Z86L79 - Low-Voltage Microcontroller

Datasheet Summary

Description

The Z86L79/L80 family of IR (InfraRed) Controllers are ROM-based members of the Z8® MCU single-chip microcontroller family with 237 bytes of general-purpose RAM.

The only differentiating factor between these two versions is the availability of ROM.

Features

  • Part Z86L79 Z86L80 ROM (KB) 4 8 RAM.
  • (Bytes) 237 237 s 1 Five Priority Interrupts Low Voltage Detection and Standby Mode Watch-Dog/Power-On Reset Circuits Two Independent Comparators with Programmable Interrupt Polarity On-Chip Oscillator that Accepts a Crystal, Ceramic Resonator, LC, RC, or External Clock Drive Mask Selectable 200 kOhm Pull-Ups on Ports 0, 2, 3.
  • All Eight Port 2 Bits at One Time or Not.
  • Pull-Ups Automatically Disabled Upon Selecting Individual Pins as Ou.
