The memory devices use a single low-voltage supply ranging from 1.65V to 3.6V. 2 2 The MavriqI C device is accessed through a 2-wire I C compatible interface consisting of a Serial Data (SDA) and Serial Clock (SCL). The maximum clock (SCL) frequency is 1MHz. The devices have both byte write and page write capability. Page DS-RM24C512C-L082E11/2016write 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. Adesto s EEPROM endurance can be as much as 40X higher than industry standard EEPROM devices operating in byte write mode at 85C. 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 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, UDFN and WLCSP packages. RM24C512C-L 2 DS-RM24C512C-L082E11/2016
