142 / 232 page  Electrical characteristics STM32G474xB STM32G474xC STM32G474xE 142/232 DS12288 Rev 1 5.3.17 Extended interrupt and event controller input (EXTI) characteristics The pulse on the interrupt input must have a minimal length in order to guarantee that it is detected by the event controller. Table 65. HRTIM output response to external events 1 to 10 (Synchronous mode (1)) Symbol Parameter Conditions Min. Typ. Max.(2) Unit tLAT(DEEV) Digital external event response latency Propagation delay from HRTIM1_EEVx digital input to HRTIM_CHxy output pin (30pF load) (3) -56 66 ns tLAT(AEEV) Analog external event response latency Propagation delay from COMPx_INP input pin to HRTIM_CHxy output pin (30pF load) (3) -62 76 ns tW(EEV) Minimum external event pulse width -7 - - ns TJIT(EEV) External event response jitter Jitter of the delay from HRTIM1_EEVx digital input or COMPx_INP to HRTIM_CHxy output pin -- 1 tHRTIM (4) 1. EExFAST bit in HRTIM_EECR1 or HRTIM_EECR2 register is cleared (synchronous mode). External event filtering is disabled, i.e. EExF[3:0]=0000 in HRTIM_EECR2 register. Refer to Latency to external events paragraph in HRTIM section of RM0440. 2. Data based on characterization results, not tested in production. 3. This parameter is given for fHRTIM = 170 MHz. 4. THRTIM = 1 / fHRTIM with fHRTIM= 170 MHz. Table 66. HRTIM synchronization input / output(1) Symbol Parameter Conditions Min. Typ. Max. Unit tW(SYNCIN) Minimum pulse width on SYNCIN inputs, including HRTIM_SCIN -2 - - tHRTIM tRES(ESR) Response time to external synchronization request - --3 tHRTIM tW(SYNCOUT) Pulse width on HRTIM_SCOUT output -- 16 - tHRTIM fHRTIM=170 MHz - 94.1 - ns 1. Guaranteed by design, not tested in production. Table 67. EXTI input characteristics(1) 1. Guaranteed by design.
