Crimzon® ZLP32300

Product Specification

PS020823-0208

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.

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.
