Architectural Overview

Note:
Zilog’s ZGP323H is an OTP-based member of the MCU family of infrared
microcontrollers. With 237 B of general-purpose RAM and up to 32 KB of OTP, 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 ZGP323H architecture (see
with an Expanded Register File allowing access to register-mapped peripherals, input/
output (I/O) circuits, and powerful counter/timer circuitry. The Z8
scheme, an efficient register and address space structure, and a number of ancillary
features that are useful in many consumer, automotive, computer peripheral, and battery-
operated hand-held applications.
There are three basic address spaces available to support a wide range of configurations:
Program Memory, Register File and Expanded Register File. 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, Z8 GP
OTP offers a new intelligent counter/timer architecture with 8-bit and 16-bit counter/
timers (see
on-board comparators to process analog signals with separate reference voltages.
All signals with an overline, “ ”, are active Low. For example, B/W, in which WORD is
active Low, and B/W, in which BYTE is active Low.
