Product details
Overview
M24C16-FDW6TP from STMicroelectronics is a 16-Kbit I²C-compatible EEPROM organized as 2 K × 8 bits, operating from 1.7 V to 5.5 V across –40 °C to +85 °C, with 400 kHz clock support, 16-byte page write capability, and >4 million write cycles. It serves as nonvolatile configuration storage in embedded microcontroller systems requiring low-voltage operation and robust data retention.
For engineers reviewing the M24C16-FDW6TP datasheet, M24C16-FDW6TP pinout, M24C16-FDW6TP application, or M24C16-FDW6TP equivalent, this device is selected for I²C-based parameter storage in battery-powered sensors, industrial controllers, and portable medical devices where supply voltage may dip to 1.7 V while maintaining full temperature-range write functionality.
Technical Context
The M24C16-FDW6TP implements a standard I²C slave interface with open-drain SDA and input-only SCL, supporting both byte and page write modes under hardware write protection via the WC pin. Its internal HV generator enables EEPROM programming without external high-voltage sources.
It features an auto-incrementing address counter for sequential reads, ACK polling for write cycle completion detection, and built-in power-on reset (POR) that prevents spurious writes during power ramp-up. Memory organization is fixed at 2048 bytes with no bank switching or extended addressing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 16 Kbit (2048 × 8), directly addressable via 11-bit I²C address field |
| Supply voltage range | 1.7 V to 5.5 V - supports full read/write operation across industrial temp range (–40 °C to +85 °C) |
| I²C clock frequency | Up to 400 kHz - compatible with Fast-mode I²C buses without timing margin compromise |
| Page size | 16 bytes - limits maximum atomic write burst; crossing page boundary causes wraparound to start of same page |
| Write endurance | 4,000,000 cycles at 25 °C - ensures >10 years of daily reconfiguration in firmware update logging |
| Data retention | 200 years at 55 °C - guarantees long-term calibration storage integrity in sealed industrial enclosures |
| ESD rating | ±3000 V HBM - meets IEC 61000-4-2 Level 3 for board-level robustness in factory environments |
Pinout & Package
Package: UFDFPN8 (MC), 2 mm × 3 mm, 0.5 mm pitch, ECOPACK2-compliant, wettable flank capable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SDA) | Serial Data I/O | Open-drain bidirectional bus line; requires external pull-up; shares wire-OR topology with other I²C slaves |
| 2 (SCL) | Serial Clock Input | Master-generated clock; sampled on rising edge for data capture; must be stable during SDA transitions |
| 3 (WC) | Write Control Input | Active-high hardware lock: disables all write operations when driven high; floating = enabled |
| 4 (VSS) | Ground Reference | Primary return path for VCC current; must be low-inductance connection to minimize noise coupling into SDA/SCL |
| 5 (VCC) | Supply Voltage | Power rail for core logic and EEPROM array; decoupling capacitor (10–100 nF) required near pin |
| 6–8 (NC) | No Connect | Internally unconnected; left unbonded in die; must remain unconnected on PCB |
Key Features
| Feature | Design Value |
|---|---|
| Low-voltage write enable | Full 1.7 V–5.5 V write capability across –40 °C to +85 °C - eliminates need for voltage translators in 1.8 V/2.5 V systems |
| Hardware write protection | Dedicated WC pin with level-sensitive control - prevents accidental overwrites without software intervention or I²C command overhead |
| Page write optimization | 16-byte page buffer allows single I²C transaction to program up to 16 bytes - reduces bus occupancy vs. byte-by-byte writes |
| ACK polling support | Standard I²C ACK/NACK response during write cycle - enables deterministic host-side timing without fixed delays or timers |
| ECOPACK2 packaging | Halogen-free, RoHS-compliant UFDFPN8 with wettable flanks - supports automated optical inspection (AOI) and reliable reflow soldering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar I²C EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C16D-SSHM-T (Microchip) | Same 16-Kbit size, 1.7–5.5 V, but rated only to +125 °C; lacks WC pin - write protection implemented only via software address locking | Preferred in automotive under-hood modules requiring extended temperature grade; unsuitable where hardware-level write lock is mandated | Select when AEC-Q200 qualification and extended temp are critical, and software-controlled protection suffices |
| BR24G16FJ-3GE2 (ROHM) | 16-Kbit, 1.6–5.5 V, includes built-in write protect (WP) pin and supports 1 MHz I²C; smaller 1.6 mm × 2.1 mm UDFN6 package | Better suited for space-constrained wearables; higher clock rate enables faster bulk configuration loads | Select when board area is constrained and 1 MHz I²C throughput improves system boot time |
Compared with AT24C16D-SSHM-T and BR24G16FJ-3GE2, the M24C16-FDW6TP uniquely combines hardware WC pin control, ECOPACK2 wettable-flank packaging, and validated 1.7 V write operation across full industrial temperature range - making it optimal for cost-sensitive, high-reliability industrial control designs.

FAQ
What is the function of the WC pin on M24C16-FDW6TP?
The WC (Write Control) pin is an active-high hardware lock that disables all write operations to the entire memory array when driven high. When pulled low or left floating, writes are enabled. Unlike software-based write protection, WC operates independently of I²C commands and prevents accidental overwrites during power transients or firmware faults.
Can M24C16-FDW6TP operate at 1.6 V?
No - the M24C16-FDW6TP is specified for full read/write functionality only from 1.7 V to 5.5 V across –40 °C to +85 °C. While the M24C16-F family includes a limited 1.6 V–1.7 V mode, that mode applies only to specific variants (e.g., M24C16-FMN6TP) and is restricted to read-only operation at reduced temperature ranges; M24C16-FDW6TP does not support 1.6 V operation.
How many I²C addresses does M24C16-FDW6TP support?
The M24C16-FDW6TP supports four fixed I²C slave addresses: 0xA0, 0xA2, 0xA4, and 0xA6 - determined by hardwired A0 and A1 pins on the die. These correspond to device select codes with R/W bit cleared (write mode). Address selection is implemented via bond options, not external pins, so the address is fixed per part number and cannot be changed on the PCB.
Is M24C16-FDW6TP pin-compatible with other M24C16 variants?
Yes - all M24C16-F variants in UFDFPN8 (MC) package share identical pinout and footprint, including M24C16-FDW6TP, M24C16-FMN6TP, and M24C16-FDW6T. Differences lie only in voltage grade (F), package marking, and tape/reel specifications - enabling drop-in replacement within the same package variant without layout changes.
