TX19A/H1 Series

Low-power 32-bit RISC microcontrollers featuring high-speed operation at 100 MHz and enhanced floating-point arithmetic
The TX19A/H1 Series of 32-bit RISC microcontrollers realizes approximately twice the processing speed of the TX19A Series, and offers enhanced floating-point arithmetic capability. These high-speed and low-power microcontrollers are ideal for digital consumer applications where increasingly high-performance and high-functionality products are being developed.
