NV34C04 EEPROM Serial 4-Kb SPD Automotive Grade 1 for DDR4 DIMM Description www.onsemi.com The NV34C04 is a EEPROM Serial 4Kb, which implements the JEDEC JC42.4 (EE1004v) Serial Presence Detect (SPD) specification for DDR4 DIMMs and supports the Standard (100 kHz), 2 1 1 Fast (400 kHz) and Fast Plus (1 MHz) I C protocols. UDFN8 UDFN8 One of the two available 2Kb EEPROM banks (referred to as SPD MU3 SUFFIX MUW3 SUFFIX pages in the EE1004v specification) is activated for access at CASE 517AZ CASE 517DH powerup. After powerup, banks can be switched via software command. Each of the four 1Kb EEPROM blocks can be Write PIN CONFIGURATION Protected by software command. 1 V A 0 CC Features A WP 1 JEDEC JC42.4 (EE1004v) Serial Presence Detect (SPD) Compliant (Top View) A SCL 2 Automotive Grade 1 Temperature Range: 40C to +125C V SDA SS Supply Range: 1.7 V 3.6 V UDFN (MU3, MUW3) 2 I C / SMBus Interface For the location of Pin 1, please consult the Schmitt Triggers and Noise Suppression Filters on SCL and SDA corresponding package drawing.

ABSOLUTE MAXIMUM RATINGS Parameter Rating Units Operating Temperature 45 to +130 C Storage Temperature 65 to +150 C Voltage on any pin (except A ) with respect to Ground (Note 1) 0.5 to +6.5 V 0 Voltage on pin A with respect to Ground 0.5 to +10.5 V 0 Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected. 1. The DC input voltage on any pin should not be lower than 0.5 V or higher than V + 0.5 V. The A pin can be raised to a HV level for SWP CC 0 command execution. SCL and SDA inputs can be raised to the maximum limit, irrespective of V . CC Table 2.
