Product details
Overview
M95080-DRMF3TG/K from STMicroelectronics is an automotive-grade 8-Kbit serial SPI EEPROM with AEC-Q100 Grade 0 qualification, operating up to 145 °C at VCC = 2.5–5.5 V. It features 1024 × 8-bit memory organized in 32 pages of 32 bytes, embedded ECC logic for data integrity, and a dedicated 32-byte lockable Identification Page. Used for storing calibration data, VIN, firmware version, or configuration parameters in engine control units and ADAS modules.
For engineers reviewing the M95080-DRMF3TG/K datasheet, M95080-DRMF3TG/K pinout, M95080-DRMF3TG/K application, or M95080-DRMF3TG/K equivalent, key selection criteria include high-temperature endurance (600 k write cycles at 125 °C), 20 MHz max clock (≥4.5 V), page-write time ≤4 ms, and hardware-based block protection (1/4, 1/2, or full memory).
Technical Context
This SPI EEPROM implements CPOL=0/CPHA=0 and CPOL=1/CPHA=1 modes with rising-edge input sampling and falling-edge output shifting. Its protocol includes edge- and level-sensitive Chip Select (S) for robust command initiation after power-up, plus a dedicated HOLD pin to pause ongoing transfers without resetting the clock sequence.
The device integrates a non-volatile Status Register with WIP/WEL/BP1/BP0/SRWD bits for real-time write status monitoring, write enable latching, configurable block protection, and SR write disable tied to both SRWD bit state and physical W pin voltage - enabling secure, field-updatable memory partitioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 8 Kbit (1024 × 8 bits), organized as 32 pages × 32 bytes - enables efficient firmware parameter storage with minimal bus overhead. |
| Max clock frequency | 20 MHz at VCC ≥ 4.5 V - supports high-throughput configuration loading in real-time automotive control loops. |
| Write cycle endurance | 600 k cycles at 125 °C - ensures reliable recalibration logging over full vehicle lifetime under hood conditions. |
| Data retention | 50 years at 125 °C - guarantees long-term integrity of safety-critical calibration data without refresh. |
| Operating temperature | −40 °C to +145 °C - qualified per AEC-Q100 Grade 0 for placement in powertrain and transmission control modules. |
| Write protection | Hardware-configurable via BP1/BP0 bits (1/4, 1/2, or full memory) + SRWD/W pin interlock - prevents accidental overwrite of critical boot or security parameters. |
| ECC support | Embedded single-bit error correction logic - detects and corrects bit flips caused by radiation or voltage transients in automotive environments. |
Pinout & Package
Package: TSSOP8 (DW), 169 mil width, RoHS-compliant and halogen-free ECOPACK2®.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| S | Chip Select | Edge- and level-sensitive active-low enable; must transition high→low to initiate any command - prevents spurious writes during power ramp. |
| C | Serial Clock | Input clock synchronizing all SPI transfers; supports CPOL=0/CPHA=0 and CPOL=1/CPHA=1 modes - compatible with most MCU SPI peripherals. |
| D | Serial Data Input | Latches instruction, address, and write data on rising edge - MSB-first, byte-aligned framing required for valid command decoding. |
| Q | Serial Data Output | Drives read data on falling edge; high-impedance when deselected or in Hold mode - enables multi-device SPI bus sharing. |
| HOLD | Hold Control | Pauses ongoing SPI transfer (e.g., mid-page write) without deselecting device - maintains internal state for resumed communication. |
| W | Write Protect | Hardware interlock for Status Register writes when SRWD = 1 - physically disables reconfiguration of protection settings in deployed systems. |
| VCC | Supply Voltage | 2.5–5.5 V operation with 4.5 V min for 20 MHz mode - supports wide-input automotive power rails including post-regulated 3.3 V and 5 V domains. |
| VSS | Ground | Reference for all I/O and internal logic - requires low-impedance connection to minimize noise coupling into sensitive EEPROM cells. |
Key Features
| Feature | Design Value |
|---|---|
| Identification Page | 32-byte dedicated memory region readable via RDID and lockable via LID - stores immutable device ID, production lot, or cryptographic keys. |
| Schmitt trigger inputs | On all digital pins (S, C, D, HOLD, W) - rejects noise spikes up to 30% VCC, eliminating external RC filtering in harsh EMI environments. |
| Short write cycle time | ≤4 ms for both byte and page writes - reduces CPU wait time and improves system responsiveness during configuration updates. |
| ESD protection | 4000 V HBM - meets automotive assembly and handling requirements without additional protection circuitry. |
| Low-power standby | ICC1 ≤ 1 µA at VCC = 5.5 V - minimizes quiescent current in always-on vehicle networks like CAN gateway modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial SPI EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT25DF041A-SSH-T | 4-Mbit density, no built-in ECC, max 85 °C industrial rating, no Identification Page. | Lacks AEC-Q100 qualification and high-temp endurance - suitable only for cabin electronics, not powertrain. | Select only if higher density is needed and automotive temperature grade is not required. |
| BR24G08FJ-3GE2 | 8-Kbit, I²C interface (not SPI), 105 °C max, no HOLD pin, no SRWD/W interlock. | Requires I²C master; lacks hardware write-lock security and 145 °C capability - limited to infotainment subsystems. | Choose only for space-constrained designs where I²C bus already exists and security is less critical. |

FAQ
What is the maximum clock frequency supported by M95080-DRMF3TG/K at 3.3 V supply?
At VCC = 3.3 V, the device supports up to 10 MHz clock frequency, as specified in the datasheet's AC characteristics table (Table 12). This ensures compatibility with standard 3.3 V microcontrollers while maintaining reliable timing margins across temperature and process variation.
How does the Identification Page differ from regular memory pages?
The Identification Page is a dedicated 32-byte region accessible only via RDID/WRID instructions - not through standard READ/WRITE commands. It can be permanently locked in read-only mode using the LID instruction, preventing overwrite of factory-programmed IDs or user-defined security keys.
Can the Block Protect bits be modified after initial programming?
Yes, BP1/BP0 bits can be rewritten via WRSR instruction - but only if SRWD = 0, or if SRWD = 1 and the W pin is held high. If W is low while SRWD = 1, the Status Register becomes permanently write-locked until W is raised, providing tamper-resistant configuration lockdown.
Is M95080-DRMF3TG/K pin-compatible with earlier M95080 variants?
Yes - M95080-DRMF3TG/K uses the TSSOP8 (DW) package identical to M95080-DW and M95080-WMN, with identical pinout, footprint, and solder profile. No PCB redesign is needed when upgrading to the A145-grade version for higher-temperature applications.
