DACs, 12-bit PWMs, internal and external temperature
sensors, fast sample/hold, I
2
C 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 I
2
C interface. An inde-
pendent slave I
2
C 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.
