Electronics › Electronics › Looking for A Specific IC #Embedded System
I want to make a hand held device of very small dimensions, which incorporates 4 leds and a motor. I used an 8051 to control these leds and motor and code accordingly, but as size is a constraint I can’t afford to make use of 8051. The IC which is really small and runs these leds and motor for the 'n' number of alarms set using a clock and also the IC should even display the clock on an lcd or an led display.
Please can someone guide me how to achieve these functionalities using a small IC (Any basic level IC which can be implemented as an smd chip in later stages). Thank you in advance.
For Hand held devices You can go with ARM STM32 controller, Its the same they are using in fitbits. For complete teardown look the below link

Thank you for your advice, I will try it later.
Hello Joey,
You can use Lilypad Arduino Mainboard. It has 14 Digital I/O. Being size constraint, you can use 4 seven segment display to show time for which 8 GPIOs will be used in multiplexing. Now left with 6 GPIOs, 4 can be used to interface LEDs and two can be interfaced to switches for setting alarms. Of the two switches, one can be used to increament hours or minutes in loops and use other switch to transit to minutes from hours and then confirm alarm. On pressing the second switch only, the set alarms can be navigated otherwise the current time will be displayed on 7-segments by default. The board has 6 PWM pins of which 1 can be used to control motor.
