40/44/48-Pin Low-Voltage IR OTP

The Z86D73 is an OTP-based member of the MCU family of IR (infrared) micro- controllers. With 237 bytes of general-purpose RAM and 32 KB of ROM, ZiLOGs 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 Z86D73 architecture is based on ZiLOGs 8-bit Microcontroller core with an Expanded Register File to allow access to register-mapped peripherals, input/out- put (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 ancil- lary features that are useful in many consumer, automotive, computer peripheral, and battery-operated hand-held applications. There are four basic address spaces available to support a wide range of configu- rations: Program Memory, Register File, Expanded Register File, and External Memory. The Register file is composed of 256 bytes of RAM. It includes 4 I/O port Registers 16 control and status Registers and 236 general-purpose Registers The Expanded Register File consists of two additional Register groups (F and D). To unburden the program from coping with such real-time problems as generating complex waveforms or receiving and demodulating complex waveform/pulses, the Z86D73 offers a new intelligent Counter Timer architecture with 8-bit and 16-bit Counter Timers (see 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 2). By ZiLOG Semiconductor
