MCUs gain more memory and on-chip peripherals

Edited by the Electronicstalk editorial team Sep 23, 2003

The latest additions to the S-Line range of RISC based microcontrollers from NEC are designed to cater for memory-hungry embedded and EMI-sensitive applications.

The latest additions to the S-Line range of RISC based microcontrollers from NEC are designed to cater for memory-hungry embedded and EMI-sensitive applications.

More than 25 new products in this family support CAN and I2C interfaces, supported by 100-pin (SG2) and 144-pin (SJ2) devices, fully packed with functionality.

Together with CAN-less devices the S-Line offers the necessary flexibility for numerous applications in the automotive sector and in industrial designs such as motor control or building management.

The single-chip V850ES/SJ2 is the second member of NEC's new S-Line family, which offers a wide variety of memory configurations with densities up to 640Kbyte ROM and 48Kbyte RAM.

V850ES/SJ2 supports a host of onboard peripherals and up to two CAN interfaces.

An equivalent single-voltage Flash device is available for most ROM devices.

Features of the V850ES/SJ2 include a 32bit RISC CPU operating at 20MHz giving a 50ns minimum instruction execution time.

On chip facilities include 124 I/Os, four standard UARTs, six three-wire serial interfaces (CSI), a 16-channel A/D convertor with 10bit resolution, two channels of D/A convertor with 8bit resolution, eleven 16bit timers plus a watch timer and watchdog timer.

It supports four channels of DMA and has two optional I2C and two CAN buses.

On chip debugging facilities help development with this device.

Sunrise Electronics can also provide design-in support and a range of development and debugging tools and software.

The V850ES/SJ2 is available in a choice of 144-pin QFP and LQFP packages.

Samples are available now, with manufacturing volumes scheduled for September 2003.
