    Temat: elektronik do projektowania na 8051
    Od: "grzegorz" <n...@z...pl>

    Firma z okolicy Warszawy poszukuje do stałej pracy elektronika ze

    znajomością projektowania układów opartych na

    mikrokontrolerze serii uPSD34xx lub zbliżonych.

    (poniżej opis techniczny mikrokontrolera)

    The Turbo Plus uPSD34xx Series combines a powerful 8051-based

    microcontroller with a

    flexible memory structure, programmable logic, and a rich peripheral mix to

    form an ideal

    embedded controller. At its core is a fast 4-cycle 8032 MCU with a 4-byte

    instruction

    prefetch queue (PFQ) and a 4-entry fully associative branching cache (BC).

    The MCU is

    connected to a 16-bit internal instruction path to maximize performance,

    enabling loops of

    code in smaller localities to execute extremely fast. The 16-bit wide

    instruction path in the

    Turbo Plus Series allows double-byte instructions to be fetched from memory

    in a single

    memory cycle. This keeps the average performance near its peak performance

    (peak

    performance for 5V, 40MHz Turbo Plus uPSD34xx is 10 MIPS for single-byte

    instructions,

    and average performance will be approximately 9 MIPS for mix of single- and

    multi-byte

    instructions).

    USB 2.0 (full speed, 12Mbps) is included, providing 10 endpoints, each with

    its own 64-byte

    FIFO to maintain high data throughput. Endpoint 0 (Control Endpoint) uses

    two of the 10

    endpoints for In and Out directions, the remaining eight endpoints may be

    allocated in any

    mix to either type of transfers: Bulk or Interrupt.

    Code development is easily managed without a hardware In-Circuit Emulator by

    using the

    serial JTAG debug interface. JTAG is also used for In-System Programming

    (ISP) in as little

    as 10 seconds, perfect for manufacturing and lab development. The 8032 core

    is coupled to

    Programmable System Device (PSD) architecture to optimize the 8032 memory

    structure,

    offering two independent banks of Flash memory that can be placed at

    virtually any address

    within 8032 program or data address space, and easily paged beyond 64K bytes

    using onchip

    programmable decode logic.

    Dual Flash memory banks provide a robust solution for remote product updates

    in the field

    through In-Application Programming (IAP). Dual Flash banks also support

    EEPROM

    emulation, eliminating the need for external EEPROM chips.

    General purpose programmable logic (PLD) is included to build an endless

    variety of gluelogic,

    saving external logic devices. The PLD is configured using the software

    development

    tool, PSDsoft Express, available from the web at www.st.com/psm, at no

    charge.

    The uPSD34xx also includes supervisor functions such as a programmable

    watchdog timer

    and low-voltage reset.
