H8 Family: Applications, Technology & Products

The Hitachi H8 is a large family of 8-bit, 16-bit and 32-bit microcontrollers made by Renesas Technology, originating in the early 1990s within Hitachi Semiconductor. The original design, the H8/300, was an 8-bit processor that had 16-bit registers and ALU which allowed some 16-bit operations. Two upgraded versions were introduced, the H8/300L that…
