Calculations
lAcquisition every 40μs:
è25 KHz
è16 Ion. Chambers per Card.
è8 bit values
l1024K x 36bit SRAM can hold 10.24s of data
èWrite Clock = 400 KHz & Read Clock = 2.4 MHz
è10 seconds need 250K x 8bit per Ion. Chamber.
lAcquisition every 90μs (1 turn):
è11 KHz
è16 Ion. Chambers per Card.
è8 bit values
l1024K x 36bit SRAM can hold 23.04s of data
èWrite Clock = 180 KHz & Read Clock = 1.1 MHz
è10 seconds need 110K x 8bit per Ion. Chamber.
*Note that 2 SRAMs can be available
to keep the data under manipulation and 1 SRAM for PM.
