NEC Electronics has launched twelve new 16-bit All Flash microcontrollers (MCUs) with built-in universal serial bus (USB) 2.0 functionality and low-power consumption. The new offering includes six 48-pin MCUs (78K0R/KC3-L) and six 64-pin MCUs (78K0R/KE3-L) with flash memory options ranging from 64KB to 128KB.
The company said that it has implemented USB functionality on its low-power 78K0R/Kx3-L family of MCUs to maximise product and battery life and minimise power consumption, to address the concerns of system designers about power consumption and battery life of the products that are battery-driven.
According to NEC, the features of new offerings include a range of USB offerings including USB drivers to handle device-specific functionality and other related tasks and the new MCUs combine NEC’s low-power 78K0R/Kx3-L 16-bit CPU with its USB 2.0 function controller. Achieving a low standby-power consumption of 1.2µW, the MCUs enable a low-active CPU-operation power consumption of 20mW at 20MHz.
In addition to USB functionality, the new products come with a mix of MCU peripherals including 10-bit A/D converters, 16-bit timers, real-time clock, watch-dog timer, 16-bit pulse-width modulator (PWM), I²C (inter-integrated circuit) and UARTs, the company said.
The new MCUs mass production is expected to begin in the second quarter of 2010. Suggested distribution resale pricing for 10,000-unit quantities ranges from $3.40 to $4.55, depending on memory size, package and peripherals.
