Product details
Overview
AT24C04-10TI-2.7 from Microchip Technology (formerly Atmel) is a 4-kbit (512 × 8) I²C-compatible serial EEPROM optimized for low-voltage embedded systems. It operates from 2.7V to 5.5V, supports 100 kHz I²C bus speed, features hardware write protection via the WP pin, and delivers 1 million write cycles with 100-year data retention. It is used in industrial sensor calibration storage, power meter configuration memory, and automotive body control module parameter backup.
For engineers reviewing the AT24C04-10TI-2.7 datasheet, AT24C04-10TI-2.7 pinout, AT24C04-10TI-2.7 application, or AT24C04-10TI-2.7 equivalent, key selection criteria include its 2.7–5.5V supply range, 100 kHz I²C timing compliance at low voltage, 16-byte page write capability, industrial temperature rating (−40°C to +85°C), and TSSOP-8 package footprint compatibility.
Technical Context
The AT24C04-10TI-2.7 implements a two-wire I²C interface with Schmitt-triggered, noise-filtered SDA and SCL inputs. Its internal architecture organizes 4096 bits into 32 pages of 16 bytes each, requiring a 9-bit word address for random access. Device addressing uses A2 and A1 pins (A0 is NC), enabling up to four devices on a shared bus.
Write operations support both byte and 16-byte page modes, with self-timed internal write cycles completing in ≤10 ms. Standby current is 4.0 µA max at 2.7V, and the WP pin enables hardware-level protection of the full 4K array when pulled high.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 4096 bits (512 × 8), organized as 32 pages × 16 bytes - enables efficient parameter storage with minimal I²C transactions per page. |
| Supply Voltage Range | 2.7V to 5.5V - supports direct interfacing with 3.3V microcontrollers and legacy 5V systems without level shifting. |
| I²C Clock Frequency | 100 kHz maximum at 2.7V - ensures reliable timing margin in noisy industrial environments with long traces or multiple slaves. |
| Write Cycle Time | ≤10 ms - defines minimum delay between write commands; impacts firmware polling or timeout design for write completion. |
| Endurance | 1 million write cycles - guarantees >10 years of daily reconfiguration in field-deployed equipment with 270+ writes/day. |
| Data Retention | 100 years at 25°C - ensures stored calibration or security keys remain valid across product lifecycle without refresh. |
| Operating Temperature | −40°C to +85°C - qualified for under-hood automotive, factory automation, and outdoor metering applications. |
Pinout & Package
AT24C04-10TI-2.7 is supplied in an 8-lead TSSOP package (JEDEC MO-153, 0.170" wide), measuring 4.5 mm × 3.0 mm × 1.2 mm max height, with 0.65 mm lead pitch and gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 | No Connect (NC) | Not bonded internally; must be left unconnected - omission does not affect device addressing or functionality. |
| A1 | Device Address Input | Hardwired input used with A2 to select one of four possible I²C addresses (1010xx0/1) on shared bus. |
| A2 | Device Address Input | Hardwired input used with A1 to configure device address; enables multi-device topology without software address remapping. |
| GND | Ground Reference | System return path for VCC and I/O; requires low-impedance connection to minimize noise coupling into SDA/SCL. |
| VCC | Power Supply | 2.7–5.5V main supply; decoupling capacitor (0.1 µF ceramic) required within 5 mm for stable I²C operation. |
| WP | Write Protect Control | Active-high hardware lock: tied to VCC blocks all writes to entire 4K array; tied to GND enables full read/write access. |
| SCL | I²C Clock Input | Open-drain compatible input; requires external pull-up resistor (typically 2.2–10 kΩ) to VCC for proper bus timing. |
| SDA | I²C Bidirectional Data | Open-drain I/O shared across bus; same pull-up as SCL; supports wire-OR with other I²C peripherals. |
Key Features
| Feature | Design Value |
|---|---|
