Renesas Electronics UPD78F1146AGB(R)-GAH-AX, 16bit 78K0R Microcontroller, 78K, 20MHz, 256 kB Flash, 64-Pin LFQFP

The 78K series of Microcontrollers by Renesas are suitable for a wide range of applications.
78K0R/Kx3 microcontrollers are 16-bit low-power 78K0R CPU core, timers, A/D converters and serial interfaces. The power consumption is the same as an 8-Bit microcontroller and is for Consumer, Communication and Industrial applications.

Key Features:
