Description

using the 1/256 pulse coding mode or a data rate of 26 Kbit/s using the 1/4 pulse coding
mode.
Outgoing data are generated by the M24LR16E-R load variation using Manchester coding
with one or two subcarrier frequencies at 423 kHz and 484 kHz. Data are transferred from
the M24LR16E-R at 6.6 Kbit/s in low data rate mode and 26 Kbit/s high data rate mode. The
M24LR16E-R supports the 53 Kbit/s fast mode in high data rate mode using one subcarrier
frequency at 423 kHz.
The M24LR16E-R follows the ISO 15693 and ISO 18000-3 mode 1 recommendation for
radio-frequency power and signal interface.
The M24LR16E-R provides an Energy harvesting mode on the analog output pin Vout.
When the Energy harvesting mode is activated, the M24LR16E-R can output the excess
energy coming from the RF field on the Vout analog pin. In case the RF field strength is
insufficient or when Energy harvesting mode is disabled, the analog output pin Vout goes
into high-Z state and Energy harvesting mode is automatically stopped.
The M24LR16E-R features a user configurable digital out pin RF WIP/BUSY that can be
used to drive a micro controller interrupt input pin (available only when the M24LR16E-R is
correctly powered on the Vcc pin).
When configured in the RF write in progress mode (RF WIP mode), the RF WIP/BUSY pin is
driven low for the entire duration of the RF internal write operation. When configured in the
RF busy mode (RF BUSY mode), the RF WIP/BUSY pin is driven low for the entire duration
of the RF command progress.
The RF WIP/BUSY pin is an open drain output and must be connected to a pull-up resistor.
