UPD753304 Datasheet (NEC) - 4-BIT SINGLE-CHIP MICROCONTROLLER

UPD753304, 4-BIT SINGLE-CHIP MICROCONTROLLER

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.

While the conventional 75X series products with an on-chip LCD contr

UPD753304 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.)

* Pr
