Built-in motor automatic control (PID) and an expansion PWM are suitable for lenses of camera

32-bit microcomputer for a camera lens with an image stabilizer
MN103SFH6K

Overview

MN103SFH6K  MN103SFH6K is a 32-bit microcomputer with Panasonic's original 32-bit CPU “AM32” built-in, featuring saving code size, high performance and low power consumption. This microcomputer achieves the high-efficiency and performance lens control and system control by a single microcomputer control for a camera lens with an image stabilizer by built-in high-speed arithmetic unit, expansion PWM and motor automatic control (PID) for PWM output function.

Features

  • Achieving high performance by adopting various extended arithmetic circuits
  • Built-in expansion PWM output function enables various motor controls
  • Built-in PID control makes image stabilizer performance better and significantly reduces CPU's processing load at the same time
  • Built-in 10bit A/D × 2unit (conversion speed : 1.3µs)
  • Built-in 8bit D/A × 6unit enables offset arrangement of various external amplifier
  • Built-in high-speed oscillation circuit makes microcomputer's high-speed boot

Applications

  • For a camera lens with an image stabilizer control
