Description:

The Microchip Technology Inc. 24AA64F/24LC64F/

24FC64F (24XX64F*) is a 64 Kbit Electrically Erasable

PROM. The device is organized as a single block of

8K x 8-bit memory with a 2-wire serial interface. Low-

voltage design permits operation down to 1.7V, with

standby and read currents of only 1 A and 400 A,

respectively. It has been developed for advanced, low-

power applications such as personal communications

or data acquisition. The 24XX64F also has a page

write capability for up to 32 bytes of data. Functional

address lines allow up to eight devices on the same

bus, for up to 512 Kbits address space. The 24XX64F

is available in the standard 8-pin PDIP, surface mount

SOIC, TSSOP, TDFN and MSOP packages. The

24XX64F is also available in the 5-lead SOT-23

package.

24AA64F/24LC64F/24FC64F 4.0 BUS CHARACTERISTICS The following bus protocol has been defined: • Data transfer may be initiated only when the bus is not busy • During data transfer, the data line must remain stable whenever the clock line is high. Changes in the data line while the clock line is high will be interpreted as a Start or Stop condition The data on the line must be changed during the low period of the clock signal. There is one clock pulse per bit of data.
PAGE 7
24AA64F/24LC64F/24FC64F 5.0 DEVICE ADDRESSING FIGURE 5-1: A control byte is the first byte received following the Start condition from the master device (Figure 5-1). The control byte consists of a four-bit control code. For the 24XX64F, this is set as ‘1010’ binary for read and write operations. The next three bits of the control byte are the Chip Select bits (A2, A1, A0). The Chip Select bits allow the use of up to eight 24XX64F devices on the same bus and are used to select which device is accessed.
PAGE 8
24AA64F/24LC64F/24FC64F 6.0 WRITE OPERATIONS 6.1 Byte Write Following the Start condition from the master, the control code (four bits), the Chip Select (three bits) and the R/W bit (which is a logic low) are clocked onto the bus by the master transmitter. This indicates to the addressed slave receiver that the address high byte will follow once it has generated an Acknowledge bit during the ninth clock cycle.

PAGE 10
24AA64F/24LC64F/24FC64F 7.0 ACKNOWLEDGE POLLING Since the device will not acknowledge during a write cycle, this can be used to determine when the cycle is complete (this feature can be used to maximize bus throughput). Once the Stop condition for a Write command has been issued from the master, the device initiates the internally-timed write cycle and ACK polling can then be initiated immediately.
PAGE 11
24AA64F/24LC64F/24FC64F 8.0 READ OPERATION Read operations are initiated in the same way as write operations, with the exception that the R/W bit of the control byte is set to one. There are three basic types of read operations: current address read, random read and sequential read. 8.1 Current Address Read The 24XX64F contains an address counter that maintains the address of the last word accessed, internally incremented by one.
