INTRODUCTION
The UT80CRH196KD is compatible with industry standard’s
MCS-96 instruction set. The UT80CRH196KD is supported
by commercial hardware and software development tools.
Built on UTMC’s Commercial RadHard
TM
epitaxial CMOS
technology, the microcontroller is hardened against ionizing
dose and charged particles. The microcontroller’s on-board
1000 byte scratch-pad SRAM and flip-flops can withstand
charged particles with energies up to 25 MeV-cm
2
/mg.
The UT80CRH196KD accesses instruction code and data via
a 16-bit address and data bus. The 16-bit bus allows the
microcontroller to access 128K bytes of instruction/data
memory. Integrated software and hardware timers, high speed
I/O, pulse width modulation circuitry, and UART make the
UT80CRH196KD ideal for control type applications. The
CPU’s ALU supports byte and word adds and subtracts, 8 and
16 bit multiplies, 32/16 and 16/8 bit divides, as well as
increment, decrement, negate, compare, and logical
operations. The UT80CRH196KD’s interrupt controller
prioritizes and vectors 18 interrupt events. Interrupts include
normal interrupts and special interrupts. To reduce power
consumption, the microcontroller supports software invoked
idle and power down modes. The UT80CRH196KD is
packaged in a 68-lead quad flatpack.
