Technical information

The 38K0 Group is specialized for Bulk
application with a small package.
It is suitable for one-chip USB converter with
built-in serial I/O or bus interface.
The 38K0 Group consists of 8-bit single-chip MCUs with
built-in USB functions in compliance with Full-Speed
USB2.0. The built-in 4 endpoints, external bus interface×1,
serial I/O×1, 8-bit timer×3 and A/D converter (8-channel)
enable a variety of USB functions. In addition, 38K0 Group
MCUs are suitable for USB conversion devices since the
internal RAM can be accessed directly from USB and
external interfaces.

38K0 Group
Compound USB Hub of Hub + function
Abundant peripheral functions are embedded to
realize Hub + function application equipment
with one chip.
The 38K2 Group consists of 8-bit single-chip MCUs with
built-in USB Hub + USB functions in compliance with
Full-Speed USB2.0. The built-in down stream ports×2, 6
endpoints (USB functions: 4, USB Hub: 2), external bus
interface×1, serial I/O×1, 8-bit timer×3 and A/D converter
(8-channel) enable a variety of USB Hub + USB functions.
In addition, 38K2 Group MCUs are suitable for USB
conversion devices since the internal RAM can be
accessed directly from USB and external interface.
