Development Tools for 8051 microcontrollers

PICE-51 In-Circuit Emulator


This emulator model is intended to supports a few obsolete micro: NXP / Philips P89C66x, 87C552/554 and Dallas Semi DS80C320/520/530 microcontrollers only. All other 8051 MCU are supported by the Phyton PICE-52 in-circuit or JEM-52 OCD/JTAG

The image above displays an assembled PICE-51 emulator. This is a palm-size header comprised of three stackable boards: a Main Board, POD, and Adapter (from top to bottom). The Trace Cable allows to trace external signals and output triggers.

    • Real-time, non intrusive emulation up to 33 MHz (12-clock mode) and up to 20 MHz (6-clock mode)
    • 3V to 5V 8051 derivatives are supported
    • Up to 256K bytes program memory & 256K data memory (64K & 64K by default)
    • Memory mapping between the ICE and target with 256 bytes resolution
    • Up to 512K true hardware breakpoints
    • 4 complex breakpoints / triggers
    • Up to 16K frame deep by 64 bit wide trace buffer
    • 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
    • Trace cable with 8 probe inputs and 1 trigger output
    • Software controllable embedded clock generator
    • Connects to a PC serial port via a light cable opto-isolated for extra protection
    • Integrated development environment Project-51 that includes an editor, a project manager, the MCA-51 assembler
    • Source level and project level support for Keil, IAR, Raisonance, Altium, Hi-Tech, Intel, Avocet, GNU and other compilers
    • PDS-52 software simulator in included to the IDE
    • Donwnload a full versions of the Project-51 IDE and MCA-51 macro assembler.
