0V/3V/5V for full compatibility with SIM/smart-card specifi-
cations. Figure 2 shows the charge pump for SIM card
applications. Alternatively, the MAX619 generates a regu-
lated 5V from input voltages as low as 2V.
SPI/QSPI/MICROWIRE Interface
The MAX1840/MAX1841 are also useful as 3V/5V level
shifters in SPI, QSPI, and MICROWIRE applications
(Figure 3). On the slave side, connect CLK to SCLK,
RST to
CS
, and IO to DOUT and DIN. The unidirectional
level shifters transfer chip select and clock signals to
the slave device(s), while the bidirectional level shifter
transfers data.
