CAT24M01 Overview

Part: CAT24M01YI-GT3 — onsemi (ON Semiconductor)

Type: I²C Serial EEPROM (1-Mb)

Description: 1-Mb (131,072 × 8) I²C serial EEPROM with a 1.8–5.5 V supply, 256-byte page write buffer, and support for Standard, Fast and Fast-Plus (1 MHz) modes with on-chip ECC.

Operating Conditions:

  • Supply voltage: 1.8–5.5 V (Fast-Plus 1 MHz: 2.5–5.5 V)

CAT24M01 Absolute Maximum Ratings

ParametersRatingsUnits
Storage Temperature Range, T STG-65 to +150° C
Junction Temperature, T J+150° C
Voltage on any Pin with Respect to Ground (Note 1)-0.5 to +6.5V

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected.

  1. The DC input voltage on any pin should not be lower than -0.5 V or higher than V CC + 0.5 V. During transitions, the voltage on any pin may undershoot to no less than -1.5 V or overshoot to no more than V CC + 1.5 V, for periods of less than 20 ns.
