Z86L8108HSG Datasheet

28-Pin Low-Voltage Infrared Microcontrollers


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.

• 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)
