STM6502 has two combined Smart Reset inputs ( SR0 and SR1 ) with delayed Smart Reset setup time (t SRC ) programmed by an external capacitor on the SRC pin. STM6503 is similar to STM6502, has two combined delayed Smart Reset inputs ( SR0 , SR1 ) and three user-selectable delayed Smart Reset setup time (t SRC ) options of 2 s, 6 s and 10 s through a three-state TSR input pin: when connected to ground, t SRC = 2 s; when left open, t SRC = 6 s; when connected to V CC , t SRC = 10 s (all the times are minimum). STM6504 has two independent Smart Reset inputs. SR0 provides the delayed Smart Reset setup time (t SRC ) function with three user-selectable t SRC options through a three-state TSR input pin: when connected to ground, t SRC = 2 s; when left open, t SRC = 6 s; when connected to V CC , t SRC = 10 s (all the times are minimum). SRE provides instant reset. SRE is edge-triggered with a special debounce time (t DEBOUNCE = 240 ms min.) at the falling edge after a valid reset period. STM6505 has two combined delayed Smart Reset inputs ( SR0 , SR1 ) and provides an adjustable reset delay setup time via an external capacitor connected to the SRC pin. The RST output depends also on the V CC monitoring threshold. STM6505 also provides independent low battery detect ( BLD ) output controlled by the secondary external input voltage V BAT . V BAT is monitored for low voltage and provides an indication on the battery low detect output pin ( BLD ). V BAT threshold is 1.25 V, fixed, and an external resistor divider is to be used to set the actual battery voltage threshold. V BAT threshold hysteresis is 8 mV typ. (16 mV max.). V BAT is voltage monitoring input only, the device is powered only from the V CC pin; V CC must be ≥ 1.575 V for proper operation of the V BAT comparator.
