Description and Introduction

CMOS 8-BIT MICROCONTROLLER The TMP87CM70AF is a microcontroller manufactured by Toshiba. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Toshiba  
- **Core:** 8-bit  
- **Architecture:** CMOS  
- **ROM Size:** 16KB (Mask ROM)  
- **RAM Size:** 512 bytes  
- **Operating Voltage:** 2.7V to 5.5V  
- **Clock Frequency:** Up to 8MHz  
- **I/O Ports:** 40 pins (including input/output ports)  
- **Timers:** Multiple built-in timers (e.g., 8-bit timer, watchdog timer)  
- **Interrupts:** Multiple interrupt sources  
- **A/D Converter:** None (purely digital)  
- **Package:** 42-pin SDIP (Shrink Dual In-line Package)  

### **Descriptions:**  
The TMP87CM70AF is an 8-bit microcontroller designed for embedded control applications. It features a Toshiba-proprietary CPU core optimized for low-power operation and efficient processing. It includes built-in ROM and RAM, making it suitable for fixed-function applications where program memory does not need modification.  

### **Features:**  
- **Low Power Consumption:** Operates efficiently within a wide voltage range (2.7V–5.5V).  
- **High-Speed Processing:** Capable of running at up to 8MHz clock speed.  
- **Integrated Peripherals:** Includes timers and I/O ports for embedded control tasks.  
- **Compact Package:** 42-pin SDIP form factor for space-constrained designs.  
- **Mask ROM:** Pre-programmed ROM for cost-effective mass production.  

This microcontroller is commonly used in consumer electronics, industrial control systems, and other embedded applications requiring reliable 8-bit processing.

Application Scenarios & Design Considerations

CMOS 8-BIT MICROCONTROLLER

Alternative Part Number

  • UPD78F0034AGC-8EU --: 8-bit microcontroller with comparable 8-bit CPU core, on-chip flash and similar peripheral set; Renesas (formerly NEC) is a direct second source for Toshiba 8-bit MCUs in appliance and industrial designs.
  • PIC16F877A-I/P --: Widely available 8-bit flash microcontroller with comparable I/O, timers, ADC and serial interfaces; suitable functional replacement when firmware is recompiled.
  • AT89C51RC-24PU --: Classic 8051-core 8-bit microcontroller with similar pin count and peripheral mix; low-cost, long-life alternative for legacy Toshiba 8-bit MCU sockets.
