Product details
Overview
M95160-DFMC6TG from STMicroelectronics is a 16-Kbit serial SPI bus EEPROM organized as 2048 × 8 bits, operating from 1.7 V to 5.5 V supply and rated for −40°C to +85°C ambient. It supports 20 MHz clock speed, 32-byte page writes completing in ≤5 ms, and includes an additional lockable 32-byte Identification Page for secure parameter storage. Used in industrial control modules for firmware revision tracking and calibration data persistence.
For engineers reviewing the M95160-DFMC6TG datasheet, M95160-DFMC6TG pinout, M95160-DFMC6TG application, or M95160-DFMC6TG equivalent, key selection criteria include its ultra-low 1.7 V minimum VCC, ECOPACK2®-compliant UFDFPN8 package, 4 million write cycles, 200-year data retention, and hardware-based quarter/half/whole array write protection via BP1/BP0 bits.
Technical Context
This EEPROM implements a standard SPI interface with CPOL=0/CPHA=0 and CPOL=1/CPHA=1 mode support, using edge-triggered latching: data input (D) sampled on rising C edge, output (Q) driven on falling C edge. The internal architecture includes a status register with WIP, WEL, BP1/BP0, and SRWD bits controlling write enable, protection granularity, and software lock.
It features dual-stage write protection: hardware-level Write Protect (W) pin assertion freezes BP bit-defined protected zones, while software-controlled Status Register writes allow dynamic reconfiguration. The Identification Page-accessible only in M95160-D variants-is programmable and permanently lockable to Read-only mode, enabling secure storage of device-specific identifiers or cryptographic keys.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 16 Kbit (2048 × 8), sufficient for bootloader configuration, sensor calibration tables, or device serialization data. |
| Interface | SPI bus with 20 MHz max clock - enables fast firmware updates and real-time parameter logging without CPU overhead. |
| Write time | ≤5 ms per byte or per 32-byte page - reduces system latency during nonvolatile parameter saves. |
| VCC range | 1.7 V to 5.5 V - supports direct integration with 1.8 V logic, 3.3 V microcontrollers, and legacy 5 V systems. |
| Data retention | 200 years at 25°C - ensures long-term reliability in unattended infrastructure monitoring equipment. |
| Endurance | 4 million write cycles - accommodates frequent recalibration in test instrumentation or adaptive control loops. |
| Operating temp | −40°C to +85°C - qualified for industrial automation, automotive body electronics, and outdoor IoT gateways. |
| Protection modes | Quarter/half/whole memory array lock via BP1/BP0 bits - prevents accidental overwrite of critical boot code or security keys. |
Pinout & Package
Package: UFDFPN8 (2 mm × 3 mm, 0.5 mm pitch), ECOPACK2®-compliant, surface-mount, lead-free, halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S) | Chip Select | Active-low enable; places device in Active Power mode when low, high-impedance Q when high. |
| 2 (VSS) | Ground | Reference node for all I/O and internal circuitry; must be low-inductance connection. |
| 3 (Q) | Serial Data Output | Drives MSB-first read data on falling edge of C; high-impedance during HOLD or S high. |
| 4 (C) | Serial Clock | Input timing reference; rising edge latches D, falling edge clocks Q - defines SPI communication rhythm. |
| 5 (D) | Serial Data Input | Receives instructions, addresses, and write data MSB-first on rising edge of C. |
| 6 (VCC) | Supply Voltage | 1.7–5.5 V power rail; requires local 100 nF decoupling capacitor near pin. |
| 7 (W) | Write Protect | Hardware freeze of BP-bit-defined protected zones; must be stable during write operations. |
| 8 (HOLD) | Hold Control | Pauses ongoing SPI transaction without deselecting device; Q goes high-Z, D/C ignored. |
Key Features
| Feature | Design Value |
|---|---|
| Identification Page | 32-byte dedicated area with permanent lock capability - stores immutable device IDs or encryption keys. |
| ECOPACK2® packaging | UFDFPN8 footprint meets RoHS, REACH, and halogen-free requirements for global industrial compliance. |
| Status Register control | BP1/BP0 bits configure write-protect boundaries; SRWD bit locks status register against accidental change. |
| Low-voltage operation | 1.7 V minimum VCC enables direct interfacing with 1.8 V FPGAs and ultra-low-power MCUs. |
| Enhanced ESD protection | ±4 kV HBM - improves robustness in handling-sensitive manufacturing and field-repair environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT25160B-SSHL-T (Microchip) | 1.8–5.5 V VCC, 10 MHz max clock, no Identification Page, SO8/TSSOP8 only. | Lacks secure ID page and ultra-low 1.7 V operation; suitable for cost-sensitive consumer designs without security needs. | Select when budget constraints outweigh need for lockable ID storage or 1.7 V compatibility. |
| BR24G16FJ-3GE2 (ROHM) | I²C interface (not SPI), 1.7–5.5 V, 400 kHz max, 1.5 ms page write, no ID page. | Requires I²C-capable MCU; slower interface limits high-frequency logging; no hardware write-protection granularity. | Choose only if system already uses I²C bus and SPI pins are unavailable; avoid for secure or high-speed use cases. |
Compared with AT25160B-SSHL-T and BR24G16FJ-3GE2, M95160-DFMC6TG uniquely combines 1.7 V operation, 20 MHz SPI speed, and a lockable Identification Page - making it the only option among the three qualified for secure, low-voltage, high-throughput industrial firmware metadata storage.

FAQ
What is the function of the HOLD pin on M95160-DFMC6TG?
The HOLD pin pauses active SPI communication without deselecting the device. When asserted low while Chip Select (S) is low, Serial Data Output (Q) enters high-impedance state and Serial Clock (C) and Serial Data Input (D) are ignored. This allows the host MCU to service higher-priority interrupts mid-transaction and resume seamlessly - critical for real-time systems with deterministic timing budgets.
How does the Identification Page differ from standard memory pages?
The Identification Page is a dedicated 32-byte area accessible only in M95160-D variants like M95160-DFMC6TG. Unlike regular memory, it supports Lock ID instruction to permanently disable further writes, converting it to read-only. Its contents - such as device serial numbers or cryptographic keys - remain immune to accidental erasure or malicious overwrite after locking, satisfying secure boot and regulatory traceability requirements.
Can M95160-DFMC6TG operate reliably at 1.7 V during power-up sequences?
Yes. M95160-DFMC6TG guarantees full functionality including Read, Write, and Status Register access at 1.7 V, verified across −40°C to +85°C. Its internal voltage regulator and threshold detection circuitry ensure valid operation during brown-out conditions common in battery-backed or automotive cold-crank scenarios - eliminating need for external reset supervisors in many designs.
What package variant does M95160-DFMC6TG use, and why is it significant?
M95160-DFMC6TG uses the UFDFPN8 package: 2 mm × 3 mm, 0.5 mm pitch, ultra-thin profile. This compact, lead-free ECOPACK2®-compliant package enables high-density PCB layouts in space-constrained applications like wearable medical sensors and slim automotive ECUs. Its thermal performance and solder-joint reliability are validated for industrial reflow profiles, supporting automated assembly without yield loss.
