UPD78F0034AY - 8 Bit Single Chip Microcontroller

Download the UPD78F0034AY datasheet PDF. This datasheet also covers the UPD78F0034A variant, as both devices belong to the same 8 bit single chip microcontroller family and are provided as variant models within a single manufacturer datasheet.

General Description

µPD780034A but with flash memory in place of internal ROM.

The µPD78F0034AY is a member of the µPD780034AY Subseries, featuring flash memory in place of the internal ROM of the µPD780034AY.

Key Features

  • Pin-compatible with mask ROM versions (except VPP pin).
  • Flash memory:.
  • Supply voltage: Note 32 KBNote VDD = 1.8 to 5.5 V.
  • Internal high-speed RAM: 1,024 bytesNote The flash memory and internal high-speed RAM capacities can be changed with the memory size switching register (IMS). Remark For the differences between the flash memory and the mask ROM versions, refer to 4.
