NX26F160
The NX26F080A and NX26F160 is available in a 24/28-pin
TSOP (Type II) package (Figure 1 and Table 1) or a
removable Serial Flash Module (see NX25Mxxx/NX26Mxxx
Serial Flash Module data sheet for further information).
The NX26F080A and NX26F160 support single power supply
Read, Erase, and Write operations available in 5V and 3V Vcc
versions. Active power requirements are as low as 15 mA for
3V versions with standby current in the 1
The 2-wire NXS (NexFlash Serial) interface includes a
Clock Input pin (SCK) and a single bidirectional I/O pin for
data (SIO). All data to or from the SIO pin is clocked
relative to the rising edge of SCK. The 2-wire NXS serial
interface makes the NX26F080A and NX26F160 an ideal
solution for removable non-volatile storage. A simple edge
connector or cable/connector with four contacts (SCK,
SIO, Vcc, and GND) can support communications with
space efficiency and reliability. The NXS interface can
operate at clock rates up to 16 MHz for 5V versions.
There is no active chip select on the NX26F080A and
NX26F160. Instead, four static device address pins
(A0, A1, A2, and A3) are provided for decoding from one to
16 possible devices (Figure 2). This allows up to 16MB
(using an NX26F080A device) or 32MB (using an NX26F160
device) to be addressed via a single 2-wire NXS interface.
The static address pins (A0-A3) must be tied high or low to
match the device address field (DA3-DA0) in the sector
Read and Erase/Write instruction sequences.
The NX26F080A and NX26F160 uses only a few signal
pins. As a result, the TSOP package has numerous
no connects (NC) that have no electrical contact to the die.
