Input capacitance
Notes: 1. The SHI inputs are: MOSI/HA0, SS/HA2, MISO/SDA, SCK/SCL, and HREQ.
2. In order to obtain these results, all inputs must be terminated (i.e., not allowed to float). PLL signals are
disabled during Stop state.
3. Periodically sampled and not 100% tested
4. Maximum values are derived using the methodology described in
application dependent and may vary widely from these numbers.
AC ELECTRICAL CHARACTERISTICS
The timing waveforms in the AC Electrical Characteristics are tested with a V
maximum of 0.5 V and a V
MODA, MODB, MODC, and SHI pins (MOSI/HA0, SS/HA2, MISO/SDA, SCK/
SCL, HREQ). These pins are tested using the input levels set forth in the DC Electrical
Characteristics. AC timing specifications that are referenced to a device input signal
are measured in production with respect to the 50% point of the respective input
signal's transition. DSP56007 output levels are measured with the production test
machine V
OL
All output delays are given for a 50 pF load unless otherwise specified.
For load capacitance greater than 50 pF, the drive capability of the output pins
typically decreases linearly:
1. At 1.5 ns per 10 pF of additional capacitance at all output pins except
MOSI/HA0, MISO/SDA, SCK/SCL, HREQ
2. At 1.0 ns per 10 pF of additional capacitance at output pins MOSI/HA0,
MISO/SDA, SCK/SCL, HREQ (in SPI mode only)
