Overview
AT91 ARM-Based microcontroller
• The Atmel AT91 Series of microcontrollers are based upon
the powerful ARM7TDMI processor.
Atmel has taken these cores, added a wide range of
peripherals and advanced power management systems, to
give the design engineer the best of both worlds – a high
performance peripheral set with very low power
consumption.
It gives the buyer a 32-bit processor at 16-bit cost!

AT91x40 series: SRAM Integration
• From 8 to 256 Kbytes of SRAM
– 32-bit SRAM, 0 wait state, single cycle accessible
– Reach the maximum performance of the ARM Instruction Set
• Download the code from an external flash and run it
internally (code shadowing)
• Running out of internal SRAM reduces Power consumption
• Typical Applications
– High performance algorithms (DSP)
– Audio Decoding (MP3, WMA, …)
• MP3, WMA have been ported on AT91 products
– Software peripherals
• Software DMA channels
• High speed Software I2C
13
AT91 Flash-based
• AT91FR4042 and AT91FR40162
– R40008 plus 512Kbytes or 2 Mbytes Flash
• BGA 120 package (11x17mm²) ball pith 1mm
• AT91R40008
• AT49BV4096A or AT49BV16x4A (bottom-boot sector)

AT91M55800A: Designed for ultra
Low Power Applications
• Analog Functions
– 2 x 4-ch 10-bit ADC, target 20us sampling time
– 2-ch 10-bit DAC, target 3us settling time
• Digital Peripherals
– 2 x 3 Timer Counter channels
– 3 x USARTs, 1 x SPI driving up to 15 serial peripherals
• Advanced Power Management Controller
– On-Chip Oscillator 32KHz + RTC on Battery Power
– On-Chip Main Oscillator + PLL
– On-Chip System Shut-Down Control
• Memory Interface
– Up to 4 external banks of 16Mbytes
– 8kbytes on-chip SRAM
 TQFP176 or BGA176
15
AT91M42800A: Ideal for Permanent
Power Supply Systems
• Only one 32kHz Oscillator and 2 PLLs
– Run down to 512Hz to meet the lowest power consumption
– Keep a fast response to an event thanks to the Idle Mode
– Reach the maximum of performance with the PLL
• No accuracy due to the 32kHz crystal poor stability
(particularly in T°)
• 2 SPIs, 2 USARTs, 2 x 3 Timer Counter channels
• 1 System Timer
– Periodic Interval, Watchdog, Real Time
• TQFP 144 or BGA 144
