R8A77940DB20BG is a Microcontroller Unit (MCU) within an FBGA package. Considered within the category of an embedded processor and microcontrollers. MCU is an integrated circuit that comprises a variety of memory modules, communication interfaces, and peripherals. MCU is capable of performing the arithmetic operations on binary values. In technical terms, MCU can perform according to the instruction set. Most of the MCU's are Reduced instruction Set Computer (RSIC) R8A77940DB20BG is a 32 Bit MCU, with SuperH or SH architecture launched by the Renesas. SuperH is a 32-bit RSIC that was introduced by Hitachi and has been re-developed by Renesas. R8A77940DB20BG is ROM less module, requiring a 3.3 V voltage supply, and 449 pins in a fine ball grid array (FBGA). The module is designed to operate with tray packaging. The package information is mentioned on the datasheet. Some other features of the modules are the availability of Power-on reset (POR), Direct memory ac...
