Description
The MavriqRM24EP32C is an EEPROM-compatible, sterilization-tolerant 32Kbit
non-volatile serial memory utilizing Adesto's CBRAM resistive memory technology.
The memory devices use a single low-voltage supply ranging from 2.7V to 3.6V. The
Adesto® I2C device is accessed through a 2-wire I2C compatible interface consisting of
a Serial Data (SDA) and Serial Clock (SCL). The maximum clock (SCL) frequency is
400 KHz. The devices have both byte write and page write capability. Page write is up
to 32 bytes. The Byte Write operation of Mavriq serial memory consumes only 10% of
the energy consumed by a Byte Write operation of EEPROM devices of similar size.
The Page Write operation of Mavriq memory is 4-6 times faster than the Page Write
operation of similar EEPROM devices. Both random and sequential reads are
available. Sequential reads are capable of reading the entire memory in one
operation. External address pins permit up to eight devices on the same data bus. The
devices are available in standard 8-pin SOIC and TSSOP packages.

Description
LSB of the three external enable bits (E0, E1 and E2). The levels of
the external enable bits are compared with three enable bits in the
received control byte to provide device selection. The device is
selected if the comparison is true. Up to eight devices may be
connected to the same bus by using different E0, E1, E2
combinations.
The middle of the three external enable bits (E0, E1 and E2). The
levels of the enable bits are compared with three enable bits in the
received control byte to provide device selection. Also see the E0,
E2 pin.
MSB of the three external enable bits (E0, E1 and E2). The levels
of the enable bits are compared with three enable bits in the
received control byte to provide device selection. Also see the E0,
E1 pin.
Bidirectional pin used to transfer addresses and data into and data
out of the device. It is an open-drain terminal, and therefore
requires a pull-up resistor to VCC. Typical pull-up resistors are:
10KΩ for 100KHz, and 2KΩ for 400KHz.
For normal data transfer, SDA is allowed to change only during SCL
low. Changes during SCL high are reserved for indicating the
START and STOP conditions.
This input is used to synchronize the data transfer from and to the
device. SCL is an input only, since it is a slave-only device.
Connect to either VCC or GND. If pulled low, write operations are
enabled. If pulled high, write operations are inhibited, but read
operations are not affected.
