Atmel's new in-circuit-emulator, the ICE 50, supports new members of the company's megaAVR and tinyAVR family of 8-bit microcontrollers. Atmel says that as a part of its strategy to help design engineers reduce development costs, design time and ultimately, production costs, the ICE 50 emulates all analog and digital peripherals and debugs all instructions and features in realtime. It additionally has new profiling capabilities that track subroutine usage, which allows the user to optimise code that is frequently accessed.
ICE 50 can be used to control the execution of the AVR microcontroller over the full voltage and frequency range of supported AVR devices. It supports the new Self-Programming-Memory capability and provides the user with accurate electrical and timing characteristics, says Atmel. All available package types including its new and popular micro-lead frame package, are supported through emulation adapters available from third party suppliers.
"Atmel's ICE 50 enables users to set an unlimited number of breakpoints. In addition to traditional instruction break points, which stop execution when a specific point in the program is met, ICE 50 has data breakpoints that stop emulation when a certain parameter is in the system," said Jim Panfil, director of microcontroller products. "For example, a break point can trigger when data is received from an external system or when a parameter reaches a specific value."
AVR Studio is the common user interface for ICE 50 and other AVR development tools. It resides on a PC and can control all user settings. This eliminates the need to manually set jumpers on the emulator. Users have full visibility and access to RAM, EEPROM, Flash program memory and register files. ICE 50 is designed to be an expandable debug platform, and can be modified to support new AVR devices as they are released. A logic analyser interface and high-speed communication interface capability will be available as plug-in modules soon, says the manufacturer.
