Atmel recently launched the radiation-resistant 32-bit SPARC V8 processor AT697. Compared with previous SPARC processors, AT697 has an 8-fold increase in speed/power consumption, providing enhanced computing capabilities for space equipment, while the package is 3 times smaller.

The AT697 CPU is compatible with LEON2-FT 1.0.13, has 8 register windows, and the advanced architecture has an on-chip Amba bus and 5-stage pipeline, 16KB multi-set data cache, and 32KB multi-set instruction cache. The on-chip peripherals include PROM controller, SRAM controller and SDRAM controller memory interface, two 24-bit timers and watchdog timer, and two 8-bit UARTs. There are 4 interrupt controllers with external programmable inputs, 32 parallel I/O interfaces, 33MHz PCI interface and 2.2 PCI standard compatible, integrated 32/64-bit IEEE 754 floating point unit, full triple module redundancy (TMR), EDAC protection and parity protection, debug support unit for tracking and debugging, IEEE 1149.1 JTAG interface, and four hardware observation points. The

core voltage is 1.8V+/-0.15V, and the I/O voltage is 3.3V+/-0.3V. The operating temperature is -55 degrees to 125 degrees C, the clock is from 0MHz to 100MHz, the power consumption is 1W at 100MHz, the performance reaches 86MIPS (Dhrystone 2.1) and 23MFLOPS (Whetstone), the total radiation dose is 100Krads (Si), the package is MCGA349, the weight is 9 grams, and it can be used in radiation-resistant equipment such as aerospace.

The AT697 processor is packaged in a 349-pin hermetic ceramic MCGA package.

Samples of the AT697 are available. The AT697E will be sent to QML-Q for testing at the end of 2005; the second version of the AT697 will also be sent to QML Q & V or ESCC for testing at the end of 2006.

Software upgrades are available for the AT697-EVA and its toolkit AT697-DKIT. The AT697-EVA includes the AT697 processor sample and BCC, RCC. The toolkit integrates GRMON error detection.
