MC68HC04J3 Datasheet 8-bit Microcontroller

Manufacturer: Motorola Semiconductor (now NXP Semiconductors)

Overview: MOTOROLA - SEMICONDUCTOR TECHNICAL DATA MC68HC04J~ II Technical Summary 8-Bit Microputer Unit MC68HC04J3 HCMOS microputer unit (MCU) device is a member of the M6804 Family of single-chip microputers. This device is tremendously versatile and cost effective. These qualities are based on the MCU's simple design and ability to process 8-bitvariables, one bit at a time. This technical summary contains limited information on the MC68HC04J3. For detailed information, refer to the advanced information data sheet for the MC68HC04J2, MC68HC04J3, and MC68HC04P3 8-bit microputers (MC68HC04J2/D) or to the M6804 MeV Manual (DLE404/D).

General Description

VDD AND VSS Power is supplied to the microputer using these two pins.

VDD is power, and VSS is ground.

' IRQ This pin provides the capability for asynchronously ap- plying an external interrupt to the micropu
