SECTION 1 – OVERVIEW
The DS4830 System Management Microcontroller provides a complete optical control, calibration, and monitor solution.
The IC is based on the high-performance 16-bit family of MAXQ
®
reduced instruction set computing (RISC)
microcontrollers, and provides generous amounts of flash program memory and SRAM data memory.
Some of the resources and features that the DS4830 provides for monitoring and controlling an optical system include the
following:
