Flash MCU Is First To 90-nm

Joining the SuperH family of 32-bit microcontrollers, the SH72546RFCC debuts as the industry's first MCU with on-chip flash memory built with a 90-nm process node. It achieves a top-level operating speed of 200-MHz in temperatures up to 125°C. Also, the device's on-chip flash memory capacity, at 3.75 MB, is among the largest currently available. Its core is an enhanced superscalar design with a built-in double precision floating point unit that delivers about four times the performance of the 80-MHz SH-2E. Peripherals include a multifunction timer unit with up to 106 outputs, 37-channel 12-bit a/d converter, CAN interface, and SPI. Available development tools include the USB bus-powered E10A-USB on-chip debugging emulator that requires no external power and the E200F full-spec emulator. Available in October, packaged in a 21 mm x 21 mm P-BGA, sample price for the SH72546RFCC is $980. RENESAS TECHNOLOGY AMERICA INC., San Jose, CA. (408) 382-7407.
