Z86L8708FSC

IR/Low-voltage microcontroller. 8MHz, 16 KB ROM, 236 bytes RAM, I/O 31, 2V to 3.9V

GENERAL DESCRIPTION

The Z86LXX family of IR Infrared CCP™ 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 pack age 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.
