Description
The M24LR16E-R device is a dual-interface, electrically erasable programmable memory
(EEPROM). It features an I
also a contactless memory powered by the received carrier electromagnetic wave. The
M24LR16E-R is organized as 2048 × 8 bits in the I
15693 and ISO 18000-3 mode 1 RF mode.
The M24LR16E-R also features an energy harvesting analog output, as well as a user-
configurable digital output pin toggling during either RF write in progress or RF busy mode.

I
devices carry a built-in 4-bit device type identifier code (1010) in accordance with the I
bus definition.
The device behaves as a slave in the I
by the serial clock. Read and Write operations are initiated by a Start condition, generated
by the bus master. The Start condition is followed by a device select code and Read/Write
bit (RW) (as described in
When writing data to the memory, the device inserts an acknowledge bit during the 9
time, following the bus master’s 8-bit transmission. When data is read by the bus master, the
bus master acknowledges the receipt of the data byte in the same way. Data transfers are
terminated by a Stop condition after an Ack for Write, and after a NoAck for Read.
In the ISO15693/ISO18000-3 mode 1 RF mode, the M24LR16E-R is accessed via the
13.56 MHz carrier electromagnetic wave on which incoming data are demodulated from the
received signal amplitude modulation (ASK: amplitude shift keying). When connected to an
antenna, the operating power is derived from the RF energy and no external power supply is
required. The received ASK wave is 10% or 100% modulated with a data rate of 1.6 Kbit/s
