6.11.1 Filtering of RESET_N pin
The RESET_N pin is sensitive to noise and can cause unintended reset of the chip. For a long reset
line add an external RC filter with values 1 nF and 2.7 kΩ close to the RESET_N pin. When doing
this, note that the RESET_N low width (the shortest pulse that is guaranteed to be recognized as a
reset pin request) is longer than stated in Table 19.
6.12 SPI AC Characteristics
T_A = 25°C, VDD = 3.0V if nothing else stated. All measurement results are obtained using the
CC2510EM reference designs ([1]).
