Features

8-bit single chip microcomputer

TLCS-870 corios

Minimum instruction execution time: 0.5 us (at 8 MHz, gear

ratio 1/1)

129 types & 412 basic instructions

Multiplication (8 bits x 8 bits, 16 bits + 8 bits)

Execution time 3.5 us (at 8 MHz, gear ratio 1

/1))

Bit manipulations

(Set/Clear/Complement/Load/Store/Test/Exclusive or)

16-bit data operations

1-byte jump/call (Short relative jump/Vector call)

9 interrupt sources (External : 4, Internal : 5)

? All sources have independent latches each,

and nested interrupt control is available.

? Edge-selectable external interrupts with noise reject

High-speed task switching by register bank changeover

Input/Output ports (22 pins)

High current output: 6 pins (Typ.7 mA)

Two 16-bit Timer/Counters

Timer, Eventcounter, Programmable pulse generator output,

Pulse width measurement, External trigger timer,

Window modes

Time Base Timer

Interrupt frequency types : 8 types (1 to 16384 Hz)

Divider output function (frequency: 4 types)

Watchdog Timer

Two Power saving operating modes

? STOP mode : Oscillation stops. Battery/Capacitor back-up

Port output hold/high-impedance

IDLEI mode : CPU stops, and Peripherals operate using high-

frequency clock. Release by interrupts.

Operating voltage: 2.7 to 5.5 V at 4.2 MHz/1.5 to 5.5 V at 8

MHz
