The Tiny v2.1 autopilot uses a single Philips LPC2148 ARM7 based microcontroller.
The [http://www.arm.com/products/CPUs/families/ARM7Family.html ARM7] is a low-power 32-bit RISC processor core and the [http://www.standardics.philips.com/products/lpc2000/ Philips LPC2148] has 512KB on-chip Flash ROM, 40KB RAM and can be clocked at 60MHz.
 
Although critical control code such as the R/C interface and servo output are well segregated in Paparazzi software and well protected from interference from flaws in the stability/navigation/comm/payload code, great care must be taken when experimenting with new software as some errors can cause a the processor to halt or stall for extended periods causing total loss of control.
