Miniature microcontroller fits space-constrained applications

When designers undertake applications with extreme space limitations, such as wireless sensing nodes, home automation systems, and portable health and fitness products, package size becomes a critical component selection factor. Extending its EFM32 Gecko range of microcontrollers to meet these requirements, Energy Micro added products supplied in thin, fine-pitch BGA48 packaging.

Based on the ARM Cortex-M3 processor, the new Tiny Gecko devices require a current of just 150 microamps/MHz when active. Despite their small size (4 mm x 4 mm x 1 mm), the VFBGA48 Tiny Gecko devices include several energy-friendly peripherals, including the company’s low-power LCD driver technology and the LESENSE low-energy sensor interface. The LESENSE function enables monitoring of a mix of up to 16 capacitive, inductive, or resistive sensors independently from the processor core. The Cortex-M3 Tiny Gecko microcontrollers run at clock speeds up to 32 MHz and are equipped with up to 32 KB of flash memory and 4 KB of RAM. The RoHS-compliant VFBGA48 devices will be available in sample quantities in Q3 2012.
