Description and Introduction

TLCS-Z80 PIO : PARALLEL INPUT / OUTPUT CONTROLLER The TMPZ84C20AP-8 is a Z80-compatible microprocessor manufactured by Toshiba. Below are its specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Manufacturer:** Toshiba  
- **Model:** TMPZ84C20AP-8  
- **Architecture:** Z80-compatible  
- **Clock Speed:** 8 MHz  
- **Operating Voltage:** 5V  
- **Data Bus Width:** 8-bit  
- **Address Bus Width:** 16-bit (supports up to 64KB of memory)  
- **Instruction Set:** Z80 instruction set (158 instructions)  
- **Package Type:** 40-pin DIP (Dual In-line Package)  
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C) depending on variant  

### **Descriptions:**  
- The TMPZ84C20AP-8 is a CMOS version of the Z80 microprocessor, offering lower power consumption compared to NMOS-based Z80 chips.  
- It is fully compatible with the original Zilog Z80 in terms of instruction set and pinout.  
- Designed for embedded systems, industrial control, and consumer electronics applications.  

### **Features:**  
- **Low Power Consumption:** CMOS technology reduces power usage.  
- **High-Speed Operation:** 8 MHz clock speed for efficient processing.  
- **On-Chip Registers:** Includes general-purpose registers, accumulators, and index registers.  
- **Interrupt Support:** Supports maskable, non-maskable, and vectored interrupts.  
- **Built-in DRAM Refresh:** Simplifies memory interfacing.  
- **Single 5V Power Supply:** Compatible with standard TTL logic levels.  

This information is based solely on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

TLCS-Z80 PIO : PARALLEL INPUT / OUTPUT CONTROLLER

Alternative Part Number

  • Z84C2008PEG --: Zilog Z84C20 parallel I/O controller in 40-pin DIP at 8 MHz, functionally equivalent to the Toshiba TMPZ84C20AP-8.
  • Z84C2010PEG --: Same Z84C20 PIO family in DIP package; 10 MHz rating covers the 8 MHz requirement with margin.
  • Z84C2006PEG --: Lower 6 MHz speed grade of the same Z84C20 PIO; usable if the system timing allows a slower clock.
  • Z84C2008PEC --: Zilog Z84C20 parallel I/O controller, 8 MHz CMOS version, functionally equivalent to the Toshiba TMPZ84C20AP-8 and pin-compatible in most designs.
  • Z84C2010PEC --: 10 MHz rated Z84C20 PIO that exceeds the 8 MHz requirement, offering margin and drop-in compatibility for the original Toshiba part.
