SAN JOSE--Atmel Corp. claimed to be the first chip maker to offer a flash-based microcontroller using the ARM Thumb RISC architecture. The small AT91F40416 chip is being targeted at cost-sensitive sensor applications, such as global positioning satellite (GPS) systems in cars.
The device integrates 16-megabits of flash memory, the Thumb processor core licensed ARM Ltd. and peripherals. Atmel said typical current limitations of several milliamps can be achieved by reducing the maximum operating frequency to "a few 100 KHz." The company said only its AT91 MCU can provide required performance for applications at this low operating speed.
Housed in a 120-ball BGA package, the AT91F40416 costs $14 each in quantities of 10,000 units.
