The iND81202 is a member of the general purpose microcontroller family of products from indie. It is a highly integrated 32-bit general purpose ARM M0 based microcontroller which clocks at up to 20MHz.
Gray features a high performance 32-bit wide ARM M0 core with 160kB of flash RAM and 8kB of SRAM. A real time clock (RTC), 12MHz RC oscillator, 32kHz sleep mode clock, 10kHz auxiliary clock, and watchdog timer are all fully integrated on die for high performance, low power design.
The iND81202 includes integrated power management and is capable of running entirely off either a 3V battery or the integrated USB port. An integrated charge pump is capable of generating 4.5V from the battery and supplies power to the LCD. No other components are required for power regulation of the IC, creating an efficient, low cost design.
Gray also integrates an LCD driver to provide a flexible visual display option for various applications needs. The driver can program up to 120 display elements in a 4 x 30 LCD segment display for feature-rich measurement readouts.
