240 / 278 page ![]() Electrical characteristics STM32U535xx 240/278 DS14217 Rev 1 5.3.30 PSSI characteristics Unless otherwise specified, the parameters given in the table below are derived from tests performed under the ambient temperature, fHCLK frequency and VDD supply voltage summarized in Table 32, with the following configuration: • Output speed set to OSPEEDRy[1:0] = 10 • PSSI_PDCK polarity: falling • PSSI_RDY and PSSI_DE polarity: low • Bus width: 16 lines • Data width: 32 bits • Capacitive load CL = 30 pF • Measurement points done at 0.5 × VDD level • I/O compensation cell activated • HSLV activated when VDD ≤ 2.7 V • Voltage scaling range 1 Table 119. PSSI transmit characteristics(1) Symbol Parameter Conditions Min Max Unit - Frequency ratio DCMI_PDCK/fHCLK -- 0.4 - PSSI_PDCK PSSI clock input 2.7 V ≤ VDD ≤ 3.6 V - 64(2) MHz 1.71 V ≤ VDD ≤ 3.6 V - 47(2) DPIXEL PSSI clock input duty cycle - 30 70 % tOV(DATA) Data output valid time 2.7 V ≤ VDD ≤ 3.6 V - 14 ns 1.71 V ≤ VDD ≤ 3.6 V - 21 tOH(DATA) Data output hold time 1.71 V ≤ VDD ≤ 3.6 V 7- tOV(DE) DE output valid time - 12.5 tOH(DE) DE output hold time 6 - tSU(RDY) RDY input setup time 1.71 V ≤ VDD ≤ 3.6 V 0- tH(RDY) RDY input hold time 0 - 1. Evaluated by characterization. Not tested in production. 2. This maximal frequency does not consider receiver setup and hold timings. |
