SPI/MICROWIRE-Compatible UART and ±15kV ESD-
Protected RS-232 Transceivers with Internal Capacitors
SPI Interface
The MAX3110E/MAX3111E are compatible with SPI,
QSPI (CPOL = 0, CPHA = 0), and MICROWIRE serial-
interface standards (Figure 2). The MAX3110E/
MAX3111E have a unique full-duplex-only architecture
that expects a 16-bit word for DIN and simultaneously
produces a 16-bit word for DOUT regardless of which
read/write register is used. The DIN stream is moni-
tored for its first two bits to tell the UART the type of
data transfer being executed (see the
Write
Configuration Register, Read Configuration Register,
Write Data Register, and Read Data Register sections).
DIN (MOSI) is latched on SCLK’s rising edge. DOUT
(MISO) should be read into the P on SCLK’s rising
edge. The first bit (bit 15) of DOUT transitions on CS’s
falling edge, and bits 14–0 transition on SCLK’s falling
edge. Figure 3 shows the detailed serial timing specifi-
cations for the synchronous SPI port.
Only 16-bit words are expected. If CS goes high in the
middle of a transmission (any time before the 16th bit),
the sequence is aborted (i.e., data does not get written
to individual registers). Most operations, such as the
clearing of internal registers, are executed only on CS’s
rising edge. Every time CS goes low, a new 16-bit
stream is expected. An example of using the Write
Configuration Register is shown in Figure 4.
Table 1 describes the bits located in the Write Config-
uration, Read Configuration, Write Data, and Read
Data Registers. This table also describes whether the
bit is a read or a write bit and the power-on reset state
(POR) of the bits. Figure 5 shows an example of parity
and word-length control.
