Prevents internal

to I/O pins.
Prevents noise
propagation.
Enables power supply
decoupling and current
loop minimization.
Separate power supplies are used for internal
logic and I/O.
Internal EMI noise can be prevented from
propagating to I/O pins.
Oscillator pins are guarded by GND pins.
Spurious noise from oscillator pins can be
suppressed.
Spike noise can be eliminated.High-frequency noise can be eliminated by
placing a noise filter.
A decoupling capacitor is attached to the noise source.
High-frequency currents directly flowing to
power supply lines can be reduced.
Spurious noise can be suppressed by minimizing
current loops created by circuit operations.

The core architecture is configured to reduce the number of clock cycles
required to complete one machine cycle to a single clock cycle. This achieves
processing performance four times that of TLCS-870/C Series at the same
internal clock frequency.
