TI has added a new member to its growing Launchpad family of three MSP430, Tiva-C and C2000. The Hercules Launchpad comes in two flavors – TMS57004  and RM42.  Both are based around the XL format of the Launchpad allowing them to be compatible with 40-pin BoosterPack designs. Hercules MCUs with dual lockstep ARM(R) Cortex(TM) CPUs and advanced integrated safety features are designed for IEC 61508 and ISO 26262 safety-critical applications.
