The S87C752-5A28 is a potent single-chip microcontroller designed by Philips (now NXP/Philips), based on the high-performance 8051 architecture. Operating at a clock frequency of up to 30 MHz, it provides a robust set of features including 2 KB of on-chip EPROM, 128 bytes of RAM, 32 I/O lines, two 16-bit timer/counters, a six-source, four-priority level nested interrupt structure, an eight-bit A/D converter with multiple channels, and a serial communication interface supporting multiple modes. This integration facilitates the development of highly efficient and compact system-level designs in a wide range of applications, from automotive control systems and portable devices to industrial automation and consumer electronics. The compatibility with the 8051 instruction set ensures ease of development and migration of existing firmware bases. The S87C752-5A28's low power consumption, combined with its enhanced processing speed and peripheral set, makes it an excellent choice for designers looking to leverage the power of the 8051 architecture in modern applications requiring compactness, efficiency, and reliability.
