CY62167DV30 MoBL®
16-Mbit (1 M × 16) Static RAM
16-Mbit (1
M × 16) Static RAM
automatic power-down feature that significantly reduces power
consumption by 99% when addresses are not toggling. The
device can also be put into standby mode when deselected (CE1
HIGH or CE2 LOW or both BHE and BLE are HIGH). The
Features
■ Thin small outline package (TSOP-I) configurable as
1 M × 16 or as 2 M × 8 SRAM
input/output pins (I/O0 through I/O15
) are placed in a
■ Wide voltage range: 2.2 V–3.6 V
high-impedance state when: deselected (CE1 HIGH or CE2
LOW), outputs are disabled (OE HIGH), both Byte High Enable
and Byte Low Enable are disabled (BHE, BLE HIGH), or during
a Write operation (CE1 LOW, CE2 HIGH and WE LOW).
■ Ultra-low active power:
Typical active current: 2 mA at f = 1 MHz
■ Ultra-low standby power
Writing to the device is accomplished by taking Chip Enables
(CE1 LOW and CE2 HIGH) and Write Enable (WE) input LOW. If
Byte Low Enable (BLE) is LOW, then data from I/O pins (I/O0
through I/O7), is written into the location specified on the address
pins (A0 through A19). If Byte High Enable (BHE) is LOW, then
data from I/O pins (I/O8 through I/O15) is written into the location
specified on the address pins (A0 through A19).
■ Easy memory expansion with CE1, CE2 and OE features
■ Automatic power-down when deselected
■ Complementary metal oxide semiconductor (CMOS) for
optimum speed / power
■ Available in Pb-free and non Pb-free 48-ball very fine-pitch ball
grid array (VFBGA) and 48-pin TSOP I package
Reading from the device is accomplished by taking Chip Enables
(CE1 LOW and CE2 HIGH) and Output Enable (OE) LOW while
forcing the Write Enable (WE) HIGH. If Byte Low Enable (BLE)
is LOW, then data from the memory location specified by the
address pins appear on I/O0 to I/O7. If Byte High Enable (BHE)
is LOW, then data from memory appear on I/O8 to I/O15. See the
truth table at the back of this data sheet for a complete
description of Read and Write modes.
Functional Description
The CY62167DV30 is a high-performance CMOS static RAM
organized as 1M words by 16-bits. This device features
