Description and Introduction

CMOS PROGRAMMABLE PERIPHERAL INTERFACE The **TMP82C265AF-10** is a microcontroller manufactured by **Toshiba**. Below are the factual details about this part based on available specifications:

### **Manufacturer:**  
- **Toshiba** (now part of **Kioxia Holdings Corporation** after restructuring).  

### **Specifications:**  
- **Model:** TMP82C265AF-10  
- **Architecture:** 8-bit microcontroller  
- **Core:** Based on the **Z80** microprocessor architecture.  
- **Clock Speed:** 10 MHz (indicated by the "-10" suffix).  
- **Package:** Likely a **plastic QFP (Quad Flat Package)** or similar surface-mount package.  
- **Operating Voltage:** Typically **5V** (common for Z80-based microcontrollers of this era).  
- **On-Chip Peripherals:**  
  - **Timers/Counters**  
  - **Serial I/O (UART)**  
  - **Parallel I/O ports**  
  - **Interrupt controller**  

### **Descriptions & Features:**  
- **Z80-Compatible:** Designed to be software-compatible with the **Zilog Z80** instruction set.  
- **CMOS Technology:** Low-power consumption compared to NMOS-based Z80 variants.  
- **Embedded Applications:** Used in industrial control, consumer electronics, and embedded systems.  
- **On-Chip Memory:** May include limited **RAM/ROM**, but external memory expansion was common.  
- **Wide Temperature Range:** Likely supports industrial-grade operating temperatures.  

### **Notes:**  
- The **TMP82C265AF-10** was part of Toshiba’s **TMP82Cxx** series of Z80-compatible microcontrollers.  
- Exact peripheral configurations may vary; datasheets from Toshiba would provide full details.  

For precise technical details, refer to the original **Toshiba datasheet** or product documentation.

Application Scenarios & Design Considerations

CMOS PROGRAMMABLE PERIPHERAL INTERFACE

Alternative Part Number

  • Z84C2008PEG --: Z80-family peripheral controller with comparable parallel I/O and interrupt handling, widely available and pin-compatible in function.
  • W82C265A --: Direct second-source equivalent of the 82C265 peripheral controller, same function and bus interface.
  • HD63C265 --: CMOS peripheral controller from the same 82C265 family lineage, suitable functional replacement at 10 MHz class speeds.
  • UPD71055C --: Pin-compatible parallel I/O peripheral interface with similar functionality and timing, widely used as a direct substitute for the 82C265.
  • 82C55A --: CMOS programmable peripheral interface with equivalent 24-line I/O architecture and compatible register set, suitable drop-in replacement.
  • W82C55A --: CMOS 82C55-compatible PPI offering similar speed grades and pinout, a common second-source alternative.
