• Manufacturer Part Number: STTS2002_11
• Description: 2.3 V memory module temperature sensor with a 2 Kb SPD EEPROM
• Manufacturer: STMICROELECTRONICS [STMicroelectronics]

STTS2002
Table 2.
1. STTS2002 will not initiate clock stretching which is an I
2. Guaranteed by design and characterization, not necessarily tested.
3. For a restart condition, or following a WRITE cycle.
4. This parameter reflects maximum WRITE time for EEPROM.
5. Bus timeout value supported depends on setting of TMOUT bit 6 in capability register.

Repeated start condition setup time
Hold time after (repeated) start condition. After this
period, the first clock cycle is generated.
Stop condition setup time
Bus free time between stop (P) and start (S) conditions
