  • Description

    The uPD74HCT04G-E2 is an electronic component model of IC chips. It is an LSI floppy disk controller (FDC) chip which contains the circuitry and control functions for interfacing a processor to 4 floppy disk drives. The uPD74HCT04G-E2 is capable of either IBM 3740 single density format (FM), or IBM System 34 double density format (MFM) including double-sided recording. It provides control signals which simplify the design of an external phase-locked loop and write precompensation circuitry. The uPD74HCT04G-E2 simplifies and handles most of the burdens associated with implementing a floppy disk interface.

    Specifications and features

    Address mark detection circuitry is internal to the FDC which simplifies the phase-locked loop and read electronics. The track stepping rate, head load time, and head unload time are user-programmable. The uPD74HCT04G-E2 offers additional features such as multi-track and multi-side read and write commands, and single and double density capabilities.

    • FM, MFM Control
    • Variable recording length: 128,256, .8192 bytes/ sector
    • IBM-compatible format (single- and double-sided, single- and double-density)
    • Multi-sector and multi-track transfer capability
    • Drive up to 4 floppy or micro floppy disk drives
    • Data scan capability-will scan a single sector or an entire cylinder comparing byte-for-byte host memory and disk data
    • Data transfers in DMA or non-DMA mode
    • Parallel seek operations on up to four drives
    • Compatible with uPD8080/85, uPD8086/88, V-series and uPD780 ( [email protected] ) microprocessors
    • Single-phase clock: 8 MHz maximum 3 +5V only

    Application Scenarios

    The uPD74HCT04G-E2 is commonly used in devices that require floppy disk control, such as computers, industrial equipment, and retro gaming consoles.
