PHOENIX, Arizona -- Automotive Integrated Electronics Corp., a supplier of ASIC design services and SoC chips to the automotive industry, has become a supplier of an automotive-specific microprocessor based on an ARM9-derived RISC microprocessor from ARM Holdings plc.
Oki's initial implementation of the AIEC9 microprocessor core is set to use Oki's 0.22-micron embedded flash technology and be capable of operating at 80-MHz across the automotive temperature range of --40 degrees C to 125 degrees C.
Oki's AIEC9 platform chip contains 48-kbytes of SRAM for data store and 1-Mbyte of instruction store flash with a 64-bit microprocessor interface controlled by the AIEC Memory Expander. The wide interface is used to help the AIEC9 achieve zero wait state access for sequential code despite a mismatch between CPU and flash memory maximum frequency and without use of cache memory.
