Energy Micro EFM32 Tiny Gecko Microcontrollers

Energy Micro introduced thirteen EFM32 Tiny Gecko (TG) microcontrollers. At a sub-Dollar price, the EFM32 Tiny Gecko (TG) microcontrollers offer the energy-efficient performance of the bigger Gecko products combined with smaller Flash and RAM combinations and a choice of space saving QFN20, QFN32, and QFN64 packaging. Prices start at $0.99 USD each in 100 K quantities.

Energy Micro EFM32 Tiny Gecko Microcontrollers

  • ARM Cortex-M3 architecture
  • Use less than a quarter of the energy needed by alternative 8-, 16- or 32-bit microcontrollers
  • Wake-up time of under 2µs
  • QFN20 packaged EFM32TG100 devices provide Flash and RAM capacities of respectively 4 to 32KB and 1 to 4KB and 12 GPIO
  • QFN32 packaged TG200 and QFN64 packaged TG230 and TG840 provide Flash options of 8, 16 and 32KB and either 2 or 4KB of RAM and 24 or 56 GPIO
  • Tiny Gecko products offer the same energy saving features and most of the peripherals of the larger Gecko products
  • TG840 devices embed a 4×24 segment LCD controller consuming less than 900nA
  • All TG parts offer an AES encryption / decryption engine as standard
  • Low energy UART and I2C serial interfaces
  • A/D and D/A converters
  • Counters and timers
  • Peripheral reflex system run in parallel with the standard 32-bit ARM bus
  • Peripherals run and communicate autonomously while the CPU is turned off
