FM24C64 – 64K-Bit Standard 2-Wire Bus Interface Serial EEPROM

December 2001

General Description

FM24C64 is a 64Kbit CMOS non-volatile serial EEPROM organized as 8K x 8 bit memory. This device confirms to Extended IIC 2-wire protocol that allows accessing of memory in excess of 16Kbit on an IIC bus. This serial communication protocol uses a Clock signal (SCL) and a Data signal (SDA) to synchronously clock data between a master (e.g. a microcontroller) and a slave (EEPROM). FM24C64 is designed to minimize pin count and simplify PC board layout requirements.

FM24C64 offers hardware write protection where by the entire memory array can be write protected by connecting WP pin to VCC. This section of memory then becomes unalterable until the WP pin is switched to VSS.

“LZ” and “L” versions of FM24C64 offer very low standby current making them suitable for low power applications. This device is offered in SO, TSSOP and DIP packages.

Fairchild EEPROMs are designed and tested for applications requiring high endurance, high reliability and low power consumption.

Background Information (IIC Bus)

Extended IIC specification is an extension of Standard IIC specification to allow addressing of EEPROMs with more than 16Kbits of memory on an IIC bus. The difference between the two specifications is that Extended IIC specification defines two bytes of “Array Address” information while Standard IIC specification defines only one. All other aspects are identical between the two specifications. Using two bytes of Array Address and 3 address signals (A2, A1 and A0), it is now possible to address up to 4 Mbits (28 * 28 * 23 * 8 = 4 Mbits) of memory on an IIC bus.

Note that due to format difference, it is not possible to have peripherals which follow Standard IIC specification (e.g. 16K bit EEPROM) and peripherals which follow Extended IIC specification (e.g. 64K bit EEPROM) on a common IIC bus.

IIC bus allows synchronous bi-directional communication between a TRANSMITTER and a RECEIVER using a Clock signal (SCL) and a Data signal (SDA). Additionally there are up to three Address signals (A2, A1 and A0) which collectively serve as “chip select signal” to a device (e.g. EEPROM) on the bus.

All communication on the IIC bus must be started with a valid START condition (by a MASTER), followed by transmittal (by the MASTER) of byte(s) of information (Address/Data). For every byte of information received, the addressed RECEIVER provides a valid ACKNOWLEDGE pulse to further continue the communication unless the RECEIVER intends to discontinue the communication. Depending on the direction of transfer (Write or Read), the RECEIVER can be a SLAVE or the MASTER. A typical IIC communication concludes with a STOP condition (by the MASTER).

Addressing an EEPROM memory location involves sending a command string with the following information:

[DEVICE TYPE]—[DEVICE/PAGE BLOCK SELECTION]—[R/W BIT]—[ARRAY ADDRESS#1]—[ARRAY ADDRESS#0]

Slave Address

Slave Address is an 8-bit information consisting of a Device type field (4bits), Device/Page block selection field (3bits) and Read/ Write bit (1bit).

Slave Address Format

Device Type

IIC bus is designed to support a variety of devices such as RAMs, EPROMs etc., along with EEPROMS. Hence to properly identify various devices on the IIC bus, a 4-bit “Device Type” identifier string is used. For EEPROMS, this 4-bit string is 1-0-1-0. Every IIC device on the bus internally compares this 4-bit string to its own “Device Type” string to ensure proper device selection.

Device/Page Block Selection

When multiple devices of the same type (e.g. multiple EEPROMS) are present on the IIC bus, then the A2, A1 and A0 address information bits are used in device selection. Every IIC device on the bus internally compares this 3-bit string to its own physical configuration (A2, A1 and A0 pins) to ensure proper device selection. This comparison is in addition to the “Device Type” comparison.

In addition to selecting an EEPROM, these 3 bits are also used to select a “page block” within the selected EEPROM. Each page block is 512Kbit (64 K Bytes) in size. If an EEPROM contains more than one page bock then the selection of a page block within the EEPROM is by using A2, A1 and A0 bits.

