Product details
Overview
M24C16-DRDW8TP/K from STMicroelectronics is a 16-Kbit (2 Kbyte) I²C-compatible serial EEPROM with 16-byte page architecture, Schmitt-trigger inputs, and extended industrial temperature operation up to 105 °C. It features an additional 16-byte lockable Identification Page for device ID storage or application parameters, operates across 1.7 V–5.5 V, and delivers 4 ms byte/page write cycles - deployed in automotive body control modules, industrial sensor nodes, and smart meter calibration data retention.
For engineers reviewing the M24C16-DRDW8TP/K datasheet, M24C16-DRDW8TP/K pinout, M24C16-DRDW8TP/K application, or M24C16-DRDW8TP/K equivalent, key selection criteria include I²C bus speed support (1 MHz/400 kHz/100 kHz), WC pin-based hardware write protection, ECC-enhanced data integrity, and AEC-Q100 Grade 2 qualification for automotive use.
Technical Context
The M24C16-DRDW8TP/K implements a true EEPROM cell structure with embedded Error Correction Code (ECC x 1) logic, enabling single-bit error correction and improving long-term data reliability in harsh environments. Its I²C slave interface supports standard, fast, and fast-plus modes, with ACK polling capability to minimize software wait time during write cycles.
It uses a dedicated Write Control (WC) input to globally inhibit all write operations - including memory array and Identification Page writes - when driven high. The Identification Page (addressed via device type identifier 1011b) provides factory-programmed ST device codes (20h/E0h/0Bh) and user-writable fields that can be permanently locked to read-only mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 16 Kbits (2048 × 8 bits), organized as 128 pages of 16 bytes - enables efficient block-level firmware parameter updates. |
| I²C speed support | 1 MHz / 400 kHz / 100 kHz - compatible with legacy and high-speed microcontroller I²C peripherals without clock stretching. |
| Write cycle endurance | 4 million cycles at 25 °C; 1.2 million at 85 °C; 900 k at 105 °C - ensures reliable field recalibration in thermal-cycling applications. |
| Data retention | 50+ years at 105 °C; 200 years at 55 °C - meets long-lifecycle requirements for industrial and automotive electronics. |
| Operating voltage | 1.7 V to 5.5 V - supports direct interfacing with 1.8 V, 3.3 V, and 5 V logic systems without level shifters. |
| ESD protection | 4000 V HBM - enhances robustness against handling and board-level electrostatic discharge events. |

Pinout & Package
TSSOP8 (DW) package: 8-lead thin shrink small outline, 3 mm × 6.4 mm, 0.65 mm pitch, RoHS-compliant and halogen-free (ECOPACK2®).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A0) | Chip Enable Address | LSB of hardware device address; tied low/high to select one of four possible I²C addresses on shared bus. |
| 2 (A1) | Chip Enable Address | MSB of hardware device address; used with A0 to configure unique I²C slave address (1010xx0/1). |
| 3 (VSS) | Ground reference | System ground return path; must be low-impedance connection to minimize noise coupling into SDA/SCL. |
| 4 (SDA) | Serial Data I/O | Open-drain bidirectional line requiring external pull-up resistor; shares bus with other I²C devices. |
| 5 (SCL) | Serial Clock Input | Master-generated clock signal; rising edge samples SDA, falling edge allows SDA transitions. |
| 6 (WC) | Write Control Input | Hardware write lock: high = full memory + ID page write disabled; low or floating = write enabled. |
| 7 (VCC) | Supply voltage | Core power supply (1.7–5.5 V); decoupling capacitor required within 10 mm of pin for stable operation. |
| 8 (NC) | No Connect | Internally unconnected; must remain unconnected on PCB to avoid parasitic coupling or latch-up risk. |
Key Features
| Feature | Design Value |
|---|---|
| Identification Page with lock | 16-byte dedicated area storing ST device ID (20h/E0h/0Bh) and user parameters; permanently read-only after Lock ID command. |
| ECC x 1 logic | Embedded single-bit error correction improves data integrity over lifetime - critical for calibration and configuration storage. |
| Schmitt-trigger inputs | SDA and SCL inputs reject noise spikes up to 30% VCC, eliminating external filtering components in noisy industrial environments. |
| Short write cycle time | Byte and page writes complete within 4 ms max - reduces MCU blocking time and improves system responsiveness. |
| Extended voltage range | 1.7 V minimum operation enables compatibility with brown-out conditions in battery-backed systems and low-power MCUs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C16D-SSHM-T (Microchip) | Same 16-Kbit capacity, TSSOP8, 1.7–5.5 V, but lacks Identification Page and ECC logic; rated only to 85 °C. | Not qualified for AEC-Q100; unsuitable for under-hood automotive use or continuous 105 °C industrial deployments. | Select only for cost-sensitive consumer applications where extended temperature and ECC are not required. |
| BR24G16FJ-3GE2 (ROHM) | 16-Kbit, TSSOP8, 1.7–5.5 V, includes write-protect pin and 105 °C rating, but no dedicated Identification Page or factory ID code. | Supports automotive use but lacks ST's standardized ID page structure for device authentication and firmware binding. | Prefer when hardware write protection is needed without requirement for ST-specific identification or lockable metadata fields. |

FAQ
What is the function of the WC pin on the M24C16-DRDW8TP/K?
The WC (Write Control) pin is a hardware-level write protection input. When driven high, it disables all write operations - including byte/page writes to the main memory array and writes to the Identification Page. When low or left floating, writes are enabled. This feature prevents accidental overwrites during power-up/down or firmware glitches without requiring software intervention.
Does the M24C16-DRDW8TP/K support 1 MHz I²C communication?
Yes, the M24C16-DRDW8TP/K fully supports 1 MHz I²C Fast-Plus mode per its datasheet specifications. It meets timing requirements for tBUF, tHD:STA, tSU:STA, and tLOW at 1 MHz with VCC ≥ 2.5 V. External pull-up resistors must be sized according to bus capacitance - typically ≤ 1.5 kΩ for Cbus ≤ 100 pF - to ensure valid signal rise times.
How is the Identification Page different from regular memory pages?
The Identification Page is a dedicated 16-byte area addressed using device type identifier 1011b (vs. 1010b for main memory). It contains factory-programmed ST device codes (20h/E0h/0Bh) in bytes 0–2 and user-writable space in bytes 3–15. Unlike main memory, it can be permanently locked to read-only mode via the Lock ID instruction - preventing any further writes even if WC is low.
Is the M24C16-DRDW8TP/K pin-compatible with other M24C16 variants?
Yes, the M24C16-DRDW8TP/K uses the TSSOP8 (DW) package and shares identical pinout and electrical characteristics with other M24C16-DRE variants in the same package - including M24C16-DWDW8TP/K and M24C16-DMDW8TP/K. Differences lie only in temperature grade, packaging marking, and reel specification; no PCB redesign is needed for substitution within the DW package family.
