6.1
The H8/3832 has 16 kbytes of on-chip ROM, while the H8/3833 has 24 kbytes, the H8/3834 has
32 kbytes, the H8/3835 has 40 kbytes, the H8/3836 has 48 kbytes, and the H8/3837 has 60 kbytes.
The ROM is connected to the CPU by a 16-bit data bus, allowing high-speed 2-state access for
both byte data and word data. The ZTAT™ versions of the H8/3834 and H8/3837 each have 32
kbytes and 60 kbytes of PROM.
With regard to ZTAT versions of the H8/3832S, H8/3833S, H8/3834S, H8/3835S, H8/3836S, and
H8/3837S, the ZTAT versions of the H8/3834 and H8/3837 should be used.
