MOS INTEGRATED CIRCUIT
μ
PD784054(A)
16-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The
μ
PD784054(A) is a product of the 78K/IV series, and based on the
μ
PD784044(A) with the real-time output
function and two units of timers/counters deleted and a standby function invalid mode provided. A stricter quality
assurance program applies to the
μ
PD784054(A) compared to the
μ
PD784054 (standard model).
The
μ
PD784054(A) is provided with many peripheral hardware functions such as ROM, RAM, I/O port, 10-bit
resolution A/D converter, timer, serial interface, and interrupt functions, in addition to a high-speed, high-performance
CPU.
Moreover, a flash memory model,
μ

Note
, that can operate on the same supply voltage as the mask ROM
model, and many development tools are under development.
Note
Use for functional evaluation only.
The functions are described in detail in the following User’s Manuals. Be sure to read these manuals when
designing your system.
