Z86L87 Datasheet PDF - Zilog

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.
