USB2.0 Interface
● USB2.0 interface combines USB1.1
● Its power supply needs no extra power adapters, and thus is simple and convenient
● Its special USB2.0 chips are not simulated USB or USB to serial ports, and thus ensure the stability and speed of programming
● Its in-built ESD protects circuit, prevents programmers and computer interfaces from induction voltage and static electricity of computer shells, and thus improves the stability and security of programming
Built-in 32-bit high-speed processors
 |
● The hardware of the built-in 32-bit high-speed processors is optimized specially for SPI Flash and Serial EEPROM, and thus ensures stable and high-speed reading and writing.
● The programming process of all chips is completed by the built-in processors, without influence from computer master frequency.
● High-speed processors are a guarantee for speedy and efficient programming, and special hardware design is also a premise for speed and stability |
High-speed programming
● SP8 is currently the programmers with the highest programming speed in the industry, even quicker than general programmers and similar special programmers which cost over 1000 RMB.
(Take 8M-bit EN25T80 as an example, SP8-A: read-1.24S, write-5.44S; Superpro 580U: read-4.15S, write-9.31S)
● Through built-in high-speed processors and special hardware design, SP8 realizes high-speed and reliable programming, especially for serial FLASH and EEPROM.
● Arithmetic optimizations for different chips

Intelligent pin detection
● The whole SP8 series has the function of intelligent pin detection.
● Pin detection can effectively avoid failure or low success of programming caused by oxidation or misplacement of chips or problems from the adapters, and thus improves the efficiency of programming.
● It presents via pictures the contact information of pins, like bad contact, fine contact, not used, and ignored
Protection against over-current and short circuit
 |
● With perfect system of over-current detection and short circuit protection
● Effectively protects programmers from damages of misplaced chips (wrong position or direction), or wrong types of chips, or short circuit of chips or adapters
● You do not have to worry that the chips might be burnt due to damages of misplaced chips (wrong position or direction), or wrong types of chips
● ISP interfaces also have protection function against over-current and short circuit, and automatically detect the supply conflicts of target boards (or target chips) |
40PIN general ZIF socket
● Adopts 40PIN gilded ZIF socket for wide/narrow dual purposes.
● Can be directly applied to inline chips with eight to sixteen pins.
● Can directly use any general adapter, with a pin width of either 300mil or 600mil.
● Can directly use an adapter with up to 40 pins.
SP8 was originally designed with a 16-pin ZIF socket(the left figure below), which was found later to support only 300mil chips and adapters. However, adapters available in the market are basically 600mil, and thus cannot insert into a 16-pin ZIF socket, which limits the application of such SP8. Based on this reason, SOFI decisively modified its moulds and adopted 40-pin narrow applicable ZIF socket .
Support online programming(ISP)
● Some patch chips can be programmed directly via ISP, avoiding the problem of unsoldering.
● The whole SP8 series has special ISP interfaces buffered with special chips, and supports 2.0V~5.5V target boards (chips).
ISP interfaces can be set up via software whether to supply power to the target boards (voltage can be set at 3.3V or 5V).
● ISP power supply has protection function against over-current and short circuit, automatically detects the supply situation of target boards and thus avoids power supply conflicts.
● It can be used to online upgrade of main-board BIOS (application example: Use SP8-A programmer to upgrade online BIOS of MSI MS-7392 main-board;（website：用SP8-A编程器在线升级微星MS-7392主板BIOS ）
|
SP8 has an ISP interface and a download cable with 10-color single DuPont heads

Uses the ISP download function of SP8 to upgrade online main-board BIOS

Both SP8-B and SP8-F support online high-speed mass production, but only SP8-F has the function of offline mass production, which is very applicable to mass programming memories and thus saves much costs for equipment purchase and labor. Note: SP8-A does not have the function of mass production, and applies only to researchers and maintenance personnel.
