VALUE (Legacy Chip) VALUE (New Chip) UNIT
V(ESD) Electrostatic discharge Human body model (HBM), per ANSI/ESDA/JEDEC JS-001 (Pin 1,2 and 5) (1) ±2000 ±3000 V
Human body model (HBM), per ANSI/ESDA/JEDEC JS-001 (Pin 3 and 4) (1) ±1000
Charged device model (CDM), per JEDEC specification JESD22-C101(2) N/A ±1000
(1) JEDEC document JEP155 states that 2-kV HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 500-V CDM allows safe manufacturing with a standard ESD control process.
