Technical advantages
|
-
What the engineers have resorted to are the emluators that occupy most CPU resources before importing the
Hooks technology.
-
Although the problem of occupying CPU resources has been solved by Hooks,the emluator is of high price and
low simulating frequency.
-
The problems of not supporting 8051 standard resources and low frequency are solved by Bondout chips (such as
W77968,W78958), but the number of the supported chips is small , and the enhanced resources can not be
supported.
-
When W78958 chips are discontinued, we return to the period of Hooks. Although the cost performance has been
improved a lot, the emluator in Hooks only support chips from few manufacturers.
-
With more and more CPU manufacturers in the market and CPU resources developing, there exist various kinds of
problems when emulating in compatibility modes, problems such as unfull coverage of resources (such as
appendent ports, external interrupts),differences in address distribution (such as P4),and operation (such as
EXTRAM¡¢WTD).
-
If the emluators want to support 500 chips in various packages from over 20 manufacturers with special chips,
the engineers should design a great of adapters.
|
Since the JY-E2X00 series emluators adopted new patent technology come into market,
 They directly support up to 500 chips in various packages from over 20 manufacturers;
There is no need to buy various costly adapters or several types of emluators;
There is no need to worry about occupying any resource. and enjoy it in your way;(including clear and set ALE);
They support the IAP function;
Because of the interface for in-circuit emulation, there is no need to worry about not the surface mount devices
,such as QFP44,QFP52,QFP64 and so on;
They support the IAP function;
There is no need to connect P0 to external pull-up resistors or cut down the frequency when accessing external
RAM, and speed up to 40MHz .P0 and P2 can be used as address/data bus as well as I/O port in one application.

Features
¡ö User's chip directly acts as target chip
¡ö Don't need design so many adapters.Different devices in same pin arrangement and same package share one adapter;
¡ö It gets rid of such weak points as having to change the definition and being unable to totally cover the
resources by Hooks and Bondout;
¡ö Supported up to 500 chips in various packages from over 20 manufacturers;
¡ö Doesn't occupy any resources ;
¡ö Support 12T/6T/4T devices;
¡ö Speed up to 40MHz when accessing to external memory without pull-up resistor;
¡ö Support the IAP function
¡ö Support Surface Mount Devices with an interface for in-circuit emulation
¡ö Set and clear ALE randomly in application
¡ö Debug in Keil uVsion2 as well as JY2X00 debugger environment;
