AT91 S ERIES

ARM T HUMB - BASED M ICROCONTROLLERS AT91 microcontrollers,

the BEST combination of

low-power consumption,

32-bit performance and

16-bit system cost

l System-level integration on a standard product:

-ARM7TDMI? RISC processor core

-Optimal combination of large SRAM, ROM and Flash memories

-Wide choice of on-chip peripherals

-Low risk, low cost, rapid time-to-market

l High performance for compute-intensive applications:

-On-chip 32-bit architecture

-3-stage instruction execution

pipeline for high instruction

throughput

-Single-cycle memory access

through EBI

-Hardware multiplier plus barrel

shifter gives DSP capability

-PDC channels (on-chip DMA) free the processor for the application l
