This low power, high performance 16-bit microcontroller is backed by a truly high degree of fully implemented on-chip peripherals that present designers with real application enhancement opportunities today, as well as significant cost-savings and simpler design.
One such opportunity includes three fully specified, highly accurate oscillator circuits providing up to 20MHz performance on-chip at +/-1% accuracy, and enabling selection of 1MHz, 8MHz or 20MHz clocks whilst completely removing the need for an external clock circuit.
Innovative new analog circuitry has also been implemented on-chip, including accurate, high-speed A/D converters that work across the entire supply voltage range plus on-chip x1 to x12 programmable operational amplifier and 2 comparator channels making the 78K0R/Kx3-L an ideal selection for sensor applications.For power-critical applications, further enhancements to increase battery lifetime include Flash programming down to 1.8V and a 1.8V to 5.5V supply voltage, without restriction, across the entire family.
Fully flexible 16-bit timer and serial interface array units plus standard peripherals such as the Real-Time Clock, DMA controller, windowed Watchdog timer and other safety functions complete 78K0R/Kx3-L’s highly integrated peripheral set. Embedded Flash memory sizes start from just 16KB, with variants all the way up to 512KB available across the 78K0R family, providing a flexible and seamless upgrade path to more functionality if required. In common with all NEC Electronics microcontrollers, 78K0R/Kx3-L are specified across the entire temperature and supply voltage ranges.
78K0R/Kx3-L samples started shipping in August 2008, with mass production of the 22 new devices following later in the year.
