DS4830

DS4830 Optical Microcontroller General Description The DS4830 provides a complete optical control, calibration, 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-todigital 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 sensor ICs using the on-chip master I2C interface. An independent 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.
