2. Host Interface
The micro-DRIVE (uDRIVE for short) provides both
a physical and a software interface.
2.1
The physical or hardware interface is provided by
the on-board UART and the host communicates to
the micro-DRIVE via this serial link. The host uses
this physical interface to send commands to the

Active Low pulse greater than 2 micro-seconds will reset the module.
Only use open collector type circuits to reset the device if an external
reset is required. This pin is not driven low by any internal conditions.
The host should control this pin via one of its port pins using an open
collector/drain arrangement. Internally pulled up to 3.3 Volts.
Supply Ground.
Asynchronous Serial Receive pin. Connect this pin to host micro-
controller Serial Transmit (Tx) signal. The host transmits commands and
data to the micro-DRIVE via this pin. This pin is tolerant up to 5.5V
levels.
Asynchronous Serial Transmit pin. Connect this pin to host micro-
controller Serial Receive (Rx) signal. The host receives data from micro-
DRIVE via this pin. This pin is tolerant up to 5.5V levels.
Supply input, 3.6V to 5.5V DC.

module for data storage and retrieval. Only the
serial TX, RX and GND signals are required for a
minimal configuration (see Figure 1).
2.2
The software interface provided by the uDRIVE
module is a set of easy to use serial commands.
