137 / 222 page  Electrostatic discharge (ESD) Electrostatic discharges (a positive then a negative pulse separated by 1 second) are applied to the pins of each sample according to each pin combination. The sample size depends on the number of supply pins in the device (3 parts × (n+1) supply pins). This test conforms to the ANSI/JEDEC standard. Table 83. ESD absolute maximum ratings Specified by design and not tested in production. Symbol Ratings Conditions Packages PINs Class Max Unit VESD(HBM) Electrostatic discharge voltage (human body model) TA = 25°C conforming to ANSI/ESDA/JEDEC JS- 001 All - 2 2000 V VESD(CDM) Electrostatic discharge voltage (charge device model) TA = 25°C conforming to ANSI/ESDA/JEDEC JS- 002 LQFP100 LDO & SMPS - C1 250 UFQFPN 48 LDO & SMPS - C2a 500 UFQFPN 32 UFBGA100 LDO & SMPS WLCSP68(1) and WLCSP52 LQFP64 LQFP48 SMPS UFBGA64 LDO & SMPS - TBD TBD LQFP48 LDO All except PA3 C2a 500 PA3 C1 250 1. For both WLCSP68 packages, WLCSP68-G and WLCSP68-Q. Static latch-up The following complementary static tests are required on three parts to assess the latch-up performance: • A supply overvoltage is applied to each power supply pin. • A current injection is applied to each input, output, and configurable I/O pin. These tests are compliant with EIA/JESD 78E IC latch-up standard. Table 84. Electrical sensitivities Symbol Parameter Conditions Class LU Static latch-up class TJ = 110°C conforming to JESD78 2 5.3.13 I/O current injection characteristics As a general rule, the current injection to the I/O pins, due to external voltage below VSS or above VDDIOx (for standard, 3.3 V ‑capable I/O pins) must be avoided during normal product operation. However, in order to give an indication of the robustness of the microcontroller if abnormal injection accidentally happens, some susceptibility tests are performed on a sample basis during the device characterization.
