Description  
Atmel’s AT91SAM7S32 is a member of a series of low pin count Flash microcontrollers  
based on the 32-bit ARM RISC processor. It features a 32 Kbyte high-speed Flash and  
an 8 Kbyte SRAM, a large set of peripherals and a complete set of system functions  
minimizing the number of external components. The device is an ideal migration path for  
8-bit microcontroller users looking for additional performance and extended memory.  
The embedded Flash memory can be programmed in-system via the JTAG-ICE inter-  
face or via a parallel interface on a production programmer prior to mounting. Built-in  
lock bits and a security bit protect the firmware from accidental overwrite and preserves  
its confidentiality.  
The AT91SAM7S32 system controller includes a reset controller capable of managing  
the power-on sequence of the microcontroller and the complete system. Correct device  
operation can be monitored by a built-in brownout detector and a watchdog running off  
an integrated RC oscillator.  
The AT91SAM7S32 is a general-purpose microcontroller. Its aggressive price point and  
high level of integration pushes its scope of use far into the cost-sensitive, high-volume  
consumer market.
