Product details
Overview
AT24C01-10SI-1.8 from Microchip Technology (formerly Atmel) is a 1K-bit serial EEPROM IC optimized for low-voltage embedded systems, featuring 128 × 8-bit memory organization, 2-wire I²C-compatible interface, and guaranteed operation from 1.8V to 5.5V. It supports 100 kHz clock rate at 1.8V, delivers 4-byte page write capability, and provides 1 million write cycles with 100-year data retention - deployed in industrial sensor nodes, power metering firmware storage, and automotive body control modules.
For engineers reviewing the AT24C01-10SI-1.8 datasheet, AT24C01-10SI-1.8 pinout, AT24C01-10SI-1.8 application, or AT24C01-10SI-1.8 equivalent, key selection criteria include its 1.8V minimum supply, SOIC-8 package compatibility, I²C timing compliance at extended low voltage, and endurance/reliability specs under industrial temperature range (-40°C to +85°C).
Technical Context
The AT24C01-10SI-1.8 implements a standard two-wire (I²C) serial interface with open-drain SDA and edge-triggered SCL pins, supporting bidirectional data transfer using start/stop conditions and 7-bit slave addressing. Its internal architecture uses nonvolatile floating-gate EEPROM cells with on-chip charge pump for write operations.
It operates in standby mode after STOP condition completion or power-up, drawing only 0.6 µA typical at 1.8V; write cycles are self-timed up to 10 ms maximum and disable all inputs during execution. Memory is organized as 128 individually addressable 8-bit words, with page boundaries aligned to 4-word increments.

Yes, AT24C01-10SI-1.8 implements a fully compliant two-wire I²C interface with START/STOP conditions, 7-bit slave addressing (A0–A2 configurable), and ACK/NACK handshaking. It supports standard-mode (100 kHz) timing at 1.8V and fast-mode (400 kHz) at 5V, meeting I²C-bus specification v2.1 requirements.
What package type is used for AT24C01-10SI-1.8?
AT24C01-10SI-1.8 is packaged in an 8-lead JEDEC SOIC (8S1), with 1.27 mm lead pitch, 4.0 mm × 5.0 mm body size, and gull-wing leads. This package is pin-compatible with industry-standard SOIC-8 footprints and supports reflow soldering per J-STD-020.
How many write cycles can AT24C01-10SI-1.8 endure?
AT24C01-10SI-1.8 is rated for 1 million write cycles per memory location, verified under industrial conditions (VCC = 1.8V–5.5V, TA = -40°C to +85°C). This endurance enables robust use in applications such as firmware parameter logging, calibration storage, and event counters without premature wear-out.
Is AT24C01-10SI-1.8 qualified for automotive applications?
AT24C01-10SI-1.8 is rated for industrial temperature (-40°C to +85°C) and is not AEC-Q100 qualified. While it is used in some automotive body electronics, Microchip offers automotive-grade variants (e.g., AT24C01C-SSHM-T) with extended temp and qualification - AT24C01-10SI-1.8 itself is intended for industrial, medical, and consumer systems.
