0.18?m embedded flash suits power-sensitive apps

Taiwan Semiconductor Manufacturing Co. Ltd has qualified its new 0.18?m embedded flash (embFlash) process technology family that targets a wide range of applications. The new family includes a baseline 1.8V to 5V standard process, an ultra-low leakage process and specific automotive-qualified embedded Flash IP.

"This extended featured-rich 0.18?m embedded flash family demonstrates the emphasis that #LINKKEYWORD0# places on serving the analog, power sensitive and automotive markets. The breadth of applications that this family targets is unprecedented and reflects the growing market demand for technology that is both broad in scope, yet precise in its application," said George Liu, director of mainstream technology business.

The baseline 0.18?m 1.8V/5V embFlash process supports enhanced analog performance and traditional 5V I/O interface applications. The true 5V I/Os achieve better performance in a smaller footprint than similar 5V I/Os built on higher voltage devices. The process features a single low voltage flash IP that operates fully functions at 1.8V. Several flash IP macros and a customization service are available now. The new process is ideal for large appliance motor controls on refrigerators, washing machines and air conditioners.

The TSMC 0.18?m Ultra-Low-Leakage (uLL) embFlash process operates at 1.8V and features a 95 percent leakage reduction compared to the baseline process. Built upon the uLL devices, CPU, standard cell library and SRAM can save up to 85 percent, 90 percent and 95 percent standby current respectively, compared to the baseline process. A low-power flash IP supports up to 80 percent lower standby current and 60 percent lower active current with the flash IP compiler expected to be available in Q3 09. The uLL process is particularly suitable for power-sensitive and portable devices. The High-Data-Retention member of the 0.18?m embedded flash family operates at 1.8V/3.3V and has been qualified for automotive quality requirement AEC-Q100. Extensive test methodology has also been developed to meet the stringent automotive ppm requirements in powertrain, security systems, body systems and infotainment. The TSMC's 0.18?m process requires only seven mask layers to implement the embedded flash features and is now ready for production in Fab 3.
