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,
|
Ø They
directly support up to 500 chips in various packages from over 20 manufacturers;
Ø There
is no need to buy various costly adapters or several types of
emluators;
Ø There
is no need to worry about occupying any resource. and enjoy it in your way;
(including clear and set ALE）;
ØThey
support the IAP function
;
Ø 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;
Ø They
support the IAP function;
Ø 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
■User's chip directly acts as target chip
■Don't need design so many
adapters. Different devices in same pin arrangement and same package share one adapter;
■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;
■Supported
up to 500 chips in various packages from over 20 manufacturers;
■Doesn't occupy any resources ;
■Support 12T/6T/4T devices;
■Speed
up to 40MHz when accessing to external memory
without pull-up resistor；
■Support the IAP function
■Support Surface Mount Devices with an
interface for in-circuit emulation
■Set and clear ALE randomly in application
■Debug in Keil uVsion2 as well as JY2X00 debugger environment ;
