Functional Description
The Cypress CY14X116L/CY14X116N/CY14X116S is a fast
SRAM, with a nonvolatile element in each memory cell. The
memory is organized as 2048K bytes of 8 bits each or 1024K
words of 16 bits each or 512K words of 32 bits each. The
embedded nonvolatile elements incorporate QuantumTrap
technology, producing the world’s most reliable nonvolatile
memory. The SRAM can be read and written an infinite number
of times. The nonvolatile data residing in the nonvolatile
elements do not change when data is written to the SRAM. Data
transfers from the SRAM to the nonvolatile elements (the
STORE operation) takes place automatically at power-down. On
power-up, data is restored to the SRAM (the RECALL operation)
from the nonvolatile memory. Both the STORE and RECALL
operations are also available under software control.
■ High reliability
❐ Infinite read, write, and RECALL cycles
❐ 1 million STORE cycles to QuantumTrap
❐ Data retention: 20 years
■ Sleep mode operation
■ Low power consumption
❐ Active current of 75 mA at 45 ns
❐ Standby mode current of 650 A
❐ Sleep mode current of 10 A
■ Operating voltages:
❐ CY14B116X: VCC = 2.7 V to 3.6 V
❐ CY14E116X: VCC = 4.5 V to 5.5 V

CY14B116L/CY14B116N/CY14B116S
CY14E116L/CY14E116N/CY14E116S
AutoStore Operation (Power-Down)
Device Operation
The CY14X116L/CY14X116N/CY14X116S stores data to the
nonvolatile QuantumTrap cells using one of the three storage
operations. These three operations are: Hardware STORE,
activated by the HSB; Software STORE, activated by an address
sequence; AutoStore, on device power-down. The AutoStore
operation is a unique feature of nvSRAM and is enabled by
default on the CY14X116L/CY14X116N/CY14X116S.
The CY14X116L/CY14X116N/CY14X116S nvSRAM is made up
of two functional components paired in the same physical cell.
These are an SRAM memory cell and
a nonvolatile
QuantumTrap cell. The SRAM memory cell operates as a
standard fast static RAM. Data in the SRAM is transferred to the
nonvolatile cell (the STORE operation) automatically at
power-down, or from the nonvolatile cell to the SRAM (the
RECALL operation) on power-up. Both the STORE and RECALL
operations are also available under software control. Using this
unique architecture, all cells are stored and recalled in parallel.
During the STORE and RECALL operations, SRAM read and
write operations are inhibited. The CY14X116L/CY14X116N/
CY14X116S supports infinite reads and writes to the SRAM. In
addition, it provides infinite RECALL operations from the nonvol-
atile cells and up to 1 million STORE operations. See the Truth
Table For SRAM Operations on page 24 for a complete
description of read and write modes.
During normal operation, the device draws current from VCC to
charge a capacitor connected to the VCAP pin. This stored
charge is used by the chip to perform a STORE operation during
power-down. If the voltage on the VCC pin drops below VSWITCH
,
the part automatically disconnects the VCAP pin from VCC and a
STORE operation is initiated with power provided by the VCAP
capacitor.
Note If the capacitor is not connected to the VCAP pin, AutoStore
must be disabled using the soft sequence specified in the section
Preventing AutoStore on page 12. If AutoStore is enabled without
a capacitor on the VCAP pin, the device attempts an AutoStore
SRAM Read
operation without sufficient charge to complete the STORE. This
corrupts the data stored in the nvSRAM.
The CY14X116L/CY14X116N/CY14X116S performs a read
cycle whenever CE and OE are LOW, and WE, ZZ, and HSB are
HIGH. The address specified on pins A0–A20 or A0–A19 or

Electrical Characteristics on page 13 for the size of the VCAP. The
voltage on the VCAP pin is driven to VVCAP by a regulator on the
chip. A pull-up resistor should be placed on WE to hold it inactive
during power-up. This pull-up resistor is only effective if the WE
signal is in tristate during power-up. When the nvSRAM comes

