    PICE-52 In-Circuit Emulator


    Main Features


    • Real-time non-intrusive emulation for selected 8051 microcontrollers;
    • Tiny emulator header that plugs directly into a target socket – 95x70x40 mm;
    • Connects to a PC USB or serial port;
    • Up to 2M bytes program memory & 512K data memory (64K + 64K by default);
    • Memory banking – up to 32 banks by 64K;Memory mapping between the ICE and target with 256 bytes resolution;
    • Up to 1M true hardware breakpoints at Program memory and memory access breakpoints;
    • Up to 1M true hardware breakpoints at Xdata memory access for Read & Write;
    • Breakpoints on access to on-chip data memories: SFRs, direct data memory, on-chip Xdata, etc.;
    • 4 complex breakpoints / triggers;
    • Up to 64K frame deep by 128 bit wide trace buffer (16K x 128K by default);
    • Trace cable with 8 micro hooks for entering signals and two hooks for outputting triggers;
    • Precisely programmable clock generator;
    • 48-bit on-board timer;
    • Shadow RAM provides target device RAM real-time access without disturbing emulation;
    • “On-the-fly” access to the memory, breakpoints, tracer, and timer;
    • Memory coverage feature enables finding “dead” code;
    • Precisely controlled voltage regulator 2.0 to 5.5V range;
    CodeMaster-52 IDE enables:


    • Project-level support for the Phyton assembler and C compilers from Keil, IAR and Raisonance;
    • Source-level debugging for all popular C compilers and assemblers;

    There are three main board configurations:

    • MR2-52-03U – provides emulation for 64K code + 64K data memory, does not support external memory banking;
    • MR2-52-05U – provides emulation for 1M code + 448K data memory, supports external memory banking.
    • MR2-52-06U – provides emulation for 2M code + 448K data memory, supports external memory banking.

    POD or a daughter module is built around an execution processor that emulates a behavior of the target MCU being under control of the loaded application program. PICE-52 can be equipped with a variety of changeable PR2-52-xxx pods.

    An Adapter provides mechanical connection of the emulator pod to the target board. It plugs directly to a DIP-40, PLCC-44 or QFP-44 target socket.


    Check if Phyton has an emulator for your 8051 device and request a quote

    Phyton has been producing and selling 8051 in-circuit emulators for more than 20 years and keep selling them nowadays. To check if our 8051 emulators support your target device and would like to get a quote, please email your inquiry to info@phyton.com. Your request should include the following information about the target device and your development environment:

    • Silicon manufacturer (for example: Atmel, NXP, Microchip, etc.);
    • Device part number (for example: AT89C52ED2, SST89E516RD2, etc.);
    • Mechanical chip package (for example: DIP 40-pin, PLCC 44-pin, etc.);
    • Whether your target board has an external memory and, if so, its memory structure;
    • A compiler brand, if used for project management.

    We will be sure to respond to your request promptly.
