UPD753304 - 4-BIT SINGLE-CHIP MICROCONTROLLER

General Description

The µPD753304 is one of the 75XL series 4-bit single-chip microcontroller chips and has a data processing capability comparable to that of an 8-bit microcontroller.

Since it inherits the 75X series CPU, it has upward compatibility.

Key Features

  • RC oscillation circuit on chip.
  • Main system clock: fCC = 3.6 MHz (typical value with 6.8-kΩ external resistor connected. An internal 10-pF (typ. ) capacitor is provided. ).
  • Subsystem clock : fCT = 47 kHz (typ. ) (Both a resistor and a capacitor are provided internally. ).
  • Processing can be started immediately after standby mode is released.
  • Oscillation of the subsystem clock can be stopped in STOP mode.
  • Supply voltage: VDD = 2.5 to 5.5 V.
  • On-.

304 is one of the 75XL series 4-bit single-chip microcontroller chips and has a data processing capability comparable to that of an 8-bit microcontroller. Since it inherits the 75X series CPU, it has upward compatibility. While the conventional 75X series products with an on-chip LCD controller/driver use an 80-pin package, the µPD753304 is sold as a pellet/wafer to make it possible to be built into portable devices with an LCD display function, etc. For detailed function descriptions, refer to the following user’s manual. µPD753304 User’s Manual: U12020E FEATURES • RC oscillation circuit on chip · Main system clock: fCC =
