  • Architectural Overview

    The Z86L972/Z86L973/Z86L974 family is designed to be used in a wide variety of embedded control applications including home appliances, infrared (IR) remote controls, security systems, and wireless keyboards.

    Features
    • Two independent analog comparators
    • Controlled current output
    • 489 bytes of RAM
    – 233 bytes of general-purpose register-based RAM
    – 256 bytes of RAM mapped into the program memory space that can be
    used as data RAM or executable RAM
    • 4K/8K/16K bytes of ROM

    Counter/Timers
    • Special architecture to automate generation and reception of complex pulses
    or signals:
    – Programmable 8-bit counter/timer (T8) with two 8-bit capture registers and
    two 8-bit load registers
    – Programmable 16-bit counter/timer (T16) with one 16-bit capture register
    pair and one 16-bit load register pair
    – Programmable input glitch filter for pulse reception
    • One general-purpose 8-bit counter/timer (T1) with 6-bit prescaler

    Input/Output and Interrupts
    • Thirty-two I/Os, twenty-nine of which are bidirectional I/Os with programmable
    resistive pull-up transistors (24 I/Os are available in the 28-pin configuration)
    • Sixteen I/Os are selectable as stop-mode recovery sources
    • Six interrupt vectors with nine interrupt sources
    – Three external sources
    – Two comparator interrupts
    – Three timer interrupts
    – One low-battery detector flag

    Operating Characteristics
    • 8-MHz operation
    • 2.3 V to 5.5 V operating voltage
    • Low power consumption with three standby modes:
    – Stop
    – Halt
    – Low Voltage Standby
    • Low-battery detection flag
    • Low-voltage protection circuit (also known as VBO, or voltage brownout,
    circuit)
    • Watch-dog timer and power-on reset circuits

    User-Programmable Option Bits
    • Clock source—RC/other (LC, resonator, or crystal)
    • Watch-dog timer permanently enable
    • 32-kHz crystal
    • Port 20–27 pull-up resistive transistor
    • Port 40–42 pull-up resistive transistor
    • Port 44–47 pull-up resistive transistor
    • Port 50–51 pull-up resistive transistor
    • Port 54–57 pull-up resistive transistor
    • Port 60–63 pull-up resistive transistor
    • Port 64–67 pull-up resistive transistor
