Dual UART with I2C-bus/SPI interface, 64-byte FIFOs, IrDA SIR
14. Dynamic characteristics
[1]
A detailed description of the I2C-bus specification, with applications, is given in user manual UM10204: “I2C-bus specification and user
manual”. This may be found at www.nxp.com/documents/user_manual/UM10204.pdf.
[2]
Minimum SCL clock frequency is limited by the bus time-out feature, which resets the serial bus interface if SDA is held LOW for a
minimum of 25 ms.
[3]
2 XTAL1 clock cycles or 3
s, whichever is less.
Table 37.
All the timing limits are valid within the operating supply voltage, ambient temperature range and output load;
VDD =2.5 V 0.2 V, Tamb = 40 Cto+85 C; or VDD =3.3 V 0.3 V, Tamb = 40 Cto +95 C; VIL and VIH refer to input
voltage of VSS to VDD. All output load = 25 pF, except SDA output load = 400 pF.
