The FM24C16A is a 16-kilobit nonvolatile memory employing an advanced ferroelectric process. It provides reliable data retention for over 45 years while eliminating the complexities, overhead, and system level reliability problems caused by EEPROM and other nonvolatile memories. Unlike serial EEPROMs, the FM24C16A performs write operations at bus speed. No write delays are incurred. The next bus cycle may commence immediately without the need for data polling. The FM24C16A is also available in an 8-pin SOIC (-S) package and a "Green" 8-pin SOIC (-G) package.

The FM24CL64 is a 64-kilobit nonvolatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or FRAM is nonvolatile and performs reads and writes like a RAM. It provides reliable data retention for 45 years while eliminating the complexities, overhead, and system level reliability problems caused by EEPROM and other nonvolatile memories. The FM24CL64 performs write operations at bus speed. No write delays are incurred. The next bus cycle may commence immediately without affecting data retention.

FM1608 is a 64-kilobit nonvolatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or FRAM is nonvolatile but operates in other respects as a RAM. It provides data retention for 45 years while eliminating the reliability concerns, functional disadvantages and system design complexities of battery-backed SRAM. Its fast write and high write endurance make it suitable for automotive electronics, consumer electronics and industrial applications.

The VRS51x540 is a low-cost 8-bit microcontroller based on the standard 80C51 microcontroller family architecture. It is pin compatible and can be used as a drop-in replacement for standard 8051 MCUs. The product is aimed at cost-effective applications requiring small amounts of program/data memory coupled with streamlined peripheral support. The VRS51x540 includes 4KB of Flash memory, 128 bytes of RAM, a UART, three 16-bit timers, a Watchdog timer, and power down features. The VRS51x540 is available in 5V (VRS51C540) and 3.3V (VRS51L540) versions in PLCC-44, QFP-44, and DIP-40 packages. The devices operate over the entire industrial temperature range. The Flash memory can be programmed using programmers available from Ramtron or other third-party commercial programmers.
