Status
Active: In Production.
Description
The DS4830 provides a complete optical control, calibration, and monitor solution with a low-power, 16-bit, MAXQ20 microcontroller core providing generous 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 a virtually unlimited number of 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.
Ease of development is supported with highly versatile C-compilers and development software that programs flash and performs in-circuit debug through the integrated JTAG interface and associated hardware.
