The TRNG9880 is a random number generator for embedded systems. Output is a logic signal controlled by an external clock signal. The unit provide status and error messages on an UART port, in ASCII text format, to provide easy diagnostics and testing. Both the analogue noise signal and the sampled unprocessed digital signal is externally accessible to facilitate easy diagnostics and testing.
Power 3V-5V (-5%,+10%); size 28mm, 14mm, 3.5mm. Bottom/solder size of the module is green, and on top a yellow metal shielding can. The can is soldered onto the board.
Each unit is subject to extensive testing. Read about the tests in Testing of the TRNG9880.pdf.
