58 / 106 page ![]() Electrical characteristics STM8AF6213/23/23A/26 58/106 DocID025118 Rev 5 9.3.1 VCAP external capacitor Stabilization for the main regulator is achieved connecting an external capacitor CEXT to the VCAP pin. CEXT is specified in Table 26. Care should be taken to limit the series inductance to less than 15 nH. Figure 10. External capacitor CEXT 1. Legend: ESR is the equivalent series resistance and ESL is the equivalent inductance. 9.3.2 Supply current characteristics The current consumption is measured as described in Section 4.3: Interrupt controller. Total current consumption in run mode The MCU is placed under the following conditions: All I/O pins in input mode with a static value at VDD or VSS (no load) All peripherals are disabled (clock stopped by peripheral clock gating registers) except if explicitly mentioned. Subject to general operating conditions for VDD and TA. Unless otherwise specified, data are based on characterization results, and not tested in production. Table 28. Total current consumption with code execution in run mode at VDD = 5 V Symbol Parameter Conditions Typ Max Unit IDD(RUN) Supply current in run mode, code executed from RAM fCPU = fMASTER = 16 MHz HSE crystal osc.
