Product details
Overview
AT24C164-10PC-1.8 from Atmel (now Microchip) is a 16 Kbit (2048 × 8) I²C-compatible serial EEPROM optimized for ultra-low-voltage operation down to 1.8 V, featuring 10 ms max write cycle time, 1 million write endurance, and 100-year data retention. It supports cascading up to eight devices on a shared 2-wire bus and is used in battery-powered IoT sensors, embedded configuration storage, and industrial control modules requiring reliable nonvolatile memory at reduced supply voltage.
For engineers reviewing the AT24C164-10PC-1.8 datasheet, AT24C164-10PC-1.8 pinout, AT24C164-10PC-1.8 application, or AT24C164-10PC-1.8 equivalent, key selection considerations include its 1.8–5.5 V operating range, 100 kHz I²C speed at 1.8 V, hardware write protection via WP pin, 16-byte page write capability, and JEDEC SOIC-8 / PDIP-8 package compatibility.
Technical Context
The AT24C164-10PC-1.8 implements a standard two-wire (I²C) interface with open-drain SDA and edge-triggered SCL, supporting bidirectional data transfer and device addressing via A0–A2 pins. Its internal architecture organizes memory into 256 pages of 8 bytes each, enabling both byte and 16-byte page writes with automatic address incrementing within a page.
It features Schmitt-trigger inputs with noise filtering, acknowledge polling for write-cycle completion detection, and hardware-based write protection through the active-low WP pin. The device operates across commercial temperature range (0°C to +70°C) and guarantees 1 µA typical standby current at 1.8 V - critical for energy-constrained applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MICROCHIP AT24C16C-SSHM-T | Same 16 Kbit density and 1.7–5.5 V range, but rated for industrial temp (−40°C to +85°C); SOIC-8 only; no PDIP option | Preferred for extended-temperature deployments where AT24C164-10PC-1.8's commercial grade (0°C to +70°C) is insufficient | Select when ambient operating temperature exceeds +70°C or PDIP packaging is not required |
| ON SEMICONDUCTOR CAT24C16WI-GT3 | 16 Kbit, 1.8–5.5 V, 100 kHz @ 1.8 V, but offers enhanced ESD rating (4 kV HBM) and AEC-Q100 Grade 3 qualification | Targeted at automotive subsystems requiring component-level reliability validation beyond standard industrial specs | Select for automotive body electronics needing AEC-Q100 compliance and higher ESD robustness |
Compared with AT24C164-10PC-1.8, AT24C16C-SSHM-T extends temperature range without changing footprint or interface, while CAT24C16WI-GT3 adds automotive qualification and higher ESD tolerance - both retain identical memory organization and I²C protocol behavior but differ in qualification scope and package availability.

FAQ
What is the minimum operating voltage for the AT24C164-10PC-1.8?
The AT24C164-10PC-1.8 is fully specified to operate down to 1.8 V, with guaranteed 100 kHz I²C communication, 10 ms max write cycle, and valid DC/AC characteristics across the full 1.8–5.5 V range. This makes AT24C164-10PC-1.8 suitable for direct connection to 1.8 V logic without level shifters.
Does the AT24C164-10PC-1.8 support page write operations?
Yes, the AT24C164-10PC-1.8 supports 16-byte page writes, allowing up to 16 sequential bytes to be written in a single I²C transaction. This reduces bus overhead versus byte-wise writes and is enabled by internal address auto-increment within each 8-byte page boundary. AT24C164-10PC-1.8 does not wrap writes across page boundaries unless explicitly commanded.
What package types are offered for the AT24C164-10PC-1.8?
The AT24C164-10PC-1.8 is packaged in an 8-pin PDIP (8P3) with 0.300" width, compliant with JEDEC MS-001 BA. It is not offered in SOIC or TSSOP variants - those are designated by suffixes like "-SC" or "-SI". The "PC" in AT24C164-10PC-1.8 explicitly denotes the PDIP package and commercial temperature grade.
How does the write protect (WP) pin function on the AT24C164-10PC-1.8?
The WP pin on the AT24C164-10PC-1.8 is an active-low hardware lock: when pulled low (GND), write operations are enabled; when pulled high (VCC), all write attempts - including byte, page, and erase - are blocked. This provides deterministic, glitch-immune protection independent of software state. AT24C164-10PC-1.8 does not support software write protection.
Is the AT24C164-10PC-1.8 compatible with standard I²C protocols?
Yes, the AT24C164-10PC-1.8 implements a standard two-wire I²C interface compliant with Philips I²C-bus specification, supporting START/STOP conditions, 7-bit addressing (with A0–A2), ACK/NACK handshaking, and repeated START. It operates at 100 kHz up to 5.5 V and maintains full protocol compliance at 1.8 V - confirming AT24C164-10PC-1.8 interoperability with common microcontroller I²C peripherals.
