Output AC characteristics definition 1x Fmax Maximum frequency All I/Os, CL = 50 pF, 2.7 V ≤ VDDIOx ≤ 3.6 V - 40 MHz All I/Os, CL = 50 pF, 1.58 V ≤ VDDIOx < 2.7 V - 20 tr/tf Output rise and fall time All I/Os, CL = 50 pF, 2.7 V ≤ VDDIOx ≤ 3.6 V - 8 ns All I/Os, CL = 50 pF, 1.58 V ≤ VDDIOx < 2.7 V - 17 1. Specified by design. Not tested in production. 2. The I/O speed is configured using the OSPEEDRy[1:0] bits. Refer to the product reference manual for a description of GPIO port configuration register. Table 89. Output AC characteristics for FT_c I/Os(1)(2) (continued) Speed Symbol Parameter Conditions Min Max Unit Table 90. Output AC characteristics for FT_t I/Os in VBAT mode, and for FT_o I/Os(1) Symbol Parameter Conditions Min Max Unit Fmax Maximum frequency CL = 50 pF, 2.7 V ≤ VBAT ≤ 3.6 V, VDD off - 0.5 MHz CL = 50 pF, 1.58 V ≤ VBAT < 2.7 V, VDD off - 0.25 tr/tf Output rise and fall time CL = 50 pF, 2.7 V ≤ VBAT ≤ 3.6 V, VDD off - 400 ns CL = 50 pF, 1.58 V ≤ VBAT < 2.7 V, VDD off - 900 1.
