DESCRIPTION
The
μ
PD78058F(A) is an 8-bit single-chip microcontroller belonging to the
μ
PD78058F Subseries of the 78K/0
Series. A stricter quality assurance program is applied to this device, which is classified as special grade, compared
to the
μ
PD78058F, which is classified as standard grade.
The Electro Magnetic Interference (EMI) noise generated inside the
μ
PD78058F(A) is reduced compared to the
μ
PD78058 Subseries.
This microcontroller includes a rich assortment of peripheral hardware, such as 8-bit resolution A/D converter, 8-
bit resolution D/A converter, timer, serial interface, real-time output port, and interrupt functions.
The
μ
PD78P058F, a one-time PROM version which can be operated in the same supply voltage range as the mask
ROM version, and various development tools are also available.
Details of the function descriptions are described in the following user’s manuals. Be sure to read them
before designing.
