NEC V850ES/Jx3-H and V850ESJx3-U 32-Bit Microcontrollers

NEC Electronics recently launched twelve new 32-bit devices with complete USB functionality on a single chip. The new 32-bit V850ES/Jx3-H and V850ESJx3-U MCUs execute USB 2.0 data transfers at high speeds up to 12 megabits per second (Mbps), and enable rapid development of applications that require USB connectivity and 32-bit processing power for real-time control of industrial equipment, factory automation systems, point-of-sales terminals, medical and testing devices, telecommunications and consumer electronics products and other embedded applications.

Samples are available now in several pin count, memory and USB function configurations. Pricing varies depending on features. For example, pricing for the high-end V850ES/JH3-U lineup, which features 512 kilobytes (KB) of flash memory, 56 KB of SRAM, and USB host and peripheral functions, is $9.50 per unit in sample quantities. (Pricing and availability are subject to change without notice.)

Based on NEC Electronics’ 32-bit V850ES core, the MCUs offer the following key advantages: fast execution of instructions per clock cycle at 1.9 Dhrystone million instructions per second (MIPS) per megahertz (MHz), efficient RISC CPU core with five-stage pipeline and CISC instructions, and low power consumption.

The four chips in the V850ES/Jx3-U lineup provide both USB host and function capability, while the eight chips in the V850ES/Jx3-H lineup provide USB function capability only. All of the new devices have the same instruction set and development environment as other V850-based cores, making it easy for designers to migrate from one V850 core to another.

Operation at a clock speed of 48 MHz enables the chips to execute 98 million instructions per second (MIPS). Like NEC Electronics’ general-purpose V850ES/JG3 and V850ES/JJ3 MCUs, the new products also feature on-chip peripheral functions such as a motor control timer and real-time counter that simplify system design and contribute to lower component counts and smaller board sizes.
