Component overview
AN3209
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.

M24LR64-R Dual interface EEPROM
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 V_CC 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.
