V850ES/Jx3-L 32-bit microcontroller family sets new standards in low power consumption
New MCUs require only 0.9 mW/DMIPS of power
The new V850ES/Jx3-L family features extremely low power consumption. The devices set new standards in energy saving; they require only 0.9 mW/DMIPS of power in active mode and draw as little as 1.5 ìA in stop mode.
Despite low power consumption, the V850ES/Jx3-L family makes no compromise on performance or peripherals. The 32 bit microcontrollers are based on the popular V850ES RISC CPU core running at up to 20 MHz and provide either 128KB or 256KB of Flash memory and up to 16KB of embedded RAM. Thanks to their highly efficient pipeline architecture and integrated DSP functions, the devices are capable of high-end mathematical operations.
Moreover, the V850ES/Jx3-L family offers a number of on-chip features, which contribute to reducing component count and system cost whilst simultaneously increasing system reliability. Watchdog, power-on reset and low-voltage detection are standard. Despite low voltage operation of 2.2 V to 3.6 V, the V850ES/Jx3-L family offers 5V-tolerant I/O ports, hence making an additional cost saving on external level shifters.
Furthermore, the new microcontroller family includes seven serial communications channels, which allow a flexible selection of the operating mode and the required functions. Numerous UARTs, I2C interfaces or clocked serial interface (CSI) are available to the user.
Additional features of the V850ES/Jx3-L family include an integrated cyclic redundancy check (CRC) circuit and a hardware multiplier for faster algorithm execution. An external bus interface for additional memory expansion, highly flexible one and three phase 16-bit timers, watch timer, up to 12 channels for A/D conversion and up to two channels for D/A conversion, a DMA controller with four independent DMA channels and on-chip debug functions complete the highly efficient chip design.
The V850ES/Jx3-L family is pin and functional compatible to existing generations of the V850 All Flash range. The 80-pin package and 12 mm2 (LQFP fine pitch) as well as 14 mm2 (standard package) contribute to a reduction in the size of portable equipment. An optional 100-pin version in a 14 mm2 LQFP fine pitch or a 14 x 20 mm package is also available.
In addition to compiler suites from IAR Systems and Green Hills, a number of different tools – including a starter kit MINICUBE2 for on-chip debugging, IECUBE for full trace and emulation and the new PG-FP5 Flash programmer – are available to the user for development. The starter kit and first samples of the V850ES/Jx3L family are available now. Mass production is expected to begin in March of 2008.
