MOS INTEGRATED CIRCUIT
µPD78052(A), 78053(A), 78054(A)
8-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
A stricter quality assurance program (called special grade in NEC’s grade classification) is applied to the
µPD78052(A), 78053(A), and 78054(A), compared to the µPD78052, 78053, and 78054, which are classified as
standard grade.
The µPD78052(A), 78053(A), and 78054(A) belong to the µPD78054 Subseries products of the 78K/0 Series.
These microcontrollers include the rich 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.
Various development tools are also available.
Details of the function description, etc., are described in the following User’s Manuals. Be sure to read
the documents when designing.
