Memory-hungry embedded applications and EMI-sensitive applications are specially catered for by the latest S-Line range of RISC based microcontrollers from Sunrise Electronics.

Memory-hungry embedded applications and EMI-sensitive applications are specially catered for by the latest S-Line range of RISC based microcontrollers from Sunrise Electronics.

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

Together with CANless 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/SG2 offers a wide variety of memory configurations with high densities in various combinations from 256Kbyte ROM and 24Kbyte RAM up to 640Kbyte ROM and 48Kbyte RAM.

The V850ES/SG2 supports a host of onboard peripherals and an optional FCAN interface.

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

Features of the V850ES/SG2 include a 32bit RISC CPU operating at 20MHz giving a 50ns minimum instruction execution time.

On-chip facilities include 84 I/Os, three standard UARTs, five three-wire serial interfaces (CSI), a 12-channel A/D convertor with 10bit resolution, two channels of D/A convertor with 8bit resolution, eight 16bit timers plus a watch timer and watchdog timer.

It supports nine channels of 16bit PWM and has optional I2C and FCAN buses.

The V850ES/SJ2 adds even more functionality with higher I/O count and an optional second CAN interface.

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/SG2 is available now in a choice of 100-pin QFP and LQFP packages.
