μ
PD784031(A)
The
μ
PD784031(A) is a product of the
μ
PD784038 sub-series in the 78K/IV series. A stricter quality assurance
program applies to the
μ
PD784031(A) than the
μ
PD784031 (standard product). In terms of the NEC quality, the
μ
PD784031(A) is classified as the special grade.
The
μ
PD784031(A) contains various peripheral hardware such as RAM, I/O ports, 8-bit resolution A/D and D/A
converters, timers, serial interface, and interrupt functions, as well as a high-speed, high-performance CPU.
The
μ
PD784031(A) is a ROM-less product of the
μ
PD784035(A) and
μ
PD784036(A).
For specific functions and other detailed information, consult the following user’s manual.
