NEC V850ES/JH3-E and V850ES/JJ3-E 32-bit All Flash Microcontrollers

NEC Electronics has developed nine new 32-bit All Flash microcontrollers (MCUs) with built-in Ethernet interface and embedded flash memory. The new products are ideal for remote and supervisory control of industrial devices and building-management systems and include six V850ES/JH3-E 128-pin variants and three V850ES/JJ3-E 144-pin variants. The sample prices of these new products vary depending on memory capacity, package type, and number of pins. For example, the 144-pin V850ES/JJ3-E MCU with 512 KB of Flash memory and 124 KB of RAM is priced at U.S. $12 per unit. Mass production is scheduled to begin in December 2009.

V850ES/JH3-E and V850ES/JJ3-E Microcontrollers Features

  • On-chip Ethernet media access controller (MAC)
    Each of the new MCUs integrates one-channel IEEE 802.3-compliant 10/100Base-T Ethernet MAC (note). This eliminates the need for an external Ethernet controller, making it possible to build a connected system at low-cost.

  • 512 KB of Embedded Flash Memory and 124 KB of RAM
    With up to 512 KB of flash memory and up to 124 KB of RAM, the V850ES/Jx3 family of MCUs can execute 103 Dhrystone million instructions per second (MIPS) at a clock speeds of 50 MHz. This makes it possible to run network software and system control program using its internal memory only, thereby facilitates the overall development process.

  • Variety of Peripheral Functions
    The new products include full-speed USB 2.0 interface, CAN interface, a motor control timer, and a real-time counter. These features allow designers to implement industry-standard communication technologies and to reduce external components and trim system development costs.

  • Network Software
    NEC Electronics provides a wide array of network software, including an optimized Ethernet driver, and a lightweight transmission control protocol/Internet protocol (TCP/IP) stack.
