UPD78F4046 - 16-BIT SINGLE-CHIP MICROCONTROLLER

General Description

The µPD78F4046 is a product of the µPD784046 Subseries in the 78K/IV Series.

The µPD78F4046 has flash memory in place of the internal ROM of the µPD784046.

The incorporation of flash memory allows a program to be written or erased while mounted on the target board.

Key Features

  • 78K/IV Series Pin compatible with µPD784044, 784046 (except V PP pin) Flash memory: 64 KB Internal RAM: 2048 bytes Operable with the same supply voltage as that of the mask ROM version: VDD = 4.5 to 5.5 V.
