDD, VSS) with matching electrical drive strength and timing margins. No PCB redesign is needed for drop-in replacement of AT24C16-series EEPROMs in existing 5 V systems.
Does CY15E016J-SXET require external circuitry beyond pull-up resistors on SDA/SCL?
No - unlike EEPROMs requiring high-voltage charge pumps, CY15E016J-SXET operates from a single 4.5–5.5 V supply with only two external pull-up resistors (typically 2.2–10 kΩ). No decoupling capacitor is mandatory but recommended (100 nF ceramic near VDD pin) for noise immunity.
How does the WP pin function during power-up or brown-out conditions?
The WP pin has an internal pull-down resistor (~100 kΩ), ensuring write-enable state (WP = LOW) at power-on reset. If external WP is tied to VDD, write protection engages only after VDD stabilizes above 4.5 V - preventing spurious locks during power ramp-up or dips.
Can CY15E016J-SXET be used in systems with mixed 3.3 V and 5 V I/O domains?
No - CY15E016J-SXET is strictly a 5 V device (4.5–5.5 V VDD). Its I²C pins are not 5 V tolerant when operated from 3.3 V supplies. For mixed-voltage systems, level-shifting circuitry or selection of the 3.3 V FM24V10-G variant is required.
