Product details
Overview
FM24CL16B-G from Cypress Semiconductor is a 16-Kbit (2K × 8) serial I²C ferroelectric RAM (F-RAM) nonvolatile memory with NoDelay™ write capability, 10¹⁴ read/write endurance, and 151-year data retention at +85 °C. It operates from 2.7 V to 3.65 V across –40 °C to +85 °C and serves as a hardware-compatible drop-in replacement for I²C EEPROM in data-logging and industrial control systems.
For engineers reviewing the FM24CL16B-G datasheet, FM24CL16B-G pinout, FM24CL16B-G application, or FM24CL16B-G equivalent, key selection criteria include write-speed-critical nonvolatile storage, high-cycle-count logging, low-power I²C bus integration, and industrial-temperature EEPROM replacement without firmware or timing changes.
Technical Context
The FM24CL16B-G implements an I²C slave interface with fixed 7-bit address prefix 1010b and programmable 3-bit page select, supporting standard-mode (100 kHz), fast-mode (400 kHz), and fast-mode plus (1 MHz) timing. Its internal 11-bit address latch enables full 2K-byte addressing via combined page + word address.
F-RAM core architecture eliminates write latency: each byte is committed immediately upon successful I²C ACK, requiring no polling or delay cycles. Unlike EEPROM, it avoids charge-pump circuitry-hence no elevated VPP, lower active current (100 µA @ 100 kHz), and no wear-out mechanism tied to voltage stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 16 Kbit (2,048 × 8 bits); supports sequential and random access without erase cycles |
| Interface | I²C-compatible 2-wire bus; direct hardware replacement for serial EEPROM with same pinout and protocol |
| Write endurance | 100 trillion (10¹⁴) read/write cycles; enables >100 years of daily 1000-write logging at full rate |
| Data retention | 151 years at +85 °C; guaranteed nonvolatile storage without refresh or backup power |
| Operating voltage | 2.7 V to 3.65 V; compatible with 3.3 V logic systems and industrial supply rails |
| Temperature range | –40 °C to +85 °C; qualified for industrial control, metering, and automotive body electronics |
| Write speed | NoDelay™ writes: byte written at bus speed; next I²C transaction starts immediately after ACK-no polling required |
Pinout & Package
FM24CL16B-G is available in two RoHS-compliant packages: 8-pin SOIC (3.9 mm × 4.9 mm) and 8-pin DFN (2 mm × 3 mm) with exposed pad (non-connected). Both share identical pin functions and I/O mapping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SDA | Bi-directional I²C data line | Open-drain I/O with Schmitt trigger input and slope-controlled output; requires external pull-up resistor |
| SCL | Input-only I²C clock line | Drives internal timing; data sampled on rising edge, output shifted on falling edge |
| WP | Hardware write-protect control | Logic HIGH (VDD) locks entire memory map; LOW enables all writes; internally pulled down |
| VSS | Ground reference | System ground connection; must be low-impedance path for noise immunity and stable operation |
| VDD | Power supply input | Supplies core logic and F-RAM array; no internal voltage regulation-must stay within 2.7–3.65 V |
| NC | No-connect die pads | Unbonded pins; electrically isolated-no routing or termination required |
Key Features
| Feature | Design Value |
|---|---|
| NoDelay™ write architecture | Eliminates write polling and timeout handling in firmware-reduces CPU overhead and system latency |
| 10¹⁴ endurance rating | Supports continuous high-frequency logging (e.g., sensor sampling every 10 ms) for >30 years without degradation |
| 151-year data retention | Enables long-term unpowered storage in battery-backed or energy-harvesting systems without refresh circuitry |
| I²C bus speed support up to 1 MHz | Reduces memory transaction time by 10× vs. 100 kHz EEPROM-critical for real-time data capture |
| Low active current (100 µA @ 100 kHz) | Minimizes power budget impact in always-on industrial nodes and portable instrumentation |

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; 10 ms typical write time; requires polling | Limited to infrequent configuration storage-not suitable for high-rate logging or real-time commit | Select only when cost sensitivity outweighs write performance and endurance requirements |
| MB85RC16 (Fujitsu) | 16-Kbit I²C F-RAM; same 10¹⁴ endurance and NoDelay writes; 2.7–5.5 V operation | Broadens supply compatibility but lacks WP pin-requires software-based protection | Prefer when wider voltage range is needed and hardware write protect is not mandatory |
Compared with AT24C16D-SSHM-T, FM24CL16B-G delivers 100 million× higher endurance and eliminates write latency; versus MB85RC16, it adds hardware write protection and tighter voltage tolerance optimized for 3.3 V industrial systems.

FAQ
Is FM24CL16B-G pin-compatible with standard 8-pin I²C EEPROMs like AT24C16?
Yes-FM24CL16B-G uses identical 8-pin SOIC and DFN footprints and matches the I²C slave address structure (1010xxxR/W), enabling direct PCB-level replacement without layout changes. The WP, SDA, SCL, VDD, and VSS pin assignments are functionally and physically aligned with industry-standard serial EEPROMs.
Does FM24CL16B-G require special I²C timing or firmware modifications?
No-FM24CL16B-G supports standard I²C timing modes (100 kHz, 400 kHz, and 1 MHz) and behaves identically to EEPROM during START/STOP, ACK/NACK, and address/data transfer sequences. Firmware retains full compatibility; only polling loops can be removed due to NoDelay™ writes.
What is the role of the EXPOSED PAD in the DFN package?
The EXPOSED PAD on the 8-pin DFN variant is electrically unconnected to the die and must not be soldered to the PCB ground plane. It serves only as a mechanical thermal relief feature and has no electrical function-leaving it floating or omitting solder paste prevents unintended shorting or signal coupling.
How does FM24CL16B-G handle power loss during a write operation?
Because writes complete at I²C bus speed (within one byte transfer time), FM24CL16B-G guarantees atomic byte writes: if power fails mid-transfer, only the incomplete byte is lost-no corruption of prior or adjacent memory locations occurs. This eliminates the need for EEPROM-style page-write buffers or wear-leveling firmware.
