The MR25H nonvolatile serial MRAM memory family includes 256-Kbyte, 512-Kbyte, and 1-Mbyte devices. The devices require no write delay, clock speeds as fast as 40 MHz, and have essentially unlimited endurance plus more than 20 years of data retention.
The ICs use a standard SPI interface, operate from 2.7 to 3.6 V, and have 3 uA typ sleep-mode current. They come in low-profile 8-pin DFN standard packages and 0° to 70°C and 40° to 85°C operating temperature ranges. (MR25H10 1-Mbyte version, $3.10 ea/100,000 available now.)