STORE cycle, the previous nonvolatile data is first erased,
followed by a store into the nonvolatile elements. After a STORE
cycle is initiated, further reads and writes are disabled until the
cycle is completed.
Hardware STORE (HSB) Operation
The CY14X116L/CY14X116N/CY14X116S provides the HSB pin
to control and acknowledge the STORE operations. The HSB pin
is used to request a Hardware STORE cycle. When the HSB pin
is driven LOW, the device conditionally initiates a STORE
operation after tDELAY. A STORE cycle begins only if a write to
Because a sequence of reads from specific addresses is used
for STORE initiation, it is important that no other read or write
accesses intervene in the sequence. Otherwise, the sequence is
aborted and no STORE or RECALL takes place.
the SRAM has taken place since the last STORE or RECALL
cycle. The HSB pin also acts as an open drain driver (an internal
100-k weak pull-up resistor) that is internally driven LOW to
indicate a busy condition when the STORE (initiated by any
means) is in progress.
To initiate the Software STORE cycle, the following read
sequence must be performed:
1. Read address 0x4E38 Valid Read
2. Read address 0xB1C7 Valid Read
3. Read address 0x83E0 Valid Read
4. Read address 0x7C1F Valid Read
5. Read address 0x703F Valid Read
6. Read address 0x8FC0 Initiate STORE cycle
Note After each Hardware and Software STORE operation, HSB
is driven HIGH for a short time (tHHHD) with standard output high
current and then remains HIGH by an internal 100-k pull-up
resistor.
SRAM write operations that are in progress when HSB is driven
LOW by any means are given time (tDELAY) to complete before
The software sequence may be clocked with CE-controlled
reads or OE-controlled reads, with WE kept HIGH for all the six
read sequences. After the sixth address in the sequence is
entered, the STORE cycle commences and the chip is disabled.
HSB is driven LOW. After the tSTORE cycle time is fulfilled, the
the STORE operation is initiated. However, any SRAM write
cycles requested after HSB goes LOW are inhibited until HSB
returns HIGH. If the write latch is not set, HSB is not driven LOW
by the device. However, any of the SRAM read and write cycles
are inhibited until HSB is returned HIGH by the host microcon-
troller or another external source.
SRAM is activated again for the read and write operation.
During any STORE operation, regardless of how it is initiated,
the device continues to drive the HSB pin LOW, releasing it only
when the STORE is complete. Upon completion of the STORE
operation, the nvSRAM memory access is inhibited for tLZHSB
Software RECALL
Data is transferred from the nonvolatile memory to the SRAM by
a software address sequence. A software RECALL cycle is
initiated with a sequence of read operations in a manner similar
to the Software STORE initiation. To initiate the RECALL cycle,
perform the following sequence of CE or OE controlled read
operations:
time after the HSB pin returns HIGH. Leave the HSB uncon-
nected if it is not used.
Hardware RECALL (Power-Up)
1. Read address 0x4E38 Valid Read
2. Read address 0xB1C7 Valid Read
3. Read address 0x83E0 Valid Read
4. Read address 0x7C1F Valid Read
5. Read address 0x703F Valid Read
6. Read address 0x4C63 Initiate RECALL cycle
During power-up or after any low-power condition
(VCC < VSWITCH), an internal RECALL request is latched. When
VCC again exceeds the VSWITCH on power-up, a RECALL cycle
is automatically initiated and takes tHRECALL to complete. During
this time, the HSB pin is driven LOW by the HSB driver and all
reads and writes to nvSRAM are inhibited.
Internally, RECALL is a two-step procedure. First, the SRAM
data is cleared; then, the nonvolatile information is transferred
into the SRAM cells. After the tRECALL cycle time, the SRAM is

Data is transferred from the SRAM to the nonvolatile memory by

If the AutoStore function is disabled or re-enabled, a manual
software STORE operation must be performed to save the
AutoStore state through subsequent power-down cycles. The
part comes from the factory with AutoStore enabled and 0x00

Preventing AutoStore
The AutoStore function is disabled by initiating an AutoStore
disable sequence. A sequence of read operations is performed
in a manner similar to the Software STORE initiation. To initiate
the AutoStore disable sequence, the following sequence of CE
or OE controlled read operations must be performed:

49. The software sequence is clocked with CE controlled or OE controlled reads.
50. The six consecutive addresses must be read in the order listed in Table 1. WE must be HIGH during all six consecutive cycles.
51. This is the amount of time it takes to take action on a soft sequence command. Vcc power must remain high to effectively register command.
52. Commands such as STORE and RECALL lock out I/O until operation is complete which further increases this time. See the specific command.
53. TSOP II package is offered in single CE. TSOP I and BGA packages are offered in dual CE options. In this datasheet, for a dual CE device, CE refers to the internal
