Rad-Tolerant megaAVR MCU for Space Applications

Atmel Corp. is now shipping the ATmegaS128 microcontroller targeting next-generation space applications. Atmel’s first Rad-Tolerant device, ATmegaS128 delivers full wafer lot traceability, a 64-lead  CQFP, space screening, space qualification according to QML and ESCC flow, and total ionizing dose up to 30 Krad (Si) for space applications.

The ATmegaS128 is available in a ceramic hermetic packaging and is pin-to-pin and drop-in compatible with existing ATmega128 MCUs. This provides flexibility between commercial and qualified devices and thus enables faster time-to-market and lower development costs.

Features and specs:

  • High-performance, low-power Atmel AVR 8-bit MCU
  • High endurance, non-volatile memory
  • Robust peripherals including 8- and 16-bit timers/counters, 6 PWM channels, 8-channel, 10-bit ADC, TWI/USARTs/SPI serial interface, programmable watchdog timer, on-chip analog compactor
  • Power-on reset and programmable brown-out detection
  • Internal calibrated RC oscillator
  • External and internal interrupt sources
  • Six sleep modes
  • Power-down, standby and extended standby

A complete STK600 starter kit and development system for the ATmegaS128 AVR MCU is available. You can design with an industrial version of the ATmega128—with the exact pin-out of the ATmegaS128—to save costs. The new AVRs are supported by the proven Atmel Studio IDP for developing and debugging Atmel SMART ARM processor-based MCUs and Atmel AVR MCU applications, along with the Atmel Software Framework.