| Low-voltage I²C interface | Guaranteed 100 kHz operation down to 2.7V - eliminates need for voltage translators in mixed-supply systems. |
| Hardware write protection | WP pin disables all write operations when high - prevents accidental overwrites during power-up/down or firmware faults. |
| 16-byte page write mode | Reduces I²C transaction count by 16× vs. byte writes - cuts firmware execution time and bus occupancy in bulk configuration updates. |
| Schmitt-trigger inputs | Suppresses noise-induced glitches on SDA/SCL - improves robustness in electrically noisy industrial enclosures or automotive harnesses. |
| Industrial temperature grade | Qualified from −40°C to +85°C - meets AEC-Q100 stress requirements for non-safety-critical automotive ECUs. |
Applications
| Smart Energy Meter | Automotive Body Control Module |
|---|---|

IC Role / Device Role / Timing Role: Low-power nonvolatile memory retaining critical therapy data during battery swaps or brownouts. Use Value: 4.0 µA max standby current at 2.7V extends battery life between replacements in portable medical devices. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics M24C04-RMN6TP | Same 4K size, 2.5–5.5V range, 400 kHz max at 5V; no 100 kHz guarantee below 3.3V; TSSOP-8 pinout identical. | Higher speed at 5V but less margin at 2.7V; lacks explicit 100 kHz spec under low-VCC conditions. | Select if system operates ≥3.3V and requires faster writes; verify timing margins at actual VCC min. |
| ON Semiconductor CAT24C04HU4I-GT3 | Identical 4K organization, 2.7–5.5V, 100 kHz @ 2.7V, same TSSOP-8 package; endurance rated at 100k cycles (not 1M). | Lower endurance makes it unsuitable for frequent-field-update applications like sensor recalibration. | Choose for cost-sensitive consumer designs with <1000 lifetime writes; avoid in industrial calibration storage. |
Compared with AT24C04-10TI-2.7, M24C04-RMN6TP offers higher speed at nominal voltage but weaker low-VCC timing assurance, while CAT24C04HU4I-GT3 matches voltage and timing specs but trades 10× lower endurance - making AT24C04-10TI-2.7 optimal for reliability-critical industrial and automotive use cases.

FAQ
What is the maximum I²C clock frequency supported by AT24C04-10TI-2.7 at 2.7V?
The AT24C04-10TI-2.7 supports a maximum I²C clock frequency of 100 kHz when operating at 2.7V. This is explicitly guaranteed in the AC Characteristics table under "2.7-, 2.5-, 1.8-volt" conditions. At 5.0V, it supports up to 400 kHz, but the -2.7 suffix denotes qualification and specification for the lower-voltage regime where 100 kHz is the validated limit.
Is the A0 pin functional on AT24C04-10TI-2.7?
No, the A0 pin is a no-connect (NC) on AT24C04-10TI-2.7. Per the Device Addressing section, the AT24C04 uses only A2 and A1 for hard-wired device addressing, allowing up to four devices on a single I²C bus. The A0 pin is not bonded internally and must be left unconnected in PCB layout.
How does the Write Protect (WP) pin function on AT24C04-10TI-2.7?
When the WP pin of AT24C04-10TI-2.7 is driven high (to VCC), it disables all write operations to the entire 4K memory array. When WP is low (tied to GND), normal read and write operations are enabled. This hardware-level protection prevents accidental or malicious overwrites during power transitions or firmware errors.
What package type is used for AT24C04-10TI-2.7?
AT24C04-10TI-2.7 is packaged in an 8-lead TSSOP (Thin Shrink Small Outline Package), designated as package code "8T" in Microchip's ordering information. Its dimensions are 4.5 mm × 3.0 mm × 1.2 mm max height, with 0.65 mm lead pitch and gull-wing leads compliant with JEDEC MO-153.
Does AT24C04-10TI-2.7 support page write operations, and what is the page size?
Yes, AT24C04-10TI-2.7 supports 16-byte page write operations. Internally organized as 32 pages of 16 bytes each, it allows up to 16 sequential bytes to be written in a single I²C transaction - significantly improving write efficiency compared to byte-by-byte programming.
