Product details
Overview
FM24CL04B-GTR from Cypress Semiconductor is a 4-Kbit (512 × 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 replaces I²C EEPROM in high-write-cycle applications such as industrial data logging and real-time metering.
For engineers reviewing the FM24CL04B-GTR datasheet, FM24CL04B-GTR pinout, FM24CL04B-GTR application, or FM24CL04B-GTR equivalent, key selection criteria include write speed parity with RAM, absence of write polling, I²C bus compatibility up to 1 MHz, and guaranteed industrial temperature operation without refresh or wear leveling overhead.
Technical Context
The FM24CL04B-GTR implements a true nonvolatile memory cell using lead zirconate titanate (PZT) ferroelectric capacitors, enabling byte-level writes at I²C bus speed without internal charge pumps or write latency. Its 9-bit addressing scheme combines an 8-bit word address with a 1-bit page select bit embedded in the slave address byte.
As a slave-only I²C device, it supports standard START/STOP conditions, 7-bit slave address format (1010b + A2/A1 + PS + R/W), and ACK/NACK handshaking. Write protection is controlled via the dedicated WP pin, and all address pins (A2, A1) are internally pulled down for default single-device configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 4 Kbit (512 × 8), directly addressable without page boundaries or erase cycles |
| Interface | I²C-compatible 2-wire serial, supports 100 kHz, 400 kHz, and 1 MHz modes |
| Write endurance | 100 trillion (10¹⁴) read/write cycles - eliminates wear leveling in firmware |
| Data retention | 151 years at +85 °C - enables long-term unpowered storage without refresh |
| Write latency | NoDelay™ - byte written immediately after ACK; no polling or timeout required |
| Supply voltage | 2.7 V to 3.65 V - compatible with 3.3 V logic systems without level shifting |
| Operating temp | –40 °C to +85 °C - qualified for industrial control and metering environments |
Pinout & Package
FM24CL04B-GTR is housed in an 8-pin SOIC package (3.9 mm × 4.9 mm, 1.27 mm pitch) with gull-wing leads and RoHS-compliant finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A2, A1 | Device select input | Set slave address bits; internally pulled down - defaults to 00 for base address 0xA0 |
| SDA | Bi-directional I²C data line | Open-drain, Schmitt-triggered input; requires external pull-up; supports multi-master arbitration |
| SCL | I²C clock input | Input only; Schmitt-triggered; master-generated clock synchronizes all transfers |
| WP | Hardware write protect | Active-high; ties entire memory map to read-only when driven to VDD |
| VSS | Ground reference | System ground connection; must be low-impedance for noise immunity during fast writes |
| VDD | Power supply | 2.7–3.65 V supply; powers internal logic and ferroelectric array; no internal regulation |
Key Features
| Feature | Design Value |
|---|---|
| NoDelay™ write architecture | Eliminates software wait states and hardware polling loops - reduces CPU overhead per write by >95% vs. EEPROM |
| Ferroelectric memory cell | Enables true random-access nonvolatile storage without erase-before-write or block management |
| I²C timing compatibility | Direct hardware replacement for legacy 4-Kbit I²C EEPROMs (e.g., AT24C04) without firmware changes |
| Low-power write operation | 100 µA active current at 100 kHz - avoids voltage boosting circuits that increase EEPROM power and EMI |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial nonvolatile memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C04D-SSHM-T | 4-Kbit I²C EEPROM; 1M write cycles; 5 ms typical write time; requires polling | Limited to low-write-frequency applications due to endurance and latency constraints | Select only if cost sensitivity outweighs write performance and longevity requirements |
| MB85RC04V | 4-Kbit I²C FRAM; same 10¹⁴ endurance and NoDelay™ writes; 1.7–5.5 V supply range | Broadens system voltage design flexibility but lacks integrated WP pin | Prefer when wider VDD range or alternate package (TSSOP8) is needed; verify WP functionality via GPIO |
Compared with AT24C04D-SSHM-T, FM24CL04B-GTR delivers 100 million× higher endurance and zero-latency writes; versus MB85RC04V, it offers hardware write protection and tighter 2.7–3.65 V regulation - critical for stable 3.3 V industrial bus operation.

FAQ
Is FM24CL04B-GTR pin-compatible with standard 4-Kbit I²C EEPROMs like AT24C04?
Yes - FM24CL04B-GTR uses identical 8-pin SOIC packaging and matches the pinout (VSS, SDA, SCL, VDD, WP, A1, A2, NC) and I²C electrical signaling of AT24C04-series EEPROMs. No PCB redesign is needed for drop-in replacement, though WP pin behavior differs (active-high vs. AT24C04's active-low).
Does FM24CL04B-GTR require special I²C timing or firmware modifications?
No - it fully complies with standard I²C protocol timing (including START/STOP, ACK/NACK, and clock stretching). Firmware designed for EEPROM works unchanged; only polling loops can be removed since writes complete instantly upon ACK.
What is the role of the NC pin (Pin 5) in FM24CL04B-GTR?
Pin 5 is a no-connect terminal - physically present but electrically unconnected inside the die. It must remain unconnected on the PCB; routing traces or applying voltage to this pin may cause mechanical stress or unintended coupling in high-density layouts.
How does FM24CL04B-GTR handle power loss during a write operation?
Because writes occur at bus speed with no internal delay, data is committed to the ferroelectric array before the I²C transaction completes. If VDD drops mid-transfer, only the incomplete byte is lost - unlike EEPROM, there is no risk of partial-page corruption or array damage from interrupted high-voltage programming.
