TI has has announced their MSP430FR57xx ultra-low-power ferroelectric random access memory (FRAM) line of 16-bit microcontrollers. Their stated benefits are the ability to write data more than 100 times faster with power consumption of 250 times less than flash- and EEPROM-based microcontrollers. They are also code compatible with other MSP platforms.
The on-chip FRAM allows data retention in all power modes, supports more than 100 trillion write cycles, and delivers a new dimension of flexibility by allowing developers to partition data and programming memory with changes in software.
These chips come in several package types, including TSSOP and VQFN, and TI states samples are available. You can check the listing of chips and their specs here.
TI is taking advance orders for the $29 MSP-EXP430FR5739 Experimenter Board, which is a development platform for the MSP430FR57xx devices.
