Data Sheet
I
With CS tied high to V
requiring a simple 2-wire connection as shown in Figure 55.
The
and User Manual, Rev. 03—19 June 2007, available from NXP
Semiconductor. It supports standard (100 kHz) and fast (400 kHz)
data transfer modes if the timing parameters given in Table 12
and Figure 57 are met.
Single-byte or multiple-byte reads/writes are supported,
as shown in Figure 56. With the SDO/ALT ADDRESS pin
(Pin 7) high, the 7-bit I
by the R/ W bit. This translates to 0x3A for a write and 0x3B for a
read. An alternate I
can be chosen by grounding the SDO/ALT ADDRESS pin
(Pin 7). This translates to 0xA6 for a write and 0xA7 for a read.
