The memory is organized as 128 K bytes of 8 bits each or 64 K words of 16 bits each. The embedded nonvolatile elements incorporate QuantumTrap technology, producing the world's most reliable nonvolatile memory. The SRAM provides infinite read and write cycles, while independent nonvolatile data resides in the highly reliable QuantumTrap cell. 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.

Document Number: 001-42879 Rev. *R Page 5 of 30 CY14B101LA CY14B101NA The CY14B101LA/CY14B101NA nvSRAM is made up of two functional components paired in the same physical cell. They 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), or from the nonvolatile cell to the SRAM (the RECALL operation). 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 CY14B101LA/CY14B101NA supports infinite reads and writes similar to a typical SRAM. In addition, it provides infinite RECALL operations from the nonvolatile cells and up to 1 million STORE operations. See the Truth Table For SRAM Operations on page 18 for a complete description of read and write modes. SRAM Read The CY14B101LA/CY14B101NA performs a read cycle when CE and OE are LOW and WE and HSB are HIGH. The address specified on pins A0-16 or A0-15 determines which of the 131,072 data bytes or 65,536 words of 16 bits each are accessed. Byte enables (BHE, BLE) determine which bytes are enabled to the output, in the case of 16-bit words. When the read is initiated by an address transition, the outputs are valid after a delay of tAA (read cycle 1). If the read is initiated by CE or OE, the outputs are valid at tACE or at tDOE, whichever is later (read cycle 2). The data output repeatedly responds to address changes within the tAA access time without the need for transitions on any control input pins. This remains valid until another address change or until CE or OE is brought HIGH, or WE or HSB is brought LOW. SRAM Write A write cycle is performed when CE and WE are LOW and HSB is HIGH. The address inputs must be stable before entering the write cycle and must remain stable until CE or WE goes HIGH at the end of the cycle. The data on the common I/O pins DQ0-15 are written into the memory if the data is valid tSD before the end of a WE-controlled write or before the end of a CE-controlled write. The Byte Enable inputs (BHE, BLE) determine which bytes are written, in the case of 16-bit words. Keep OE HIGH during the entire write cycle to avoid data bus contention on common I/O lines. If OE is left LOW, internal circuitry turns off the output buffers tHZWE after WE goes LOW. AutoStore Operation The CY14B101LA/CY14B101NA stores data to the nvSRAM using one of the following three storage operations: Hardware STORE activated by HSB; Software STORE activated by an address sequence; AutoStore on device power-down. The AutoStore operation is a unique feature of QuantumTrap technology and is enabled by default on the CY14B101LA/CY14B101NA. During a 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 single STORE operation. If the voltage on the VCC pin drops below VSWITCH, the part automatically disconnects the VCAP pin from VCC. A STORE operation is initiated with power provided by the VCAP capacitor. Note If the capacitor is not connected to VCAP pin, AutoStore must be disabled using the soft sequence specified in Preventing AutoStore on page 8. In case AutoStore is enabled without a capacitor on VCAP pin, the device attempts an AutoStore operation without sufficient charge to complete the store. This corrupts the data stored in nvSRAM. Figure 4 shows the proper connection of the storage capacitor (VCAP) for automatic STORE operation. See the DC Electrical Characteristics on page 9 for the size of VCAP. The voltage on the VCAP pin is driven to VCC by a regulator on the chip. A pull-up should be placed on WE to hold it inactive during power-up. This pull-up is effective only if the WE signal is tristate during power-up. Many MPUs tristate their controls on power-up. This should be verified when using the pull-up. When the nvSRAM comes out of power-on-RECALL, the MPU must be active or the WE held inactive until the MPU comes out of reset. To reduce unnecessary nonvolatile stores, AutoStore and Hardware STORE operations are ignored unless at least one write operation has taken place since the most recent STORE or RECALL cycle. Software initiated STORE cycles are performed regardless of whether a write operation has taken place. The HSB signal is monitored by the system to detect if an AutoStore cycle is in progress. Figure 4. AutoStore Mode VCC 0.1 uF 10 kOhm Device Operation VCC WE VCAP VSS VCAP Hardware STORE Operation The CY14B101LA/CY14B101NA provides the HSB[14] pin to control and acknowledge the STORE operations. Use the HSB pin to request a Hardware STORE cycle. When the HSB pin is driven LOW, the CY14B101LA/CY14B101NA conditionally initiates a STORE operation after tDELAY. An actual STORE cycle only begins if a write to the SRAM has taken place since the last STORE or RECALL cycle. The HSB pin also acts as an open drain driver (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. 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 internal 100 k pull-up resistor. Note 14. HSB pin is not available in 44-pin TSOP II (x 16) package. Document Number: 001-42879 Rev. *R Page 6 of 30 CY14B101LA CY14B101NA SRAM write operations that are in progress when HSB is driven LOW by any means are given time (tDELAY) to complete before the STORE operation is initiated. However, any SRAM write cycles requested after HSB goes LOW are inhibited until HSB returns HIGH. In case the write latch is not set, HSB is not driven LOW by the CY14B101LA/CY14B101NA. But any SRAM read and write cycles are inhibited until HSB is returned HIGH by MPU or other external source. During any STORE operation, regardless of how it is initiated, the CY14B101LA/CY14B101NA 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 time after HSB pin returns HIGH. Leave the HSB unconnected if it is not used. Hardware RECALL (Power-up) 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. Software STORE Data is transferred from the SRAM to the nonvolatile memory by a software address sequence. The CY14B101LA/CY14B101NA Software STORE cycle is initiated by executing sequential CE or OE controlled read cycles from six specific address locations in exact order. During the STORE cycle an erase of the previous nonvolatile data is first performed, followed by a program of the nonvolatile elements. After a STORE cycle is initiated, further input and output are disabled until the cycle is completed. 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, or the sequence is aborted and no STORE or RECALL takes place. 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 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 SRAM is activated again for the read and write operation. 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, the following sequence of CE or OE controlled read operations 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 0x4C63 Initiate RECALL cycle Internally, RECALL is a two step procedure. First, the SRAM data is cleared. Next, the nonvolatile information is transferred into the SRAM cells. After the tRECALL cycle time, the SRAM is again ready for read and write operations. The RECALL operation does not alter the data in the nonvolatile elements. Table 1.

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: 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 0x8B45 AutoStore Disable The AutoStore is reenabled by initiating an AutoStore enable sequence. A sequence of read operations is performed in a manner similar to the Software RECALL initiation. To initiate the AutoStore enable sequence, the following sequence of CE or OE controlled read operations 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 0x4B46 AutoStore Enable If the AutoStore function is disabled or reenabled, a manual STORE operation (Hardware or Software) must be issued to save the AutoStore state through subsequent power-down cycles. The part comes from the factory with AutoStore enabled and 0x00 written in all cells. Data Protection The CY14B101LA/CY14B101NA protects data from corruption during low voltage conditions by inhibiting all externally initiated STORE and write operations. The low voltage condition is detected when VCC is less than VSWITCH. If the CY14B101LA/CY14B101NA is in a write mode (both CE and WE are LOW) at power-up, after a RECALL or STORE, the write is inhibited until the SRAM is enabled after tLZHSB (HSB to output active). This protects against inadvertent writes during power-up or brown out conditions. Note 18. The six consecutive address locations must be in the order listed. WE must be HIGH during all six cycles to enable a nonvolatile cycle.
