Freescale Semiconductor is expanding its portfolio of 32-bit Kinetis microcontrollers (MCUs), based on the ARM Cortex-M4 processor, with 60 new entry-level devices that are expected to begin sampling in early 2012.
The new devices are additions to the Kinetis K10 and K20 families and are the lowest-power Kinetis MCUs to date, consuming only 630 μA at a CPU speed of 4 MHz in low-power run mode, which is equivalent to 160 μA/MHz; the lowest-power mode consumes only 40 nA.
The new K10 and K20 family members offer from 32 KB to 128 KB of Flash memory in 32-pin QFN (5 x 5 mm) to 64-pin LQFP packages. Devices are built using Freescale's 90 nm thin film storage (TFS) low-leakage Flash technology with up to 32 KB of optional FlexMemory (2 KB EEPROM), very low-power run and stop mode currents and fast wake-up times. Peripheral options include a 16-bit ADC, full-speed USB On-The-Go controller with complimentary software stack, low-power touch sensing interface and several general timing, communication and control peripherals.
The devices are targeted to a broad range of applications, including I/O modules for factory automation, portable healthcare instruments, USB microphones and gaming headsets, as well as smart grid applications that demand solid processing power with aggressive low-power profiles.
