operations of the memory array.
The X76F101 features a serial interface and software protocol allowing operation on a popular two wire bus. The bus signals are a clock Input (SCL) and a bidirectional data input and output (SDA). Access to the device is controlled through a chip select (CS) input, allowing any number of devices to share the same bus. The X76F101 also features a synchronous response to reset providing an automatic output of a hard-wired 32-bit data stream conforming to the industry standard for memory cards.

X76F101
PIN DESCRIPTIONS Serial Clock (SCL)
The SCL input is used to clock all data into and out of the device. To ensure the correct communication, RST must remain LOW under all conditions except when running a "Response to Reset sequence". Data is transferred in 8-bit segments, with each transfer being followed by an ACK, generated by the receiving device. If the X76F101 is in a nonvolatile write cycle a "no ACK" (SDA=High) response will be issued in response to loading of the command byte. If a stop is issued prior to the nonvolatile write cycle the write operation will be terminated and the part will reset and enter into a standby mode. The basic sequence is illustrated in Figure 1.
Serial Data (SDA)
SDA is an open drain serial data input/output pin. During a read cycle, data is shifted out on this pin. During a write cycle, data is shifted in on this pin. In all other cases, this pin is in a high impedance state.
Chip Select (CS)
When CS is high, the X76F101 is deselected and the SDA pin is at high impedance and unless an internal write operation is underway, the X76F101 will be in standby mode. CS low enables the X76F101, placing it in the active mode. Reset (RST) RST is a device reset pin. When RST is pulsed high while CS is low the X76F101 will output 32 bits of fixed data which conforms to the standard for "synchronous response to reset". CS must remain LOW and the part must not be in a write cycle for the response to reset to occur. See Figure 7. If at any time during the response to reset CS goes HIGH, the response to reset will be aborted and the part will return to the standby state. The response to reset is "mask programmable" only!

DEVICE OPERATION
The X76F101 memory array consists of fourteen 8-byte sectors. Read or write access to the array always begins
at the first address of the sector. Read operations then can continue indefinitely. Write operations must total 8

bytes.
There are two primary modes of operation for the X76F101; Protected READ and protected WRITE.
Protected operations must be performed with one of two 8-byte passwords.
The basic method of communication for the device is established by first enabling the device (CS LOW),
generating a start condition, then transmitting a command, followed by the correct password. All parts will be shipped from the factory with all passwords equal to `0'. The user must perform ACK Polling to determine the
validity of the password, before starting a data transfer (see Acknowledge Polling.) Only after the correct
password is accepted and a ACK polling has been performed, can the data transfer occur.

After each transaction is completed, the X76F101 will reset and enter into a standby mode. This will also be the
A start may be issued to terminate the input of a control byte or the input data to be written. This will reset the device and leave it ready to begin a new read or write command. Because of the push/pull output, a start cannot be generated while the part is outputting data. Starts are inhibited while a write is in progress. Stop Condition
response if an unsuccessful attempt is made to access a protected array.
Figure 1. X76F101 Device Operation LOAD COMMAND/ADDRESS BYTE
All communications must be terminated by a stop condition. The stop condition is a LOW to HIGH transition of SDA when SCL is HIGH. The stop condition is also used to reset the device during a command or data input sequence and will leave the device in the standby power mode. As with starts, stops are inhibited when outputting data and while a write is in progress. Acknowledge Acknowledge is a software convention used to indicate successful data transfer. The transmitting device, either master or slave, will release the bus after transmitting eight bits. During the ninth clock cycle the receiver will pull the SDA line LOW to acknowledge that it received the eight bits of data. The X76F101 will respond with an acknowledge after recognition of a start condition and its slave address. If

Device Protocol
The X76F101 supports a bidirectional bus oriented protocol. The protocol defines any device that sends data
both the device and a write condition have been selected, the X76F101 will respond with an acknowledge after the receipt of each subsequent eight-bit word.
onto the bus as a transmitter and the receiving device as a receiver. The device controlling the transfer is a master and the device being controlled is the slave. The master will always initiate data transfers and provide the clock for both transmit and receive operations. Therefore, the X76F101 will be considered a slave in all applications.
Clock and Data Conventions
Data states on the SDA line can change only during SCL LOW. SDA changes during SCL HIGH are reserved for indicating start and stop conditions. Refer to Figure 2 and Figure 3.
Start Condition
All commands are preceded by the start condition, which is a HIGH to LOW transition of SDA when SCL is HIGH. The X76F101 continuously monitors the SDA and SCL lines for the start condition and will not respond to
any command until this condition is met.

Write Read Write Write None
Illegal command codes will be disregarded. The part will respond with a "no-ACK" to the illegal byte and then return to the standby mode. All write/read operations require a password.
PROGRAM OPERATIONS Sector Write
The sector write mode requires issuing the 8-bit write command followed by the password and then the data
issued which starts the nonvolatile write cycle. If more or less than 8 bytes are transferred, the data in the sector
remains unchanged. ACK Polling
Once a stop condition is issued to indicate the end of the host's write sequence, the X76F101 initiates the internal nonvolatile write cycle. In order to take advantage of the typical 5ms write cycle, ACK polling can begin immediately. This involves issuing the start condition
bytes transferred as illustrated in figure 4. The write command byte contains the address of the sector to be
written. Data is written starting at the first address of a sector and eight bytes must be transferred. After the last
byte to be transferred is acknowledged a stop condition is

followed by the new command code of 8 bits (1st byte of the protocol.) If the X76F101 is still busy with the nonvolatile write operation, it will issue a "no-ACK" in response. If the nonvolatile write operation has

READ OPERATIONS
Read operations are initiated in the same manner as write operations but with a different command code.
After the password sequence, there is always a nonvolatile write cycle. This is done to discourage random guesses of the password if the device is being tampered with. In order to continue the transaction, the X76F101
requires the master to perform a password ACK polling sequence with the specific command code of 55h. As with regular Acknowledge polling the user can either time out for 10ms, and then issue the ACK polling once, or
Sector Read
With sector read, a sector address is supplied with the read command. Once the password has been
acknowledged data may be read from the sector. An acknowledge must follow each 8-bit data transfer. A read operation always begins at the first byte in the sector, but may stop at any time. Random accesses to the array are not possible. Continuous reading from the array will return data from successive sectors. After reading the
last sector in the array, the address is automatically set to the first sector in the array and data can continue to be
continuously loop as described in the flow.
If the password that was inserted was correct, then an "ACK" will be returned once the nonvolatile cycle in
response to the password ACK polling sequence is over.
If the password that was inserted was incorrect, then a "no ACK" will be returned even if the nonvolatile cycle is over. Therefore, the user cannot be certain that the password is incorrect until the 10ms write cycle time has
read out. After the last bit has been read, a stop condition is generated without sending a preceding acknowledge.

This conforms to the ISO standard for "synchronous response to reset". CS must remain LOW and the part must not be in a write cycle for the response to reset to occur. After initiating a nonvolatile write cycle the RST pin must not be pulsed until the nonvolatile write cycle is complete.
If not, the ISO response will not be activated. Also, any attempt to pulse the RST pin in the middle of an ISO