Read/Write Bit

Last bit of the Slave Address indicates if the intended access is Read or Write. If the bit is "1," then the access is Read, whereas if the bit is "0," then the access is Write.

Acknowledge

Acknowledge is an active LOW pulse on the SDA line driven by an addressed receiver to the addressing transmitter to indicate receipt of 8-bits of data. The receiver provides an ACK pulse for every 8-bits of data received. This handshake mechanism is done as follows: After transmitting 8-bits of data, the transmitter releases the SDA line and waits for the ACK pulse. The addressed receiver, if present, drives the ACK pulse on the SDA line during the 9th clock and releases the SDA line back (to the transmitter). Refer

Pin Descriptions

Serial Clock (SCL)

The SCL input is used to clock all data into and out of the device.

Serial Data (SDA)

SDA is a bi-directional pin used to transfer data into and out of the device. It is an open drain output and may be wire–ORed with any number of open drain or open collector outputs.

Write Protect (WP)

If tied to VCC, PROGRAM operations onto the entire memory will not be executed. READ operations are possible. If tied to VSS, normal operation is enabled, READ/WRITE over the entire memory is possible.

This feature allows the user to assign the entire memory as ROM which can be protected against accidental programming. When write is disabled, slave address and word address will be acknowledged but data will not be acknowledged.

This pin has an internal pull-down circuit. However, on systems where write protection is not required it is recommended that this pin is tied to VSS.

Device Selection Inputs A2, A1 and A0 (as appropriate)

These inputs collectively serve as “chip select” signal to an EEPROM when multiple EEPROMs are present on the same IIC bus. Hence these inputs should be connected to VCC or VSS in a unique manner to allow proper selection of an EEPROM amongst multiple EEPROMs. During a typical addressing sequence, every EEPROM on the IIC bus compares the configuration of these inputs to the respective 3 bit “Device/Page block selection” information (part of slave address) to determine a valid selection. For e.g. if the 3 bit “Device/Page block selection” is 1-0-1, then the EEPROM whose “Device Selection inputs” (A2, A1 and A0) are connected to VCC-VSS-V

respectively, is selected.

Device Operation

The FM24C64 supports a bi-directional bus oriented protocol. The protocol defines any device that sends data onto the bus as a transmitter and the receiving device as the receiver. The device controlling the transfer is the master and the device that is controlled is the slave. The master will always initiate data transfers and provide the clock for both transmit and receive operations. Therefore, the FM24C64 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 state changes during SCL HIGH are reserved for indicating start and stop conditions. Refer

Figure 1

Start Condition

All commands are preceded by the start condition, which is a HIGH to LOW transition of SDA when SCL is HIGH. The FM24C64 continuously monitors the SDA and SCL lines for the start condition and will not respond to any command until this condition has been met. Refer

Figure 2

Stop Condition

All communications are terminated by a stop condition, which is a LOW to HIGH transition of SDA when SCL is HIGH. The stop condition is also used by the FM24C64 to place the device in the standby power mode. Refer

Figure 2

FM24C64 Array Addressing

During Read/Write operations, addressing the EEPROM memory array involves in providing 2 address bytes, “Word Address 1” and “Word Address 0." However on FM24C64 only the 5 least significant bits (LSB) of “Word Address 1” byte are used in decoding the access location. The remaining 3 bits are not used and are recommended to be set to “0." All 8 bits of the “Word Address 0” byte are used in decoding the access location.

Write Operations

BYTE WRITE

For byte write operation, two bytes of address are required after the slave address. These two bytes select 1 out of the 8192 locations in the memory. The master provides these two address bytes and for each address byte received, FM24C64 responds with an acknowledge pulse. Master then provides a byte of data to be written into the memory. Upon receipt of this data, FM24C64 responds with an acknowledge pulse. The master then terminates the transfer by generating a stop condition, at which time the FM24C64 begins the internal write cycle to the memory. While the internal write cycle is in progress the FM24C64 inputs are disabled, and the device will not respond to any requests from the master for the duration of t acknowledge and data transfer sequence.

