83225

HV/Auto

mSesame is the highest-featured member of indie’s HV/Automotive series of ARM M0-based microcontrollers. Clocking at up to 20MHz, the ARM M0 core integrates 160kB of flash RAM and 8kB of SRAM on die for feature-rich applications or those requiring redundancy of data storage. It integrates a superheterodyne ISM-band ASK receiver operating at 433MHz and with sensitivity performance of -110 dBm. It also contains an ultrasonic shock sensor and is intended to support a wide array of applications including radio controlled industrial door and security systems as well as automotive alarm systems.

The iND83225 integrates multiple clocking options including a high accuracy (1%) 10MHz RC oscillator, low cost 3.58MHz XTAL oscillator, and low power (<1uA) 10kHz auxiliary clock. It also contains (3) 32 Bit timers, and a watchdog timer for high performance, low power designs.

mSesame has a very rich set of I/O capabilities. There are 15 high voltage (9-45V) GPIOs which can source 5mA or sink 25mA of current, 8 high voltage (9-45V) GPIOs which can sink 200mA in order to drive a relay coil plus 1 high voltage (9V-45V) GPIO which can source 200mA or sink 25mA and 12 low voltage (3.3V nominal) GPIOs.
