The Intel C8751H-88 is a variant of the C8751H 8-bit microcontroller, part of the MCS-51 family. As a single-chip microcontroller, it integrates EPROM, RAM, I/O ports, timers, and serial communication capabilities. The 'C' prefix indicates CMOS technology for lower power consumption. The '-88' suffix likely signifies a specific speed grade, production batch, or a slight variation in its characteristics compared to the standard C8751H.

Applications:

• Embedded control systems
• Industrial automation
• Robotics
• Consumer electronics
• Automotive applications

Features:

• 8-bit CPU
• 4 KB on-chip EPROM
• 128 bytes on-chip RAM
• 32 programmable I/O lines
• Two 16-bit timer/counters
• Full duplex UART serial channel
• Six interrupt sources

Benefits:

• Integrated single-chip solution reducing external components
• Lower power consumption due to CMOS technology
• Easy programming with various development tools
• Flexible I/O for interfacing with peripherals
• Suitable for a wide range of control applications

Additional Details:

The C8751H-88, like its C8751H counterpart, typically operates with a clock frequency up to 12 MHz. It offers various addressing modes for efficient memory and peripheral access. The 32 I/O lines are configurable as inputs or outputs for versatile interfacing. The 16-bit timer/counters can be used for timing, counting, and PWM signal generation. The UART serial channel facilitates serial communication using protocols like RS-232. It has six interrupt sources to handle real-time events. The '-88' likely indicates a specific manufacturing process or performance characteristic, potentially related to its operating temperature range, speed grade, or power consumption compared to the standard C8751H. However, the core functionality and architecture remain similar to the C8751H. It is commonly packaged in a 40-pin DIP (Dual In-line Package) and is used in diverse embedded control applications.
