Ti dropped a new launchpad today, it isn't even listed on the ti.com/launchpad page.
From the email:
"the world’s first microcontroller (MCU) with a configurable low-leakage transimpedance amplifier (TIA). The MSP430FR2311 MCU features the industry’s only integrated TIA with 50pA current leakage, more than 20x lower leakage than alternative voltage and current sensing solutions.
Connect to any sensor with non-inverting, inverting and transimpedance operational amplifier configurations and eliminate the boundaries of Flash to RAM ratios, taking advantage of the greater flexibility the MSP430FR2311 MCU provides your designs."
