TI's tiny microcontroller is the world's smallest and costs less than 20 cents
Briefly

Texas Instruments has launched the MSPM0C1104, marketed as the world's smallest microcontroller, at only 1.38 mm² in size. This wafer chip-scale MCU is 38% smaller than its competitors, making it perfect for compact devices like medical wearables and personal electronics. Despite its size, it boasts a powerful 24 MHz Arm Cortex-M0+ processor, 16 KB flash, and low power consumption rates. Pricing starts at $0.16 per unit for bulk orders, supported by comprehensive development resources from TI to facilitate rapid prototype creation.
Texas Instruments has officially unveiled the MSPM0C1104, which it claims to be the world's smallest microcontroller. This remarkable device measures a mere 1.38 mm², which is only slightly larger than a flake of black pepper.
The MSPM0C1104 is a wafer chip-scale package microcontroller (MCU) that is 38% smaller than existing alternatives, making it an ideal solution for applications where board space is at a premium like medical wearables.
