Description
The UPD78F4216A Subseries is a member of the 78K/IV Series and consists of 100-pin products intended for general-purpose applications. The 78K/IV Series has 16-bit single-chip microcontrollers and provides a high-performance CPU with functions such as access to a 1 MB memory space. The UPD78F4216A has a 128 KB mask ROM and a 8,192 bytes RAM on chip. In addition, it incorporates a high-performance timer/counter, an 8-bit A/D converter, an 8-bit D/A converter, and an independent 2-channel serial interface.The uPD784216A is based on the uPD784218A with 128 KB of mask ROM and 8,192 bytes of RAM.
