Read Operations

Immediate Read

Upon power−up, the address counters for both the

Temperature Sensor (TS) and on−board EEPROM are

initialized to 00h. The TS address counter will thus point to

the Capability Register and the EEPROM address counter

will point to the first location in memory. The two address

counters may be updated by subsequent operations.

A CAT34TS02 presented with a Slave address containing

a ‘1’ in the R/W position will acknowledge the Slave address

and will then start transmitting data being pointed at by the

current EEPROM data or respectively TS register address

counter. The Master stops this transmission by responding

with NoACK, followed by a STOP (Figure 28).

Selective Read

The Read operation can be started at an address different

from the one stored in the respective address counters, by

preceding the Immediate Read sequence with a ‘data less’

Write operation. The Master sends out a START, Slave

address and address byte, but rather than following up with

data (as in a Write operation), the Master then issues another

START and continuous with an Immediate Read sequence

(Figure 29).

Sequential EEPROM Read

EEPROM data can be read out indefinitely, as long as the

Master responds with ACK (Figure 30). The internal address

count is automatically incremented after every data byte sent

to the bus. If the end of memory is reached during continuous

Read, then the address counter ‘wraps−around’ to beginning

of memory, etc. Sequential Read works with either

Immediate Read or Selective Read, the only difference

being that in the latter case the starting address is

intentionally updated.
