ATmegaS128

Radiation-Tolerant 8-bit AVR Microcontroller ATmegaS128 DATASHEET PRELIMINARY SUMMARY Introduction The Atmel® ATmegaS128 is a low-power CMOS 8-bit microcontroller based on the AVR® enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmegaS128 achieves throughputs close to 1MIPS per MHz. This empowers system designer to optimize the device for power consumption versus processing speed. Features High-performance, Low-power Atmel AVR 8-bit Microcontroller Advanced RISC Architecture – 133 Powerful Instructions - Most Single-clock Cycle Execution – 32 × 8 General Purpose Working Registers + Peripheral Control Registers – Fully Static Operation – Up to 8MIPS Throughput at 8MHz – On-chip 2-cycle Multiplier High Endurance Non-volatile Memory segments – 128KBytes of In-System Self-programmable Flash program memory – 4KBytes EEPROM – 4KBytes Internal SRAM – Write/Erase cycles: To Be Defined after characterization – Data retention: To Be Defined after characterization – Optional Boot Code Section with Independent Lock Bits In-System Programming by On-chip Boot Program True Read-While-Write Operation – Up to 64 KBytes Optional External Memory Space (ATmega103 compatibility mode) – Programming Lock for Software Security – SPI Interface for In-System Programming JTAG (IEEE std. 1149.1 Compliant) Interface – Boundary-scan Capabilities According to the JTAG Standard Atmel-41036BS-Radiation-Tolerant 8-bit AVR Microcontroller_Datasheet_Preli...
