H8S/2319 | Renesas Electronics America
Its written at the top of article (Product Overview):
This LSI is a single-chip microcomputer made up of the H8S/2000 CPU with an internal 32-bit architecture as its core, and the peripheral functions required to configure a system.

High-speed H8S/2000 central processing unit with 16-bit architecture
What is correct?
