Component overview

This section describes the main characteristics of the three STMicroelectronics components

(M24LR64-R, STTS75, and STM8L101K3). It explains how to configure them for the

temperature acquisition application, and it describes the corresponding code function and

examples.

2.1.1

M24LR64-R main features

The M24LR64-R device is a dual-access electrically erasable programmable memory

(EEPROM). It features an I2C interface and can be operated from a VCC power supply. It is

also a contactless memory powered by the received carrier electromagnetic wave.

The M24LR64-R is organized as 8192x8 bits in the I2C mode and 2048x32 bits in the

ISO 15693 and ISO 18000-3 mode 1 RF mode.
