General Description The Z86L82/85/88 are ROM-based members of the Z8 MCU single-chip family of infrared (IR) controllers, featuring 237 bytes of general-purpose RAM and 4/8/16 KB of ROM, respectively. ZiLOG’s 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. The Z86L8X architecture is based on ZiLOG's 8-bit microcontroller core featuring an Expanded Register File to allow access to register-mapped peripherals, I/O circuits, and powerful counter/timer circuitry. The Z8 offers a flexible I/O scheme, an efficient register and address-space structure, and a number of ancillary features that are useful in many consumer, automotive, computer peripheral, and batteryoperated hand-held applications. Three basic address spaces are available to support a wide range of configurations: program memory, register file, and Expanded Register File. The register file consists of 256 bytes of RAM. It includes 4 I/O port registers, 16 control and status registers, and 236 general-purpose registers. [Register FEh (SPH) can be used as a general-purpose register.] The Expanded Register File consists of two additional register groups (F and D). The Z86L8X offers a new intelligent counter/timer architecture with 8-bit and 16-bit counter/timers (Figure 1). Also included are a large number of user-selectable modes and two on-board comparators to process analog signals with separate reference voltages (see Figure 9 on page 18).

Ambient Temperature † C Notes: * Voltage on all pins with respect to GND † See “Ordering Information” on page 69. Stresses greater than those listed under Absolute Maximum Ratings might cause permanent damage to the device. This rating is a stress rating only. Functional operation of the device at any condition above those indicated in the operational sections of these specifications is not implied. Exposure to absolute maximum rating conditions for an extended period might affect device reliability.
