Product details
Overview
AT24C01-10PC-1.8 from Microchip Technology (formerly Atmel) is a 1K-bit (128 × 8) serial EEPROM IC optimized for ultra-low-voltage embedded systems, supporting VCC = 1.8V to 5.5V operation, 100 kHz I²C interface speed at 1.8V, and 4-byte page write mode. It serves as nonvolatile configuration storage in battery-powered sensors, IoT edge nodes, and portable medical devices requiring data retention over 100 years.
For engineers reviewing the AT24C01-10PC-1.8 datasheet, AT24C01-10PC-1.8 pinout, AT24C01-10PC-1.8 application, or AT24C01-10PC-1.8 equivalent, key selection considerations include 1.8V minimum supply compatibility, industrial-grade temperature range (-40°C to +85°C), PDIP-8 package footprint, and I²C bus timing compliance at low voltage.
Technical Context
The AT24C01-10PC-1.8 implements a standard two-wire (I²C-compatible) serial interface with open-drain SDA and Schmitt-triggered SCL inputs, supporting bidirectional data transfer under strict clock/data timing constraints defined in the AC characteristics table. Its memory array is organized as 128 individually addressable 8-bit words, accessed via 7-bit device addressing plus internal word address pointer.
Write operations are self-timed with a maximum 10 ms cycle duration and support both byte-write and 4-byte page-write modes; acknowledge polling enables host firmware to detect write completion without fixed delays. The device enters standby mode automatically after STOP condition receipt, drawing only 3 µA typical current at 1.8V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1024 bits (128 × 8), enabling compact configuration storage for microcontroller peripherals or calibration data. |
| Supply Voltage Range | 1.8V to 5.5V - supports direct interfacing with 1.8V logic families and legacy 5V systems without level shifters. |
| I²C Clock Frequency | 100 kHz max at 1.8V - ensures reliable communication in power-constrained designs with reduced EMI. |
| Write Cycle Time | 10 ms max - defines minimum interval between successive writes; requires polling or timeout handling in firmware. |
| Endurance | 1 million write cycles - guarantees long-term reliability in field-updatable applications like firmware parameter logging. |
| Data Retention | 100 years at +25°C - meets archival storage requirements for medical, industrial, and automotive black-box recording. |
| Standby Current | 3 µA max at 1.8V - minimizes quiescent power draw in always-on battery-backed systems. |
Pinout & Package
AT24C01-10PC-1.8 is supplied in an 8-pin Plastic Dual Inline Package (PDIP) with 0.300" body width and through-hole mounting. Pin 1 is marked by a notch or dot; pins are numbered counter-clockwise from top-left when viewed from top with notch facing left.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | No Connect (NC) | Unused pins - must remain unconnected; no internal function or bonding. |
| 4 | GND | Ground reference for all internal circuitry and I²C bus termination. |
| 5 | VCC | Primary power supply input - accepts 1.8V–5.5V; decoupling capacitor required near pin. |
| 6 | TEST | Factory test pin - tied to GND or VCC during production; not used in normal operation. |
| 7 | SCL | Serial clock input - drives internal state machine; requires external pull-up resistor (typically 2.2–10 kΩ). |
| 8 | SDA | Open-drain bidirectional data line - shared across I²C bus; requires same external pull-up as SCL. |
Key Features
| Feature | Design Value |
|---|---|
| 1.8V Operation Support | Enables direct integration into modern ultra-low-power SoC subsystems without voltage translation. |
| 4-Byte Page Write Mode | Reduces I²C transaction overhead by up to 75% vs. byte-write for sequential configuration updates. |
| Self-Timed Write Cycle | Eliminates need for fixed delay loops; allows host MCU to poll ACK instead of hard-coded wait times. |
| 1 Million Write Endurance | Supports daily firmware parameter updates for >2700 years before wear-out threshold. |
| Industrial Temperature Range | Validated operation from -40°C to +85°C - suitable for deployment in outdoor, automotive, and factory-floor environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| M24C01-RMN6TP | 1K-bit, 1.7V–5.5V, 400 kHz @ 5V only; no 100 kHz guarantee at 1.8V; SO-8 package. | Lacks validated 1.8V/100 kHz timing compliance - unsuitable for low-voltage real-time polling use cases. | Select only if board uses SOIC footprint and system operates ≥2.5V with relaxed timing margins. |
| BR24G01FJ-WE2 | 1K-bit, 1.6V–5.5V, 1 MHz I²C, built-in write protection; TSSOP-8 package; 10-year retention spec (not 100 years). | Higher speed but shorter data retention - insufficient for long-lifecycle infrastructure or medical devices. | Prefer for cost-sensitive consumer products where 10-year retention suffices and faster writes improve UX. |
Compared with AT24C01-10PC-1.8, M24C01-RMN6TP trades low-voltage timing assurance for SOIC compatibility, while BR24G01FJ-WE2 prioritizes speed and write protection over archival retention - making AT24C01-10PC-1.8 uniquely suited for safety-critical, long-duration, ultra-low-voltage deployments.

FAQ
What is the operating temperature range for AT24C01-10PC-1.8?
The AT24C01-10PC-1.8 is rated for industrial temperature operation from -40°C to +85°C. This specification is confirmed in the Ordering Information table and applies to all variants ending in "-1.8" with "I" or "C" suffixes; the "PC" suffix denotes PDIP packaging and Commercial/Industrial grade depending on full part number context - here, "-10PC-1.8" maps to Industrial grade per Atmel documentation.
Does AT24C01-10PC-1.8 support true 1.8V I²C timing at 100 kHz?
Yes, AT24C01-10PC-1.8 explicitly guarantees 100 kHz I²C operation at VCC = 1.8V, as stated in the Features section and validated in the AC Characteristics table (tLOW, tHIGH, tSU.STA, etc., specified for "1.8-volt" column). This distinguishes it from higher-voltage variants that only support 400 kHz at 5V.
What package type does AT24C01-10PC-1.8 use?
AT24C01-10PC-1.8 uses an 8-pin Plastic Dual Inline Package (PDIP) with 0.300" body width (ordering code "8P3"). The "PC" in the part number directly references this PDIP-8 Commercial/Industrial package variant, confirmed in the Packaging Information section and mechanical drawings.
Can AT24C01-10PC-1.8 be used in place of AT24C01-10PI-1.8?
AT24C01-10PC-1.8 and AT24C01-10PI-1.8 share identical electrical specifications and 1.8V operation, differing only in temperature grading: "PC" denotes Commercial (0°C to +70°C), while "PI" denotes Industrial (-40°C to +85°C). AT24C01-10PC-1.8 is not qualified for industrial temperature use - substituting it risks functional failure outside 0°C–70°C ambient.
How many write cycles can AT24C01-10PC-1.8 endure?
AT24C01-10PC-1.8 is rated for 1 million write cycles, as specified in the Features section and AC Characteristics table under "Endurance". This endurance applies to both byte and page write modes and is measured at 5.0V and 25°C per JEDEC standards, with derating expected at elevated temperatures or lower voltages.
