The Z86LXX family of IR (Infrared) CCPTM (Consumer Controller Processor) Controllers are ROM/ROMless-based members of the Z8 single-chip microcontroller family with 256 bytes of internal RAM. The differentiating factor between these devices is the availability of ROM, and package options. For the 40 and 44-pin devices the use of external memory enables these Z8 microcontrollers to be used where code flexibility is required. Zilog's CMOS microcontrollers offers fast executing, efficient use of memory, sophisticated interrupts, input/output bit manipulation capabilities, automated pulse generation/reception, and inDS96LV00800
