FRANKFURT, Germany -- Fujitsu Ltd's European Microcontroller Design Centre here today announced a new CAN microcontroller offering that combines a Full-CAN bus interface and on-chip flash memory at a low cost.
Aimed at automotive and industrial embedded control applications, the MB90F497 is designed to compete against low-cost products that offer only a basic CAN interface and 8-bit architecture.
The MB90F497 is based on Fujitsu's F2MC-LX 16-bit microprocessor core and CAN bus macro. A Full-CAN bus interface, conforming to V2.0 part A and part B is combined with on-board 64 kilobytes of single-voltage flash as user-programmable memory. A flexible message-buffer scheme using eight buffers offers increased functionality over traditional CAN designs, the company said.
A system clock employing an on-chip phase-lock-loop (PLL) clock multiplier provides an internal instruction cycle time of 62.5-nanosseconds from an external 4-MHz clock. A 32-kHz subsystem clock is also available for additional power saving modes and real time measurement. The chip has 10 different power saving modes, including sleep, stop, CPU intermittent mode, and hardware standby pin.
Fujitsu said it plans to price the MB90F497 competitively in order to serve both high-end 8-bit and entry-level 16-bit applications..
Fabricated in 0.5-micron CMOS technology and housed in a QFP-64, 0.65-mm pin-pitch package, the new chip will be available in sampling quantities during the first quarter of 2000, with production volumes scheduled for the second quarter.
