General Description

Based on the Z8 MCU single-chip family of IR microcontrollers, the Z86L81/86/98 features 237 bytes of general-purpose RAM and 24/32/64 KB of ROM. The Maxim CMOS microcontrollers offer fast executing, efficient use of memory, sophisticated interrupts, input/output bit manipulation capabilities, automated pulse generation/reception, and internal key-scan pull-up transistors.

Features

? Low power consumption–40 mW (typical)

? Three standby modes

?? – Stop—2 μA (typical)

?? – Halt—0.8 mA (typical)

– Low voltage

? Special architecture to automate both generation and reception of complex pulses or signals:

?? – One programmable 8-bit counter/timer with two capture registers and two load registers

?? – One programmable 16-bit counter/timer with one 16-bit capture register pair and one 16-bit load register pair

?? – Programmable input glitch filter for pulse reception

? Six priority interrupts

?? – Three external

?? – Two assigned to counter/timers

?? – One low-voltage detection interrupt

? Low-voltage detection with flag

? Programmable watch-dog/power-on reset circuits

? Two independent comparators with programmable interrupt polarity

? Mask selectable transistor pull-ups on ports 0, 2, 3

? Programmable mask options

?? – Oscillator selection: RC oscillator or crystal/other clock source

?? – Oscillator operational mode: normal high-frequency operation enabled or 32-KHz operation enabled

?? – Port 0: 0–3 pull-ups

?? – Port 0: 4–7 pull-ups

?? – Port 2: 0–7 pull-ups

?? – Port 3: pull-ups

?? – Port 0: 0–3 mouse mode: normal mode (.5VDD input threshold) versus mouse mode (.4VDD input threshold)
