Benefits

• ADC subsystems and peripherals tailored for

specific motor types to simplify development

• 3 Sector on-chip Flash memory allows for in-

circuit programming for software upgrade abili-

ty and rapid code development

• Integrated Power-On-Reset and precision volt

age reference reduce system costs

• Pin for pin compatible ROM device provide low

cost high volume option

Applications

• Motor types - AC Induction Motors (ACIM),

Permanent Magnet Synchronous Motors

(PMSM), Brushless DC Motors (BDCM),

Switched Reluctance Motors (SRM)

• Industrial variable speed and servo drives

• Uninterruptable power supplies

• Electric vehicles
