ST adds DSP core to FPGA-enabled wireless controller

Posted: 08 Jun 2005 ?? ?Print Version ?Bookmark and Share


STMicroelectronics NV has said it has an enhanced version of its recently announced STW21000, a multi-purpose microcontroller that includes an FPGA array that targets applications in wireless infrastructure equipment.

Fabricated using ST's 130nm CMOS technology, the new device, dubbed the STW22000, adds a 600MHz clock frequency dual-MAC DSP core to the existing device, which already integrates a 300MHz ARM926EJ-S RISC processor, 16-Mbits of embedded DRAM, as well as the embedded Field-Programmable Gate Array block, reconfigurable interfaces, and a range of analog and digital peripherals such as A/D and D/A converters.

The original STW21000 device was announced in March 2005.
