Product Descriptions - Hitachi H8/300L Series Manual

The H8/3614 Series microcomputers are
general purpose 8-bit microcomputers that
include an on-chip A/D converter in a
64-pin package.
The H8/3614 Series microcomputers
integrate, around an H8/300L CPU core, a
rich set of peripheral functions, including
16, 24, and 32 kbytes of ROM, 512, 1024,
and 1024 bytes of RAM, timers, two serial
communications interfaces, an A/D
converter, and I/O ports in a 64-pin
package. They provide an optimal structure for relatively small-scale systems.
Additionally, the H8/3614 Series includes a ZTAT™ (zero turn around time) version of the
H8/3614 that allows users to freely write programs to the on-chip PROM.
