Based on Adesto's proprietary CBRAM® technology
Description
The Adesto® RM333X Series is a 32-256Kbit, serial memory device that utilizes
Adesto's CBRAM® resistive technology.
The memory device is optimized for low power operation offering lowest available
power for data-transfer, power-down, and writing. In order to efficiently optimize power
consumption, the device makes use of two supplies VDDC, and VDDIO. The two VDDIO
supply signals must be tied together to supply write and I/O voltage (see Figure 5-2). Read
power is supplied from the VDDC and the device consumes less than10µW at
500Kbit/s.
The RM333X Series 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 read mode is 1.0MHz.

The device supports direct write eliminating the need to pre-erase. Writing into the device can be done from 1 to 32 or 64
bytes at a time and consumes less than 40uW. All writing is internally self-timed.
The device has both Byte Word Write and Page Write capability. Page Write is from 1 to 32 or 64 bytes. The 32 bit word
Write operation of CBRAM consumes only 10% of the energy consumed by a 32 bit word Write operation of EEPROM
devices of similar size.
Both random and sequential reads are available. Sequential reads are capable of reading the entire memory in one
operation.
