PARIS Ė STMicroelectronics NV has unveiled a new version of its 32-bit ARM9-based STR910F Flash microcontroller family that is claimed to deliver 25 percent greater system performance.
ST said it has added six members to the STR910 family with Ethernet, USB and CAN interfaces as well as on-chip SRAM up to 96Kbytes and Flash memory up to 544Kbytes.
Autobench test suite from Embedded Microprocessor Benchmark Consortium (EEMBC) indicated that the STR910FA registered "an average of 25 percent better than those of the STR910F, indicating improved overall system performance due to improved flow of instructions to the CPU."
According to EEMBC, the STR910FA also registered an average performance gain of 36 percent over competing Flash ARM7-based MCUs for the same Autobench tests.
Prices for ST's new STR910F microcontroller series start at $4.98 in quantities of 10,000. All devices operate between -40 to +85 degrees C, ST concluded.
