V850ES is a line of high performance 32-bit microcontrollers that is
energy efficient and available in small packages. The V850ES core is
an enhanced 5-stage pipeline that achieves more processing per clock
cycle. V850ES microcontrollers employ Flash memory with Error Correction 
Code that corrects a bit error. With the enhanced reliability, there
 has never been a Flash retention failure. In addition, the V850ES 
Flash has different level of security to protect the software, 
safeguarding from tampering.

V850 microcontrollers supports a Bootswap mechanism to ensure fail-safe 
firmware update even during power failure. The Watch Dog Timer uses an 
Internal, dedicated oscillator.
