DESCRIPTION

The μPD784054(A) is a product of the 78K/IV series, and based on the μPD784044(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 μPD784054(A) compared to the μPD784054 (standard model).

The μPD784054(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, μPD78F4046Note, that can operate on the same supply voltage as the mask ROM model, and many development tools are under development.
