The C8051F852-C-IU is a 16/32-bit low-power, 8052-compatible, mixed-signal microcontroller that utilizes the powerful 8052 core, which is highly integrated with features such as a MAC Interface and bROMless internal code storage. This microcontroller includes all the features of the 8052 core, but with increased Flash (up to 128 KB) and RAM (up to 4K bytes) memory, making it ideal for applications such as higher-end 8-bit control systems. On top of that, the C8051F852-C-IU is also equipped with various I/O capabilities and perpherial functions such as two USB controllers, two Timer/Counters, eight Serial Channels, as well as various types of I/O pins and others. This part also integrates both an embedded ISP programming interface and an In-System Programming (ISP) system, providing flexibility for software development.
