2.4.7 RF
EEPROM
The STM32F30x/31x microcontroller has two embedded I
2
C peripherals that can be
connected to any device supporting the I
2
C protocol. An RF EEPROM daughter board can
be connected to STM32303C-EVAL via the I
2
C interface.

RF EEPROM daughter board
The M24LR64-R device is a dual-interface, electrically erasable programmable memory
(EEPROM). It features an I
2
C 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 8192 × 8 bits in I
2
C mode and as 2048 × 32 bits in ISO 15693
and ISO 18000-3 mode 1 RF modes.
