Part Number | 33975A |
Manufacturer | Freescale Semiconductor |
Description | of each terminal can be found in the Functional Terminal Description section on page 11. Terminal 1 2 3 4 5–8 25–28 9–15, 18–24 16 17 29 30 31 32 Terminal Name GND SI SCLK CS SPn SGn VPWR WAKE INT AMUX VDD SO Formal Name Ground SPI Slave In Serial Clock Chip Select Programmable Switches 0–3 Programmable Switches 4–7 Switch-to-Ground Inputs 0–6 Switch-to-Grou. |
Features | a 22-to-1 analog multiplexer for reading inputs as analog. The 33975 device has two modes of operation, Normal and Sleep. Normal mode allows programming of the device and supplies switch contacts with pull-up or pull-down current as it monitors switch change of state. The Sleep mode provides low quiescent current, which makes the 33975 ideal for automotive and industrial products requiring low sleep state currents. Improvements are a programmable interrupt timer for Sleep mode that can be disabled, switch detection currents of 32 mA and 4.0 mA for switch-to-ground inputs, and an interrupt bit . |
