INTRODUCTION:
BOARD FEATURES:
crocontrollers based on the 32-bit ARM RISC processor. It features a 256 Kbyte
high-speed Flash and a 64 Kbyte SRAM, a large set of peripherals, including a USB
2.0 device, and a complete set of system functions minimizing the number of ex-
ternal components. The device is an ideal migration path for 8-bit microcontroller
users looking for additional performance and extended memory.
ICE interface 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.
of managing the power-on sequence of the microcontroller and the complete sys-
tem. Correct device operation can be monitored by a built-in brownout detector
and a watchdog running off an integrated RC oscillator.
USB Device port makes it an ideal device for peripheral applications requiring con-
nectivity to a PC or cellular phone. Its aggressive price point and high level of in-
tegration pushes its scope of use far into the cost-sensitive, high-volume consumer
market.
