N55S016
16M-BIT Low Voltage, Serial MASK ROM
with 50MHz SPI Bus Interface
GENERAL DESCRIPTION
The N55S016 is a 16Mbit (2M Bytes) Serial Mask ROM accessed by a high speed Serial peripheral interface.
KEY FEATURES
• Operating voltage ranges from 3.0V to 3.6V
• Serial Peripheral Interface compatible-mode 0 and 3
• High performance: "fast read" mode at 50MHz and "normal read" at 20MHz
• Low power consumption: 8mA for fast read mode or 4mA for normal read mode
• Low standby current: 15uA

DEVICE
OPERATION
Stand-by Mode
When incorrect command is inputted to this LSI, this LSI becomes standby mode and keeps in standby mode
until next CS# falling edge. In standby mode, SO pin of this LSI should be High-Z.
Active Mode
When correct command is inputted to this LSI, this LSI becomes active mode and keeps the active mode until
next
CS# rising edge.
SPI Feature
Input data is latched on the rising edge of Serial Clock(SCLK) and data shifts out on the falling edge of SCLK.
The difference of SPI mode 0 and mode 3 is shown as Figure 1.

Note:
CPOL indicates clock polarity of SPI master, CPOL=1 for SCLK high while idle, CPOL=0 for SCLK low
while not transmitting. CPHA indicates clock phase. The combination of CPOL bit and CPHA bit decides
which SPI mode is supported.
