Product details
Overview
FM24CL16B-GTR from Cypress Semiconductor is a 16-Kbit (2K × 8) serial I²C 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 drop-in replacement for I²C EEPROM in real-time data logging and industrial control systems.
For engineers reviewing the FM24CL16B-GTR datasheet, FM24CL16B-GTR pinout, FM24CL16B-GTR application, or FM24CL16B-GTR equivalent, key selection criteria include write-cycle speed without polling, ultra-high endurance under frequent updates, I²C timing compatibility (100 kHz/400 kHz/1 MHz), and industrial-grade voltage/temperature operation.
Technical Context
The FM24CL16B-GTR 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 word + 3-bit page). It requires no internal charge pump or write delay cycles - data commits immediately after byte transfer completion.
Its interface supports START/STOP conditions, ACK/NAK handshaking, and sequential/random read/write modes. The device lacks power management circuitry beyond POR, relying on stable VDD within specification; WP pin enables hardware write protection across the full memory map.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 16 Kbit (2,048 × 8 bytes); supports byte- and page-write operations up to full 256-byte page without delay |
| I²C clock frequency | Up to 1 MHz; maintains backward compatibility with legacy 100 kHz and 400 kHz timing requirements |
| Write endurance | 100 trillion (10¹⁴) cycles; eliminates wear-leveling firmware overhead required for EEPROM |
| Data retention | 151 years at +85 °C; ensures long-term integrity without refresh or backup power |
| Supply voltage | 2.7 V to 3.65 V; compatible with 3.3 V logic systems and avoids level-shifting in mixed-voltage designs |
| Operating temperature | –40 °C to +85 °C; qualified for industrial control, metering, and automotive body electronics |
| Active current | 100 µA at 100 kHz; reduces system power budget during frequent memory access |
Pinout & Package
FM24CL16B-GTR 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 packages share identical pin functions and I/O mapping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SDA | Bi-directional I²C data line | Open-drain output with Schmitt-trigger input; requires external pull-up; supports multi-master bus arbitration |
| SCL | Input-only I²C clock line | Controls timing of all data transfers; rising edge samples input, falling edge drives output |
| WP | Hardware write-protect input | Pulled low internally; tie to VDD to lock entire memory map; no software configuration needed |
| VSS | Ground reference | Must be connected directly to system ground plane; decoupling capacitor recommended near pin |
| VDD | Power supply input | Supplies core logic and memory array; must remain within 2.7–3.65 V during all operations |
| NC | No-connect die pads | Not bonded; electrically isolated; no PCB routing or termination required |
Key Features
| Feature | Design Value |
|---|---|
| NoDelay™ write architecture | Eliminates write polling and timeout handling in firmware; next I²C transaction starts immediately after byte ACK |
| Ferroelectric memory process | Enables 10¹⁴ endurance and 151-year retention without degradation mechanisms inherent to floating-gate EEPROM |
| I²C timing compatibility | Supports 100 kHz, 400 kHz, and 1 MHz modes - same timing margins as standard EEPROM, easing migration |
| Hardware write protection | Single-pin (WP) global lock prevents accidental overwrites without firmware intervention or register writes |
| Low-power active operation | 100 µA at 100 kHz enables battery-backed or energy-harvesting applications with sustained logging duty cycles |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial I²C nonvolatile memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C16D-SSHM-T | EEPROM with 1 million write cycles; requires 5 ms write cycle time; no NoDelay™ capability | Limited to infrequent updates; unsuitable for high-frequency logging or real-time parameter capture | Select only when cost sensitivity outweighs endurance and latency requirements |
| MB85RC16 | F-RAM with identical 16 Kbit density and I²C interface but rated for 10¹³ endurance and 10-year retention at +85 °C | Lower retention and endurance make it less suitable for mission-critical 15+ year deployments | Consider for consumer-grade devices where 10-year data hold is sufficient |
Compared with AT24C16D-SSHM-T and MB85RC16, FM24CL16B-GTR delivers 100× higher endurance than EEPROM and 15× longer retention than competing F-RAM, making it optimal for industrial and infrastructure applications demanding guaranteed data integrity over decades.

FAQ
Is FM24CL16B-GTR pin-compatible with standard 8-pin I²C EEPROMs like AT24C16?
Yes - FM24CL16B-GTR uses identical 8-pin SOIC and DFN footprints and matches the I²C pinout (SDA, SCL, VDD, VSS, WP) of industry-standard serial EEPROMs. No PCB redesign is needed for drop-in replacement, provided WP functionality and voltage range align with system requirements.
Does FM24CL16B-GTR require external circuitry for I²C bus termination?
Yes - SDA and SCL lines require external pull-up resistors to VDD. Recommended values are 2.2 kΩ for 100 kHz, 1 kΩ for 400 kHz, and 4.7 kΩ for 1 MHz operation, calculated per I²C bus capacitance and rise-time constraints defined in the datasheet.
How does the WP pin function when left unconnected?
The WP pin is internally pulled down, so leaving it unconnected enables full memory write access. To activate hardware write protection, WP must be actively driven to VDD. Floating WP is not recommended due to potential noise-induced toggling in noisy industrial environments.
Can FM24CL16B-GTR operate reliably at 2.7 V while running at 1 MHz I²C speed?
No - the maximum I²C clock frequency is limited to 400 kHz at VDD = 2.7 V. Full 1 MHz operation is guaranteed only at VDD ≥ 2.8 V. System designers must verify voltage margin and timing compliance using the AC switching characteristics table in Rev. *L datasheet.
