1.Maximum condition for tpr, tpo, and tpv: wcs model, 1.1 V, IO 3.0 V and 105 °C. Minimum condition for tpr, tpo, and tpv: bcs
model, 1.3 V, IO 3.6 V and –40 °C. Input transition time from core is 1ns (20%–80%).
2. Minimum condition for tps: wcs model, 1.1 V, IO 3.0 V and 105 °C. tps is measured between VIL to VIH for rising edge and
between VIH to VIL for falling edge.
3. Maximum condition for tdit: bcs model, 1.3 V, IO 3.6 V and –40 °C.
4. Maximum condition for tpi and trfi: wcs model, 1.1 V, IO 3.0 V and 105 °C. Minimum condition for tpi and trfi: bcs model, 1.3 V,
IO 3.6 V and –40 °C. Input transition time from pad is 5ns (20%–80%).
5. Hysteresis mode is recommended for input with transition time greater than 25 ns.
3.6.3
DDR I/O AC Parameters
The DDR pad type is configured by the IOMUXC_SW_PAD_CTL_GRP_DDRTYPE register (see
Chapter 4, “External Signals and Pin Multiplexing,” in the i.MX25 Multimedia Applications Processor
Reference Manual).
3.6.3.1
DDR_TYPE = 00 Standard Setting I/O AC Parameters and Requirements
Table 24 shows AC parameters for mobile DDR I/O. These settings are suitable for mDDR and DDR2
1.8V (
± 5%) applications.
