Atmel Introduces New JTAG In-Circuit-Emulator Targeted to Increase Speed and Accuracy While Reducing Development Costs
SAN JOSE, Calif.--(BUSINESS WIRE)--Oct. 1, 2001--Atmel Corporation
(Nasdaq: ATML) announced today the availability of a new low cost
in-circuit-emulator (ICE) that supports all megaAVR® 8-bit
Microcontrollers with a JTAG interface. As a part of Atmel's strategy
to help the design engineer drastically reduce development costs,
design time and ultimately production costs, the JTAG ICE represents a
revolutionary new approach to debug 8-bit microcontollers, previously
only cost justified on 32-bit cpu's. Atmel's advanced process
technology used on the megaAVR family allows cost effective
integration of debug logic on 8-bit microcontrollers with memory sizes
as small as 16KB.
The JTAG ICE can be used to control the execution of the megaAVR
and provides the user with exact electrical and timing
characteristics. This capability is not available on traditional ICEs.
The JTAG interface allows high-speed communication with the target
device thus eliminating the bottleneck associated with other on-chip
debug methods. The JTAG ICE communicates with the on-chip debug block
via the test access port and can execute code and monitor results in
the megaAVR microcontroller. The emulation interface is independent of
clock frequency, which will result in significantly communication and
debugging when the device is clocked at any frequency between 32-KHz
to 16-MHz.
The megaAVR JTAG interface is an IEEE 1149.1 compliant four wire
test access port that provides a standard way to implement boundary
scan and on-chip debug. Atmel has extended this capability to include
full system programming and on-chip debug support. Cost is reduced by
off loading expensive SRAM and emulation circuits from ICE to using
existing resources on chip.
``Atmel's JTAG ICE enable users to do real time emulation on the
microcontroller while it is running in the target system,'' said Jim
Panfil, Director of Microcontroller Products. ``The on-chip debug
protocol gives the user complete control of the internal resources of
the megaAVR and the ability to set hardware and software breakpoints
at a fraction of the cost of traditional emulators.'' He added.
AVR Studio® is the common user interface for JTAG ICE and all
other AVR® development tools. Debug Features include the ability to
set four hardware and an unlimited number of software break points.
Two of the hardware breakpoints can be placed in the data memory
providing the capability to break when a specific RAM address is
accessed.
The JTAG ICE system is available from authorized Atmel
distributors at a suggested resale price of $299. The ordering code is
ATJTAG ICE. Availability is 2-4 weeks.
