DS4830
Optical Microcontroller
General Description
The DS4830 provides a complete optical control, calibra-
tion, and monitor solution based on a low-power, 16-bit,
microcontroller core, providing program and RAM data
memory. I/O resources include a fast/accurate analog-to-
digital converter (ADC), fast comparators with an internal
comparison digital-to-analog converter (DAC), 12-bit
DACs, 12-bit PWMs, internal and external temperature
sensors, fast sample/hold, I²C slave host interface, and
a multiprotocol serial master/slave interface.
Direct connection of diode-connected transistors, used
as remote temperature sensors, is supported as well as
expansion to additional external digital temperature sen-
sor ICs using the on-chip master I²C interface. An inde-
pendent slave I²C interface facilitates communication to
a host microprocessor in addition to password-protected
in-system reprogramming of the on-chip flash.
Firmware development is supported by third-party highly
versatile C-compilers and development software that
programs flash and performs in-circuit debug through
the integrated JTAG interface and associated hardware.