PAGE WRITE

To minimize write cycle time, FM24C64 offers Page Write feature, which allows simultaneous programming of up to 32 contiguous bytes. To facilitate this feature, the memory array is organized in terms of “Pages”. A Page consists of 32 contiguous byte locations starting at every 32-Byte address boundary (for example, starting at array address 0x0000, 0x0020, 0x0040 etc.). Page Write operation is confined to a single page. In other words a Page Write operation will not cross over to locations on the next page but will “roll over” to the beginning of the same page whenever end of page is reached and additional data bytes are a continued to be provided. A Page Write operation can be initiated to begin at any location within a page (starting address of the Page Write operation need not be the starting address of a Page).

. Refer Figure 4 for the address,

Page Write is initiated in the same manner as the Byte Write operation; but instead of terminating the cycle after transmitting the first data byte, the master can further transmit up to 31 more bytes. After the receipt of each byte, FM24C64 will respond with an acknowledge pulse, increment the internal address counter to the next address, and is ready to accept the next data. If the master should transmit more than 32 bytes prior to generating the STOP condition, the address counter will “roll over” and previously loaded data will be re-loaded. As with the Byte Write operation, all inputs are disabled until completion of the internal write cycle.

Figure 5

Refer

for the address, acknowledge, and data transfer

sequence.

Acknowledge Polling

Once the stop condition is issued to indicate the end of the host’s write operation, the FM24C64 initiates the internal write cycle. ACK polling can be initiated immediately. This involves issuing the start condition followed by the slave address for a write operation. If the FM24C64 is still busy with the write operation, no ACK will be returned. If the FM24C64 has completed the write operation, an ACK will be returned and the host can then proceed with the next read or write operation.

Write Protection

Programming of the entire memory will not take place if the WP pin of the FM24C64 is connected to VCC. The FM24C64 will respond to slave and byte addresses; but if the memory accessed is write protected by the WP pin, the FM24C64 will not generate an acknowledge after the first byte of data has been received. Thus the program cycle will not be started when the stop condition is asserted.

Read Operations

Read operations are initiated in the same manner as write operations, with the exception that the R/W bit of the slave address is set to a one. There are three basic read operations: current address read, random read, and sequential read.

Current Address Read

Internally the FM24C64 contains an address counter that maintains the address of the last byte accessed, incremented by one. Therefore, if the last access (either a read or write) was to address n, the next read operation would access data from address n + 1. Upon receipt of the slave address with R/W set to "1," the FM24C64 issues an acknowledge and transmits the eight bit word. The master will not acknowledge the transfer but does generate a stop condition, and therefore the FM24C64 discontinues transmission. Refer acknowledge and data transfer.

Random Read

Random read operations allow the master to access any memory location in a random manner. Prior to issuing the slave address with the R/W bit set to "1," the master must first perform a “dummy” write operation. The master issues the start condition, slave address with the R/W bit set to "0" and then the byte address. After the byte address acknowledge, the master immediately issues another start condition and the slave address with the R/W bit set to one. This will be followed by an acknowledge from the FM24C64 and then by the eight bit word. The master will

for the sequence of address,

not acknowledge the transfer but does generate the stop condition, and therefore the FM24C64 discontinues transmission. Refer

Figure 7

for the address, acknowledge, and data transfer

sequence.

Sequential Read

Sequential reads can be initiated as either a current address read or random access read. The first word is transmitted in the same manner as the other read modes; however, the master now responds with an acknowledge, indicating it requires additional data. The FM24C64 continues to output data for each acknowledge received. The read operation is terminated by the master not responding with an acknowledge or by generating a stop condition.

The data output is sequential with the data from address n followed by the data from n + 1. The address counter for read operations increments all word address bits, allowing the entire memory contents to be serially read during one operation. After the entire memory has been read, the counter "rolls over" to the beginning of the memory. FM24C64 continues to output data for each acknowledge received. Refer acknowledge, and data transfer sequence.
