Based on Adesto's proprietary CBRAM® technology
The MavriqRM25C512C-L is a 512 Kbit, serial EEPROM device that utilizes
Adesto's CBRAM® resistive memory technology. The memory devices use a single
low-voltage supply ranging from 1.65V to 3.6V.
The Mavriq RM25C Series family is accessed through a 4-wire SPI interface
consisting of a Serial Data Input (SDI), Serial Data Output (SDO), Serial Clock (SCK),
and Chip Select (CS). The maximum clock (SCK) frequency in normal read mode is
1.6MHz. In fast read mode the maximum clock frequency is 20MHz.

Writing into the device can be done from 1 to 128 bytes at a time. All writing is internally self-timed. The device also
features an Erase which can be performed on 128 byte pages or on the whole chip.
Adesto's EEPROM endurance can be as much as 40X higher than industry standard EEPROM devices operating in byte
write mode at 85°C. Unlike EEPROMs based on floating gate technology (which require read-modify-write on a whole
page for every write operation) CBRAM write endurance is based on the capability to write each byte individually,
irrespective of whether the user writes single bytes or an entire page. Additionally, unlike floating gate technology,
CBRAM does not experience any degradation of endurance across the full temperature range. By contrast, in order to
modify a single byte, most EEPROMs modify and write full pages of 32, 64 or 128 bytes. This provides significantly less
endurance for floating gate devices used in byte write mode when compared to page write mode.
The device has both Byte Write and Page Write capability. Page Write is 128 bytes. The Byte Write operation of Mavriq
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.
