Introduction

ICE52F emulator is an enhanced USB2.0 interface 51 single-chip microcomputer emulator newly developed by Shenzhen Sofi Technology Co., Ltd. based on the well-received ICE52B emulator. The emulation does not occupy any resources of the user, and can be stepped at a high speed. It is a completely true emulation standard. All the functions of the 8051/8052 microcontroller can emulate the enhanced functions of some microcontrollers. In addition to powerful simulation functions, the unique ISP download function can support ISP download programming for 51 series and AVR series microcontrollers. Many innovative functions and technologies of ICE52F emulator are in the leading position among the products below thousand yuan in the same industry, with extraordinary cost performance. It is the most ideal tool for engineers to develop single-chip products, college teaching, and personal learning of single-chip.

Features

Innovative functions

● Using the Keil simulation driver protocol independently developed by Sofi Technology, it can perfectly integrate with the Keil development environment and realize the real USB2.0 interface communication without any setting operation. Other emulators below a thousand yuan and simple emulators using the SST public version program use the MON51 driver protocol and can only use serial ports. Some products use USB-to-serial chips (although they are also USB port communication, but the essence is still a serial port) Slow speed, need to manually set the port number and baud rate;

● Support software reset, no need to reset hardware manually. There are no jumpers, switches or buttons inside the emulator, and continuous code download and emulation operations can be performed through the emulation driver;
● It adopts a miniature embedded simulation adapter, which is close to the user board when inserting, and can freely choose the internal default crystal or external target board 1-40M crystal (there are no limitations that can only use several fixed built-in crystals). In addition, compared with the traditional cable connection method, because there is no lead-out address line and data line, it can effectively reduce the interference during operation and avoid inexplicable failures during emulation;
● Exclusive integrated ISP download function, the first to support Keil's Flash Download function (can be directly implemented in the keil 51 series chip ISP download programming). If cooperated with professionally developed professional programming control software SFISP, it can support ISP download programming of AT89S / AVR series single-chip microcomputer chip. This function will bring you great convenience in product development and learning process;
● Free installation driver, plug to usage, support winxp, win7 (32-bit / 64-bit);
● The main control chip adopts a 32-bit ARM chip and supports automatic firmware upgrade;
● Support 3.3V / 5V dual voltage;
● The host has a buffer isolation chip, which effectively protects the main control chip from being damaged by abnormal operations;
● High sensitive overload and short circuit intelligent protection function controlled by CPU. If there is an accidental short circuit, it can immediately cut off the power and flash the LED alarm to effectively protect the emulator hardware and the computer USB port.

Special feature
● USB2.0 interface (real USB interface, not USB to serial port);

● Fast code download, single-step operation such as flying, no difference in emulation speed with professional emulators such as HOOKS and above;
● Can emulate ATMEL, WINBOND, DALLAS, INTEL, SST, PHILIPS and other compatible 51 and 52 microcontrollers;
● It does not occupy resources, especially does not occupy important resources such as IO ports, serial ports, and timers, and can completely emulate the characteristics of all ports of the microcontroller;
● Supports offline operation. At this time, the emulation head is equivalent to a chip programmed on the target board, which can be run more realistically, and the next time you power on, you can still run the program you downloaded last time;
● Support standard emulation operations, such as full speed, single step, stepped operation, setting / disabling / cancelling of breakpoints, register and variable viewing;
● Support the function of pause (dead) during operation;
● Can emulate dual DPTR, PCA, ALE disable, SPI interface, on-chip 768-byte extended RAM and other enhanced 51 microcontroller resources;
● Up to 63K code simulation space, support external 64K extended RAM emulation;
● Using Flash loop technology, users do not need to worry about the problem of Flash burnout;
● Exquisite and compact plastic case (size 102x71x23mm), it is very convenient to use and carry.

Small and exquisite emulator

Humanized design of the emulation head, the pins can be easily replaced, no worries to be broken

Introduction of ISP Download Function

In addition to the professional emulation function, ICE52F also has an exclusive integrated ISP download function, which can directly support downloading programs to the single-chip microcomputer in the keil software and Sofi download software "SFISP".

ISP download hardware connection diagram:

ISP download of AT89S series microcontrollers in Keil (ICE52F has a download function integrated in Keil software, which can complete all processes from source program editing, compilation, emulation, chip programming, etc., without the need to develop software and programming Frequent switching between writing software, this function is suitable for debugging programs in the product development stage)

With the downloading software "SFISP" developed by Sofi, it can also support ISP download of AT89S5x series and AVR series microcontrollers.
