An 8-bit single-chip microcontroller is a type of microcontroller that has an 8-bit central processing unit (CPU) architecture integrated onto a single chip. It combines various components, including CPU, RAM, ROM or flash memory, input/output (I/O) ports, timers, and sometimes other peripherals, all within a single IC (integrated circuit).

Description
D789188CT is 8-BIT SINGLE-CHIP MICROCONTROLLER. The central processing unit is the core of the microcontroller, and in this case, it has an 8-bit architecture. This means that the CPU can process data in 8-bit chunks, which limits the size of data it can handle at once but simplifies the instruction set and reduces the complexity of the microcontroller.
This is NEW Subseries (small, general-purpose) in the 78K/0S Series. The µPD78F9189 replaces the internal ROM of the µPD789188 with flash memory. Because flash memory allows the program to be written and erased electrically with the device mounted on the board, this product is ideal for the evolution stages of system development, small-scale production and rapid development of new products. Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before designing. µPD789167, 789177, 789167Y, 789177Y Subseries User’s Manual: U14186E 78K/0S Series User’s Manual Instruction: U11047E
