Architectural Overview
Zilog’s Crimzon
®
ZLP32300 is an OTP-based member of the MCU family of infrared
microcontrollers. With 237 B of general-purpose RAM and 8 KB 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 Crimzon ZLP32300 architecture (see
Figure 1
on page 3) is based on Zilog’s 8-bit
microcontroller core with an Expanded Register File allowing access to register-mapped
peripherals, input/output (I/O) circuits, and powerful counter/timer circuitry. The Z8
®
CPU 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 Bytes of RAM. It includes four 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
Crimzon ZLP32300 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.
Note:
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.
Power connections use the conventional descriptions listed in
Table 1.
