GENERAL DESCRIPTION

The Z86L7X family of IR (Infrared)/Low-Voltage Microcontrollers are ROM/ROMless-based members of the Z8® MCU single-chip family with 237/125 bytes of internal RAM. The differentiating factor between these devices is the availability of RAM, ROM and package options. Offering the 3V versions (Z86LXX) with the Z86C71 gives optimum performance in both the low and high voltage ranges
