Architectural Overview
Zilog’s Crimzon
®
ZLR16300 MCU is a ROM-based member of the Crimzon ZLR16300
family of general-purpose microcontrollers. With 1 KB to 16 KB of Program Memory and
237 B of general-purpose RAM, Zilog’s CMOS microcontrollers offer fast-executing,
efficient use of memory, sophisticated interrupts, input/output (I/O) bit manipulation
capabilities, automated pulse generation/reception, and internal key-scan pull-up
transistors.
The Crimzon ZLR16300 architecture (see
Figure 1
on page 3 and
Figure 2
on page 4) is
based on Zilog’s 8-bit microcontroller core with an Expanded Register File allowing
access to register-mapped peripherals, I/O circuits, and powerful counter/timer circuitry.
The Z8
®
core 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 battery-operated hand-held applications.
There are three basic address spaces available to support a wide range of configurations:
1. Program Memory
2. Register File
3. Expanded Register File
The Register file is composed of 256 B of RAM. It includes three I/O port registers, 16
control and status registers, and 237 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 like generating
complex waveforms or receiving and demodulating complex waveform/pulses, the
Crimzon ZLR16300 offers a new intelligent counter/timer architecture with 8-bit and
16-bit counter/timers (see
Figure 2
on page 4). Also included are a large number of
user-selectable modes and two on-board comparators to process analog signals with
separate reference voltages.
