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.
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.
