TS4031

Radiation-Hardened 64-ch GPIO, 32-ch 10-bit ADC

Triad Semiconductor’s TS4031 is a highly integrated, general purpose IC for space applications. It combines two basic building blocks required for a general-purpose system: measuring analog voltages from the various system sensors and driving-receiving up to 64 digital IO signals. The analog sensing block is comprised of a 32-1 analog mux and a 10-bit Pipeline ADC with two on-chip references (bandgap and DTMOS) and one off-chip reference input. The digital block is comprised of 64 General Purpose IO’s and a SPI Bus for reading and writing registers from the processor. The TS4301 is available in a 144-pin BGA package (13mm x 13mm, 0.4mm pitch). The device operates from +3.0V to +3.6V and 1.62V to 1.98V supply inputs and is specified over a -55oC to +85oC operating temperature range.
